An estimator drafting a subcontract exhibit rarely works from one clean source. The current drawing set may be in Procore, Division 09 specs in the project manual, finish schedules on architectural sheets, and the latest addendum in an email attachment. Meanwhile, exclusions remain buried in subcontractor bid notes. Those sources have to be cross-referenced before anything can be priced, and when they are not reconciled, the scope carries missing or conflicting assignments. Scope gaps discovered late cause additional costs and delays.
An AI scope-of-work generator cross-checks the governing inputs, turns each requirement into a source-backed trade row, and routes unresolved assignments for estimator review. It can define responsibilities, deliverables, and timelines while preserving the sheet, detail, schedule, spec paragraph, addendum, or bid note behind each inclusion. For built-world teams, AI agents can ingest project files across the scattered systems where those inputs reside. This page walks the generator end-to-end: what goes in, what comes out, a worked Division 09 package, and the exceptions an estimator still has to resolve before issue.
Generate a Construction Scope
Configure a custom construction scope generation workflow using the project files and review controls needed for the selected trade.
Configure the Inputs
Define what the workflow will review and how it will structure the output:
Upload: The current drawing set, applicable spec sections, schedules, addenda, bid instructions, subcontractor proposal, and your company scope template.
Select: The trade package, governing revisions, output structure, and required source-reference fields.
After setting these boundaries, generate the source-backed rows.
Generate Source-Backed Rows
Set the workflow to produce reviewable scope requirements. Require every generated inclusion to point back to the project file that supports it, and route anything unresolved for estimator approval.
Generate: Draft candidate CSI-aligned scope rows covering labor, materials, equipment, deliverables, trade interfaces, exclusions, qualifications, and unresolved review items.
Output preview:
Requirement: Furnish and install gypsum board assemblies indicated by the current wall-type legend and referenced details.
Responsible trade: Drywall.
Source: Applicable sheet, detail, schedule, or spec paragraph.
Status: The project team must review whether no trade has accepted responsibility for backing.
The estimator should resolve each review-required status before issuing the scope.
Establish the Governing Bid Package
Use this stage when drawings, specs, schedules, and addenda may not share the same revision basis or trade boundary. Datagrid's AI agents compare revisions and extract requirements. They also route unresolved trade assignments for estimator review. Estimators remain responsible for trade boundaries and pricing decisions, including exceptions.
1. Upload the Current Drawing Set and Trade Specs
Start by defining the project files that govern the scope. Include the current drawing set, relevant CSI specification sections, drawing and finish schedules, addenda, bid instructions, owner requirements, accepted alternates, and the project schedule. If the scope will become a subcontract exhibit, include the contract form and company scope template as well.
We treat revision control as the first confidence test. Confirm that the drawing set contains no superseded plans, and acknowledge every addendum before extraction. When an addendum changes sheets after the first scope draft, the Document Comparison Agent compares drawing sets. It identifies material changes, scope creep, and project risk that require a revised scope row. Its results depend on correct sheet pairing and revision metadata, so confirm that both drawing sets are complete and labeled correctly before accepting a flagged change.
2. Identify Applicable Sheets, Details, and Sections
Next, the AI agents locate the sources that apply to the selected trade. For a drywall package, that can include wall-type legends, floor plans, reflected ceiling plans, interior elevations, finish schedules, rated assembly details, and the applicable Division 09 sections.
The Deep Search Agent searches across drawings, specs, RFIs, and submittals and retrieves requirements grounded in project files. Keep the extraction selective so that the relationships among a plan note, its detail callout, and the corresponding execution requirement remain visible. Before running cross-project-file search, upload or connect every governing addendum, alternate, and bidder qualification.
Extract and Structure Trade Requirements
Use this stage after the project team confirms the governing sources and the package needs discrete, reviewable assignments.
3. Extract Materials, Responsibilities, and Deliverables
Once the project team identifies the governing sources, AI agents analyze text and tables in the context of visual layout. Reading a construction document is inherently multimodal because a plan note means one thing in the context of its detail callout and another on its own. The extraction should separate four different scope questions:
What labor, materials, equipment, supervision, and services are required?
