02The Problem

Where great precon teams get blamed.

Your estimators are buried in 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.

Halozen starts where the estimate ends. The Obligation Matrix captures what the spec requires. The Risk Register scores what could hurt you. Per-sub packets get pricing right. Then every decision feeds the next project'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.

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.

Ask anything. Get a cited answer.

Bid Assist is the chat panel that's always on every project screen. It reads your live obligation register, your 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.
