How to manage contracts for construction companies

On a Tuesday site walk, the owner's representative asks a mechanical subcontractor to reroute a duct run around a new beam. The foreman agrees on the spot. Nobody writes it down. Three weeks later the subcontractor bills the extra labor, and the general contractor has no signed change order to pass up to the owner. The work was real. The paper trail was missing.

Managing contracts in a construction company means running one system across every project. Keep each prime contract, subcontract, supply order, and change order in one register. Capture the same fields for each. Let notice deadlines drive reminders, and give each contract a named owner. This guide covers United States (US) construction practice, with the federal Miller Act and the Federal Acquisition Regulation (FAR) as worked legal examples. It is general information, not legal advice.

Purpose and timing

Contract work is part of the construction manager's core job. The Occupational Information Network (O*NET) is the US occupational database. It lists preparing contracts as a core task for construction managers, along with negotiating revisions with architects, consultants, clients, suppliers, or subcontractors [1]. It also lists interpreting and explaining plans and contract terms to the owner's representatives, workers, and clients [1].

That work multiplies with every job. One project can carry a prime contract, a dozen subcontracts, supply and equipment rental agreements, and bonds. Each document can set its own dates. Payment applications, change requests, notices, and warranty periods may all run on different clocks. If you want a refresher on how these agreements are priced and structured, read what a construction contract is.

The timing matters most at three points:

• At award. This is when you set up the record, before work starts and terms get forgotten.
• When scope changes. Check whether your change clause requires written notice and sets a deadline. If it does, record that deadline and meet it.
• At closeout. Check which payments and periods your contracts tie to completion, such as retainage release or warranty start. Record those dates when they happen.

Start the process at award. Fixing a register in the middle of a dispute is much harder.

What information to capture before starting

Before you build anything, agree on what a complete contract record looks like. Use the same fields for every contract on every project. That is what lets you sort, filter, and answer questions across the whole company.

Field	Why it matters
Project and contract type	Prime contract, subcontract, supply order, rental, or bond
Counterparty and notice address	The contract may name where and how notices must be sent
Contract value and pricing basis	Lump sum, unit price, or cost plus fee changes how you track cost
Payment terms and retainage	Pay application dates, payment periods, and release conditions
Change order procedure	Who can order a change, in what form, and the notice deadline
Key dates	Start, milestones, substantial completion, and final completion
Insurance and bond dates	The dates to check against any coverage the contract requires
Flow-down terms	Prime contract duties that must pass to each subcontractor
Internal owner	The person responsible for the next decision on this contract

Then collect the full document chain. Check which drawings, specifications, and schedules each contract incorporates, and add every signed change order. A register built only from the signed base agreement misses every later change.

Agree on roles at this stage too. Someone in the office owns the register. The project manager owns decisions on each contract. Site staff need one clear way to report instructions that might change scope.

Step-by-step workflow

Run the same sequence on every project.

1. Collect every signed document at award, including exhibits, schedules, and bonds.
2. Classify each document by project and contract type.
3. Extract the fields above into the register, with a link back to the source file.
4. Assign a named owner and a backup to each contract.
5. Log every scope instruction and change order the day it happens.
6. Review upcoming deadlines on a fixed cadence, and record each decision.

Start with one project. Prove the process there, then roll it out to the next job.

Subcontracts and flow-down terms

For each subcontract, record the scope, the price, the payment terms, and the retainage rate. Then check which duties the prime contract requires you to pass down to the subcontractor. Look at notice periods, insurance levels, and schedule duties first.

Mismatched notice periods create real gaps. Say the owner gives you a set number of days to claim a change. If your subcontract gives the subcontractor longer to notify you, its claim can arrive after your own deadline has passed. Record both periods side by side.

Change orders and scope notices

Track each change order as its own record, linked to the parent contract. Record who ordered it, when, in what form, and when notice was given.

US federal construction contracts show how strict a change clause can be. Under FAR 43.205(d), federal contracting officers insert the Changes clause at FAR 52.243-4 in fixed-price construction contracts expected to exceed the simplified acquisition threshold [4]. Under FAR 52.243-4, not every order arrives as a formal written change order [4]. Under that FAR clause, a written or oral order from the contracting officer that causes a change counts as a change order only if the contractor gives the contracting officer written notice [4]. Under FAR 52.243-4, that notice must state the date, circumstances, and source of the order. The FAR clause also requires the notice to say that the contractor regards the order as a change order [4].

FAR 52.243-4 sets more limits. Under FAR 52.243-4, costs for such a change incurred more than 20 days before the written notice are not recoverable, except for defective specifications [4]. Under FAR 52.243-4, the contractor must also assert its right to an adjustment within 30 days, unless the government extends that period [4]. Under the FAR clause, that period runs from receipt of a written change order, or from the contractor's own written notice [4]. FAR 52.243-4 requires the assertion as a written statement to the contracting officer, describing the general nature and amount of the proposal [4]. The FAR prescription for that clause lets agencies vary the 30-day period under their own procedures [4]. Under FAR 52.243-4, no adjustment proposal is allowed if asserted after final payment [4].

Other contracts set their own change procedures. Read the change clause in each contract and put its deadlines in the register. The free construction contract review tool analyzes one uploaded contract, including its change-order process, payment schedule and retainage, and delay terms [6].

