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