The contractor shall make efforts to minimize interference to Government operations. The contractor shall coordinate and schedule work with the 673 CES/CEPM office prior the start of any operation. The contractor shall dispose of all construction debris off base at an approved disposal facility. All hazardous waste (HW) generated by the contractor on Joint Base Elmendorf- Richardson (JBER) will be managed by the contractor in accordance with federal regulation applicable to large quantity generators (LQGs) of HW. All universal waste (UW) handled by the contractor on JBER will be managed by the contractor in accordance with federal regulation applicable to large quantity handlers (LQHs) of UW.

All disposal costs for generated waste shall be borne by the project.

2.3 SITE SECURITY AND PROTECTION: The contractor shall make every effort to secure the work site, allowing only authorized personnel to enter the work site. The contractor shall protect the site from damage from weather, vandalism, and/or theft.

2.5.1. Prior to contractor transporting any hazardous material onto JBER the contractor must provide a current copy of the manufacturer's Safety Data Sheet (SDS) to the Contracting Officer for certification. No hazardous materials for this project shall be allowed on base until the contractor has received written approval of the submittal for the material in question from the Contracting Officer, to include a valid Safety Data Sheet (SDS). If it is a different manufacturer from that originally submitted, a new SDS submittal will be required.

2.5.2. All material tracking shall be done on the Hazardous Material Tracking List which must be; 1) submitted initially, 2) whenever new hazardous materials are added to the project (minimum of sixty days between updates) and 3) a final update when leftover materials are removed upon completion of the project. Prior to final acceptance of this project, the contractor must submit a listing of all hazardous materials used in the performance of this project.

2.6 GREEN PROCURMENT: Contractor must incorporate “green procurement” principles into the design of their projects. Specifically, consult the EPA’s web site at www.epa.gov/cpg/products.htm for a listing of the products that have been mandated as green procurement requirements for purchases.

SECTION 3: DESCRIPTION OF WORK AND SPECIAL INSTRUCTIONS

3.1 General Requirements (Div 1) There are no drawings or design analysis available and as such, the contractor is responsible to verify locations for installations with the user and 673 CES project manager before construction begins. Ongoing communication and coordination with the user is expected.

3.2 Existing Conditions (Div 2) Building 10415 is a critical facility for training. Chiller outages have taken this building offline for over a week at a time. The training must be transferred out of state during these outages at enormous cost. In order to eliminate these outages, a backup chiller system was installed and the existing chiller was left in place until a new primary chiller could be installed. The existing primary chiller is to be replaced: a 480V modular Airstack unit by Multistack which has been damaged and is not economical to repair.

3.3 Construction (Div 3-33)

3.3.1. Demolish Existing Chiller Demolish and dispose of existing chiller, modular

Airstack by Multistack. Contractor shall ensure that existing glycol supply lines, electrical supply lines, and controls wiring are not damaged in any way that would interfere with continued operation of the existing backup chiller.

3.3.2. Glycol Lines Tie in to existing glycol lines to create new supply and return for replacement primary chiller. Provide new insulated and shielded supply and return lines for replacement primary chiller and ensure shutoff valves will allow isolation of replacement primary chiller or existing backup chiller. Connect new glycol supply and return lines to backup chiller pump module. Ensure that existing additional tees and isolation valves remain and are unobstructed to allow connection for the 773rd CES temporary trailer mounted portable chiller unit.

3.3.3. Equipment Pad A pad has been poured for a temporary chiller in the proposed location for the new chiller. After equipment selection, verify that the pad meets the chiller manufacturer’s specifications for installation. If so, use the existing pad to install the new chiller. If the existing pad does not meet the chiller manufacturer’s specifications, provide new concrete pad in accordance with chiller manufacturer’s specifications. Location for the new pad shall be adjacent to the existing chiller and shall be coordinated with 673 CES and the user before construction begins. Chiller must be located to allow access for maintenance to include clearance for removal of component assemblies.

3.3.4. Electrical Tie in to existing 480V electrical supply for existing chiller. Ensure that manual transfer switch allows switching power from primary chiller to backup chiller. Provide new conduit and wiring suitable for the new primary chiller and connect wiring to backup chiller. Ensure that one 120V receptacle for maintenance is provided within 25 feet of the new chiller.

3.3.5. Install Chiller Provide and install new primary chiller, Trane CGAM 52, with free cooling capacity of at least 30 tons, active cooling capacity of at least 50 tons, utilizing a scroll compressor, plate heat exchanger, dual high head pumps, strainer, extreme low ambient (-20F) operation, and freeze protection. Location for new chiller shall be coordinated with 673 CES prior to installation.

3.3.6. DDC Controls Install DDC controls to backup chiller to replicate all functions provided by the current DDC controls on the existing chiller to include, but not limited to: chilled glycol return temperature, chiller pump status and alarm, and free cooling fan alarm and amperage draw. Provide full compatibility and interoperability with the existing basewide EMCS system and all required updates to the EMCS software and graphics. Ensure that all installed equipment contains no radio connectivity to include WiFi and Bluetooth.
