CONSTRUCTION

While preconstruction documents tell you what to build and how much it should cost, construction phase documents track what is actually happening on site, what has been changed, and what needs to be paid for.

Here is a breakdown of the essential documents required during the active construction phase, categorized by their function:

1. Contract Administration & Management

These documents govern the relationship between the owner, architect, and contractor during the build.

Owner-Contractor Agreement: The signed contract (e.g., Lump Sum, Cost-Plus) that includes general conditions and requirements.
Certificate of Insurance: Proof that the contractor and all subcontractors maintain the required liability and workers' compensation insurance throughout the project.
Performance and Payment Bonds: Surety bonds that protect the owner if the contractor fails to perform (performance) or fails to pay subcontractors/suppliers (payment).
Schedule of Values: A detailed breakdown of the total contract price, allocating a value to each major task . This is used to process progress payments based on payment structure agreed upon.

2. Logistical & Safety Documentation

These are required before any physical work can begin on site and must be maintained daily.

Site Safety Plan: Outlines specific safety protocols, hazard communication, emergency procedures, and PPE requirements for that specific jobsite.
Notices of Commencement/Completion: Legal notices filed with local government to establish the official start and end of the project for lien purposes.
Site Logistics Plan: A diagram showing where materials will be stored, where cranes will sit, trailer placement, and site access routes.

3. Quality Assurance & Progress Tracking

This is the "proof" that the work was done correctly and according to the approved plans.

RFIs (Requests for Information): Formal questions from the contractor to the design team when plans are unclear, conflicting, or missing. The response becomes a binding instruction.
Submittals: Samples, shop drawings (e.g., detailed fabrication diagrams for steel beams), product data sheets, and mock-ups that the contractor submits to the architect for approval before purchasing or installing the items.
Meeting Minutes: Official records of progress meetings, noting decisions made, action items, and who is responsible for them.
Daily Logs/Reports: A diary kept by the site superintendent noting weather conditions, workforce count, equipment on site, work completed, and any visitors or incidents.
Test Reports: Documentation of required tests, such as concrete cylinder break tests, soil compaction tests, or weld inspections.

4. Change Management

Rarely does a project proceed exactly as drawn. These documents handle deviations.

Change Orders: A written document that modifies the original contract. It changes the scope of work, the contract sum, and/or the contract time. It must be signed by both the owner and contractor to be valid.
Construction Change Directive (CCD): Used when the owner and contractor agree a change is needed but haven't yet agreed on the price or time impact. It authorizes the work to proceed while negotiations continue, preventing delays.

5. Financial & Payment Documents

These ensure the flow of money matches the flow of work.

Application for Payment (Pay Application): A document submitted by the contractor (usually monthly) requesting payment for work completed during that period, based on the Schedule of Values.
Lean Lien Waivers: Signed by contractors and subcontractors when they get paid, releasing their right to file a lien against the property for that amount.
Back Charges: Invoices issued by a general contractor to a subcontractor for costs incurred due to the sub's faulty work, cleanup needs, or delays.

6. As-Built Documentation

These documents capture the "real world" changes made during construction.

As-Built (or Record) Drawings: The original construction drawings are marked up by the contractor to show any deviations, field changes, or hidden conditions (like a pipe that had to be moved 6 inches to avoid a rock). These are crucial for future renovations or maintenance.
