Setup of platform for multi family housing

New platform based on req from other values

• Three platforms that can be used on a Nordic level• Each platform optimized for specific values• Skanska’s production system for multi less sensitive to

market situation (suppliers, factories, internal resources)

• The three platforms can be used to control and benchmark both the suppliers’ and our own efficiency

• Increased focus to continuously improve production system, initially phases 2 and 3 of IP.

• Measures taken to establish processes with prioritized suppliers (IPN, Skanska Installation)

Requirement handling

• Efficiency (cost, speed, labor)• Aesthetics• Industrialization• Universal design & Geometry• Robustness, rigidity, durability• Acoustics• Fire• Hygiene, health, environment• Energy efficiency• Safety in use• Sustainability

2. Express each requirement or group of requirements to one or more properties

1. Collect requirements

• RDN requirements• CS requirements• Building codes

• Platform• Components

• IP

3. Transpose property requirements to appropriate parts of production system

6. Create Project Plan

Development deliverables

• Orientation• Scope• Prerequisits• Goals• …

7. Develop (process detailed separately)

4. Express production system attributes

Do the attributes fulfil the requirements?

• Platform• Components

• IP

No Yes

5. Check

Intermittent flow of new requirements

Requirement handling based on consumer insight


M2-1− Same as version 1.0 except what is brought up in this presentation

− Slab equals current Finnish solution with some modifications to it in order to work in Sweden and Norway

− Close to the current platform regarding interfaces, performance, assembly order etc. Issues that needs to be checked have been identified.

– Modifications concern both RDN requirement and production methods;

– Room heights 2.60m with 2.40m in hallway– Lack of equipment at suppliers in SE and NO– Electricity in the vicinity of electrical cupboard

M2-1

− Platform Manual− Balcony connection details− Partition walls− Reference building− Building specification− Schedule of room finishes and external colour

scheme− Bathrooms and saunas− Roofs and terraces− Façade details− Slab details− Build up of terraced apartment floor− Soft joints in facade

− Doors− Railings for balconies, terraces and stairs− Substructure, garage, foundations− MEP specification: electricity,

communication and automation systems− MEP specification: air treatment system− MEP specification: plumbing and heating

system− Plant rooms− Fan rooms− Plumbing shaft− Ventilation distribution system in building

and in apartment− Electrical subcentral

Things that will be updated in version 2.0;


M2-2− Raised floor

− General platform properties;− build up of floor with measurements− ventilation distribution system incl kitchen− air inlets, interior partitions and apartment partitions− electrical distribution− bathroom, balcony and stairway interfaces etc.

− The raised floor height is 200mm (185mm from HCS to top of particle board).

− The interior partitions will be put on top of the raised floor.

− Apartment partition walls shall be in concrete as a general rule. Deviations may occur in special cases like ground floor.

− A load-bearing “gable wall” will be proposed as a new platform solution (valid for both M2-1 and M2-2).

Reference Building

− Currently a Revit model showing a possible configuration for multi projects for IP phases 2 and 3.


Reference Building

− Intentions for having a Reference Building;− To use it to show the contents of the multi platform, good examples of placing bathrooms,

kitchen, shafts, layout of structure etc− To use it to show what we expect is carried out in the Revit model in phases 2 and 3

respectively− To show CAD drawing techniques like grid system, conventions, areas, measurements and

similar− To use it in estimates and production simulations− To use it in energy simulations− To use it in training, e.g. technical / BIM / procurement

and similar workshops


Content of IP phases- IP phase 2

- Quantified objects- Basic measurements- Locked layout


Content of IP phases- IP phase 3

- Increased level of detailing- Correlation to shop drawings