Payment terms, retainage, and bonds

Record when each pay application is due, how long the payer has to pay, and what triggers retainage release. These dates drive cash flow, so give them owners and reminders.

Bonds need the same attention. The federal Miller Act covers US federal contracts of more than $100,000 for the construction, alteration, or repair of a public building or public work [2]. Under the Miller Act, the contractor must furnish a performance bond and a payment bond before such a contract is awarded [2]. Under the Miller Act, a contracting officer may waive both bonds for work performed in a foreign country, if furnishing them is impracticable [2].

The Miller Act also sets deadlines for unpaid parties on bonded federal jobs. Take a person who furnished labor or material on such a job and was not paid in full. Under the Miller Act, they may sue on the payment bond once 90 days have passed since their last labor or material [3]. Some claimants contracted only with a subcontractor, not with the prime contractor. Under the Miller Act, they may sue only after giving the prime contractor written notice within 90 days of their last labor or material [3]. Under the Miller Act, the claim must state, with substantial accuracy, the amount claimed and the name of the party supplied or worked for [3]. Under the Miller Act, that notice must be served in one of two ways [3]:

• by any means that gives written third-party verification of delivery to the prime contractor, at any place it keeps an office or does business, or at its residence
• in any manner in which the US marshal for the district where the project is located may serve a summons

Under the Miller Act, any such suit must be brought within one year of the claimant's last labor or material [3].

The Miller Act applies to federal work. For state and private projects, check the bond, lien, and payment rules that apply where each project sits.

Renewals and recurring agreements

Not every construction contract ends with the project. Check equipment rentals, yard leases, software subscriptions, and supplier master agreements for automatic renewal terms. Track their notice deadlines the way you would for any vendor. The guides on how to manage vendor contracts and how to manage contract renewals cover that side in detail.

Common failure modes

Verbal instructions with no written follow-up. A site agreement that never becomes a written notice leaves no record of the change. On US federal jobs under FAR 52.243-4, recovery for an order that is not a formal change order depends on written notice [4].

Notice periods that do not line up. If a subcontractor's claim window runs longer than yours, its claim can reach you after your own deadline. Compare the two periods before work starts.

Reminders tied to the end date. If a contract requires notice before its end date, the end date alert comes too late. Alert on the notice date.

One person holds every date. A single coordinator tracking every project is a point of failure. Assign an owner and a backup to each contract.

Site copies drift from the master file. A change order signed in the field may never reach the office. Make every signed document flow to one place.

Insurance and bond dates go unchecked. Record the policy and expiry dates shown on each insurance certificate and bond. Before a date arrives, check that any coverage the contract requires is still in place, and ask for updated evidence.

Closeout dates are not recorded. If your contracts tie retainage release or warranty periods to completion, those dates control when money and rights move. Record them when they happen.

These are forms of contract risk. The contract risk management glossary entry explains the wider discipline.

Practical checklist

Use this list as the standing definition of a project with contracts under control.

• Every prime contract, subcontract, supply order, rental, and bond sits in one register, tagged by project
• Each record is built from the full document chain, including signed change orders
• Payment application dates, payment periods, and retainage release conditions are recorded
• The change order procedure and notice deadline are recorded for each contract
• Prime contract notice periods are compared with each subcontract's notice periods
• Every scope instruction from the field is logged in writing the same day
• Insurance certificate and bond expiry dates are tracked
• Every contract has a named owner and a backup
• Recurring agreements have their renewal notice deadlines diarized
• Substantial completion and final completion dates are recorded when they happen
• The register is reviewed on a fixed cadence, such as weekly during active work

Where software helps

A spreadsheet can hold a register. Test it against the jobs above. Does each notice deadline reach a named person in time? Can a project manager find the current signed version of a subcontract from the site? Can you see every open change order across all projects? Where the answer is no, a dedicated tool helps.

Look for a few plain capabilities. You need one searchable store for contracts and related files. You need extraction that turns contract text into fields, and reminders that attach to notice dates and reach named people. Company-wide reporting matters too. The guides to contract management software for construction and the construction contract management software buyer's guide compare options in more depth.

Contracko covers that work. Its contract repository stores contracts and related files, including Portable Document Format (PDF) files and scans, with contract types, metadata, and search [5]. Contract data extraction uses artificial intelligence (AI) to pull dates, parties, values, notice periods, and custom fields from uploaded documents [5]. Expiration reminders track renewal dates, end dates, notice dates, and custom events such as milestones, and can be assigned to colleagues [5]. Calendar integration syncs those dates to Google, Apple, and Outlook calendars [5]. With contract intake, site teams forward signed agreements to a unique email address [5]. Documents signed in the field still reach the central record. The pricing page shows what each plan includes.

Next step

Start with one active project, not the whole company. Gather its prime contract, every subcontract, and every signed change order. Record the fields above, and put each notice deadline on a calendar with real lead time. Name an owner for each contract. Then compare how your other projects handle the same fields.

For a single agreement, try the free construction contract reminder tool. It extracts milestone dates, retainage release conditions, and completion dates from an uploaded contract, then suggests reminder dates [6]. The construction contract calculator works out an end date and time remaining from a start date and duration [6]. Do you also manage buildings after handover? The guide on managing contracts for property management companies applies the same approach to a portfolio. When you are ready to track every project in one place, start a free trial and upload one project's contracts.
