Value and risk management - Assignment ExampleDundee compass has its substructure done as aggregate and isolated foundations but no permanency of the ice narration. As a result the concrete used is more in order to carry the weight of the ice floor.II. The frame work for Skydome arena is 9.4% of total cost and at 176.44 per m2 compared to 9% of Dundee Arena and 73.2 per m2. This gives a difference of 7.6% i.e. 103.24 per m2. The two arenas both adopt steel frames for the construction. The difference in cost per m2 has resulted from the large roof being constructed and which lacks intermediate columns. These types of roof spans are quite expensive to put up. The span for Skydome arena is therefore in excess of 60m as a result requiring more quantities of steel in the roof trusses. Therefore the basic estimate of 80kg per m2 of the gross floor area is projected. The amount of steel applied in Dundee arena is less kilograms per metre squared. This is highly unlikely to jeopardize th e quality of the stadium. However, adjustment can be made as necessary bearing in mind the total weight of the whole arena. The 80kg steel per m2 can be reduced to 60kg per m2 or however less if intermediate columns are used instead for support.III. The Roofing is 8.6% for Skydome arena at 161.46 per m2 as compared to 3% for Dundee Arena at 22.5 per m2. An overestimate of 5.4% on roof at 139 per m2 is determined here. The roofing material and structure has deployed very expensive methods and materials. The roof for Skydome is intended to have partial composite construction with mastic pave for the plant area and clad with profiled metal decks on purlins. For the insulation a PVC single-ply membrane and a vapor barrier is adopted plus a plywood base. All these materials are very expensive and should be substituted with cheaper materials while maintaining quality of the roof structure. Dundee arena has adopted steel plates and metal cladding other(a) than plywood and vapor barrier. IV.
