5 <br />• One (1) 25-ton unit serves a changeover variable air volume system, which will be modernized with <br />a new sequence of operation and controls. Small electric wall heaters will be added in 2 locations <br />and interlocked with the cooling system. <br />• The A/E team will coordinate with Snohomish County PUD to maximize conservation grant funding. <br />However, at this time no energy auditing or energy modeling is required. <br />• Scope will include independent test and balance, and commissioning. <br />• The library will remain open during design and construction. The A/E team will participate in <br />developing the construction sequencing and schedule. <br />C. Project Schedule <br />The proposed project schedule is as follows. Note - all three parts of this project will run concurrently: <br />• 30% Design 3 months <br />• Permit Design 3 months <br />• 90% Design 3 months <br />• Bid 2 months <br />• Build 3 months <br />D. MACC <br />The estimated Maximum Allowable Construction Cost (MACC) is: <br />• $2,500,000 -This includes all materials, equipment, and labor. <br />1.4 PROJECT 2 – SOUTH PRECINCT <br />A. South Precinct Objective <br />The City of Everett intends to replace the existing DDC systems serving the South Precinct to reduce <br />system energy use, increase system reliability, and improve occupant health and comfort. The project <br />scope includes the replacement of the existing DDC system with connected wireless thermostats and <br />controls, along with installing heat in the VAV boxes on the first-floor east perimeter. The design will <br />include a review of system sizing based on revised building occupancy and use and review of the <br />variable air volume zone controls. Additional scope may include the design of necessary electrical and <br />structural modifications and any noise or architectural screening if required. <br />B. Project Description <br />• Replacement of the existing DDC system. BACNET IP with Niagara 4 front end. Per the City of <br />Everett Resource Conservation Program specifications. Include the following alternates in the <br />design that may be removed from the project based on pricing. <br /> I. Demand control ventilation at zone level. <br /> II. Occupancy sensing at zone level for standby setback <br />• Replacement of the existing VAV boxes with FP VAV boxes with electric heat on the first-floor east <br />perimeter. The following zones are affected, Zones: TU-1, TU-3, TU-4, TU-5, and TU-6
