Guide to applying or a building consent (simple residential buildings)



GUIDE TO APPLYING FOR A BUILDING CONSENT

The building consent is the oundation document

or any building project. It entitles you to carry out

building work in accordance with the plans and

specications submitted in your consent application.

It also provides ormal recognition that your plans

and specications meet the requirements o the

New Zealand Building Code, and thereore will

be built to meet certain perormance standards.

The Building Act 2004 increased the ocus on the

content and quality o the plans, specications and

documentation submitted or a building consent.

Getting the design, planning and documentation

right is the rst step in ensuring a building can be

built properly rst time.

To build well, all parts o the building process

need to work, rom the initial design and building

consent through to construction, inspection and

ongoing maintenance. Measures in the Building Act

are targeted at all parts o the building process.

Those who design and build will be licensed.

Councils and building consent authorities will be

accredited and registered. Product manuacturers

will be able to have their products certied

under the product certication scheme.

The Building Code is under review to ensure

perormance standards or buildings are clear and

meet people’s needs.

This guide will help you prepare plans, specications

and documentation or a building consent

application. Every building project is dierent and

requires dierent documentation. Building consent

authorities have their own systems or processing

building consents, and the systems needed or

a large metro building consent authority will

remain dierent rom those or a small rural one.

Nevertheless, this guide aims to bring more

consistency into the sector, and proposes a broad

agreement on the orm and content o building

consent documentation.

GUIDE TO APPLYING FOR A BUILDING CONSENT 3

About this document

This guide has been prepared or people wishing

to apply or a building consent or:

• simple residential buildings

• new buildings, primarily.

Readers are expected to have some knowledge o

the Building Code and the building consent process.

WHO SHOULD READ THIS GUIDE?

This guide has been written to help designers,

builders, homeowners’ agents and developers

by explaining the minimum inormation needed

or a building consent application.

The inormation it contains may also be o interest

to others in the construction sector, particularly

product manuacturers, subcontractors, and

providers o specialist technical services.

It is not generally intended as a guide or homeowner-

applicants, because preparing documentation or

consent applications, particularly or new buildingprojects, requires a detailed knowledge o the

Building Code and building process.

This document has been prepared by the

Department o Building and Housing (the Department)

as guidance inormation in accordance with section

175 o the Building Act.

The recommendations and suggestions in this guide

are not mandatory and not intended to be prescriptive.

This guide is not a substitute or proessional

advice, and should not be relied on as establishing

compliance with the Building Code. It is not a

Compliance Document under the Building Act 2004,and may be updated rom time to time. The latest

version is available rom the Department’s website

(www.dbh.govt.nz).



4 GUIDE TO APPLYING FOR A BUILDING CONSENT

Introduction

The owner o a proposed building has the

responsibility to make sure enough detail is provided

in the plans, specications and other documentation

or the building consent authority to issue a building

consent. Most applications or new building projects

are completed on behal o the owner by design

proessionals.

This guide ocuses on how to obtain approval

rom a building consent authority. It will help you

prepare plans, specications and documentation

or a building consent application. We have writ ten

it specically or simple residential building work,

such as new houses or townhouses. However,

the principles it contains can be applied to all

building projects.

The basic inormation needed or a building consent

application is similar across New Zealand. However,

each local council or building consent authority

processes applications slightly di erently, so there

may be variations rom one area to another.

For a building consent to be approved, you need to

demonstrate how the proposed building will comply

with the Building Code. It helps to remember that

the Building Code sets out only the minimum

perormance standards a building must meet.

In many cases, homeowners and designers will

strive or better standards.

It’s also important to remember that the building

consent authorities which approve applications

are looking or compliance with the Building Code.

It’s not their role to design the work or to monitor

quality and aesthetics, except where this aects

compliance with the Building Code.

The documentation or even a simple new building

project passes through many hands, includingdesigners, builders, plumbers, drainlayers,

homeowners and developers, and the building

consent authority.

Good planning and documentation provides a solid

oundation or everyone involved in the building

process. It should speed up processing and approval

times, and also provides an accurate historical

record that can be used later when urther work,

repair or maintenance is needed.

Providing adequate documentation will helpeveryone involved in a building project play their

part in ensuring the work is carried out properly,

rst time.




1.0 Background

. THE BUILDING ACT 2004

The Building Act 2004 increased ocus on the

content and quality o plans and specications

submitted or a building consent.

Section 45 o the Building Act sets out in broad

terms what an application or a building consent

must contain. However, it does not dene the orm,

content or quality o the plans and specications,

or other inormation needed to support an individual

application.The Building Act allows each building consent

authority to determine what plans, specications

and other inormation it reasonably requires.

This allows or dierences to be managed locally,

such as ways o storing and retrieving volumes

o applications. However, it has led to inconsistency

rom one authority to another. This situation

doesn’t provide certainty or you or or building

consent authorities.

We hope the approach set out in this guide willpromote greater consistency and eciency within

the sector.

.2 BUILDING CONSENT DOCUMENTATION

This guide includes recommendations on the

appropriate orm and minimum content or a building

consent application. This includes the drawings,

specications and accompanying documents

(other inormation), such as engineering calculations

and design reports. This guide also discusses

associated issues, such as the appropriate

role o manuacturers’ data, alternative design,

engineering and design calculations, product

appraisals, and various other orms o technical

statement or warranty.

Some building consent authorities have specic

requirements or building consent documentation,

including:

• specic size, orm and scale o individual

drawings or the elements they contain

• requirements or certain line types,

or thicknesses, or or lettering o a certain

type or size.

Oten these requirements are a result o the

building consent authority’s process or storing and

retrieving building consent inormation (or example,

digital storage). Although such requirements are

not related to the Building Code or Building Act,

it is useul to ask the building consent authority

about any specic requirements it may have beore

lodging your building consent application.




