The Division 08 / 28 seam checklist.
Twelve questions to ask of an electronic security bid package before you price it, drawn from the checks Blueprint runs. Division 08 says Division 28 owns it. Division 28 says Division 08 owns it. These are the questions that find that before bid.
The first five, in full
Each one names the rule family it comes from, so you can read the rule text and the cited authority yourself rather than take the question on trust.
-
For every controlled opening, which division carries the locking
device, and does the other division's section agree?
Four states cost money and only one of them is visible from inside your own section. Both divisions carry it, so it is priced twice or deleted twice. Neither carries it, so nobody has priced it. Each assigns it to the other, so both writers believed they had assigned the work rather than declined it. Or the documents do not settle it at all, which is a question, not an assumption.
Rules SB-020 to SB-023 -
Where a section says work is "by others", is the other named
anywhere in the documents?
A marker that moves work to another party without naming the party or the work tells every bidder that something here is not theirs, without telling them what. Every bidder draws the line in a different place and the low bidder is whoever drew it most generously. Quote the sentence back verbatim in the RFI. Paraphrasing it invites an answer to a question you did not ask.
Rule SB-001 -
Does any "by others" note hand the work to Division 28, which is
your own scope?
"BY OTHERS" reads as somebody else's problem right up until the sentence continues "BY DIV. 28". The door hardware supplier reads the same sentence, agrees the work is Division 28, and the common failure is symmetrical: neither party prices the rough-in. Confirm it is in the base bid rather than assumed to sit with the hardware supplier.
Rule SB-002 -
Where both divisions specify the locking device at one opening, do
they specify the same device?
An electrified lockset and an electric strike do not share a frame preparation. Only one device is installed, so one of the two sections is unmet the day the door is hung, and which one is decided by whoever ordered first rather than by the design. The exposure is the difference between the two products plus the preparation that suits only one of them.
Rule SB-020 -
On every egress opening carrying existing panic hardware, does the
specification resolve to electric latch retraction rather than a strike?
Where egress depends on a panic device the latch has to stay free at all times, so the locking function must act on the panic device itself and not on the frame. A strike named on that opening is not a substitution and it is not value engineering material. Acoustic preference in an adjacent classroom does not outrank free egress either.

The remaining seven
The questions are below. The formatted document adds the reasoning behind each one, the cited code or manufacturer authority, and a printable version you can run down with the package open.
- Does every latch retraction opening have its own dedicated sequenced supply, or is it fed from the shared access supply? Rule AC-021 · power and supply
- Is the access supply sized on total holding current with headroom plus the largest single inrush, and are standby batteries counted at two 12V units per 24VDC supply? Rule AC-022 · power and supply
- Which openings sit next to instruction or administration space, and does the supply calculation carry the quiet strike's higher holding current? Rule AC-012 · power and supply
- For every controlled opening, who carries the power and who carries the rough-in, answered separately from who carries the device? Rules SB-020 to SB-023 · rough-in responsibility
- Where rough-in or power is assigned to a third division, is that division actually named and is the circuit shown? Rule SB-023 · rough-in responsibility
- Does every controlled opening carry credential input, request to exit and a door position switch, or only a reader and a strike? Rule AC-001 · opening requirements
- For every aluminum storefront opening, do the documents state stile depth and door manufacturer, and is frame material stated on every other opening? Rules AC-013 and AC-014 · opening requirements
Every rule named above is published in full, with its conditions, its rationale and its cited authority.
