STATEMENT OF WORK

SCHRIEVER AFB, CO

PROJECT TITLE: Install Gas Heaters – B122

PREPARED BY: Anthony Chin

1. BACKGROUND

The Indoor Running Track facility (B122) is constructed of a fabric tension structure. It’s not insulated and no HVAC system is installed. During cold weather the air inside the structure tends to stay cold longer even when the ambient air temperature outside rises. This makes for harsh environment for airmen to perform the USAF mandatory physical fitness tests in the winter months. A heat source is needed to provide some warmth during PT testing events to prevent participants from the potential of muscle injuries due to cold air temperature. The heated air shall be directed generally at the testing participants on the indoor running track.

The heat source shall be turned on only for the duration of the fitness testing, and turned off at the conclusion of each test event. Because the structure is not insulated any heat produced by the heat source, that is directed at the testing participants inside the structure, will not remain in the structure for long. It is critical that the heat source gets turned off at the conclusion of each testing event to conserve energy.

2. PROJECT GOALS: Install 2 outdoor gas heaters with a minimum air flow rate of 5000 cubic-feet per minute (CFM) each, and their associated components, on the outside of each end of B122 (see drawing for proposed locations). A 200-ft flex duct per heater shall be installed (hung) on the rafters at such height (10’-12’ above floor level) that the heated air can be directed onto the track where PT test participants perform their running/walking portion of the test. The outdoor gas heaters shall be connected to the base Energy Management Control System (EMCS) so that the gas heaters can be controlled for better energy conservation.

Contractor shall coordinate with the EMCS contractor to facilitate the connections.

3. SCOPE OF WORK: The contractor shall provide all labor, materials, equipment, and supervision to perform the following tasks in conformance with the contract Final Specification.

3.1. Install 2 outdoor gas heaters, one on each end of B122. Each gas heater shall have a minimum air flow rate of 5000 CFM, a minimum of 300 MBH input and output air temperature rise of 20-60 °F.

3.2. Each heater shall be placed and secured on a 7’x6’x4” thick concrete pad. Ensure proper drainage for the pads. The grounds where the pads are to be located shall be compacted sufficiently, prior to the concrete pad installation, to prevent future settlement of the concrete pads.

3.3. Trench and install a gas line for each of the heaters. Tap into existing gas line located at the center length of B122. Install a gas pressure regulator for each heater if regulators are not included with the heaters.

3.4. Trench and install electric lines and associated components, such as circuit breakers and conduit, to provide power to the heaters.

3.5. Construct and install air supply and return plenums for each heater. The plenums shall be insulated externally to prevent loss of air velocity inside the plenums. A solid air supply transition duct shall be provided by the contractor for each heater. The solid transition ducts served to connect the flex duct and the air supply plenums from the heater.

3.6. Acquire and install flex duct assemblies inside the structure (one on each side) running the length of the structure. The flex duct assemblies shall be installed at height and positioned to allow optimal heated air directed on the running track. Secure the flex duct assemblies on the structure’s rafters with cables, clamps, tracks or equivalent fasteners. Holes shall NOT be drilled into the rafters for the purpose of securing the flex duct assemblies.

3.7. The installation of the solid transition ducts between the plenums outside of the structure and the flex duct assemblies inside the structure will necessitate cutting the structure end wall fabric. Since the fabric for the structure is under tension, the contractor shall ensure holes cut into the structure end wall fabric to accommodate the transition ducts, the edges of the fabric will not tear and propagate over time, by installing a set of ring clamps or equivalent securing the cut edges from tearing, while provide a smooth transition between the air plenums and the flex duct assemblies. A set of air return transition ducts may be required, and the holes cut into the fabric for the return air transition ducts shall be treated to prevent fabric from tearing.

3.8. Install thermostats for the heaters at locations inside the structure best represent the overall air temperature inside the structure near ground level. Proposed location(s) are midway of the facility below the flex duct approximately 4’-5’ above ground level.

3.9. Contractor shall provide connectivity between the gas heaters’ controls and the base EMCS so that ATCC is able to turn on and off the gas heaters remotely.

3.10Contractor shall protect the rubberized running track, the artificial turf and all existing equipment inside the facility from damage during installation of the heating systems. If moving any of the equipment is needed for area access, contractor shall return the equipment to their original locations at the conclusion of the project.

This does not relieve the contractor from responsibilities of performing work in a timely manner, except when the base is closed by the Installation Commander for weather. For base closings or delayed reporting due to weather, call the base information line at 567-SNOW (567-7669) or monitor local news stations for weather conditions at SAFB.

19 SECURITY REQUIREMENTS:

Contractor is required to provide identification badges for their employees. All Contractor personnel shall wear these badges while on SAFB. Badges are required to identify the individual, company name, and be clearly and distinctly marked as Contractor. These are not substitutes for visitor, temporary or any other SAFB generated badges.

The contractor shall comply with all SAFB security requirements. SAFB is a controlled/restricted area and special security procedures are utilized to deter espionage, sabotage, and theft of Air Force resources. The contractor shall be responsible for security of his work areas in cooperation with applicable base agencies.

The contractor shall appoint, in writing to the Government, a Security Representative to arrange all needed security support for this contract/project. Contractor shall coordinate security matters with the 50 Civil Engineer Squadron (50 CES) and other base agencies, as needed. Assistance from the 50 CES Security Manager and 50 Security Forces Squadron (SFS) personnel will be provided to the contractor’s Security Officer.

It is the sole responsibility of the Contractor to obtain any and all required escorts prior to starting work, if needed by the contract.

The contractor shall request, obtain and properly use vehicle passes for all vehicles used in the performance of this contract, in accordance with AFI 31-204 PARA 3.2, Air Force Motor Vehicle Traffic Supervision.

