Spec language

Specification paragraphs you can paste into a solicitation.

Seven sections, numbered, written so any bidder can answer them and a vague answer is easy to see. Copy a section as written or edit it to your program. Every paragraph describes how HLE builds; none names a brand or a builder.

  1. 1. Body construction
  2. 2. Materials
  3. 3. Electrical
  4. 4. HVAC
  5. 5. Compliance and testing
  6. 6. Warranty
  7. 7. Documentation required with the bid

Which sections apply: an HLE-built body on a chassis, and an HLE-built trailer, take every section as written; the trailer is built with the same cage, sidewalls, roof and floor as the vehicles. A van upfit (Transit, Sprinter, ProMaster) keeps the factory body, so it takes the insulation, electrical, cabinetry, water-test and delivery sections and not the cage, sidewall or roof paragraphs.

1. Body construction

1.1 The body shall be built on a welded steel cage of 1.5 in square steel tube. All structural steel shall be powder-coated on every surface before the body is assembled. Insulation shall be closed-cell board cut to each frame cavity and glued in place; stuffed or spray-patched insulation shall not be accepted. The bidder shall state the tube section and when the coating is applied.

1.2 Cage tube shall be stitch-welded no more than 6 in apart and built on the chassis, not on a jig and lifted on. The roof tube shall be doubled and the rear wall X-braced. The skirt shall be welded to the cage as part of the structure, not a separate panel screwed on at the floor line. Door openings shall be framed in steel inside the cage.

1.3 Each sidewall shall be a single pressure-laminated panel from roofline to skirt, with no horizontal seam. Window openings shall be cut from the panel. The bidder shall state the number of pieces in each sidewall and the location of every seam.

1.4 The roof skin shall be a single piece bonded to the cage over a steel roof structure. Fiberglass-reinforced plastic (FRP) roof skins shall not be accepted. Every roof-mounted air conditioner, mast or antenna shall bolt to a steel plate welded into the roof structure. The bidder shall name the roof skin material and state where its seams fall.

1.5 The subfloor shall be a resin-infused composite that does not absorb water, laid over the cage and sealed at every seam and wheel well. Plywood subfloors shall not be accepted. Where the use calls for it, the floor covering shall be seamless medical-grade sheet vinyl coved up the wall. Wheel wells shall have welded backers.

2. Materials

2.1 Every structural steel component shall be sandblasted, chemically washed and powder-coated before assembly. Primer or paint on structural steel shall not be accepted. The bidder shall state the coating process and whether it covers every face of the steel.

2.2 Insulation shall fill the full depth of the frame tube, with no air gap behind the wall. The bidder shall state the insulation type and how it is fixed.

2.3 The sidewall inner layer shall not wick water. The subfloor shall be no less than 5/8 in thick, edge-encapsulated and sealed at every cross-member.

2.4 Cabinetry shall be solid hardwood with stainless hardware. Panels in wet areas (at sinks, refrigerators and wash-down floors) shall be resin-infused composite (PerformMAX 500 or equal), not plywood, with sealed edges. Particleboard shall not be used in any cabinet or panel. The bidder shall name the cabinet material.

2.5 Wire pass-throughs in steel shall be fitted with grommets so no wire rides a raw edge.

3. Electrical

3.1 Wire harnesses shall be built to length in a harness shop, with marine-grade connectors on every exterior connection. Every circuit shall be labeled at both ends. Butt connectors and tap splices shall not be used. A panel drawing for the unit shall be delivered with the vehicle.

3.2 Each harness shall be laid out on a full-size board, with wire loom over printed wire. Every electrical connection shall receive corrosion protection, not only the battery posts.

3.3 The generator, shore-power connection and battery backup shall be sized for the real equipment load, with battery backup for refrigeration and IT where the unit carries them. The bidder shall state the generator capacity and the load it was sized for.

3.4 Wiring documentation shall be delivered with the vehicle for the fleet shop.

4. HVAC

4.1 HVAC shall be sized for the unit, the people and equipment inside it, and the climate it works in. Where equipment produces heat (imaging, electronics, network racks), the system shall be sized for the equipment heat load, with humidity control where the equipment maker requires it. The bidder shall state the capacity and the load it was sized for.

4.2 Every roof-mounted air conditioner shall bolt to a steel plate welded into the roof structure, not to the roof skin.

4.3 Insulation shall give full coverage of every wall, roof and floor cavity, with no condensation pockets.

5. Compliance and testing

5.1 The vehicle shall comply with all applicable Federal Motor Vehicle Safety Standards (FMVSS). The bidder shall supply a compliance statement with the bid.

5.2 Where the purchase requires it, the vehicle shall meet the ADA vehicle accessibility requirements of 49 CFR Part 38, and the bidder shall supply the statement.

5.3 Where the purchase requires it, the vehicle shall have completed FTA bus testing under 49 CFR Part 665 (Altoona), and the bidder shall supply the test report.

5.4 For a federally funded purchase, the bidder shall supply Buy America documentation.

5.5 Every unit shall be water-tested before delivery in a spray booth under full spray for no less than 15 minutes, with a person inside checking for leaks, followed immediately by a road test with a person inside checking again. The road test shall include hard braking and acceleration. A final inspection packet, signed off by each department, shall be delivered with the vehicle.

5.6 For detainee transport: seating and restraint anchorage to FMVSS 207/210; emergency exits on bus-classified units to FMVSS 217, balanced against security; compartment and camera design to the sightline and monitoring requirements of PREA, 28 CFR Part 115.

6. Warranty

6.1 The bidder shall warrant the body structure (cage and body) for no less than 5 years / 100,000 miles, the subfloor for no less than 7 years, and the conversion for no less than 3 years / 36,000 miles, or equivalent, and shall state each term in the bid. No term shall prorate or step down with age or mileage.

6.2 The bidder shall keep replacement parts available for no less than 2 years beyond the warranty period, and shall state any exclusions (for example corrosion from road chemicals) and any maintenance the warranty requires (for example roof reseal intervals).

6.3 The chassis and drivetrain carry the chassis maker's warranty. Installed equipment carries its maker's warranty; the bidder shall handle equipment warranty claims for the purchaser.

6.4 Warranty registration and the first service date shall be completed at delivery.

7. Documentation required with the bid

7.1 The bidder shall submit: (a) a floor plan drawing of the proposed unit; (b) a response to each paragraph of this specification naming the material, section or grade used; (c) a price with major equipment itemized and customer-furnished equipment on separate lines; (d) the compliance statements required above; (e) the delivery schedule, stated in days after the signed order, deposit and chassis.

7.2 The bidder shall include with the bid: (a) a certificate of good standing from its state of incorporation; (b) its vehicle manufacturer or converter license issued by the state where it builds, where that state licenses manufacturers or converters; (c) FMVSS certification for the completed vehicle; (d) a signed Buy America certificate where federal funds apply; (e) a current certificate of insurance; (f) references for comparable units delivered, with contacts; (g) the warranty terms in writing, as required in section 6.

7.3 At delivery the bidder shall supply the panel drawing, wiring documentation, the signed final inspection packet and warranty registration.

Shorter, one-paragraph-per-part language and the compliance table are on for purchasing and bid writers. HLE's own section 7 documents are listed in the vendor packet.

Spec review

Send us your draft. We review it at no charge.

HLE will review a draft specification for a purchasing office at no charge: what a bidder cannot answer, what lets a weak body through, and where a paragraph names one maker's product. You get it back marked up.