.3 COvERAGE OF DOCUMENTS

This guide ocuses on inormation needed

to conrm compliance with the Building Code.

However, inormation on tendering, contractual

issues, project management and construction,

and on those parts o a building project not requiring

Code compliance, can be included in a single set

o documents suitable both ‘or consent’ and

‘or construction’.

Building consent authorities may require other inormation,

due to area-specic matters (such as known ground and

environmental conditions), local district plan requirements,

bylaws, or Local Government Act 2002 requirements.

A project inormation memorandum (PIM) would identiy

any issues or you in advance.

due to area-specic matters (such as known ground and

environmental conditions), local district plan requirements,

bylaws, or Local Government Act 2002 requirements.

A project inormation memorandum (PIM) would identiy

any issues or you in advance.

.4 ADDITIONS AND ALTERATIONS

You can also apply the principles and

recommendations in this guide to projects involving

additions and alterations to an existing building.




2.0 The building consent process

A building project starts on site ater a building

consent has been issued and concludes when

a code compliance certicate is issued. Building

consent authorities check that the documents

submitted or a building consent conrm –

in accordance with section 49(1) o the Building Act

– ‘that the provisions o the Building Code would

be met i the building work were properly completed

in accordance with the plans and specications

that accompanied the application’.

Compliance with other requirements (such as

bylaws or a district plan) may be critical to the

design o the project, even though they’re not

part o the building consent process. Thereore,

you should consider these requirements as part

o your project management and design.

Building consent authorities should not suspend

building consent processing due to requests or

urther inormation or evidence on matters that

all outside compliance with the Building Code.

This type o inormation is not part o the buildingconsent process.

You will help the assessment process greatly i

you ensure the building consent documentation:

• includes a clear summary or report explaining

how compliance with each relevant clause

o the Building Code will be achieved,

including any waiver or modication sought

(reer to section 4.0 o this guide)

• dierentiates between items that relate

to the Building Code and those that relate

to contractual, tender and other Building Act

requirements

• includes a schedule or schedules o the materials,

products and systems (and their maintenancerequirements) proposed to be used in constructing

the building.

2. EARLY CONSULTATION

IS IMPORTANT

Early consultation between you, your designer and

the building consent authority plays an important

role. It helps reduce misunderstandings at the

time o application, as any specic document

requirements rom the building consent authoritycan be taken into account.

Obtaining a project inormation memorandum (PIM)

early in the process may reveal useul inormation

that helps the designer during their design work.

2.2 CODE COMPLIANCE CERTIFICATE

It’s important that all documentation relating to the

building consent is complete, precise and is an

accurate record o what has occurred on the site.

The owner must apply or a code compliance

certicate once the building work described in the

building consent, with any subsequent approved

amendments, has been completed.

The building consent authority must issue a code

compliance certicate where it is satised that thebuilding work complies with the building consent.

Where the building consent authority is not

satised, they may reuse to issue the code

compliance certicate.

Sale by a residential property deeloper

Under section 364 o the Building Act, residential property

developers (anyone building, or arranging to have built,

a household unit or the purpose o selling it) must get

a code compliance certicate beore completing the

sale, or allowing a purchaser to take possession o the

household unit. The exception to this is when the propertydeveloper and buyer sign Form 1 o the Building (Forms)

Regulations 2004. This orm is called ‘Agreement

between residential property developer and purchaser’.

This orm can’t be altered in any way.

This orm can’t be altered in any way.




3.0 Plans and specications

3. DEFINITION

The Building Act denes ‘plans and specications’

as ‘the drawings, specications and other

documents according to which a building is

proposed to be constructed, altered, demolished,

or removed’.

This denition doesn’t provide enough inormation

or you to determine how much or how lit tle detail

is needed and how the inormation should be

structured. Most building consent authorities willprovide guidance on the documentation you need

to submit with your building consent application

orms (this may include check sheets).

You also need to consider any application

inormation provided by the building consent

authority.

For the purposes o this guide, ‘other inormation’

includes but is not limited to:

• calculations

• manuacturers’ data

• technical opinions or appraisals

• codes o practice.

See section 7.0 o this guide or inormation on

these subjects.

3.2 BUILDING CONSENT INFORMATION

Inormation in the plans and specications needs

to be project-specic.

Using general phrases such as ‘reer to

manuacturer’s specication and/or requirements’

or ‘installed in accordance with best trade practice’

is not sucient. Manuacturers’ specications can

change rom time to time and ‘best trade practice’

is a standard that varies rom individual to individual.

Reerences to Standards and ComplianceDocuments need to be specic rather than general.

Some Standards are cited (in whole or in part)

in the Acceptable Solutions while other Standards

oer advice only. Some Standards may also

contain a range o options.

Make reerence to any Standards that are readily

available to those involved in the building process.

Reerences to other industry guides, such as

BRANZ publications, need to be specic and

not general.

Reerences need to:

• uniquely identiy documents with titles and dates

• be specic as to the paragraphs/clauses to

be ollowed.

Compliance Documents and Acceptable Solutions

The Building Code, being perormance-based, requires

a certain level o perormance to be achieved in buildings.

Unlike prescriptive bylaws that existed beore, it allows

more than one way to achieve that perormance. The

Acceptable Solutions provided in the Compliance

Documents (produced by the Department o Building and

Housing) provide one means o demonstrating compliance

with the Building Code. Building consent authorities must

accept Compliance Documents as complying with the

Building Code. Designers can provide an alternative

solution, as long as they demonstrate to the building

consent authority that the proposal will comply with the

Building Code.

A good project specication has a logical structure

and means o navigation. The deault standard

classication system or New Zealand is CBI

(Coordinated Building Inormation), recognised

by the 4-digit numbers used to classiy each

work section (ie, chapter) o the specication.

