1 Introduction

Airport Authority Hong Kong (AAHK) BIM Specification outlines minimum content

and process requirements, including the BIM Standard to be achieved and the

procedures and methods to be used and the expected level of details/development

of the BIM models.

Construction BIM Specification BIM 5/30

2 General Requirements

2.1 BIM Objectives

a) Airport Authority Hong Kong (AAHK) intends to integrate the Building

Information Modelling (BIM) process and deliverable into the organisational and

planning structure and take advantage of the data information created during

design and construction to enhance and feed into existing and future

facilities/operations processes to meet a common goal.

b) AAHK adopts BIM in order to:

Enhance design quality;

Achieve proper design coordination to ensure sufficiency of spatial provisions and eliminate clashes between design elements;

Verify buildability of major construction elements; and

Facilitate construction planning, improving efficiency of construction and avoiding delay, disruption and additional costs due to design errors, and thereby achieving project completion on time, within budget and to high quality standard.

c) AAHK’s projects typically involves multiple projects and disciplines. Each

project requires model coordination with the AAHK’s project management

team, after which cross-project and cross-discipline projects will go through

design coordination. As all projects have different goals and teams, a

customised BIM execution plan as a live document which may evolve as the

project progresses. To maximise the use of BIM, the entire process from

conception to as-built BIM shall be influenced by that end goal. All the team

members need to be aware of the downstream BIM uses and revise their inputs

into the model appropriately, all of which is established with a BIM execution

plan.

All AAHK projects are to utilise the BIM process for documentation and other uses

as defined herein. Some projects include:

Land Formation;

Airfield Works (Including Existing Runway Modification);

Third Runway Concourse (TRC) Building;

Automated People Mover System (APM), Baggage Handling System (BHS) and the Associated Tunnels and Ancillary Buildings;

T2 Expansion & Associated Infrastructure Works; and

Other Infrastructure and Facilities at Western and Eastern Support Area.

Fundamental to these goals is the base understanding that BIMs are not an after-

product from the design effort or construction effort. Models shall be the basis of

the design and construction documentation, and shall contain all information and

content that facilitates with interfacing collaboration and generates official

deliverables and drawings.

d) Without limiting the generality of the above primary BIM objectives, the

following is a list of some particular BIM objectives that are to be achieved:

Resolving all spatial and coordination issues before completion of the detailed design;

Resolving design discrepancies, mistakes, conflicts and clashes before tendering;

Managing design changes to minimise adverse impact on the follow-on construction activities;

Achieving programme and construction safety by using BIM to analyse programme requirements and constructability;

Visualising the design elements in a true representation of the actual condition so as to facilitate design coordination and construction planning;

Identifying and resolving temporal interferences among the different elements;

Checking critical dimensions to ensure no spatial conflicts and verify the buildability of the design;

Linking BIMs with construction programme to demonstrate the sequence of the work and programme impacts of major construction activities;

Linking the BIMs into a virtual reality (VR) environment to replicate real life situation; and

Producing BIMs for facility management after project completion.

2.2 AAHK BIM Documents

Upon contract award, the following documents shall be provided as guidelines

which shall be strictly followed, or templates which can be used for project-specific

BIM execution plan:

BIM Specification (this document)

BIM Standard describes in detail quality of model and protocols of using the collaboration site to share works (in progress or deliverables) in context of all AAHK projects.

BIM Uses comprehensively lists BIM uses relevant to AAHK, and can be used to communicate and define project-specific BIM uses.

BIM Matrix and LOD Spec outlines basic known model elements in model categories applicable to AAHK, and can be used by Contractors to prepare their project-specific BIM execution plan.

BIM Checklist are used by Contractors, AAHK and AAHK-designated BIM Consultant for each upload to verify the model completeness and quality.

BIM Process Map illustrates the relationship between key documents provided by AAHK, BIM uses and deliverables in construction stage, which involve AAHK and Contractors for model review.

AAHK AAMS Asset Code Specification is provided for Contractors to embed AAHK Asset code into BIM models and facilitate Contractors to provide project-specific Asset code list for AAHK’s review and approval.

4 Construction BIM Specification

Contractors may receive design BIM models for reference to understand design

intent. Subjected to the availability of the design BIM model, Contractors may use

design BIM model to develop their construction BIM model or start construction

BIM models based on the contract drawings. Contractors are responsible to rectify

and fix any errors, clashes and issues found from the design BIM model and finalise

the construction BIM model in compliance with this Document.

