  2. Industrialisation through designHow the principles of industrialisation works in our projects Projects using in-house developed production systems Other projects Integrated activities Rules IP Components Defined client Platform Coding system Exchange One off Architect competition Non defined client Conglomerate of previously used solutions OWOW 2010-10-13 / Carl Jonsson

  3. Main topics Setup of a production system Important elements in the design process Examples 2010-10-13 / Carl Jonsson

  4. Main topics Setup of a production system Important elements in the design process Examples • Requirement handling • Platform • Process • Compliance verification • Cooperation agreements • Supply chain • Manual 2010-10-13 / Carl Jonsson

  5. Setup of platform for multi family housing M U L T I • 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) M2-1 Nordic Current M2 harmonized Finalized products implemented M2-2 M2-2 Nordic Raised floor ? M2-1 M2-3 M2-3 Nordic New platform based on req from other values 2010-10-13 / Carl Jonsson

  6. Requirement handling 2. Express each requirement or group of requirements to one or more properties 1. Collect requirements 3. Transpose property requirements to appropriate parts of production system • RDN requirements • CS requirements • Building codes • Efficiency (cost, speed, labor) • Aesthetics • Industrialization • Universal design & Geometry • Robustness, rigidity, durability • Acoustics • Fire • Hygiene, health, environment • Energy efficiency • Safety in use • Sustainability • Platform • Components • IP Intermittent flow of new requirements Do the attributes fulfil the requirements? • Orientation • Scope • Prerequisits • Goals • … Development deliverables Yes No 5. Check • Platform • Components • IP 7. Develop (process detailed separately) 6. Create Project Plan 4. Express production system attributes 2010-10-13 / Carl Jonsson

  7. Attributes Requirements Requirement handling based on consumer insight 2010-10-13 / Carl Jonsson

  8. 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. 20 Levelling screed HCS 37 220 Massive, HCS 27 or Compressed HCS 37 • 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 2010-10-13 / Carl Jonsson

  9. 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 Things that will be updated in version 2.0; • 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 2010-10-13 / Carl Jonsson

  10. 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). 2010-10-13 / Carl Jonsson
