Every answer cites its source.
Three jobs construction project managers work through every week. In each one, Knittrix answers a plain-English question with the spec, drawing, or contract passage that backs it up — and the page number that proves it.
01 · RFI prep
Confirm what the spec already says before sending the RFI.
A PM is standing at a partition layout review on a Tuesday morning. The framer asks whether the firestop at the corridor needs to be 1-hour or 2-hour rated. The spec is 312 pages. Logging an RFI takes a day, costs goodwill with the architect, and waiting stalls the framing crew. Most RFIs that get sent are already answered by the spec — the question is just where.
— What's the fire-rating requirement for the corridor partitions on level 2?
The spec requires 1-hour rated firestopping at corridor partitions in occupancy type B [07 84 13 · 2.3 · p. 47]. Level 2 is classified as occupancy type B in the code summary on sheet G-001 [G-001 · Code Summary · p. 1], so the 1-hour requirement applies.
The PM clicks through to page 47 and reads the section in context. The answer matches. They tell the framer 1-hour, the framer goes back to the wall, and the RFI is never logged.
02 · Submittal review
Match the submittal against what the spec actually requires.
A submittal package arrives for ceramic floor tile in the lobby. Before approving it and shipping it back to the architect, the PM needs to confirm the submitted product matches the spec — thickness, slip resistance, and fire rating. The relevant spec section is fourteen pages of technical detail buried inside a 280-page specification book.
— What does the spec require for ceramic tile in the lobby — thickness, slip rating, and fire rating?
Section 09 30 00 requires porcelain floor tile with a minimum thickness of 8mm, a coefficient of friction (DCOF) of at least 0.42 per ANSI A137.1, and a Class A flame spread rating per ASTM E84 [09 30 00 · 2.3 · p. 49].
The PM compares the submitted cut sheet against the three requirements. Two match, one is below. They mark the submittal Revise and Resubmit with the specific clause cited. The sub knows exactly what to fix.
03 · Payment app inputs
Pull the contract terms that drive the pay app — without flipping pages.
It's the second of the month. The PM is preparing the monthly payment application in Sage. Before they fill it out they need four contract terms — original contract sum, retainage rate, substantial completion date (which governs whether retainage drops), and LD rate per day if they slip. All four live somewhere in the 240-page A101 + A201 contract package.
— What's the contract sum, retainage rate, substantial completion date, and LD rate per day?
The contract sum is $4,237,500.00 [A101 Article 4 · p. 3]. Retainage is 10% on completed work [A201 § 9.6.1 · Progress Payments · p. 38]. Substantial completion is March 15, 2026 [A101 Article 3 · p. 2]. Liquidated damages are $2,500 per calendar day after substantial completion [A101 Supplementary Conditions · p. 18].
The PM fills the four numbers into Sage in under a minute. They flag the retainage drop date on their calendar and forward the LD clause to the schedule lead. The contract package goes back on the shelf.
