Using Building Information Modelling from the start of a project can result in significant cost savings in the long run

veryone working in arena development will agree that ‘content is king’. That is where you get your turnover from and that is what determines success or otherwise in your income statement. Arena development would not work without cost management and it is essential to see the bigger picture to achieve a successful project. But does that mean that everything else in an arena project is a lower priority? It is important to establish financial boundaries from the start and to obtain the information and data to ensure tight cost control. The 2011 World Handball Building Information Modelling (BIM) is the Championships in Sweden will be process of generating and managing building staged at a number of new venues data during its lifecycle.

geometry, spatial relationships, geographic information and quantities and properties of building components. Today, when there is such great focus on finances in building projects, more and more clients are demanding 3-5D planning/BIM from the outset, where 3 is the model, 4 is the timetable and 5 is the calculation. The full benefits of BIMs can be realised, if architects, structural designers, other consultants and contractors cooperate in using the building information models. This requires an open mind, experienced guidance and the appropriate software tools. Working with BIM gives you 20-25% more information on which to base decisions and if used properly this can reduce costs by 15-20%. There are those who argue that this is a more expensive way of working, and perhaps it is initially, but over the course of a project there will be significant savings.

Building contractors are constantly under pressure to compete on price and they are constantly looking for ways to keep costs in check. For this reason, many construction companies are using 3-5D planning (BIM) in project planning.
Prior to the 2011 World Handball Championships, which will be held in Sweden, a number of new arenas have been built to accommodate between 3,000 and 12,000 spectators, and some of these have been planned using BIM. The 4,700-capacity Kristianstad Arena was using BIM as early as 2006 and emphasis was placed on having the right information right from the start of the project and keeping a tight grip on finances throughout the project. The advantages became evident when consultants analysed the cost estimates and compared various scenarios using a so-called ‘Clash Control’. As a result, they were able to avoid cable runs going through ventilating pipes, tube drawings through roof trusses, etc. The precision of the cost estimate meant drawing errors never became production errors. Following this positive experiences of BIM planning, the system was also used for the contract procurement exercise. The cost of erecting and equipping the arena was estimated at E35 million. The contract procurement exercise suggested that the construction of the arena could be E4 million cheaper using BIM, and the focus of the project was on optimising production, where the BIM planning was an important element in keeping costs down. The arena was opened on 15 October and the final forecast is estimating end costs around E6 million (17%) lower than the original cost estimates. The success of this project also means that the venue’s operating costs will be reduced from approximately E3.5 million per year to just over E3 million. Sweden-based arena specialist ArenaProjekt recognised the advantages of using BIM earlier than most and employed it to generate confidence and security around projects. For almost five years, the company has successfully used Clash Controls, 3D and 5D, leaving the 4D level to the building companies, as this area is more relevant to the actual building process. The projects ArenaProjekt has carried out using the BIM have proved beyond doubt that this is a business model that can have a very positive effect on controlling costs in the construction of all types of venues. n www.arenaprojekt.com