Construction BIM model shall, in nature, contain greater level of detail, for

additional purposes including but not limited to SQ process, construction-stage 4D

model simulation, construction method simulation, site safety management and

commissioning, while further preparing for future use of facility management in

operation stage.

4.1 Construction Change Management

Contractors shall indicate response protocol, timing, and incorporation of

responses into BIM files in their project-specific BIM execution plan.

Contractors are required to update and upload any changes originating from SQs,

Submittals and Bulletins that have changed their perspective work. Changes shall

be uploaded onto the collaboration site and send out a corresponding notice

indicating the changes and reasoning behind the change within no later than 10

business days from receipt of changes.

4.1.1 BIM Utilisation for SQ Process

The SQ template contains input boxes for confirmation of whether the response to

the SQ may require modification to BIM files. Modification may require geometric

model revision or information input.

The BIM issues item shall be a searchable item of the projects SQ log system.

Contractors are responsible for implementation of modifications to BIM files due to

SQ responses, and shall provide an update of the SQ Log to AAHK on a bi-weekly

basis. So long as change is approved by AAHK, both construction and model

revision shall be continued and executed in parallel.

4.1.2 BIM Utilisation for the Change Order or Bulletin Process

The process for quantifying and correcting clashes caused by a design change to

a signed off and in-progress area is as follows:

Contractors draft the revised 3D layout, minimising the clashes with other trades as much as possible. Revised layouts shall be drawn in an identifiable layer, labeled to match the respective bulletin.

Once the work is drafted, a clash report shall be prepared by the Contractor with all latest posts.

Construction BIM Specification BIM 20/30

Page 21: Construction BIM SpecificationBIM...BIM Checklist are used by Contractors, AAHK and AAHK-designated BIM Consultant for each upload to verify the model completeness and quality. BIM

1 Introduction

Airport Authority Hong Kong (AAHK) BIM Standard provides a unified foundation

for authoring, storage and sharing BIM content. It contains structured guidelines

for how to create, locate, name, edit, and publish BIM in context of all parties’

collaboration. Specific to AAHK’s requirements to implement Level 2 BIM for AAHK

Projects, this standard document can be adopted towards all future AAHK projects

utilising BIM.

The BIM Standard also serves as a detailed reference for other documents such

as BIM Specification and Appendix F - BIM Checklist.

For AAHK’s 2D drawing requirements, AAHK CADD STANDARD governs 2D

drawing authoring, while 2D drawing naming protocols governs 2D drawing

naming. This BIM Standard references, compliments and shall not deviate from the

latest version of AAHK CADD STANDARD and 2D drawing number protocols.

APPENDIX J

Contract T18W008 PS AJ D 5/56 (Addendum No.1) AA 07/12/18 Primary Sorter Replacement Works for Baggage Handling System

Particular Specification – Appendix J – Appendix D

The use of additional software (“third-party software"), proprietary or freeware, are

to be approved by AAHK prior to use. Any parties under contract with AAHK shall

inform AAHK and AAHK-designated BIM Consultant of any libraries, object

enablers, software plug-ins, 3D viewers, etc. required for AAHK to view their BIM

content. AAHK shall approve or reject with AAHK-designated BIM Consultant’s

advice based on functionalities, interoperability with AAHK-preferred software, cost

(one time and perpetual), and other risks (e.g. software’s future continuity,

liabilities). Upon approval, the required plug-ins shall be posted to collaboration site

for use of entire project team.

Alternate 3D simulation software shall be proposed to increase benefit of using

BIM and presentation. The necessity and project-specific strategy of such alternate

simulation software shall be presented to and approved by AAHK prior to use.

2.1.2. BIM Coordination and Clash Detection Software Requirements

In the event other software is used, the alternative software shall satisfy functional

requirements, including:

Displaying and saving 2D and 3D views compliant with this document;

Displaying and saving dynamic sectioning views;

Model federation by maintaining relative links between models with correct

relative folder structure;

file formats that can be exported from AAHK-preferred BIM software;

Generating clash detection results; and

Saving and exporting clash detection result log files.

