1.3 RESPONSIBILITES The body or bodies employed are directly responsible for the design, supply, manufacture,

delivery, storage, installation, setting to work and commissioning the complete building services systems as required under the project. The Performance Specifications provide the basis of the Employer's Requirements permitting the Contractor (also implies his appointed Sub-Contractors) to develop the design and design drawings for approval prior to installation. The design drawings shall indicate size and provide accurate location of all builder's work requirements, including weights and sizes of all plant and equipment, size and location of all bases, plinths and size and type of any cast in fixings required. The Contractor shall mark up drawings, mark on site or provide templates as appropriate detailing the requirements.

The Performance Specifications may be supported with tender drawings which describe the

main plant and distribution philosophy for the building. If so, the Contractor shall develop the final detailed design using the main plant and distribution philosophy developed. Unless there is a change to the rationale already designed it is not intended that the detail of the main plant should require to be altered. The design parameters of the final design shall be used to verify the detail of the distribution scheme however.

The Contractors shall develop detailed design utilising the relevant Performance

Specification(s) associated with their works. The final detailed design will entail the preparations of all calculations covering the services

systems. Copies of all calculations will be submitted to the employer for comment. Installation working drawings will be developed for all systems through the production of