There should be a ‘Preliminaries’ and a ‘General’

section, ollowed by a series o technical work

sections, with each work section or chapter laid out

in a consistent pattern (such as ‘General’, ‘Products’,

‘Execution’, ‘Selections’) and with a consistent

clause numbering system.

Specications have typically been based on proprietary

model documents, or assembled by individual designers

in a modied trade-based ormat. Specication sections

have a long history o subdivision by trade (both traditional

and infuenced by NZS 4202: 1995 Standard Method

o Measurement o Building Works) or work sections

(based on CBI, a classication system modied rom

international practice by the Association or Coordinated

Building Inormation New Zealand).

3.3 DRAWINGS

All drawings should contain a drawing number

and title, the designer’s and owner’s name,

and job address, and be dated or version control.

Drawing conventions – line types and widths,

lettering type and size, symbols or building eatures

and elements, designation o spaces, representation

o materials and cross-reerencing conventions –

should generally conorm to AS/NZS 1100

Technical Drawing. Either hand-drawn or CAD

(computer-aided design) drawings are acceptable.

Drawing sizes may vary according to circumstance

and convenience, usually ranging rom A0 to A4.

The size o drawing sheets should be consistent

within a single set o project drawings. However,

occasionally drawings or diagrams o components

and construction details are more appropriately

provided in A4 size and bound in with specication

data (or example, a specic engineering detail).

The recognised Standard or architectural and engineering

drawing in New Zealand is set out in dierent parts under

AS/NZS 1100 Technical Drawing. This group o Standards

provides useul advice on drawing conventions.

While they do not provide a model or a typical set o

building consent documents or construction documents,

they nevertheless provide a good base to work rom.

3.4 DRAWING RANGE

The size and complexity o the project oten

determines the level or amount o detail needed,

and extent o associated structural and building

services-related documents. You can nd more

detailed inormation on the orm and content

o drawings in section 6.0 o this guide.

3.5 DIMENSIONS

AS/NZS 1100.301 sets out conventions ordimensions on drawings. Where a nished

dimension is critical or compliance or construction,

you should clearly identiy it in the relevant drawing

or specication. Timber size should be identied

by its actual nished size.

3.6 SPECIFICATION STRUCTURE




3.7 SPECIFICATION CONTENT

You should keep matters o tender, contract and

project management separate rom technical

matters, and rom the proposed product and

material selections. You can describe product

and material selections in each work section,

grouped together in a single ‘schedule’,

or list them on the drawings. A mix o trade-

based, material-based, process-based and

element-based sections or chapters is acceptable.

3.8 SPECIFICATIONS vERSUS

DRAWINGS

Your specication should complement the drawings,

not contain erroneous inormation and not contradict

itsel or associated documents. Inormation on

drawings need not be in the specication and

vice versa. Repeating the same inormation in two

places may lead to contradiction and conusion,

but may be useul or key points.

You should be able to decide how inormation

is presented and where it is located. Reasonable

requests made by the building consent authority

should be respected.

Sometimes inormation on timber sizes and

treatments is best placed on the drawings and

sometimes the specication may be the preerred

location. There will also be instances where project

selections – such as sanitary ttings or door

hardware – are best scheduled on the drawings,

alongside details o cabinetwork or kitchen/bathroom

xtures. In other cases such selections may be

better contained within the specication text.

You can also include certain drawn inormation in

a specication, such as ‘standard’ details o a catch

pit, or gully trap, a series o ‘standard’ reinorcing

details, or items or abrication o site. Wherever

you give this inormation in the document set,

it should be clear, correct and complete.

On a minor project, you can include the specication

data on the drawings or the convenience o both

the building consent authority and the builder.



GUIDE TO APPLYING FOR A BUILDING CONSENT

3.9 GRAMMAR AND LANGUAGE

A consistent approach to grammar and language

helps readability. Plain English and common words

are preerred. Avoid legalese and jargon.

The uture o documentation

Many designers are able to deliver, store and retrieve

documents electronically. Some building consent

authorities can also process and store building consent

applications in electronic orm. I you have suitable

technology, you should ask the building consent authority

i your application can be lodged electronically. Not only

can this reduce the cost and inconvenience o exchanging

inormation, it can also prevent problems with accessing

and interpreting hard copy or scanned documents.




A design summary is a tabulated listing o how

you propose to comply with each o the relevant

Building Code clauses. A design summary is not

mandatory, but does have several benets. It can:

• help the designer (during the documentation

phase) and the building consent authority

(during the building consent phase)

by providing a checklist against compliance

with the Building Code

• conrm which parts o the project are

compliance-related, as opposed to construction-

or contract-related only

• provide a checklist during construction,

clariying which changes will require a variation,

amendment or a new building consent

• provide a useul checklist (where it is kept up

to date) or the building consent authority

to consider Code compliance ater the project

is complete.

How much inormation is needed?

The purpose o building consent documentation is to

demonstrate, to the satisaction o the building consent

authority, that all relevant perormance requirements

o the Building Code are met. How extensive the plans,

specications and related inormation need to be depends

on the complexity and size o the project and how

closely the design conorms with Acceptable Solutions

or Verication Methods in the Compliance Documents

or the Building Code. In some cases, you may need to

describe how Code compliance is achieved or individual

building elements where the element must comply with

a variety o Code clauses (or example, a boundary wall

that is re-rated, provides bracing, has sound-control

properties and is located in a wet area).

4.0 Design summary

4. COMPLIANCE WITH BUILDING CODE

CLAUSES

Take care to ensure all relevant clauses o the

Building Code are correctly identied and considered

during the design process. They need to be

identied on the building consent application orm

where appropriate (see section 8.0 o this guide).

I you use a design summary, you could make

specic reerence to the relevant clause o the

Building Code.

