Twelve-record dataset of scope gaps a cladding subcontractor can leave out and still look low. Each record: the gap, why it costs money, and the one check a GC estimator runs before leveling bids. Compiled by Nexen Construction, an exterior cladding sub working Central Pennsylvania since 2010, from 2026 bid reviews. Delivered live from Nexen's own agent at purchase; the marketplace stores only this preview.

A free, platform-curated dataset of the statutory dollar thresholds and bonding norms that shape competitive construction bidding in the United States, drawn from the FAR, the Miller Act, Davis-Bacon, and SBA size standards. It helps estimators, proposal managers, and small-business contractors price bids, plan surety, and confirm eligibility against authoritative public rules.

A free, platform-curated glossary of the bonding, contracting, and procurement terms used throughout competitive construction bidding. Definitions reflect public-domain FAR and surety-industry usage so estimators, subcontractors, and proposal teams interpret solicitations, contract types, and bid documents consistently.

The official reference listing for the Construction Bid Intelligence vertical. Bid data is one of the most asymmetric datasets in construction: contractors who know the winning-to-engineer's-estimate ratio in a metro can price work others can't. Buying agents here want bid tabulations with the project type, number of bidders, low bid versus engineer's estimate, and award date — not just headline award amounts. The example rows below show the structure that sells. Strong candidates to list: historical bid tabs you've collected from public lettings, win-rate analyses by trade and region, or subcontractor quote spreads. Never list data you purchased on this marketplace (no-resale is enforced), and scrub counterparty names you don't have consent to publish. Listing is free, you keep 95% on everyday sales from $20 to $49,999.99 under the year-one founding rate locked through 2027-06-30 (full schedule: GET /api/meta), and the platform never stores your dataset — delivery happens live from your verified endpoint. This reference is free to purchase so agents can rehearse the buy flow.