Where does the work occur, and which drawing details govern it?
Which submittals, samples, testing, closeout items, or coordination duties are required?
Which responsibilities sit at the interface with another trade?
"Provide drywall per plans and specs" leaves unresolved whether the package includes framing, backing, insulation, access-panel coordination, fire-rated assemblies, sealants, protection, or patching. The workflow should draft those requirements as separate, reviewable rows.
4. Generate CSI-Aligned Scope Line Items
The draft should organize work using the project's bid-package structure and the relevant CSI MasterFormat sections. Each candidate line item should include the requirement, responsible trade, source reference, status, and any unresolved qualification.
A practical generated scope typically contains:
Governing drawings, specification sections, addenda, and alternates
Labor, material, equipment, supervision, and delivery responsibilities
Trade-specific inclusions organized as discrete scope rows
Submittals, samples, mockups, testing, and closeout deliverables
Coordination requirements and interfaces with adjacent trades
Temporary facilities, access, protection, cleanup, and schedule constraints
Allowances, unit prices, alternates, exclusions, qualifications, and assumptions
Source references and open review items for every unresolved conflict
Precise scope descriptions matter. Subcontract instructions call for references to drawings, specification sections, addenda, modifications, and accepted alternates. They also call for work that is specifically excluded. The AIA A401 instructions reflect those expectations.
Resolve Exceptions and Approve the Scope
Use this stage when package assignments conflict, source requirements are incomplete, or the draft is ready for commercial and contractual approval.
5. Flag Conflicts, Gaps, and Overlaps
Run scope checking before bid leveling when subcontractor exclusions do not align or two packages appear to carry the same work. The Scope Checker Agent reconciles contracts, drawings, and project metadata, flagging scope gaps and overlaps before they become disputes. Treat flagged overlaps as review items when the responsibility matrix is outdated or package naming is inconsistent. Confirm each proposed assignment against the current bid structure.
The workflow should distinguish between missing information and conflicting information. A requirement shown on drawings but absent from the specs is different from a responsibility assigned to both electrical and mechanical. Both need attention, but the project team will resolve them differently through a clarification, an RFI, a revised bid instruction, or an explicit scope assignment.
6. Approve and Hand Off the Scope
The final step belongs to an estimator, project manager, preconstruction leader, or contract reviewer. The operator confirms quantities, trade boundaries, commercial terms, and legal language before issuing the scope. After approval, the project team can hand off the structured scope to downstream workflows for bid management, project management, collaboration, or finance. Preserve the source references and approval history so later reviewers can see which project files informed each line item and which qualifications the project team accepted.
Worked Example: Division 09 Gypsum Board Scope
Use a worked trade package to test whether the custom workflow produces actionable scope rows. Division 09 gypsum board is a useful test because requirements can be distributed across wall types, reflected ceiling plans, finish schedules, rated details, and several specification sections.
Inputs for the Trade Package
The project team supplies the current architectural drawing set, wall-type legend, reflected ceiling plans, finish schedule, interior elevations, applicable Division 09 sections, addenda, alternates, milestone schedule, and the drywall bidder's proposal. The workflow also receives the company's standard scope template and responsibility matrix.
Generated Scope Rows
The draft separates the package into rows such as:
Furnish and install gypsum board assemblies indicated by the current wall-type legend and referenced details.
Include required metal framing, board types, thicknesses, layers, fasteners, accessories, and finishes identified in the applicable specs and schedules.
Identify rated, moisture-resistant, impact-resistant, shaft-wall, or other special assemblies as required by the governing project files.
Coordinate framing and board installation with above-ceiling MEP work, access panels, openings, backing, penetrations, and scheduled inspections.
Provide required submittals, product data, samples, mockups, testing documentation, attic stock, and closeout materials.
Carry protection, patching, cleanup, delivery constraints, and phased installation requirements assigned to the package.
