The new system in the proposed addition includes a complete working plans of the sprinkler system and 5 of 7

6 hydraulic calculations per NFPA 13 standards. The new system is assumed to be located in conditioned spaces and cost for a dry system have not been included. No work or modifications to the existing fire protection system has been included as part of this cost estimate It is has been stated by the school district that the existing fire protection entrance, cistern, and pump have been designed to provide adequate supply to the fire protection system in the new addition. This cost estimate does not include any additional costs should this be determined at a later point in time to not be accurate New Addition building mechanical scope of work is generally understood to include the following: Hydronic heating will be provided from the existing boiler and a new pair of base mounted circulation pumps located in the existing boiler room. New heat piping and pipe insulation from the addition back to the existing boiler room is included. Ventilation for new spaces will be provided by a roof top mounted energy recovery ventilator. Ductwork, duct insulation, registers, grills, and fire dampers are included as required. Air conditioning is not included for any spaces. Domestic hot/cold water piping type L copper and pipe insulation will be provided off the existing system. New fixtures in the locker rooms and public restrooms will include standard low-flow features to minimize water consumption. Cast iron sanitary waste piping will exit the back of the addition and connect to the existing septic tank located outside the foot print of the existing boiler room. New floor drains are included. It is our understanding that that waste volume for the total building will remain unchanged and therefore we have not allocated any costs for upgrades to the existing septic treatment system. Roof drains will be provided on the flat roof sections of the addition and will exit the southern end of building. Division 16 Electrical Nine (9) area/roadway site lights have been included as Lumark RV LED Ridgeview shoebox style fixtures mounted on concrete light pole bases All power wiring for the new addition will be fed from a centrally located subpanel in the addition which will be powered from a spare circuit in an existing main panel located in the existing utility room. It is our understanding that the current electrical service has capacity to meet the electrical loads anticipated in the new addition based on a cursory review of available electrical capacity by the project electrical engineer Lighting fixtures will be provided for all new spaces and will include a mix of high efficiency, institutional grade, direct and in-direct fixtures controlled from standard wall switches. Multiple ballast switching (from wall switches) is included in the music room to provide added lighting control during performances. Costs for a lighting control system, theatrical lighting system, occupancy sensing systems, or daylight harvesting systems have not been included. 6 of 7