The relevant Building Code clauses or simple,

residential buildings are described below.

However, in each par ticular case you should

consult the Building Code to check that the

relevant perormance criteria have been met.

B Structure – demonstrating how the building

withstands likely loads, including wind, earthquake,

live and dead loads (people and building contents).

B2 Durability – conrming the use o materials

that will remain unctional or the minimum periodsspecied (5, 15 or at least 50 years).




C Fire Saety – demonstrating means o escape

and boundary separations.

D Access Routes – the saety o entry/exit to the

building and the saety o any internal or external

stairs and slip resistance.

E Surace Water – the method o disposal o,

or example, rainwater rom external suraces,

and conrmation that surace water cannot enter

the building.

E2 External Moisture – conrming that the designand detailing o all external roo and wall claddings

and external openings will prevent external moisture

rom causing undue dampness or damage.

E3 Internal Moisture – conrming that suraces

in wet areas are durable enough, easily cleaned and

designed to resist moisture, and that ventilation and

the space temperature are sucient to avoid the

excessive build-up o moisture.

F Hazardous Agents on Site – identiying and

neutralising any hazardous agents or other

contamination o the building site.

F2 Hazardous Building Materials – conrming

the appropriate selection o glass and glazing

methods to ensure the saety o building users.

It also considers building materials that give o

noxious umes.

F4 Saety rom Falling – conrming the sae

design o all barriers (including handrails and

balustrades) inside and outside the building

(note: includes the design o swimming pool ences

under the Fencing o Swimming Pools Act 1987).

G Personal Hygiene – providing sucient sanitary

xtures (toilets, showers and basins) or cleanliness.

G2 Laundering – providing sucient laundry

acilities.

G3 Food Preparation and Preention o

Contamination – providing sucient sae and

hygienic acilities or ood storage and preparation.

G4 ventilation – conrming required natural

or orced ventilation to all occupied spaces.

G7 Natural Light – conrming that sucient

natural light is provided to occupied spaces and

providing appropriate visual awareness or the

occupants.

G8 Artifcial Light – conrming the provision

o minimum light levels in occupied spaces.

G9 Electricity – conrming sae distribution and

use o electricity.

G0 Piped Serices – conrming the sae

distribution o gas.

G Gas as an Energy Source – conrming the

sae installation o gas-powered appliances.

G2 Water Supplies – conrming the sae

supply (avoidance o scalding and backfow),

storage, reticulation and, where needed,

heating o potable water.

G3 Foul Water – conrming the sae and sanitary

collection and disposal o oul water and the

prevention o oul air rom entering the building.H Energy Efciency – conrming the provision o

a warm, dry interior environment through insulation

and controlling air movement, and the ecient use

o energy.




Using general details or a general statement

o compliance with the Building Code in the

specication is not sucient to demonstrate

compliance. The drawings and the details they

contain must be specic to the project. You should

clearly identiy in the specication the particular

materials and/or systems you intend to use.

Manuacturers’ inormation

The Acceptable Solutions and Verication Methods

in the Compliance Documents do not reerence specicbranded products or systems. However, brand-specic

products and systems can be proposed to demonstrate

compliance with the Building Code. Once the building

consent has been issued, any changes to the specic

products or systems named in the application will need

to be approved by the building consent authority.

4.2 GENERAL COMPLIANCE ISSUES

Simply stating that a project complies with the

Building Code is not sucient. You need to show

how the project complies. For example, or a simple

residential building the perormance requirements

o Clauses B1 and B2 can be achieved by

demonstrating compliance with NZS 3604 Timber

Framed Buildings and NZS 3602 Timber and

Wood Based Products or Use in Building, which are

reerenced in B1/AS1 and B2/AS1 o the B1 and B2

Compliance Documents respectively.

Where a part o the design does not comply with

the chosen Acceptable Solution, you will need

to demonstrate how that particular element or

part element complies with the Building Code.

Where a product is not needed to achieve compliance

with the Building Code, you may describe it generically.

Manuacturers should, as a matter o good practice,

ensure the data sheets they provide to designers,

speciers and builders are clearly dated and include only

relevant technical data on the selected material or product.

Be mindul that some materials and products contain

mixed technical and marketing data. (Reer to AS/NZS

1388 Guidelines or Technical Inormation or Building

and Construction Products.)

6.6 CONSTRUCTION DETAILS

The descriptions are not exhaustive but are typical o what is

required in the drawings. Some o the inormation recommended

in the ollowing drawings is not related to the Building Code but

will help the territorial authority to determine whether the work

breaches or needs approval under other legislation, such as bylaws

or the Resource Management Act. Additional inormation o this

type is shown in text boxes.





6.1 Site plan

The purpose o a site plan is to show the dimensions

and orm o the site, the proposed building work,

and where on the site the building will be located.

You should also include any known inormation

on existing and proposed services.

Drainage inormation in a diagrammatic orm could

be included on the site plan. This should show

both existing and new stormwater, sewer and relie

drainage pipework and ttings. You should also

detail how you propose that these services will

connect with the network utility operators’ systems,or can discharge into an approved on-site drainage

system (soakage and/or treatment).

Additional inormation

Show distances rom building work to boundaries,

and include a north point.

It’s helpul to include the site’s legal description,

building area (in square metres) and site area.

When preparing the plan, check with the building consent

authority and network utility operators or inormation on

the location o existing services both to and across the site.

Include a site datum. This may be a manhole cover

or similar on the site or in the street. The builder may

need to establish and maintain a new site datum.

Including calculations or site coverage on the site plan

will help the territorial authority determine compliance

with district plan requirements.

Note 1 Drawings may be combined.

Note 2 Requirements may dier where the building project is an alteration or addition to an existing building.

Note 3 For rural and/or larger sites a 1:500 (or 1:1000) location plan may be needed to conrm the site location.

