STATEMENT OF WORK

REPLACE COOLING SYSTEM, B448

PROJECT LOCATION: Laughlin AFB, TX

BASE PROJECT NUMBER: MXDP 16-1040

08 JUNE 2018

1.0 INTRODUCTION

Services are required to replace the existing central energy plant at Building 448 with a new cooling system and reduce the rising maintenance costs resulting from the inefficient/inoperable heating, ventilation and air conditioning (HVAC) system. The completed project shall include the replacement of the chiller, cooling tower, pumps and pipes. Failure to provide this project will allow numerous dorm rooms in building 449 and 450 to remain unusable due to the lack of HVAC, which will drive up the cost of housing students on the local economy.

The Contractor is required to attend a Pre-Construction Conference after the first NTP is given, prior to the start of ordering and delivery of supplies/materials and construction. The Government will notify the Contractor when this conference will be held. The NTP for the construction phase will not be issued until the order and delivery phase is complete unless otherwise approved by the Contracting Officer.

The Period of Performance (POP) for the submittal phase will be 120 calendar days from the start date identified written on NTP #1, the POP for the ordering and delivery of supplies/materials phase will be 60 calendar days from the start date identified on written NTP #2, and the POP for the construction phase will be 198 calendar days from the start date identified on written NTP #3.

2.4 Submittal Phase

Contractor shall provide required submittals as indicated on AF Form 66, Schedule of Material Submittals (Item 12).

The Contractor shall provide electronic copies of all required submittals.

The Contractor shall provide submittals on the schedule, materials, and Safety Data Sheets (SDS) for Government review. All construction materials and submittals shall be approved prior to issuance of NTP #2. The Government has 14 calendar days to review each submittal in order to approve or disapprove the submittal.

2.5 Order and Delivery Phase

Upon issuance of NTP #2 and approval by the Contracting Officer, the contractor shall begin ordering approved materials and supplies required to complete construction. Contractor shall have 60 calendar days to order and receive all materials and supplies and have them ready to utilize once the construction phase begins.

2.6 Construction Phase

Upon the approval by the Contracting Officer, the Contractor may commence onsite construction activities and shall complete the work.

2.7 Pre-Construction Kick-Off Meeting

47 CONF will host a pre-construction (i.e., Kick-Off) meeting to advise and coordinate on local procedures, safety and security requirements, and project coordination activities. The CO Representative (COR) will arrange for a suitable Kick-Off meeting location. The COR will schedule the pre-construction meeting after NTP #1 and before NTP #3. No submittal is required for this meeting. This meeting will be an opportunity for the Contractor to meet with stakeholders, end users and maintainers in order to ensure a full understanding of the scope of work. The COR will ensure the appropriate base agencies attend the Kick-Off meeting to provide necessary information or briefings to facilitate the success of the contract effort. This shall include stakeholders such as the base Fire Department, Bioenvironmental Engineering Flight, Wing Safety, Civil Engineer Squadron, the user, etc.

During the meeting the Contractor shall present a complete overview of the project, review the schedule, highlighting any issues (review periods, material submittals, etc.) which are key to maintaining the schedule. The Contractor shall take meeting minutes to include the recording of the attendance list and the Contractor shall send the meeting minutes to the CO.