2.2. Modelling Principles

While the detailed modelling methodologies may vary from project to project, the

following BIM modelling principles are universally applicable regardless of project

type, project scale and LOD.

2.2.1. Parametric-driven

Model elements shall be created dynamically, with their forms and appearances

shall be driven by parameters when possible.

For building models authored using Revit, the use of parameters such as

dimension, materials, shall be optimised. The use of Instance parameters and Type

parameters shall be balanced for model element management while allowing

flexibility to specify individual model elements’ attributes.

Regardless of whether AAHK-preferred software is used, AAHK- or SOS-required

non-graphic information shall be incorporated as parameters. With relevant

parameters in place, the use of schedules and tagging shall be optimised to sort,

audit and control visibility of model elements.

2.2.2. Connectivity

Page 104: Construction BIM SpecificationBIM...BIM Checklist are used by Contractors, AAHK and AAHK-designated BIM Consultant for each upload to verify the model completeness and quality. BIM

APPENDIX D TO

APPENDIX J

Contract T18W008 PS AJ D 6/56 (Addendum No.1) AA 07/12/18 Primary Sorter Replacement Works for Baggage Handling System

Particular Specification – Appendix J – Appendix D

Connectivity within systems shall be maintained, including and not limited to load-

bearing structural walls and columns, pipe networks, etc. Quality Control (QA)

procedures shall be conducted regularly to ensure and rectify connectivity.

2.2.3. Eliminating Overlapping Elements or Clashes

Overlapping elements adversely affect clash detection and quantity surveying

results, and shall be detected and eliminated.

Even before the projects reach the stage for clash report submission, routine clash

detection and visual checks shall be conducted as part of Quality Control process.

When resolving model elements overlaps, vertical structural continuity and system

continuity shall be preferred over horizontal or non-structural elements.

Regardless of project SOS, model elements’ hierarchy shall be consistent with

AAHK’s quantity surveying methodology and requirements, which determines the

cutting hierarchy between joining or overlapping elements.

2.2.4. Coherent Model Element Categorisation

Revit categories and Civil 3D object types shall be assigned.

For building models authored using Revit, the use of generic models and in-place

families shall be minimised. See Appendix C Part 1’s “Category” column for details.

Parameters shall be utilised for model management. For example, CAT code shall

be utilised to manage colour setting and search set creation to facilitate clash

detection and resolution.

In order to achieve AAHK-required LOD and standards, discipline models may be

authored using Revit and Civil 3D at the same time. For example:

Corridor models of bridge, tunnel, retaining wall, seawall, breakwater, pier, jetty

and the like shall first be created using Civil 3D, with detailed features further

modelled using Revit.

Marine mud layers, marine deposits, bollard, etc. shall align with Appendix C

Part 1 – BIM Matrix “1. Site Model” or add if needed.

Electrical-related element such as lighting, over-water airport ground lighting,

etc. shall align with Appendix C Part 1 – BIM Matrix “8. Electrical Model” or add

if needed.

2.2.5. Cross-Discipline Model Integration Using of Scripting and Automation

As AAHK projects are oftentimes interdisciplinary across multiple software

platforms, Design Consultants and Contractors are encouraged to use scripting to

automate modelling and interdisciplinary model conversions. To minimise graphic

and non-graphic data loss, Design Consultants and Contractors are encouraged

to explore and test data conversion methods using innovative approaches.

For example, Dynamo Studio may be used to batch convert Revit model elements

into Civil 3D. In the event Design Consultants use software other than Revit to

author Concept and Schematic design models, scripts may be used to convert the

models to Revit and audit the geometries as the result of the conversion.

Design Consultants and Contractors shall include project-specific diagrams in

Project-specific BIM Execution Plans showing interdisciplinary file exchange

strategy and workflow. The figure below shows an example of a BIM project utilising

Revit, Civil 3D, Navisworks, BIM 360 Glue, 2D AutoCAD, Rhinoceros and Tekla:

Particular Specification – Appendix J – Appendix D

2.3. AAHK-preferred Modelling Methodology

Design Consultants and Contractors shall further specify project-specific and

discipline-specific modelling methodology for every model element in their Project-

Specific BIM Execution Plan base on SOS and AAHK’s requirements. The creation

method for every element created in the BIM shall be clearly stated and the model

category shall be verified correctly (e.g. Category parameter in Revit), to further

ensure AAHK Asset fields are assigned to correct categories.

