About this file
This is a Questions and Answers (Q&A) document for solicitation XTLF-21-1031, addressing contractor inquiries regarding the Repair Natural Gas Phase 1 & 2 project at Vance Air Force Base, Oklahoma. The Q&A clarifies scope, technical requirements, and administrative procedures for this firm-fixed-price natural gas distribution system repair project.
The project scope is limited to Phase A (Phase 1) and Phase B (Phase 2) only, with a combined maximum contract duration of 240 days. Key deliverables include underground polyethylene gas main and service line installation, including 8-inch and 4-inch MDPE piping with associated valves, regulators, and meters equipped with pulse output (though meters will not be connected to monitoring systems). The contractor must handle all exterior connections to buildings, including risers, valving, regulators, and meters, with base personnel handling internal gas reactivation. Existing polyethylene materials match SDR 11 PE 2708 specifications. Critical requirements include pneumatic testing at working pressure for 24 hours, 24-inch minimum cover below grade, warning tape for open-cut installations, and tracer wire for both open-cut and horizontal directional drill (HDD) methods. The contractor bears responsibility for all testing, ODEQ stormwater permits, material sourcing, and off-base disposal of excess excavated material. Performance bond at 100 percent and payment bond at 50 percent are mandatory; no bid bond is required. Working hours are 0700-1645 weekdays with coordinator approval required for extended hours, weekends, or holidays. All permits, utility locates, and escorts are government-provided. The project is tax-exempt as a government undertaking under Oklahoma law.

Please define where 6-foot screened chain-link fence is required versus orange/safety fence, and confirm whether the entire active utility alignment must be enclosed or only staging/storage and specific work areas. | The laydown area does not have to have a 6' chainlink fence. The work areas need to have a construction fence to provide safety to base personnel. |
| 67 | All Zones / 01 74 19 §1.2 | Section 01 74 19 states “Divert a minimum of percent by weight” but does not provide a percentage. Please provide the required minimum construction-and-demolition waste diversion percentage and identify any mandatory material-specific recycling/salvage requirements applicable to this project. | all materials should be recycled as much as possible, but no minimum number is required by the base. |
| 68 | All Zones / 01 14 00; 01 00 00 §§1.28-1.30 | Please identify which planned work areas are within controlled, restricted, flightline, or other mission-sensitive areas and provide the associated access/escort requirements, badging lead times, vehicle/equipment restrictions, FOD controls, work windows, aircraft-operation constraints, and any requirement for dedicated escorts or spotters that must be included in the bid. | Phase 2 has the only work that would be in the controlled area. This includes Building 129, 119, 125, 121, 116. This area will require a UEAL form to be completed for contractor to work unescorted in this area. The form is completed by the construction manager with names of contractor to be working in the area. |
| 69 | Existing Facilities / 01 00 00 §1.18; 02 81 00 referenced | The specifications address potential lead-based paint and asbestos and reference a hazardous-material disposal section that is not included. Please provide available hazardous-material surveys for existing piping, coatings, meters/regulators, vaults/boxes, and affected building penetrations, and define whether sampling, abatement, packaging, transport, and disposal are included in the Contractor’s bid or handled by the Government. | No asbestos is anticitpated on this project. Lead based paint maybe present, wet cut any suspected lead based paint and recycle the pipe. No abatement is required for lead based paint. |
| 70 | Crossings / 33 11 23 §2.8; 33 51 15 §3.7.2 | The specifications require steel casing “where indicated” at crossings, but the crossing/casing schedule is not provided. Please identify each location requiring casing and provide carrier-pipe size, casing diameter, casing material/coating, wall thickness/schedule, length, installation method, insulating spacer requirements, end seals/bushings, vent requirements, and minimum cover. | The steel casing is shown on the drawings. |
| 71 | All Trenches / Services / 31 00 00 §3.10.1; 33 11 23 §§3.1.2.3, 3.1.4.1; 33 51 15 §3.7.2 | The specifications contain conflicting minimum-cover requirements: Section 33 11 23 states buried PE piping is to be 24 inches below finished grade, while its service-line paragraph allows 18 inches; Section 33 51 15 states 24 inches for mains and 18 inches for services; and Section 31 00 00 states 18 inches in rock and 24 inches in other excavation. Please provide the governing minimum cover for each main/service size and installation condition (normal soil, rock, pavement/roadway, HDD, casing, and building approaches), and identify any locations requiring greater cover or encasement. | Proceed with 24" below grade. |
| 72 | All Zones / 31 00 00 §§2.1-2.2, 3.8.1-3.8.2; 33 05 23.13 §§2.2.4, 3.2.7; 33 51 15 §3.7.2 | Please reconcile the buried identification requirements for new plastic gas piping. The documents variously require detectable warning tape, detection/tracer wire, and HDD-specific minimum #12 AWG copper tracer wire, while the earthwork section describes detection-wire termination at manholes/valve pits that may not exist on this gas system. Confirm whether both warning tape and tracer wire are required for open-cut and HDD installations, and provide required wire gauge/type/insulation, vertical placement, termination/access or test-box locations, bonding/grounding requirements, and requirements at casings, risers, and valve boxes. | Warning tape is only required for open-cut, however tracer wire is required for both open-cut and HDD. |
| 73 | All Zones / 01 57 19 §§1.4, 3.1.1-3.1.1.4 | Section 01 57 19 requires Construction General Permit coverage, a project-specific SWPPP, NOI/permit fees, BMP inspections, and reporting as applicable, but the current package does not establish total disturbed acreage by zone or how multiple-zone awards will be permitted. Please provide the anticipated disturbed acreage for each zone and confirm whether Construction General Permit coverage is required for this procurement. If required, state whether one or separate NOI/SWPPP packages are required by zone/award, who will be the permittee, who is responsible for permit fees, and the required inspection frequency and inspector qualification requirements. | Contractor will be responsible for all ODEQ permits and fees. Contractor needs to figure SF of disturbed area based on whether they will open trench or bore. One permit is acceptable per award. Contractor will work with ODEQ for permit required inspections. |
