This statement of work (SOW) defines requirements for Design Build (D-B) services to provide civil/structural-engineering design and construction to repair the sewage line of building 1330, at Mountain Home AFB (MHAFB), ID.

In carrying out the work assignment issued in this task order, the Contractor shall furnish the personnel, services, equipment, materials, facilities, and other requirements necessary for, the performance of work set forth herein.

Primary technical services will be performed by individuals who are credentialed members of architectural, science, and engineering professions. The credentialed professional(s) (a) will be licensed (e.g., registered professional engineer) to practice in the state where the facility is located and (b) commands the necessary expertise, in terms of knowledge and experience, to undertake the specified task.

PROJECT HISTORY

Building 1330, addition, was constructed circa 1996 to support MHAFB sheet metal shop.

Approximately 107’ of sanitary service (SS) line has degraded to the point of failure. The failed, SS service line begins at the 24” Main SS just outside the facility. According to the As built drawings, the failed SS service line enters building 1330 below the exterior foundation, and under a 6” thick (th) slab that is reinforced with welded wire fabric. The 6” th concrete floor was (re)coated with Chemically Resistant Urethane, (CRU) in Dec. 2022.

There is a lateral SS line approximately 30’ long, that serves an emergency shower. The 30’ SS line is connected perpendicular to the 107’ SS line. The Storage Room located building north of the room containing the emergency shower, is equipped with a floor drain that is not shown on the attached As-build drawings.

A. SCOPE OF WORK

The Contractor shall provide all investigative, design, and construction services required to restore with new SS in accordance with the IPC, and the ACI. No Government furnished equipment will be provided.

1. Site survey and investigations. The as built documents are for reference only. On site determination and field verification is the responsibility of the Designer of Record (DOR) and contract holder.

a. Conduct an on-site investigation to verify the location and existing conditions of the service line for the floor drain in the storage room.

b. Conduct all necessary core samples, investigations, pipe camera, and tests to verify existing conditions of the entire project and document the findings on the 60% Design submittal.

c. Contact CE for dig permits and utilities location a minimum of three weeks prior to destructive testing and investigations.

Project: 1051335 – Rpr Main Sewage Line, B1330

2. Provide a stamped, 100% Design with Drawings, Specifications and Design Analysis. Milestones shall include 60%, 90% and the Final, 100% Design submittals for Government review. Each Design milestone must be followed by a Design review meeting conducted by the DOR/contract holder.

3. Demolish all SS system from the 24” SS Main to the clean out (CO) located within the women’s restroom and the floor drain located in the storage room.

a. Control all airborne debris to protect all personnel and property.

b. Access to remove and replace with new SS system.

i. Approximately 107’ SS from CO at the 24” SS Main to the CO located within the women’s restroom.

ii. Approximately 30’ of SS lateral from the sheet metal storage room 103 to the 107” SS as described above.

c. The SS line, for the emergency shower will be capped and abandoned in place.

d. Remove the emergency shower in room 105, cut and cap plumbing to conceal in new floor and wall finishes.

4. Construct new SS system from 24” SS main to the CO located within the women’s restroom and the lateral and floor drain located in the sheet metal storage room 103.

5. Repair asphalt outside the facility to meet or exceed existing.

6. Repair 6” th, concrete slab in accordance with the ACI.

a. The existing conditions are keyed joints traversing the path of the SS system.

7. Repair with new floor finishes for entire floor of emergency shower room 105.

8. Repair and repaint from corner to corner, all disturbed walls in emergency shower room 105.

9. Finish the concrete floor with CRU coating used in the project ending Dec. 2022 or equal.

10. Upon completion of the project, provide AutoCAD (2018 or newer) as built drawings with all digital linework and annotations to document all as built conditions. No hand drawn redlines.

11. Survey all new plumbing prior to covering, see also attachment 9.

General Comments:

1. Conduct Regular Quality Control Meetings: Conduct a meeting for the “three phase inspection” process for each definable feature of work throughout the entire construction phase. Include Section 01 45 00 Quality Control, (see also Attachment 1. General Requirements paragraph 20) in design specifications to include the “Three Phases of Control”.

2. Facility Use during Construction: Building 1330 will be occupied during construction at the building east, half of the sheet metal shop. Erect a dust barrier to completely isolate all debris from entering occupied portions of the facility.

3. Operating Hours: On-site work will be during normal business hours that run 24 hrs a day excluding Saturdays, Sundays, federal holidays and family days. Request facility access 2 weeks minimum prior to onsite activity. Request a most current list of family days.

4. Soils: The soil at B1330 will need to be reused onsite or tested to determine if the soil can:

a. Be reused on base,

b. Disposed of at a permitted Subtitle D landfill or

c. Disposed of at a permitted Subtitle C landfill (depends on the test results).

5. As-Built Drawings: The attached as-built drawings are provided for Building 1330 for reference only, field verification is required.

6. Entry Authorization List (EAL): Building 1330 is in a controlled area. An EAL will be required for all on-site work. The EAL may require up to 2 weeks to process. Request an EAL form from CES; contact jason.thomas.79@us.af.mil, office phone 208-828-2723.