Note 4 A scale o 1:500 or 1:100 may be adequate in some cases.

6.2 Foundation plan

The purpose o the oundation plan is to show the

building consent authority and the practitioner or

constructor what type(s) o oundation you propose,

and to detail their individual dimensions.


The plan should include the nished foor height(s)

in relation to the site datum. Where the property is located

in a food zone, conrm the relationship between the site

datum and the minimum occupied foor level set by the

territorial authority in the district plan.

Where oundations are designed by a registered engineer,supporting inormation should be provided, including

calculations, design assumptions (eg, soil bearing) and

possibly a producer statement or design. You should

identiy details o inspections and tests to be carried out

by the design engineer on the building consent application

under the heading ‘Proposed owner inspections’.



Note 3 A scale o 1:50 may be needed where oundations are relatively complex.

Note 4 Provided it is clear as to what is required, it may not be necessary to show each and every foor joist.

6.3 Floor plan

The purpose o the foor plan(s) is to provide

details o room types and sizes, the layout and

location o the internal elements, and the location

o all xtures and ttings.


Show and describe the bracing elements and lintels

on the foor plan. Where foor plans are complex,

use a separate key plan containing just the critical

structural inormation, such as bracing elements and

lintels, to avoid cluttering the foor plans.

Provide reerence numbers or all windows and doorsshown on the plans that may be scheduled elsewhere

on the drawing set, or in the specication.

Separate electrical plans, detailing electrical xtures and

ttings, are sometimes justied. Show any installations

related to the building consent, such as smoke alarms

and ventilation ans.

Where the building work is an addition or alteration to an

existing building, the foor plan should clearly distinguish

between the proposed new and the existing building work.



Note 3 A scale o 1:100 may be adequate or a simple project. A separate plan must be provided or each level o the building.

Where the lower foor is timber ramed, a oundation plan will be neede d to clariy the oundation layout (see s ection 6.2 o this guide).

6.5 Sections

The purpose o sections is to show all vertical andhorizontal building elements and the relationship o

the ground, foors, ceilings and roos to each other,

and to detail structural raming and other

construction elements.


Sections and details can be combined on the same

drawing, i appropriate. This can oten improve clarity or

those using the drawings, especially i details are shown

in their relative position to an accompanying cross-section.

You can use sections to more accurately locate details.

When o a suitable scale, sections can be used to detail

elements such as staircases, decks and balustrades.



Note 3 The number o cross-sections provided must be adequate to show all vertical relationships.

Location o cross-sections should be shown on foor plans.

Note 4 A scale o 1:20 may be used in some cases.

6.6 Construction details

The purpose o construction details is to ullydescribe junctions and interaces between and

within all major building elements. You need

to provide details or all relevant Building Code

clauses, including structural and weatherproong

design, and all necessary inormation about the

construction needed.


You can combine sections and details on the same

drawing. This can improve clarity, especially i details

are shown in their relative position to an accompanying

cross-section.

A range o scales rom 1:10 to 1:2 may be justied,

depending on the complexity o the material relationships

within the element being described. The detail needs

to identiy critical dimensions.

It’s sensible to group the details o common materials

on the same drawing, such as all exterior window

and door details.

6.7 Additional drawings

It may not always be possible to adequately describeor show clearly the ull level o detail required on the

drawings discussed in sections 6.1 to 6.6 o this

guide. You may need to provide additional drawings,

such as the ollowing.

LOCATION PLAN

A location plan is a high-level ‘bird’s eye view’

o the area surrounding the proposed construction

work. It shows the location o the proposed

work in relation to adjoining streets or proper ties.

These plans are particularly useul in rural or remote

locations, or multi-unit residential complexes.

FLOOR FRAMING PLAN

This is required when foor joists do not ollow

a regular pattern, or specic structural requirements

need to be shown. It can include:

• foor beam and joist layouts and sizes, including

blocking, trimmer joists and boundary joists• drawings o specialty engineered timber and

timber/steel products (where these are detailed,

calculations and data sheets should be included

in the consent documentation).

ROOF/CEILING FRAMING PLAN

This is needed where a range o roo and ceiling

orms are involved or complex junctions occur.

It can include:

• a plan layout o all roo and ceiling raming

members and seating o trusses and beams

• drawings o timber trusses, and proprietary

timber and timber/steel (where these are

detailed, calculations and data sheets should

be included in the consent documentation).

ROOF PLAN

This is needed or complex roo orms, or where

a number o dierent roong types are used.

It can include:

• details o roo alls (direction and slope)

• location and size o all rainwater heads, scuppers,

internal gutters, spouting and downpipes

(including calculations).

ELEvATIONS OF EXT ERIOR OPENINGS

These are needed when window and door

elevations are not clearly shown on the wall

elevations. It can include:

• 1:50 elevations o each exterior window anddoor element layout

• details o glazing types and window opening

types, or reerence to the specication.

PROTECTION OF ADJOINING PROPERTIES

The building consent authority may require

inormation on how adjoining properties will be

protected rom the work being undertaken on site

(or example, surace water control, temporary

retaining wall, site hoarding or encing).

DETAILS OF SPECIALIST INSTALLATIONS

When these are needed, they can include:

• details o proprietary installations, such as

suspended concrete foors, precast concrete

panels, timber trusses, engineered timber

products and steel bracing rames

• drainage and plumbing schematics or buildings

that are more than one storey or where plumbingdesigns are complicated.

WET AREA DETAILS

These are needed to detail wall and foor nishes in

wet areas, such as kitchens, bathrooms or laundries.




7.0 Related issues

When applying to amend a building consent,

the application should include details o what was

originally approved and how it will be changed.

It must also demonstrate that the new proposal

complies with the Building Code and will not

aect other works’ compliance with the Code.

