Review-first estimate

Creek Park Subdivision — source-linked breakdown

Every line item below points back to the drawing or spec it came from, declares a confidence band, and flags what still needs your review. Diffs show the correction an estimator made after sanity-checking the prediction. None of this numbers magic comes from us — it comes from the extraction trail, the reviewer, and the spec.

BuildBid intentionally did not infer this

Bypass pumping during MH-12 replacement

Spec section 02 31 23 references a bypass plan but the mainline profile on C-301 does not show existing service to be kept in operation. Flow rates and duration are estimator judgement calls — BuildBid intentionally left this blank rather than guess.

Suggested scope to add manually: Add 1 LS bypass pumping (4" pumps + hose + fuel + monitoring) once estimator confirms active sewer tie-in staging.

Measurement basis

Aggregated from profile callouts on sheet C-301; depth band split inferred from invert elevations at MH-12 through MH-16.

Needs estimator check because…

Depth band 10-12' boundary depends on finished grade at STA 21+50, which is shown on civil C-102 but not cross-referenced on the profile. Verify before bidding deeper trench rate.
