A Design by promoter or a consultant

The whole of the design, including all drawings and specifications, is completed before construction tenders are sought - except for drawings not needed for tendering purposes, such as for concrete reinforcement.

A promoter may have sufficient staff to undertake design work 'in house' or he may put all design out to a consultant, or divide the design work between them.

On schemes involving different types of engineering, design may be let out in separate 'packages' to different specialist consultants. For instance the design of an industrial estate may be packaged into - roads and drainage; water supply and sewerage; power supplies, and landscaping. For large schemes the promoter may appoint an overall consultant with wide experience to co-ordinate the inputs of the specialist design consultants.

Some elements of design may be left for the construction contractor or his sub-contractors to undertake, such as the design of heating and ventilating systems, or the cladding for a building. Specialist suppliers may need to design their product or services to suit the project. Advantages are:

• The promoter can check all aspects of the design to ensure they meet his requirements before construction starts.

• Competitive tenders for construction are obtained on a clearly defined basis encouraging construction contractors to submit lowest prices.

• The risk of having to make alterations to the work during construction is minimized, giving a better chance of the project cost not exceeding the tendered price.

• The promoter is not committed to proceed with construction until he sees tendered prices and accepts a tender.