All variations to a building project that relate

to the Building Code must be notied to the

building consent authority, so it can approve and

record them. The nature o the change will infuence

the process that needs to be ollowed to have

the variation approved and recorded. Applications

or amendments should be made and approved

beore the change takes place.

I changes are unrecorded or not approved

by the building consent authority, the building

consent authority may issue a notice to x or

the variation and may also reuse to issue the

code compliance certicate.

Where building work includes constructing

a swimming pool (as dened by the Fencing

o Swimming Pools Act 1987), the pool must

be enced to comply with the requirements

o Clause F4 Saety rom Falling o the Building

Code. Fencing and pool construction details

establishing compliance will need to be included

with the consent documentation.

7. SOLID -FUEL HEATERS

Where solid-uel heaters are proposed as part

o the building work, the plans and specications

need to identiy the:

• appliance by brand and model

• proposed location o the appliance

• fue type

• location, fashing and installation details

• height o the top o the fue relative to ridge

lines and windows.

The joint Australian and New Zealand Standard

AS/NZS 2918: 2001 Domestic Solid Fuel Burning

Appliances – Installation is cited in C/AS1 as

an Acceptable Solution or installing domestic

solid-uel-burning appliances.

Any new pool, as dened in the Fencing o

Swimming Pools Act 1987, must comply with that Act.

Where a property already has a pool, it also must be

enced to comply with the Act. The Act also applies

to spa pools (including those with lockable lids).

The Resource Management Act 1991 sets out

requirements or replace emissions. Inormation on

appliances that have been tested to meet emission

requirements is available on www.me.govt.nz/laws/

standards/woodburners

7.2 THE FENCING OF SWIMMING POOLSACT 987

7.3 vARIATIONS AND AMENDMENTS




7.4 MANUFACTU RERS’ DATA(AND BRANDED vERSUS

GENERIC SPECIFYING)

Much o the inormation provided by product

manuacturers is o a general or marketing nature.

You should provide only relevant technical literature

that is sucient to show compliance with the

Building Code. Providing the entire technical

manual is unnecessary and inappropriate.

The building consent authority may request that

you provide specic technical data rom the product

manuacturer, accompanied by an independent

appraisal or verication that the product will meet

Building Code requirements. You should attach

this to the other documents submitted or building

consent approval.

7.5 FACTORY-MANUFACTUREDBUILDING ELEMENTS (ROOF

TRUSSES AND FLOORING SYSTEMS)

Beore the Building Act 2004, building consent

authorities were oten prepared to issue a building

consent based on outline inormation or proposed

actory-manuactured building elements, or example

roo trusses and fooring systems. Sometimes this

inormation would be supplemented with more

detailed inormation, ater abrication and beore

erection on site.

The Building Act 2004 has placed more emphasis

on the complete ‘or construction’ documentation

being supplied with an application or building

consent.

In many cases, designs or actory-manuactured

building elements were only supplied to the builder

when the goods were delivered. This is no longer

considered acceptable practice.

Building consent application

Beore lodging a building consent application,

you should obtain a buildable design rom

a abricator. This design needs to be attached

to the building consent application and submitted

to the building consent authority or approval.

Buildable designs show:

• proposed building elements

• proposed layout

• site-specic conditions (or example,wind zone, roo type, cladding type)

• where load-bearing walls and oundation

thickenings are required

• spans

• any specic lintel/beam requirements

• the timber grade.

Buildable designs are based on industry-accepted

computer design programs, which in turn are based

on relevant standards. The inormation should also

include the details o the abricator and the design

program and version used.




Construction

During the work phase, the abricator is likely to

visit the site to check all relevant measurements in

order to manuacture the trusses or fooring system.

The manuacturer will produce ‘shop drawings’,

which are highly detailed drawings or the

person who makes the trusses or fooring system.

They will also produce a series o on-site

instructions, and a layout plan or the person

who erects the building elements.

Once the installation has been completed,

the as-built inormation should be supplied to the

builder, designer and homeowner, and the building

consent authority or its records. The building

consent authority may place a note to this eect

on the building consent approval.

7.6 SERvICES PLANS

The Building Code requires that sanitary xtures

and sanitary appliances are provided with a sae and

adequate water supply, and an adequate plumbing

and drainage system.

At the time o the building consent application,

the building consent authority will require certain

inormation on the water supply system and the

oul water and surace water (stormwater) disposal

systems. It will also require documented assurance

that an adequate water supply is available and that

there are adequate means o disposal o both

oul water and stormwater. These can be either

by connections to a local council or network utility

operator’s system or, where these are not available,

within the building site.

On-site disposal systems may require additional approvals

under the Resource Management Act 1991.

Precisely how a water supply, or a waste oroul water disposal system, is to be laid out may not

be apparent when you apply or a building consent.

However, you should provide the location and

specication o all xtures and ttings, together with

a diagrammatic layout o oul and sur ace water

(stormwater) drainage. Schematic layouts o water

or waste-water pipework are not normally needed,

unless specic inormation is needed to conrm

compliance with the Building Code.

When the project is nished, the building consentauthority will ask you or an as-built drainage plan

or its records.

Where on-site disposal o oul water is proposed,

the means o compliance should be identied in

the design summary under the heading G14.




7.7 APPRAISALS, TECHNICALSTATEMENTS, CODES OF PRACTICE,

WARRANTIES AND GUARANTEES

A building consent authority may accept numerous

ways o veriying a product, material or system’s

perormance. These include:

• appraisals by specialist organisations

• test reports

• technical statements and opinions

• calculations (supported by producer statements)

by designers and/or manuacturers or installers

• codes o practice rom industry bodies.

The building consent authority may request

copies o warranties and guarantees (under contract,

or oered by product manuacturers) provided by

accredited or licensed installers and manuacturers.

This is in addition to specialist technical publications

and the technical data provided by product

manuacturers.

