02The Problem

Where great precon teams take the blame.

Your estimators are buried under 600-page specs, cross-referencing addenda against general requirements in spreadsheets. Your subs are quoting against incomplete scope. And when a $140K scope gap surfaces post-award, everyone points fingers at preconstruction.

NOTE 01

Static Checklists

Today's tools extract obligations into flat lists. They don't reason about conflicts between specs, addenda, and sub-scopes.

NOTE 02

Siloed Documents

Addenda contradict general requirements. MEPs conflict with structural specs. Nobody catches it until the field does.

NOTE 03

No Audit Trail

When the change order hits, you can't trace the decision. When closeout comes, you can't defend the claim.

03The 4-Step Workflow

Read. Assess. Export. Analyze.

By the time the estimator opens the matrix, the spec's already mapped. The Obligation Matrix shows what's required. The Risk Register scores what could hurt you. Per-sub packets get pricing right. Every decision feeds the next bid's institutional memory.

◆ 4 StepEstimate → Award
01READ THE SPEC
Artifact · Obligation Matrix

Every requirement, cited.

Tender docs in. Contract, addenda, geotech, drawings. AI parses everything and populates the Live Obligation Matrix — every requirement mapped to its source clause and page. CSI-classified during project setup. Conflicts between divisions flagged before the drawing set opens.

Estimator opens the matrix already populated. No spec re-reading.
02ASSESS & SCORE
Artifact · Risk Register

What could hurt you.

The Risk Register builds on the obligation matrix. Impact and likelihood scoring, dollar exposure with reasoning shown, ownership assignment, mitigation actions. Cross-trade conflict and overlap detection as a first-class signal. New addenda flag modified rows on both surfaces. Nothing hides until the field finds it.

Exec sees what could hurt and how bad. Go/no-go is informed.
03EXPORT TO SUBS
Artifact · Per-Sub Obligation Packets

Subs price the right scope.

Per-sub obligation packets filtered by CSI division. Excel or Word. Cited to section and page. Attaches to the bid package the GC already sends. Halozen produces the obligations exhibit; the GC keeps owning the bid package.

Subs price against your obligations, not their interpretation.
04ANALYZE & CLOSE LOOP
Artifact · Sub Gap Analysis + Reasoning Ledger

The loop closes.

Sub quotes uploaded and tagged. Per-obligation gap analysis: covered, partially covered, not covered, clarification needed. Every decision captured in the Reasoning Ledger. The Risk Register feeds institutional memory — which sharpens Step 1 on the next bid.

Next bid starts smarter than this one.

AG-06Bid Assist

Ask anything. Get a cited answer.

The questions your team actually asks — answered from your spec, your ledger, your past bids.

Bid Assist is the chat panel that's always on every project screen. It pulls from the live obligation register, the reasoning ledger, and your firm's history of past bids. Every answer cites its source. Pulls up before the bid for research, during the bid for sub coordination, and after award when a change order needs defending. One assistant, every phase.
