V. EXTENT OF WORK A. GENERAL 1. THE CURRENT CONDITIONS OF THE FACILITIES ARE DESCRIBED AS FOLLOWS: a. The two-story L-shaped Dormitory Buildings 3 and 4 are almost identical except for their physical orientations. Each floor consists of two dorm sleeping wings adjoining a center core where the lobby, lounges, laundry, mechanical room, etc., are located. The existing HVAC in both Buildings are split system heat pumps with 15 KW supplemental heats. The supply air in the sleeping wings is ducted and routed in a furred out drywall bulkhead along the room side of the corridor walls. Supply air registers are mounted on the vertical face of the drywall bulkheads and return grills are installed on the bottom of the same bulkhead. The return air is designed as a plenum system and is not ducted. The return air that enters the bulkhead flows through an opening with fire dampers into the air corridor ceiling plenum. It then flows through a series of wall openings and ducts prior to arriving to the air handler in the mechanical room. The current condition of the air distribution system in the mechanical room is very congested. b. The dryer system is inadequate and not functioning. The dryers are vented by means of 4 inch exhaust piping which run through a wall and intersect into a chase that runs vertically 30 feet to the roof. c. The center core of the building is serviced by a 7.5 ton split system. The system is providing adequate service but the supply registers are manufactured with volume control that students and staff can adjust. d. The last bedroom at the end of each sleeping wing contains two exterior block walls. These walls are un-insulated and exposed to the elements. 2. DEFICIENCIES AND CORRECTIVE ACTION a. RETURN AIR PLENUMS There are 8 total sleeping wings between both buildings. Each sleeping wing should be spilt into 2 zones. The air distribution supply of the current system is ducted and zoned however the return air is handled thought a common plenum for both zones. The current design causes deficiencies in temperature, air quality and balancing resulting in unsatisfactory air conditions. The air distribution system in the mechanical room is restricted due to its location and lack of space. b. The existing return air corridor plenum (located above the ceiling) is approximately 5.4 feet wide by 72 feet long and 18 inches high. This existing plenum is constructed of 5/8 inch drywall and metal studs. Demolition and removal of the existing ceiling assembly is required. During the demolition and removal of ceiling debris, the contractor must take all necessary precautions to be as clean as possible because the dormitory will be occupied throughout the construction. The entire building is to remain habitable at all times. The contractor must leave the premises clean daily so as not to disrupt the center operations. c. Prior to demolition, the contractor shall remove all electrical fixtures, fire alarm devices, etc. and temporarily reinstall so that the building is completely safe and protected from fire during the installation of the new ceiling plenum. All systems are to remain operable and functional during the construction period. The entire building is to remain habitable at all times. (Any damaged, broken, or defective fixtures or devices shall be immediately reported to the center.) d. The contractor is to construct two separate return air plenums, approximately ________ each, for each of the two required return air zones. The plenum divider wall assembly shall be constructed utilizing a one hour fire rated shaft wall UL U469 (or approved equal). The corridor ceiling/plenum assembly (horizontal shaft wall assembly) shall be similar to the shaft wall UL U469 (or approved equal) with a single layer of 5/8" fire code type "X" drywall attached to the finished ceiling side (Test No. WHI-495 PSH 0154/0167). The finished surfaces and installation of the fixtures shall be performed to match the pre-construction existing conditions. All piping and electrical conduit penetrating the divider shall be sealed with UL listed fire resistant caulk. e. Install 12 inches by 12 inches access panels at each water valve located in the plenum that controls the water flow to each room. Contractor is to verify that the existing plumbing access panels are fire labeled and can be re-used. In the event that the panels are not fire labeled or are damaged, the contractor must install new access panels that comply with code. The panels shall be locked, keyed alike, and installed in proximity to the valves that they serve. f. After the installation of the new ceiling assembly, the contractor is to re-install all fixtures and devices that are affected by the construction. The ceilings shall be finished primed and painted with 2 coats of latex paint with a standard color selected by the center. g. The Contractor shall have the fire alarm system tested and re-certified by the company currently holding the certification for the entire system. h. The supply ducts (approximately 8 existing) from the mechanical rooms currently routed through the janitor closets, entering the bulkhead supplying the bedrooms across the corridors, are to be removed. The new replacement supply ducts shall be re-routed through the mechanical room walls into the Laundry Room. From the Laundry Room extend to the point of connection where the existing plenum was previously removed. Every wall penetrated by the supply and return ducts shall have fire dampers installed. Fur out all ceilings where new ductwork is exposed. i. The existing 16 inch x 24 inch return air ducts routed through the janitor closets and pulling from the old return air system shall now be connected to one of the new return air plenums and connected to Air Handler Unit No. 1. From Air Handler Unit No. 2, eight existing 16 inch x 24 inch return ducts shall be connected across the corridors to the second new air plenum over the corridors. The existing Outside Air ducts located in the mechanical rooms shall be separated and connected to Air Handler Unit No. 1 and Air Handler Unit No. 2 respectively. j. Install a volume damper at the Outside Air entry of the plenum. k. All newly installed supply and return ducting shall be internally lined with 1½ inch insulation. l. All joints and seams are to be sealed with UL 181 approved duct sealant. m. All duct mounted return air temperature sensors shall be relocated and installed in the return ducts in the janitor closets. 3. DRYER EXHAUST VENTING DEFICIENCES a. Replace the 4 inch pipes in the Mechanical Rooms that are connected to the dryer vents. In each building, install an electric vent motor and a modulating fan control in the mechanical room of each building and pipe into the existing chases. b. Replace the existing registers in the building core area with a perforated style diffuser with an intergraded volume damper. c. The two-bed handicapped bedrooms adjacent to the stairs at the end of each dorm wing (rooms A18, B18, A28, and B28 of Building No. 3 and rooms C18, D18, C28, and D28 of Building No. 4) have two exterior concrete masonry walls that require additional insulation. Furring out existing walls with pressure treated 1 x pressure treated wood weather strips or steel channels at 16 inches on center. Between the furring strips install 1 inch thick insulation with an R factor of 5 or greater that complies with IBC/IRC requirements. Finish the walls with ½ inch drywall and paint with a primer coat and two coats of latex paint matching the room's interior walls. The windows in these rooms shall be finished with new trim, jambs, and heads to match the existing windows throughout the building. The built in desks shall have trim installed painted to match the walls, where affected. d. The contractor shall provide a test and balance report at the completion of the work. Perform testing and balancing of the existing HVAC system, including the air distribution in Buildings 3 and 4. The test data shall be complete and must include actual air flow (supply, return and exhaust) in each space, and each room served by the system must be identified. The system control settings and the outdoor condition during the tests shall be recorded. Also measure the return air flow at the transfer openings between plenums above the ceiling. Equipment shall be identified and related data and performance information provided. Submit 4 copies of the Test, Adjusting and Balance report. e. The Contractor shall insure that all emergency exit lighting in dormitories 3 and 4 is operating with the required illumination. 4. Dormitory Building No. 2 In the basement of Dormitory Building No. 2, Center construction has created an imbalance in the air distribution of the HVAC system. Modifications to the system include: a. Remove the supply registers installed in the dorm rooms and rotate them so that the blades defect the air at the ceiling not the floor. b. In the basement of building II, room #002 has been subdivided into two classrooms. Presently there are supply register in both rooms but no returns. Remove the 48 x 24 return register in the corridor, patch to opening left and extend the ductwork east and into the two rooms and install two 24 x24 return registers. Line the new ductwork to control sound. B. ARCHITECTURAL Only as necessary to complete the work described above. C. STRUCTURAL Only as necessary to complete the work described above. D.