You and the building consent authority maychoose to rely on some or all o these mechanisms

to support or conrm compliance. However,

the building consent authority shouldn’t insist that

you provide a particular approach to, or a particular

means o veriying, your proposed design.

All such approaches to conrming compliance,

or to supporting an alternative solution proposal,

can be valid.

7.8 CALCULATIONS

When the perormance o a particular building

element needs to be calculated (eg, structural

beams and lintels, insulation or fow rates or

mechanical ventilation systems), these calculations

may need to be included with the documents

required or a building consent.

7.9 SMOKE ALARMS

All residential dwellings now require smoke alarms.The minimum requirement is or a battery-powered

device with a silence and test button. This also

applies to alterations to existing dwellings.




8.0 Application or project inormation memorandumand/or building consent

When applying or a building consent, you will needto apply or a project inormation memorandum

(PIM) at the same time, i you haven’t already

got one. The building consent authority provides

a orm (Form 2) that you can use or either or

both purposes.

This orm asks or details about the property,

the owners, who is undertaking various parts o the

work and a brie description o the proposed work.

The content and wording o Form 2 has been

prescribed in regulations. Building consent

authorities reproduce the orm and can add

additional requirements, as long as the orm has

the same eect and is not misleading. You must

ll out the application orm in ull and ensure

it is actually correct.

You can nd much o the property inormation

rom a rates demand, lease agreement, copy o

the certicate o title, or rom local council archive

records. I you seek inormation rom local council

records, separately or as part o an applicationor a PIM, charges may apply.

The description o the work proposed should beclear and precise. For example:

• ‘Addition o lounge, kitchen alterations and

new conservatory’ rather than ‘Additions and

alterations’.

• ‘New 100 m2 dwelling with two-car garaging,

associated earthworks and retaining walls’

rather than ‘New dwelling’.

Licensed building practitioners

From November 2009 it will be necessary to provide

certication rom the Design Lead licensed building

practitioner and to identiy the Site Lead licensed

building practitioner. From November 2011, it will also be

necessary to identiy the licensed building practitioners

that will certiy structure and envelope construction work.

Where the construction licensed building practitioners are

not known at the time o application, the building consent

authority will need to be inormed beore the work starts.

The Department will provide urther guidance material

on the licensed building practitioner regime.

Form 2 requires you to write a description o howyour project will comply with the Building Code.

You need only to provide a brie description.

Cable cars

Form 2 calls or inormation on ‘compliance schedules’

or buildings. This requirement does not relate to a stand-

alone residential dwelling, unless the dwelling has a cable

car attached to it or servicing it. From 2008, all buildings

with cable cars will need a compliance schedule.




9.0 Building inspection requirements

The building consent authority will need toundertake inspections while the building is being

built. Building consent authorities decide what

inspections they need to carry out based on their

evaluation o the plans, specications and other

inormation, including any proposed owner

inspections (or example, by an engineer).

These are the more common inspections

undertaken by a building consent authority.

• Pre-pour (beore concrete is poured, or example,

or piles, ootings, slabs, in situ walls or

blockwork inll)

• Tanking/waterproong (beore back-lling

retaining walls, covering membranes on decks

or laying tiles in wet areas such as showers)

• Pre-clad (beore wrapping the building in building

paper or building wrap and installing the cladding)

• Post-clad (beore applying coatings to bre

cement or polystyrene systems possibly

including inspections during the plastering)

• On completion o the cladding systems• Hal-high brick (where veneer is used)

• Pre-line (with insulation installed but beoreinstalling internal linings. This inspection may

include checking the plumbing installation

under pressure test. Where a domestic sprinkler

system has been installed in your dwelling a fow

test should be undertaken beore tting linings.)

• Post-line (checking bracing element xings

beore plastering and decorating)

• Drainage (beore lling in trenches and covering

the in-ground pipework. Pipework should be

under test or this inspection; drainage testing

can include smoke, air or water testing.)

• Final inspection or plumbing, building and

drainage work (once the work described in the

building consent is completed)

This list is not exhaustive. Dierent building consent

authorities have dierent inspection requirements,

depending on the size and complexity o each project.

You will nd it useul to have an understanding

o what inspections are needed and when they

are needed. Missed inspections may preventa building consent authority rom being able to

establish ull compliance with the building consent,

thereore preventing them rom issuing the code

compliance certicate.

It is not the role o the building consent authorityto control the quality o the building work beyond

ensuring it complies with the Building Code,

or to act as a clerk o works (site supervisor or

oreman) on the project.

When booking an inspection, give the building

consent authority as much notice as possible.

Provide inormation about the type o inspection

required, a contact name and phone number,

building consent number, and a clear address.

I the property is isolated or hard to nd,give adequate directions.

When on site, a building inspector will need copies

o the approved building consent documentation

and other approvals. Ensure the site is clean,

tidy and sae, and that a person with adequate

knowledge o the project is on site to answer

any questions.




10.0 Project planning

0. RESOURCE MANAGEMENTAND OTHER NON-BUILDING ACT

REQUIREMENTS

It is possible to obtain a building consent where the

work complies with the Building Code, but does

not comply with other legal requirements such

as a district plan or the Resource Management Act

1991. The work may not be able to proceed i there

is non-compliance and a resource consent can’t

be or hasn’t been obtained.

The Building Act also provides or the building

consent authority to withhold the code compliance

certicate i you haven’t paid development

contributions.

During the planning and design phase o the project,

you should contact your territorial authority and

discuss any relevant rules and resource consent

or other requirements. Pay particular attention

to site coverage, building height, and other bulk

and location requirements. It may be possible

to alter the design to ensure it complies with theResource Management Act 1991. The earlier you

are aware o this the better. Other matters you

can discuss with the territorial authority include

approvals or connections to local council services

(stormwater, sewer).

