PART 3 - EXECUTION

3.1 Equipment Arrangements: Since equipment of equal capacity is not necessarily of same arrangement, sizeor construction, the Contract Documents are prepared on basis of one manufacturer as "designequipment", even though other manufacturers' names are mentioned. If contractor elects to useequipment other than "design equipment" which differs in arrangement and size: submit detailed

drawings, indicating proposed installation of equipment. Show maintenance clearances service removalspace required, and other pertinent revisions to the design arrangement. Make required changes in theWork of other trades, at no increase in contract. If required, provide larger motors, and equipment,additional control devices, valves, fittings and other miscellaneous equipment required for properoperation, and assume responsibility for proper location of roughing and connections by other trades. Ifrevised arrangement submittal is rejected, revise and resubmit, or submit specified item which conforms

to Contract Documents.



3.2 Trade Coordination: Install Work only after coordination with other trades. In general, each trade shall

coordinate and route its Work as close to ceiling deck as possible to permit: Ceiling heights as called for. Location of exposed or finish elements as shown on architectural reflected ceiling plans. Access to servicepoints. Crossing of piping, ductwork and conduits. Convenient removal of at least one 2' x 4' ceiling tilewithin each space or every 200 square feet of area for access to above ceiling components.

Coordination and Work required to accomplish above shall be provided as part of the contract Work with

no additional cost to the owner. Work to include: Offset of piping, ductwork and conduits as required(between rooms). Routing changes within rooms or spaces to avoid conflicts.

3.3 Substitutions: Refer to Supplementary General Conditions. The design equipment called for is therequired standard of quality and function. If contractor desires to bid on another kind, type, brand, ormanufacturer of material or equipment other than those named in specifications; submit complete

information in detailed tabulated form, comparing (item-for-item)material or equipment offered withdesign material or equipment. Include sufficient information to permit quick and thorough comparison,and include performance curves on same basis, capacities, power requirements, controls, materials, metalgauges, finishes, dimensions and weights of major parts.