The following procedures and methodologies pertain to AAHK-preferred best

practices with minimum requirements. Project-specific and discipline-specific

approaches shall be further refined by Design Consultants or Contractors in

Project-Specific BIM Execution Plan for AAHK approval.

2.3.1. Dynamic Envelope

Dynamic envelope shall be used to:

Represent existing objects that do not require LOD beyond 100, but is necessary for design coordination and clash detection (for instance: zoning envelope, adjacent buildings);

Represent required clearance from design elements (for instance: 3D flight path and no-obstruction zone, headroom for stairs / ramps / access corridors);

Required clearance (e.g. setback or minimum distance) from existing or future structures (e.g. building setback envelopes, BHS system envelopes, APM access route envelopes);

Anticipated future elements that interfaces with the project (e.g. planned future building envelopes, planned trench location, planned sky bridge or tunnel connection location, anticipated reclaimed land surface).

Dynamic envelopes shall be created to show clearance for designed elements, or

creative dynamic envelopes for design reference based on survey data or existing

drawings/models, or link dynamic envelopes created by other interfaces which

have been reviewed by AAHK and distributed via collaboration site.

APPENDIX J

Contract T18W008 PS AJ D 8/56 (Addendum No.1) AA 07/12/18 Primary Sorter Replacement Works for Baggage Handling System

Particular Specification – Appendix J – Appendix D

Clashes between dynamic envelops and other design elements shall be flagged,

reviewed and resolved.

Working space or maintenance clearance should be specified in clash detection.

The clearance should be added to the model element as non-graphic information

and used for setting clearance when running clash detection.

2.3.2. Architecture and structural elements

In accordance with Section 2.2.3, overlapping of architectural and structural

elements shall be minimised for WIP models and completely eliminated for

deliverables.

In the event structural elements’ surface finishes (e.g. tiles, carpet) are specified

by architectural discipline, non-structural walls containing only the finish layer shall

be modelled, with no overlaps to structural walls. Exception is given to feature /

sculptural structural elements whose surface finishes are specified by architectural

discipline; a geometric duplicate may be hosted in architecture model to apply

finishes. Such architectural copy of structural element shall contain only finish

information with explicit indication in object names (e.g. Revit family name). No

duplicating non-graphic information shall exist between architectural and structural

models.

Typical structural columns shall span between finish floor levels with zero (0) offset

to ensure vertical structural continuity. Vertical structural elements’ continuity shall

be ensured; in the event the hierarchy is reversed, the “Switch Join Order”

command shall be used to rectify. For deliverables, other overlapping elements

shall be resolved via Cut Geometry or manually create openings. The figure below

shows the preferred hierarchy on the left (continuous vertical structural element).

Fall shall be modelled if structural top surfaces is sloped.

Floor and wall openings for Building Services elements shall be modelled in design

stage. For Structure models, rebar shall be modelled at critical connections. Re-

bars and joint details shall be modelled at critical locations to prove constructability

upon AAHK request during design stage.

2.3.3. Building Services

All ducts shall have correct type names specified based on use and corresponding

duct systems. Insulation should be added when applicable.

All pipes shall have correct type names specified based on use and corresponding

Level 2: Base Map, Linework, and Engineering Drawings

After the Civil 3D objects are setup in Level 1, base maps, linework and engineering

drawings can be developed in Level 2.

If the production of 2D drawings and Civil 3D modelling is developed under multi-

user environment, working parties shall refer to core project objects into composite

drawings. Furthermore, working parties shall keep the size of the drawing in

minimal size and ensure the core objects are not unintentionally modified. At the

same time, plan sets and production drawings can be prepared as required.

Level 3: 2D Drawing Sheets

After the relevant base map, linework and engineering drawings are developed,

2D drawing sheets can be ready to generate, e.g. tunnel layout plans, road profiles,

utility sheets and landscaping sheet.

To generate 2D drawing sheets, base drawing and other drawings shall be referred

using x-ref (AutoCAD external references).

4.1.5. External References and Linked Files

External references may include .dwg, .dgn, .rvt, .ifc, .dxf or other compatible

2D/3D file types operable by AAHK-preferred software. These links shall be

preserved in the process of file sharing and collaboration.