To qualify for unescorted entry to SAFB an employee shall obtain a favorable NAC. The contractor shall initiate the NAC by completing a Standard Form 85P, using the latest version of the Electronic Personnel Security Questionnaire (EPSQ) program (available for download at Website www.dss.mil). The NAC requires the employee to authorize an “employment,” “residence,” and “criminal” history records check, and submit to fingerprinting. The Government shall conduct and cover the cost of the actual NAC. Upon favorable adjudication of the records check results, interim unescorted entry may be granted pending completion of NAC. Unescorted entry based on a favorable records check will be limited to Area 7 (main base portion of SAFB).

The contractor shall direct each eligible employee to personally report to their Security Representative who will work with the 50 CES Security Manager for completion of the AF Form 2586 Unescorted Entry Authorization Certificate. Contractor employees will not be http://www.dss.mil/ allowed unescorted entry to SAFB secured buildings until these procedures have been completed.

Employees without unescorted entry authority will be continuously escorted while in a restricted area. The restricted/controlled area badge shall only be valid for the employee’s term of employment or for the duration of the contract, whichever is shorter. Upon employee termination, the contractor shall surrender the restricted/controlled area badge to 50 SFS Building 15, Pass and Registration Office, no later than 3:00 p.m. on the following workday.

When inside restricted area, contractor personnel shall, at all times, display restricted/controlled area badges on their outer garments above the waist. Remove and secure the restricted/controlled area badges immediately upon departure from the restricted area to prevent loss. Incidents of a person not properly displaying badges or violating escort procedures (e.g. working out of view of escort) shall be treated as a breach of security and that person shall be susceptible to apprehension, search and detainment. Any person inside a restricted area without a restricted/controlled area badge will be detained or apprehended, searched, removed, and turned over to appropriate authorities for disposition. The contractor shall insure personnel are briefed on base security requirements.

Access to classified information by contractor personnel during performance of this contract is prohibited. However, contractor performance shall be within controlled areas that shall require contractor compliance with various levels of security and require certain established personnel security entry control procedures.

The installation commander reserves the right to deny entry to SAFB to any person whose NAC is unfavorable or upon disclosure of information that indicates the individual’s continued entry to SAFB is not in the best interest of the USAF. Additionally, the violation of or deviation from established security procedures by any contractor employee may result in the confiscation of restricted/controlled area badges and denial of future entry to SAFB.

Restricted/Controlled Area badges issued to contractor personnel are subject to recall for inventory and verification purposes. Contractor personnel shall surrender restricted/ controlled area badges to Government personnel conducting such inventory and/or verification immediately upon notification.

The contractor shall provide an Employee Access List (EAL) to the Contracting Officer and the 50 CES Security Manager by the second workday of each month or as requested. The EAL shall be maintained current and correct at all times and shall include the name of each employee and their restricted/controlled area badge number, and vehicle listing with description. The EAL shall be on company stationery and signed by the contractor’s Security Officer or an Officer of the Company.

50 SFS personnel will verify the identity and entry authorization of each contractor employee and vehicle, and may conduct a search of any baggage, articles, or vehicles on SAFB.

Contractor employees requiring entry, but not requiring unescorted entry, will be issued a visitor badge and will be under direct surveillance at all times by a contractor employee possessing a restricted/controlled area badge with escort authority. Contractor employees entering SAFB will obtain their visitor badge from the 50 SFS, Building 15. The visitor badge will be returned to the entry controller each time the employee departs the SAFB controlled area. While within the SAFB controlled area, contractor personnel will display the visitor badge on their outer garment above the waist and shall remain at all times within view of the escort official. The escort for all contractor personnel shall maintain positive visual contact with escorted employees at all times.

The contractor shall immediately report the occurrence of lost badge(s) to the 50 CES Security Manager, who will in turn report to 50 SFS. If the 50 CES Security Manager is not available, the loss shall be reported directly to 50 SFS within one duty day of loss. Replacement badge will not be issued until reporting procedures are satisfactorily completed.

All costs incurred by the contractor associated with security requirements (with exception of the NAC investigations) including submission of necessary security investigation paperwork, routine entry/exit delays, and operational delays due to contingencies or exercises, are to be anticipated by the contractor and shall be included in the price of the contract. Base exercises are estimated to occur approximately 15 workdays per year; however, during contingencies and exercises the contractor’s work will normally be rescheduled.

The contractor shall obtain all necessary cards, passes, buttons, decals, or other items required for access to the area or areas in which work will be performed. The contractor shall apply for all vehicle and individual identification media at the SAFB Security Forces Squadron;

Visitor Control Center, Building 15. All personnel operating a vehicle on SAFB shall obtain a vehicle registration pass. The contractor shall provide proper state registration, proof of insurance, valid driver’s license and proof of vehicle emissions testing in order to register the vehicle and drive on base. Upon completion or termination of the contract or an individual’s employment on the job, the contractor shall immediately retrieve the identification media issued above and surrender it to the Security Forces, SAFB Visitor Control Center, and Building 15.

On average, approximately 15 times per year, for four hours in duration, small portions of the installation will be closed to non-essential personnel due to disaster, emergency and contingency responses or exercises. This does not relieve the contractor from responsibilities of performing work in a timely manner, except when the base is closed by the Wing Commander for weather.

The contractor shall comply with the Department of Defense Instruction (DODI) 1402.5, enclosure 6, paragraphs E6.2.2.1, E6.4, E6.4.3, E6.6, E6.6, E6.10, E6.10.6 and AFI 34-248, chapter 5, paragraph 5.3 criminal history and background checks on any employee working in the Child Development Center.
