1 · Series Circuits
| # | Circuit Name | Primary Cable Length (m) | Junction Boxes (blank = auto) | CCR |
|---|
Notes
One row per series circuit (removing a circuit also removes its schedule lines). Cable length is the total installed primary cable of the loop (out and back). Leave junction boxes blank to calculate them from the fixture count; choose "Existing" if the circuit already has a CCR with spare capacity.
2 · Fixture & Sign Schedule
| # | Circuit | Fixture / Sign Type | Qty |
|---|
Notes
One row per fixture or sign type on a circuit. Guidance signs and PAPI units are in the list as "structure" types (legs, base plate, foundation pad). For sign-level material detail use the Sign BOQ calculator; for PAPI use the PAPI BOQ calculator. CSV columns: circuit, type (id or name from the library below), qty. Circuits not yet defined are created with 0 m cable length — fill in the lengths afterwards.
3 · Fixture Library & Assumptions
Notes
Wattages and construction values below are typical starting values, not manufacturer data. Set them from your fixture datasheets and project specification.
Fixture & sign library (wattage, mounting, pad)
| Name | Mounting | Power (W) | Pad (m³ each) |
|---|
Inset = light base can in pavement. Elevated = frangible coupling and mounting base. Structure = legs, base plate and foundation pad (signs, PAPI units, masts). Pad volume is the concrete per fixture (0 for inset).

Add circuits and fixtures on the Calculate tab.
Material BOQ
Calculated / Nominal Quantity — not a Final BOQ Quantity. "Order qty" applies the allowance and rounds up to whole pieces. Verify against the approved layout drawing and project specification.
Per-Circuit Summary
How This Generator Works
The generator expands each schedule line by its fixture type, then adds per-circuit items (cable, junction boxes, CCR) and project-wide civil items. Everything comes from your inputs and the editable assumptions — nothing is hidden.
Per fixture
Each fixture or sign gets one series isolating transformer (45 / 65 / 100 / 150 / 200 / 300 / 500 W), primary and secondary connector sets, a secondary lead, an identification label, and a base or mounting set according to its mounting type. Spares are added to fixtures, transformers and connectors.
Bases and mounting
Inset: light base, mounting bolts, O-ring and spacer rings. Elevated: frangible coupling and mounting base. Structure: legs, couplings, base plate, anchor bolts and a foundation pad. Concrete is the pad volume per fixture times the quantity, with reinforcement per m³.
Cable, trench and junction boxes
Primary cable is each circuit's length plus the slack allowance. The trench assumes the out and back runs share it. Junction boxes use your entered number or the automatic ratio, each with an earth rod. Counterpoise follows the trench length.
CCR sizing per circuit
The smallest standard CCR (4 / 7.5 / 10 / 15 / 20 / 25 / 30 / 50 / 70 / 100 kW) at or above the requirement is listed for each circuit marked "New". Check the final design for voltage drop, insulation and CCR loading against the CCR Selection & Loading calculator.
What this generator does not do
It does not choose fixtures or spacing for you, derive quantities from runway geometry, or price the BOQ. It does not model switchgear, ALCMS, vault equipment, cable pits beyond junction boxes, or civil works other than the trench, sand bed, tape and foundation concrete. Add those items manually.
Using the results
Download the BOQ as CSV or copy it into Excel. Use Save Project to keep the circuits, schedule, library and assumptions in a file and reload them later.