You need to give special consideration to therequirements o other acts when building:

• on steep slopes

• on waterront or riverside locations

• close to adjoining properties

• close to the ront boundary with the street

• over territorial authority services or network

utility operators’ systems

• under overhead transmission lines

• close to airports or ports

• driveways close to street corners• driveways o busy main roads

• where no drive-on access is available

• on sites requiring trees to be cleared

• in heritage or character precincts

• in or on land that may be contaminated

• in or on land subject to a natural hazard

(you should identiy these on the site or

location plan i you know about them beore

applying or your building consent).

You may nd it useul to apply or a projectinormation memorandum (PIM) beore developing

ull detailed drawings. The PIM gives early notice

o special requirements, including any development

contributions you need to pay.

The PIM can provide other useul inormation thatwill help you comply with the Building Code.

The project manager or designer engaged to

manage the project may handle these non-

Building-Act-related matters or you.

0.2 PRODUCT MANUFACTURERS’

INFORMATION

Inormation provided by manuacturers, their agents

or importers is o ten intended or marketing

purposes. Such inormation may not be sucient

product would meet specic requirements o the

Building Code.

Product manuacturers

Further guidance or product manuacturers on

the recommended orm and content o inormation

on branded products is set out in AS/NZS 1388

Guidelines or Technical Inormation or Building

and Construction Products.




0.3 ROOF TRUSS DESIGN

When seeking a buildable roo truss design rom

a abricator, the designer should provide the ollowing

inormation so the detailer can understand what the

roo will look like and how it will be supported.

• Dimensioned drawings showing elevations,

foor plans, cross-sections and oundation plans

• Details o barge, ascia and sot construction

• Ceiling orm and construction (or example,

plasterboard on timber battens)

• Wind zone, corrosion zone, earthquake zone

and snow loads (where applicable)

• Any additional loads that may be imposed on

the roo structure (in other words, ventilation

systems, solar water heaters, storage in the

roo space, large light ttings, or liting cradles

or people with disabilities)

• Proposed connectors rom trusses to the

raming top plate

• Any point loads

• Relevant inormation rom the specicationon the type o roo cladding (or example,

pressed steel tiles are light and clay tiles

are heavy) and its support (or example,

purlins or sarking)

• Roo pitch

A truss detailer consulted early in the designprocess can provide an easily built design.

They may also provide suggestions that would

ensure a simpler and cheaper roo, and clariy any

downstream eects on walls and oundations.




BUILDING ACT 2004

The Building Act 2004 is the Act o Parliament

that governs building work in New Zealand.

BUILDING CONSENT

Building consents give approval to undertake

building work. When a building consent is issued,

the work must be undertaken in accordance with

that consent.

BUILDING CONSENT AUTHORITY

The Building Act 2004 introduced a new entity to

undertake building consent and inspection unctions

called a building consent authority. It can be either

part o a territorial authority (local council) or regional

authority, or be a private company. All building

consent authorities will need to be registered and

accredited to perorm building control unctions.

In addition, they will be subject to regular external

independent accreditation audits to help ensurethey can adequately undertake their building control

unctions to certain standards.

For more inormation see the Depar tment o

Building and Housing’s website (www.dbh.govt.nz).

11.0 Glossary o terms

DEvELOPMENT CONTRIBUTION FEE

Territorial authorities can charge a development

contribution ee to those applying or a building

consent. These ees help the territorial authority

develop the inrastructure to support new

developments in the area.

LICENSED BUILDING PRACTITIONER

From 30 November 2007, licence classes will

be introduced or people working in certain areas

o design and building work. To get a licence,

people will have to show that they meet the national

standard or the licence class they apply or.

People can apply to become licensed and have their

name listed on a public register. Members o the

public can view this register and use it to choose

competent building and design practitioners who

have demonstrated they meet the national

standards.

From 30 November 2009 onwards, certain typeso work will need to be undertaken or supervised

by licensed building practitioners.

NEW ZEALAND BUILDING CODE

The New Zealand Building Code contains 35

technical clauses and sets minimum perormance

standards that buildings must comply with.

The Building Code Compliance Documents can be

downloaded rom the Department o Building and

Housing’s website (www.dbh.govt.nz).

NEW ZEALAND STANDARDS

Standards New Zealand provides a variety

o Standards or the building industry, covering

issues such as construction, testing, advice and

manuacturing. These can be obtained rom

Standards New Zealand (www.standards.co.nz).

NOTICE TO FIX

This is a legal notice issued by a building consent

authority when it has identied breaches o the

Building Act, such as carrying out building work

not in accordance with a building consent.Failing to comply with a notice to x is an oence

under the Building Act, and can incur an initial ne

up to $200,000, plus $20,000 or every day or

part day during which the oence continues.




PLANS AND DRAWINGS

The Standard NZMP 4212: 1998 Glossary

o Building Terms, published by Standards

New Zealand, denes a ‘plan’ as:

The top view or horizontal section o

an object as projected in orthographic

projection. Anything drawn or represented

on a horizontal plane, as a map or

as the horizontal section o a building.

NZMP separately denes a ‘drawing’ as:

(1) (Working) Drawings to scale or

dimensioned or the purpose o guiding

and controlling the making o parts

o the work as distinct rom a pictorial

presentation showing only the general

orm o the work.

(2) (Detail) A large scale drawing to give

inormation which cannot be shown on

small scale drawings or adequately

described in the specication.

PROJECT INFORMATION MEMORANDUM(PIM)

A project inormation memorandum is issued

by a territorial authority. It details any inormation

the territorial authority has that may aect your

proposed project, so it’s a useul document

to get beore completing design work.

TERRITORIAL AUTHORITY

Territorial authorities are commonly known as

local councils. They undertake the building control

unctions required by the Building Act 2004.
