ISSUE 01 — SPEC ASSESSOR

Read a 700-page spec book in 28 minutes.

These three were buried in sections nobody had time to read.

$130K — BMS controls buried in Division 23

Three sentences in the mechanical section assigned all controls wiring to the electrical contractor. No line item in Division 26. No callout in the drawings. The estimator never opened Division 23 because it looked like a mechanical spec. The scope transfer was buried on page 287 of a 540-page book. The sub discovered it at the coordination meeting, two months after signing.

$147K — Crane and temp elevator power in General Conditions

Buried in the spec, not shown on a single drawing. The shop carried a token line item. Real number on a 14-month high-rise: $147K in feeders and disconnects. General Conditions Section 01 50 00 required the electrical sub to provide temporary power for construction cranes and temporary elevators, including feeders, disconnects, and coordination with the crane operator. None of it was on the electrical drawings.

$132K — Seismic bracing in the spec, not on the drawings

Required on all cable tray and conduit 2” and above. No detail on the plans. Inspector flagged it three months in. $132K in supports and rework. The spec called for seismic bracing on all distribution equipment, cable tray, and conduit 2” and above per the seismic design requirements in Division 26 05 00. The drawings showed none of it.

Picture a 14-story office build-out in a dense urban core. The spec book was 540 pages. The estimator had four days to price it with two other bids due the same week. The drawings were detailed, the fixture schedule was clean, and Division 26 was well organized. The estimator spent a full day on the takeoff and felt good about the number.

What the estimator didn’t have time to do was read Division 23 cover to cover. Three sentences on page 287 assigned “all temperature controls wiring, termination, and point-to-point verification for the building management system” to the electrical contractor. The mechanical drawings showed the BMS layout. The electrical drawings showed nothing. There was no line item in Division 26. There was no reference in the bid form. The only place this $130K scope existed in writing was in the mechanical specification.

The sub found out at the first coordination meeting. The mechanical contractor pointed to Section 23 09 00 and said the electrical sub owned the controls wiring. The PM went back to the spec and confirmed it. Three sentences. Page 287. $130K that wasn’t in the bid.

The estimator wasn’t careless. The estimator was doing the job the same way every estimator does it: read the electrical division, price the drawings, skim the rest if there’s time. On a week with three bids due, there wasn’t time. The spec book had the answer. The estimator just never got to that page.

THE PROMPT

Generate a one-page spec book review checklist for an electrical estimator bidding commercial construction projects. The checklist should be organized by spec division and cover the sections most likely to contain hidden electrical scope, unexpected obligations, or cost exposure. Include checkboxes next to each item so it can be printed and used as a manual reference while reading a spec book. Cover at minimum: Division 1 general conditions risk areas, Division 23 mechanical controls language, Division 26 electrical scope gaps, Division 27 communications responsibilities, Division 28 fire alarm termination and ownership, closeout and commissioning deliverables, temporary power and lighting obligations, BIM coordination requirements, seismic and structural support requirements, and schedule or liquidated damages language. Keep it to one printable page. No explanations, just the checklist items. Format it so an estimator can tape it to the wall next to their desk.
