1 Construction automation and productivity - Industry perspective Vice President R&D, Ilkka Romo Skanska Oy Ilkka Romo

2 Skanska in short One of the world s leading companies in construction and project development International business since 1897 Four business streams 4,000 repeat customers Revenues totaled EUR 13 billion in ,000 employees Ilkka Romo

3 Local presence global strength USA Norway Finland Denmark Estonia Sweden United Kingdom Poland Czech Republic Slovakia Romania Hungary Colombia Venezuela Peru Chile Argentina Brazil Revenue by geographic areas Nordic Countries 47% Rest of Europe 24% America 29% Ilkka Romo

4 Where to focus? Building construction Building material industry Civil construction Biggest improvements needed in: Building construction Concrete based production Lot of different explanations: Increased requirements and quality Ilkka Romo Lähde: VTT tuottavuuskatsaus 2005

5 We have 125 years of experience 1887 R.F. Berg founded Skånska Cementgjuteriet AB 1897 First international order to the U.K First Commercial Property Developme nt project in Malmö, Sweden 1965 Noted at the Stockholm exchange 1971 First contract in the US: the undergroun d station 63rd Street in NYC 1982 First acquisition in the US 1984 The name Skanska is used internationally 1994 Skanska Finland founded Tripled size: Acquisitions in the Nordics, Great Britain, Central Europe and Latin America Ilkka Romo

8 Productivity in practice at sites Production 30% Waiting 40% 30% Transfer Huge potential! Ilkka Romo

9 Reasons for reduced productivity Wasted materials Re-work Warranty works Accidents Re-planning Management / problem solving Interruptions in production Storage problems Lower production capacity Delivery problems Visible Invisible Real productivity leaks To increase productivity we have to first identify the root causes Ilkka Romo

10 What have we done in Skanska? Process development Lean construction Standardization Prefabrication development Logistics development Safety development. AND BIM! Ilkka Romo

11 Residential design platforms Ilkka Romo

12 Industrialized production Ilkka Romo

14 VMI Store 1. Log in 2. Read the barcode 3. Confirm your purchase 4. Log out VMI stands for Vendor-Managed Inventory -Small items can be purchased easily at site which saves production time. - Projects are invoiced monthly based on the consumption. - Consumption control is based on read barcodes and minimum quantities set for each - Supplier refills shelves when minimum quantities are reached Ilkka Romo

15 Just in Time deliveries through terminal in framework phase Materials that will be lifted to the stories in structural phase are delivered through logistics terminal where storey specific materials are combined into truckloads and delivered to site in accurate time. Materials are lifted directly from the truck to the storeys Ilkka Romo

16 Safety Ilkka Romo

17 BIM Building Information Modeling - Building Information Management Ilkka Romo

18 BIM Building Information Model and Building Information Management (or VDC..) 2D drawings Reports BIM Model Information of components and spaces Identification Quantities Spaces Materials Locations Properties Required in IFC and native formats! Ilkka Romo

19 BIM improves design quality BIM based design coordination reduces errors and improves collaboration among the design team Constructability analyses MEP equipments coordination Reservations for piping Tracking down missing or wrongsized openings Model checking and clash detection is an essential part of the design process Solibri Model Checker tool based on the IFC standard As Oy Helsingin Esmeralda Ilkka Romo

20 With BIM information is available

21 Digital information and automation in civil works Ilkka Romo

22 Machine Guidance Civil Construction Skanska Norway Advantages with machine guidance: Increased productivity Fewer production errors Less dependent on the surveyor Graders (3 systems) Tunnel drilling rig (10 systems) Digital construction data Sea vessels (3 systems) Dozers (8-10 systems) Asphalt paving (1 system) Excavators (40-50 systems)

23 Production model Prefabrication information Site planning and safety Supply chain management, Logistics Drawings, Reports, measurements, coordinations, Purchase packages Details: ARC, Structural, MEP Scheduling (4D) Ilkka Romo

24 Logistical planning - lifting plan Ilkka Romo

25 Prefabricated Concrete Ilkka Romo

26 We have BIM tools available, but Ilkka Romo

27 Key to the productivity is: Ilkka Romo

28 Integrated utilization of digital information Ilkka Romo

29 What information is needed in a construction project? 1. BIM-based information flow through project phases and between participants 2. Procedures and tools for contractors and suppliers to integrate product and production data into this flow 3. Take a full advantage of new tools re-engineering Handover processes Requirements System design Generic materials and products BIMCON project in RYM PRE -program Concept design Design Procurement Manufacturing Construction Quantity take-off Scheduling 4D Procurement systems Cost management As-built data Construction and supply status Logistics management Supplier ERP Detailing Product selection Product databases Supplier design libraries Page Ilkka Romo

30 Information management Ilkka Romo

31 Information to the sites: mobile devices Site mobilization Drawings and documentation, instructions Punch lists, quality control Light BIM models (IFC) Status follow- up / control Connections to the back-office systems More and more mobile applications coming Cloud technology SITE MOBILIZATION BOOM HAS STARTED! FUTURE IS PAPERLESS, THE TECHNOLOGY ALREADY EXISTS! Ilkka Romo

32 Future? Portable/wearable computers Ilkka Romo

33 Can we improve? Empire State Building, 102 floors, 13 months Chinese 30-strorey hotel in 15 days Residential building in UK - 10 days Plans in Changsha: 220-storey Sky City in 90 days YES; WE CAN Good planning, prefabrication, flawless design, logistics, BIM remembering safety and quality! Ilkka Romo
