1 Steel reinforcement and BIM The CELSA Group TM approach

2 Products: cut and bend reinforcement, carpets, cages, couplers, accesories. Services: fixing, just-intime, express delivery, 3D-modeling, digital information. Locations: Denmark, Sweden, Norway, Finland, UK and Spain.

3 our role in the BIM Definition of BIM BIM = New tools and new processes Preconditions for implementation of new tools and new process Measurements of the existing and new process (to prove improvements and make correct decisions) Long term collaboration between affected actors (to create conditions for continuous improvements)

4 the measurements Construction company x2 Designer Celsa Steel Service

5 Problems Solutions Problems Solutions Celsa Group TM current situation Engineering companies Contractor Steel quantities are a key but difficult to determine in 2D. 3D is the solution but Software is expensive Few knowledgeable people Workload is variable: difficult to cover picks. Estimated quantities based on basic detailing. 2D teams outsourced paid per hours. Do not accept penalties for errors in quantities Low price in the contract Projects are not detailed enough Higher requirements regarding documentation Revise engineering (usually another engineering company) Try to modify the project and reduce the cost Push the pressure to the suppliers and subcontractors

10 QR overview

11 implementation status -Visual control - Identification of SWP - Create models - Communication with customers, designers, production - Generation of specification lists - Generation of drawings (assembly instructions to production) - Integrate with SAP - Multiuser models - Educated users Tekla Structures - Possible to integrate with ERP-system - Good references (Strängbetong, SWECO, WSP, NCC Teknik, Skanska) - Worldwide corporation -Increase efficiency - Increase sales of SWP - Evaluation Project types - Infrastructure - Office and residential - Foundation -..

13 the challenge It s a very complex construction and it s very hard to identify and specify possible welded elements There s a high risk of errors if I ll try to do it //Celsa Swedens most experienced technician

14 redesign Suggested a new way of form building Several meetings with designers and Trafikverket Discussion with production personnel

21 results and challenges Customer wishes highest degree of prefabrication possible Prefabrication degree +80% possible (SWP, SpinMaster) Increased demand of supplier knowledge Increased communication between designer, supplier (celsa) and contractor Less focus on price More focus on reinforcement solution More time consuming administration Increased communication with production Increased time needed for planning and specification

22 Value proposition Engineering companies 3D REBAR DETAILER ON DEMAND Contractors WE WILL FIND THE MONEY FOR YOU More realistic quantities. Provide 3D modelling capabilities in- or out-house to cover your picks. Better projects delivered to the client (quantities, details, etc). Redesign some details to reduce quantities. Come up with solutions to reduce installation time. Provide 3D modelling capabilities in- or out-house to cover your picks.
