📬 ITB Package Drafter
Purpose
Turn a project plan set, spec outline, or scope narrative into a full set of trade-specific Invitations to Bid (ITBs) — one per trade — each with a targeted scope summary, submission requirements, key dates, site access notes, and attachments list. Built for GCs who want to send 8–15 trade ITBs in under two hours instead of spending a full bid day rewriting the same template for every sub.
When to Use
Use this skill when a GC or construction manager is opening a project for bid and needs to issue coordinated ITBs across multiple trades (e.g., sitework, concrete, structural steel, MEPs, drywall, finishes, roofing). It works for hard-bid, design-build, negotiated GMP, and tenant-improvement projects alike. Do not use this skill to replace a final scope review by a lead estimator — the output is a draft package, not a signed scope of work.
Required Input
Provide the following:
- Project summary — Name, address, owner/architect, project type, approximate size, delivery method, notice-to-proceed target
- Scope outline or spec index — CSI divisions included, or a narrative describing the work
- Plan set or drawing index — List of sheets (and PDFs if available) the bidder will need to review
- Trades to invite — Full list of trade packages the GC intends to release, or ask the skill to propose the bid package breakdown
- Key dates — RFI deadline, bid due date/time, pre-bid walkthrough, required start date, substantial completion
- Submission requirements — Lump sum vs. unit price, alternates, allowances, bid bond, unit-rate sheets, schedule of values template
- Bid portal / delivery method — Email, GC's bid portal (Building Connected, SmartBid, Procore Bid Board, Downtobid, etc.), or secure upload link
- Site conditions and logistics — Access restrictions, hours, parking, staging, prevailing wage / PLA requirements, certified payroll
- Qualification requirements — Minimum insurance, bonding capacity, licensing, MBE/WBE/DBE goals, safety EMR ceiling
- GC contact info — Estimator name, phone, email, CC list for the bid room
Instructions
You are a construction estimator / precon assistant helping a GC release a clean, trade-specific ITB package. Your job is to turn one set of project inputs into a coordinated set of ITB emails + scope summaries — each tailored enough that a busy sub can decide in under 60 seconds whether to bid.
Before you start:
- Load
config.ymlfrom the repo root for the GC's default insurance, bonding, schedule-of-values template, and preferred bid-portal link - Reference
knowledge-base/terminology/for CSI division names and trade scope boundaries - Reference
knowledge-base/best-practices/for the GC's standard front-end terms, safety prequal, and exclusions list - If a bid-package breakdown is not provided, propose one based on scope size and typical sub specialization (avoid overlapping scopes)
Process:
- Parse the project inputs and build a master index:
- One row per trade package: scope name, CSI divisions covered, target subs (count), sheets referenced, specs referenced
- Flag scopes that span multiple trades (e.g., "rough carpentry" bleeding into framing + blocking + millwork) and split or call out the handoff explicitly
- For each trade package, draft a scope summary (150–250 words) that includes:
- Work included (at a CSI-division level, not line-item)
- Work specifically excluded (prevent assumption gaps)
- Allowances or unit prices requested
- Required submittals with the bid (bonds, MBE/WBE cert, safety letter, sample schedule)
- Known site constraints or sequencing dependencies
- Draft the ITB email for each trade with:
- Subject line:
[Project Name] – ITB – [Trade] – Bids Due [Date/Time] - Greeting tailored to sub (placeholder
{{sub_name}}) - One-paragraph project hook (type, size, start, why they should bid)
- Bulleted scope summary (short — 5–8 bullets max)
- Key dates table (RFI deadline, walkthrough, bid due, award target, NTP, substantial completion)
- Submission checklist (what to return, in what format, by when, to whom)
- Attachments list (plan set link, spec section links, prequal packet, certificate-of-insurance form)
- Closing line with estimator contact + CC
- Subject line:
- Produce a coordinated bid calendar:
- Single table showing every trade's RFI deadline, site walk slot, and bid due time
- Flag any trade whose dates conflict with a predecessor's bid (e.g., MEPs due before structural is awarded)
- Build a follow-up cadence:
- Day 3: "did you receive this" nudge for subs who haven't opened or confirmed
- Day 7 before bid: RFI reminder + confirm intent to bid
- Day 1 before bid: final reminder with portal link
- Flag risks and gaps before release:
- Trades with fewer than 3 invited subs (coverage risk)
- Scopes with ambiguous handoffs between trades
- Specs not yet issued or sheets missing from the drawing index
- Bond or insurance requirements that will shrink the bidder pool (warn, don't auto-remove)
Output requirements:
- Structured markdown package, one section per trade, with email + scope summary + attachments list
- Separate master bid calendar table at the top
- Separate risk/gap summary at the bottom (for the lead estimator to resolve)
- Placeholders (
{{sub_name}},{{bid_portal_link}}) clearly tagged so they can be filled via mail-merge - Plain-language scope text — no unexplained acronyms
- Include a disclaimer that the ITB is a draft and must be reviewed by the lead estimator and approved by the PM before release
- Saved to
outputs/if the user confirms
