Our work in action: The Monument Building
Through BIM we have been able to deliver measurable cost and time savings for the client. A complex 10-storey commercial development in a high profile location, Skanska has employed a full-time BIM Manager to oversee the implementation of best practice BIM techniques, leading to fantastic results.
We provided our steelwork subcontractor with an accurate model on which to base the steelwork designs. The ability to provide such highly sophisticated models had not previously been possible due to software incompatibility. Working with the BIM model proved to be much faster and reduced the opportunity for human error. The highly accurate designs translated into accurate construction, with only 0.5% spent on variations – an excellent result on such a complex build.
Further savings are made through coordinated temporary protection design. A review of the model revealed 81 instances where the position of cladding brackets on temporary edge protection would clash with cast concrete posts. This equated to 11.5% of the total number of brackets on the project. These clashes, which were not evident in the 2D drawings, could be designed out before construction began, realising significant cost and time savings.
Reduced requirement for diamond drilling
Skanska’s building and engineering teams collaborated in the design phase to identify where access, services and utilities holes could be incorporated into the precast concrete. This reduced the need for personnel to work onsite with diamond drills, leading to time and cost savings while also providing a safer working environment.
More than a hundred hard and soft clashes between services and the main structure were cost-effectively resolved at the design stage. This included a significant clash between our concrete works and an adjacent building’s party wall, which was not evident in the 2D drawings but was identified once laser scans of the site were incorporated in the model. If not caught in the design phase, this single clash could have delayed the schedule.