We treat ambiguous backing responsibility as an early test of whether the generator is producing reliable assignments. If backing appears in a detail and the project team has not assigned responsibility, the output should flag the interface for assignment to the project team.
Exceptions Raised for Approval
The generated draft should call attention to conflicts between wall types and plans, revised ceiling details, inconsistencies in the finish schedule, and a missing addendum acknowledgment. It should also flag ambiguous backing responsibility, unassigned firestopping, allowances for owner-selected finishes, and exclusions in the bidder's proposal. These are bid decisions. The AI agents surface them, but the estimator and project team must decide how to assign and price the work.
Human Review Checklist Before Issue
Use this checklist before a generated scope becomes a bid package, leveling baseline, or subcontract exhibit. Human review remains essential because agentic AI cannot determine unseen field conditions, negotiate risk, or make final code and contract judgments.
Verify Governing Project Files
Confirm every drawing carries the current revision status, and acknowledge all issued addenda and accepted alternates.
Reconcile drawing notes, schedules, details, and specification requirements.
Resolve any revision discrepancy before reviewing commercial and trade boundaries.
Resolve Commercial and Trade Boundaries
Resolve scope splits and physical interfaces between trades.
Review exclusions, qualifications, assumptions, and "by others" language.
Confirm allowances, unit prices, owner-furnished equipment, and owner-installed items.
Assign temporary facilities, access, protection, cleanup, hoisting, and scaffolding.
Validate extracted dimensions, counts, areas, and other quantities.
Check procurement dates, phasing, work hours, shutdowns, and schedule constraints.
Route code interpretations and design judgments to qualified professionals.
Account for field verification, concealed conditions, and existing construction.
Confirm submittals, testing, warranties, training, attic stock, and closeout duties.
Record each approved assignment and exception before issue.
Record Approval and Exceptions
Record who reviewed the generated scope and which changes were accepted or rejected.
Apply additional manual review to low-quality scans and incomplete drawing sets, especially those with hand markings or nonstandard symbols. Contract clauses and risk-shifting language also require qualified legal or commercial judgment. Higher-risk applications need documented human review, tracking, and management oversight, and a generated scope that becomes a subcontract exhibit sits in that category.
Measure Scope Quality With Construction Metrics
Track whether scope generation improves preconstruction performance. Useful measures include:
Review time per trade package
Generated line items with valid source references
Unresolved drawing-and-spec conflicts at issue
Addenda incorporated into each package
Scope exclusions and overlaps identified before award
Bid clarification requests required during leveling
Scope rows changed during final subcontract negotiation
Post-award changes tied to omitted or ambiguous scope
Review these measures by trade package and investigate any rise in unresolved conflicts or post-award changes.
Connect Scope Generation to the Project Stack
Use integrations when the governing project files and downstream approvals span multiple systems. Define the system of record and required handoff fields for each part of the workflow:
Project management and project files: Transfer current drawings, addenda, revision metadata, package identifiers, source-reference fields, and approval status from Procore or Autodesk Construction Cloud.
Scheduling: Connect milestone dates, phasing requirements, shutdowns, and schedule constraints from P6 EPPM or Oracle Primavera Cloud.
BIM and model coordination: Connect applicable Revit models and coordination findings from Navisworks, Revizto, or SYNCHRO 4D Pro to the relevant package identifier.
Estimating and bidding: Route trade-package scope rows, bidder qualifications, exclusions, and approval status to BuildingConnected or Accubid Anywhere.
ERP and financial systems: Carry awarded package identifiers, approved allowances, unit prices, commitments, and cost codes into Sage 300 Cloud or Viewpoint Vista.
Collaboration: Route unresolved assignments and approval requests to the responsible project team in Microsoft Teams.
Integration controls the handoff so current drawings feed the scope workflow and approved rows reach the appropriate project team. Later revisions should trigger comparison and review while preserving the basis of the issued scope.
Review Your Next Trade Scope