For Master Models, Reference Type shall be “Attachment” and Path Type shall be

“Relative.”

For Civil 3D master models or coordination models, data shortcut references shall

be maintained for alignments, pipe networks, pressure pipe networks, TIN

surfaces, and corridors.

4.1.6. Storing Viewpoints in BIM Files

The design, coordination and construction issues shall be flagged within

coordination models via saved views, and use the views for progress and

coordination meetings.

Saved views shall be grouped by dates and interfacing events/parties. In Autodesk

Navisworks, the groups shall be established by creating folders named

YYYYMMDD-[Name of Interfacing Event/Parties].

4.2. Model Size

4.2.1. Maximum Model Size

All models (except federated .nwd models) shall not exceed 150MB each.

Maximum size of federated .nwd models shall be project-specific as approved by

AAHK.

BIM files shall be kept at their minimum size. Items not appropriate for use or

irrelevant should be purged or detached periodically and prior to submission.

The models shall be divided by location, zones and/or disciplines, sub-disciplines,

according to strategies proposed in project-specific BIM Execution Plan, once

model sizes exceeds AAHK-mandated maximum.

4.2.2. Purging

BIM shall be purged of all unused views, families and other settings upon

submission.

4.3. Colour Scheme

For easy review and better collaboration in federated models, the colour specified

in Appendix C Part 1 - BIM Matrix shall be followed to assign colour for their models’

views.

The AAHK-specified colour shall be followed in different stages including but not

limited to work in progress (WIP), statutory submission, submission for AAHK’s

approval and final submission to AAHK’s assets and facility management teams

(including but not limited to TSD).

APPENDIX D TO

APPENDIX J

Contract T18W008 PS AJ D 38/56 (Addendum No.1) AA 07/12/18 Primary Sorter Replacement Works for Baggage Handling System

Particular Specification – Appendix J – Appendix D

AAHK-specified colour may be by model element or by system. By-system colour

requirements are typically applicable to underground utilities, plumbing or systems

that have both long-spanning conduits/pipes/wires and individual connection

model elements. See Appendix C Part 1 – BIM Matrix for details.

If key project-specific model elements or systems do not have AAHK-specified

colour in BIM Matrix, the colour scheme for these systems shall be assigned and

submitted for AAHK’s approval.

4.3.1. Colour Display Methodology

Colour shall be displayed via filter (Revit), appearance profiler (Navisworks) or

other parametric method to achieve appearance based on the CAT Code

parameter, rather than altering the materiality of model elements or systems.

In Revit, for instance, the model elements’ material colour shall not be manually

overridden in the “Appearance” tab. The colour shall remain the actual material

RGB (unless the element or system happens to be the same colour as CAT Code

colour in real life). Other properties such as thermal and physical attributes shall

also be correctly assigned to each material.

4.3.2. Mandatory Views to Apply Colour

Aside from federated models in coordination and interfacing software (e.g.

Navisworks), AAHK-specified colour shall be applied to:

Non-drafting interdisciplinary coordination views or layouts

Non-drafting inter-project coordination views or layouts

Non-drafting views or layouts showing more than one system (e.g. a

view/layout showing both fresh water and flush water pipe systems)

Matrix.

4.3.4. Existing / Context

Data source for the existing model shall be stated by:

a) Correct model file naming for individual existing model as stated in Section

5.1; and

b) Applying different % transparency if needed. For example,

- Data source from site survey: 30% transparency; and

- Data source from as-built record: 70% transparency.

5.1.7. Model Naming Examples:

For project 9999 (a passenger concourse T2 building project) done by the Author

MNO, the BIM models are divided by levels (L3/L5/L6):

5.2. Workset Naming

Workset is Revit's way of allowing multiple team members to work on the same

project. The Worksets of the projects shall be created and maintained.

Do not unload a linked Revit file and not synchronise with Central (use

Visibility/Graphics or opened=No).

Do not use Worksets such as layers. Small projects can be accomplished with

the two default Worksets.

The two factors determining the number of Worksets are scale of the project

and the number of people working on the project.

Do not create Worksets for annotation or notes.

For new content created within an existing AAHK base model, separate

Worksets shall be created to allow for definition and separation of new content

from existing.

Sub-disciplines, such as interior furniture, light fixtures, landscape and

signage are to have individual files instead of Worksets within architecture

BIM.
