We have all seen McMansions, they have one thing in common–they focus all of the quality on the front of the building with brick or stone or gables or arched windows. Meanwhile the sides and rear are completely devoid of character (quality) and so become bland vinyl-clad sides of a box that are truly ugly. But here is the motivator behind this: the decrease in quality allows the McMansion to increase in size. This happens in the interior, too. The volume of one big open room can seem impressive, but where are the cozy spaces for intimate conversations? Where can you get away to relax and read a book? Do you want everyone who is come for a holiday dinner to see all the dirty dishes used to prepare the meal? Is there a smart, discrete place for the powder room? At first glance, the larger home at the same price seems to be an excellent value, but there are things to consider when sacrificing other elements of a home for size. These show up in many, many ways including: Enjoyment of Your Home, Resale Value, bigger does not mean more value, Maintenance, Energy Bills
The payment arrangements adopted on a contract directly affects the level of risk borne by the contractor. Where the contract is let on the basis of a drawings and specification lump sum the contractor assumes the risk for both the quantity and pricing. In lump sum contacts based on bills of quantities and remeasurement contracts the contractor assumes the risk for the pricing only. With reimbursement contracts the client assumes the risk for the quantity and pricing. The payment arrangement, therefore, directly motivates the contractors efforts to carry out the work in an efficient and economic manner. This in turn has a major impact on the final price paid by the client.
In general it can be said that larger buildings with simple, rectangular, regular floor plans and elevations will be less expensive per sq.m. of floor area than smaller, complex shaped, curved or angular buildings. Economies of scale apportion fixed overheads to a larger extent of productive space. Simple setting out and buildable solutions encourage greater plant use and generate higher productivity and less waste. Complex layouts and details are slower to assemble and may involve a number of trades with a consequent greater risk of mistakes and defects. The degree of compartmentation and repetition will also affect the overall cost of the work. New building work is considerably cheaper than work of a repairing nature or work in existing buildings. Single storey structures tend to be more costly than buildings up to three storeys high, beyond which point they become progressively more expensive.
The clients attitude towards initial versus the whole life cost of the building can significantly influence the specification. Buildings incur costs over their life time; these include initial capital costs, operating costs, maintenance, disposal and finance costs. The key decision is whether to spend more money initially on better alternatives in order to save money in maintaining and operating the facility
