I. Introduction

The objective of this project is to provide the design for the renovation of the first floor office restrooms, the customer service office, and the warehouse restrooms, within Building 977 at Travis Air Force Base. The building, which houses the base’s Air Freight Terminal, was constructed in the late 1960’s and early 1970’s, and although it’s undergone a variety of small renovations since that time, many spaces within the building remain outdated and insufficiently equipped to serve the current mission. These renovations include the architectural, mechanical, electrical, plumbing, and fire protection services necessary to provide the code-compliant spaces required by the Scope of Work suitable for supporting the current mission. These renovations focus primarily on upgrading the user comfort within these spaces, including finishes and temperature control, and ensuring that the renovated spaces meet all applicable criteria. In addition to the renovations mentioned, the Scope of Work also includes specific measures to improve the thermal comfort and safety of personnel working within the warehouse area of the freight terminal, as well as Shop 112.

II. Existing Conditions

Opened for operations in the early 1970’s, Building 977 has been in continuous operation for nearly 50 years, serving as a primary terminal for air freight traveling to, from, and through the western United States. The warehouse side of the facility is a 100,000 square-foot steel framed structure clad with metal wall panels and low-sloped roof. To the east, south, and west of the enclosed warehouse are additional open-air steel structures providing shelter for other terminal operations. The office portion of the building, which is a CMU structure to the north of the warehouse, encloses approximately 40,000 square feet of mixed office and shop space. The building sits near the northwest corner of the flightline, adjacent to the South Gate off Peterson Road.

The first floor office restrooms most recently had their fixtures and accessories upgraded within the last ten years, but the finishes haven’t been upgraded in several decades, and have fallen into dis-repair. Additionally, none of the restrooms throughout the building are currently accessible by ABA Standards. The access corridor which connects the men’s restroom to the warehouse floor has also suffered extensive wear and tear over the years, resulting in damaged finishes, insufficient lighting, and a lack of fire alarm signaling, all of which are to be addressed through this project.

The warehouse area is served by an additional set of male and female restrooms on the east side of the facility which are in similar condition, and need similar repairs, as the office restrooms referenced above. Although these restrooms are not UFAS compliant either, there are additional barriers which make these harder to upgrade than the office restrooms, and since all occupants with access to the warehouse restrooms have equal access to the office restrooms, the authority having jurisdiction at Travis AFB has determined that these restrooms do not need to be made UFAS compliant as part of this project. As a result, this part has been omitted from this Scope of Work.

Like the office restrooms, the customer service office, which houses the transport operations and scheduling team, has outdated finishes and furnishings in need of upgrade. Additionally, the mission for this space has evolved over the years, rendering the currently layout insufficient.

A concrete vault has been repurposed as a break room, without the provision of plumbing for a

Page | 4 sink or appliances, or the installation of the customary furnishings. A large closet has been constructed in the corner of the space to house a telecom rack, but without any HVAC service to the office, this closet is underserved.

The warehouse floor itself is a large cavernous space with several roll-up doors to the exterior.

Over the years, the use of diesel powered fork-lifts has worn off the traffic striping on the warehouse floor, and discolored the insulation panels lining the walls. Over time, these insulation panels have come dislodged one by one, and have begun to fall to the warehouse floor, causing a safety concern for occupants and reducing the thermal insulation against the hot summer and cold winter temperatures. Adding to the issue of thermal comfort, the gas-fired heaters installed to warm the space in the winter are old enough that they can no longer be easily serviced, and their rate of failure increases with every year.

ASHRAE 90.1

ASHRAE 189.1

Government Standards:

The Unified Facilities Criteria (UFC) are required by this project are referenced in the contract documents or cross-referenced within referenced documents. The following are significant UFC’s available on the website that are applicable to this project:

UFC 3-420-01; Plumbing Systems, with Change 10

All aboveground domestic water and waste/vent piping systems, in the Men’s and Women’s Toilet/Locker rooms, shall be removed back to the limits of these areas, except for the piping within the block plumbing chases. The piping inside these chases will be retained up to the connection point above the chase walls in the ceiling cavity of the first floor. The piping system will need to be isolated off to allow the remaining areas of the building to continue to operate.

Addition of temporary valves may be required for isolation with short building outage (prearranged). All plumbing fixtures shall be removed, and all associated appurtenances removed to the connection at the plumbing wall or at the floor. The underground waste piping shall be video taped from accessible points within the space to the exterior of the building.

From this video footage, it will be determined what approach the underground plumbing will take.

All aboveground domestic water and waste/vent piping systems, in the Warehouse Restroom area, shall be retained to the supply stops at each fixture. All plumbing fixtures shall be removed, and all associated appurtenances removed to the connection at the wall or at the floor. Slab cutting will be kept to a minimum to allow for the reconfiguration of the restroom area and associated fixtures.

The Second Floor Restroom floor drains will be removed in their entirety, including the waste piping below in the first floor ceiling space and re-piped as part of the First Floor work.

In the Men’s and Women’s Toilet/Locker Rooms, all new efficient plumbing fixtures will be provided in an updated arrangement (based on architectural layout). The domestic piping

Page | 11 systems will connect to the mains at the wall line, where piping is not concealed within concrete masonry unit walls, and all new distribution will be installed to serve the fixtures with the require utilities, including the connection points at the top of the plumbing chase walls that serve all the associated fixtures. Pending the video results, if acceptable, the existing underground waste system will be “jet-flushed” and reutilized to greatest extent possible to minimize the slab cutting.

In the Warehouse Restroom in the northwest corner of the Warehouse area, all new efficient plumbing fixtures will be provided in the same arrangement (based on architectural layout). The domestic piping systems will connect to the fixtures with the require utilities. The existing underground waste system will be reutilized to greatest extent possible to minimize any slab cutting.

The Second Floor Restrooms will have a new floor drain installed in each space that will be re-piped back to the main in the first floor ceiling space. The floor drain body will be installed to coincide with the flooring system so as not to allow water infiltration through or around the floor drain assembly and into the first floor ceiling area.

Customer Service Office (112) will require waste, vent and domestic water to serve a new kitchenette sink in the existing vault area. This will require core drilling through the back of the vault and tie into plumbing utilities within the existing water heater room.
