Clear all ticks

Pre-bid and scope

• AHJ identified (city vs county vs suburb), with the code edition and permit types confirmed. See Texas / San Antonio.
• Roof system, age and roof warranty holder identified, and the roofing contractor of record's contact obtained.
• Historic district or landmark status checked.
• Route walked and measured, with drains, crossings, hatches and edges marked.
• Cable count and growth allowance agreed with the owner, and the kit size chosen (estimator).
• Hoisting method chosen. Crane vs hoist, ROW permit and FAA 7460-1 need assessed.
• Roofer scope priced in: curb and flashing for the hood entry, plus the post-install inspection.
• Engineer of record engaged for the dead-load and wind/uplift letter.

RFIs to send ANDREW (or your distributor) before ordering

The public spec sheets leave these open. You can copy the block as is:

RFI: ANDREW rooftop cable supports
1. Wind rating: All spec sheets say "contact your local ANDREW representative".
   Please provide the rated wind speed / uplift and sliding resistance for
   [MT-F1542-11 / MT-F1543 / MT-F1595 / RT-CB4D / RT-CB8D / RT-CB12D / RT-ST]
   as installed with the included sleepers, and any ballast requirement.
2. Assembly drawings: Please send current assembly drawings with hardware
   torque values and sleeper placement for each part ordered.
3. MT-F1703 / MT-F1704: Distributor lists MT-F1703 as a 0-45 deg vertical
   hinged extension, 12 in W x 24 in L; the sheets list 40 x 12 x 20 in and
   40 x 24 x 20 in. Please confirm MT-F1704 is the 8-run equivalent, the hinge
   length, and how a 12-run (MT-F1595) bridge changes elevation.
4. CT-P4: Title says 1/4 in thick; dimension table says 1 in. Which is correct?
5. MT-F1637: Title says 1/2 in thick; dimension table says 1 in. Which is correct?
6. RT-CB4D/8D/12D: Which sleeper is included (type/material)? How are cover-kit
   sections joined (no splice part is listed)?
7. Pipe OD: MT-F1542-11 lists 2.4 in. What is it for MT-F1543 and MT-F1595?
8. RT-ST: Rated live load / foot traffic?
9. MT-365G: Lead time (non-standard product), curb dimensions and flashing detail.
10. Field cuts: Are field cuts to length permitted? If so, please authorize in
    writing per Limited Warranty section 8(g) and state the touch-up method.
11. Turns: Please confirm a 90-degree horizontal turn is two adjustable
    splices (MT-F1573-11 / MT-F1574 / MT-F1597) at 45 deg each with one full
    section between them, the minimum diagonal length, and whether any tee
    or cross part exists for the bridge line. Do sections self-splice at
    straight joints, or does every joint need an adjustable splice? May two
    splices be joined back to back without a section between? If not, what is
    the minimum diagonal length, and will you authorize cutting a section to it?
    What part covers the cables at a turn?
12. Grounding: Is the bolted splice an approved bonding connection (NEC
    392.60(A))? Where may a bonding lug or listed clamp be attached without
    voiding the warranty (section 8(g))? Is a jumper required across the
    MT-F1703 / MT-F1704 hinge?

Submittals

• Spec sheet for every part, with its revision date (current list).
• ANDREW assembly drawings.
• ANDREW written wind rating, or the engineer's ballast/attachment design.
• Engineer of record letter covering dead load, point loads on insulation and wind.
• Roof manufacturer's written approval of the layout, pad material and penetration.
• Route drawing showing sleeper locations, step-overs, entry, and the drainage paths kept clear.
• Grounding/bonding detail per the owner or carrier standard, naming the standard and revision (what it must cover).
• Firestop system data, if the roof assembly is rated.
• Lift plan, plus heat-illness and fall-protection plans.

Procurement

• Ordered through an authorized ANDREW reseller, or the warranty doesn't apply.
• Lead times confirmed, especially MT-365G (non-standard product).
• Splices counted at one per joint per tray. Sleepers come three per kit, and extra pads are ordered for any approved protection layer.
• SnapStak hangers ordered separately for the cable OD, if you're using cover kits.
• Delivery timed close to install, since the warranty clock starts at shipment.
• PO terms checked for any warranty changes.

Before mobilization

• Permit issued and posted.
• Pre-construction roof photos taken.
• Delivery inspected and any damage noted on the BOL. Packing slips filed.
• Storage is dry, off the ground and ventilated.
• Weather window checked (hail, storms, heat).
• Fall protection in place, and roof openings covered.

Install QA

• An approved pad is under every sleeper, and no sleeper is directly on the membrane.
• Sleepers are level and fully bearing, and drainage is unobstructed.
• Splices are installed at every joint, with all bolts torqued and marked.
• No unauthorized field cuts or drilling.
• Cable counts are within the run or hole counts, bend radii are respected, and runs are labeled.
• All covers and hold-down clamps are installed.
• Step-overs are at every crossing.
• The hood entry curb and flashing were done by the roofer of record, and firestopped if rated.
• Bonding and grounding are complete, tested, photographed before the covers go on, and recorded (grounding QA).
• Every joint and sleeper is photographed.

Closeout

• Roofer post-install inspection letter received.
• AHJ final inspection passed.
• As-builts delivered: route, sleepers, joints, entry and spare capacity.
• Warranty file delivered: ship dates, end dates, reseller invoice, the 30-day notice rule and the RMA process.
• Ownership-transfer notice sent to ANDREW within 15 days of turnover (why).
• O&M walk-down schedule given to the owner, including inspection after hail and wind.
• Tray added to the owner's property insurance schedule (hail and wind aren't warranty claims).
