Contractor Contract Essentials

Defective contractor contracts are the single largest source of payment disputes, scope creep, and project shutdowns on Guam job sites. A contract missing a defined change-order process or a clear termination clause can stall a $2 million project for months — and that figure doesn't account for liquidated damages, subcontractor claims, or surety involvement. Every licensed contractor operating in Guam's construction market needs a contract structure that holds up against federal procurement rules, territorial requirements, and the specific conditions of island logistics.


What a Contractor Contract Must Include

Parties and License Information

The contract must identify all parties by legal entity name, not trade name. Include the contractor's Guam Contractor's License number, the license classification (e.g., General Building — B, or the applicable specialty trade category), and the client's legal name and address. A contract signed under an unlicensed or expired classification is unenforceable under Guam Public Law and exposes the contractor to administrative penalties.

Scope of Work

Scope of work language is where disputes begin. The scope section must specify the exact work being performed — referenced drawings, specification sections, applicable codes (IBC 2018 as locally adopted, NEC 2020, or applicable plumbing code), and explicit exclusions. "Demolition and replacement of roofing membrane per Section 07500 of project specifications" is enforceable. "Roofing work as discussed" is not.

Per the Federal Acquisition Regulation (FAR), scope definitions in government-facing contracts must be precise enough to allow competitive bidding on identical terms — a standard that applies as best practice on all commercial contracts as well.

Compensation, Payment Schedule, and Retainage

The compensation section must state the total contract value, the payment milestone schedule, and the retainage percentage. Guam construction contracts commonly carry 10% retainage on progress payments, released upon substantial completion and punch-list sign-off. Payment trigger events — tied to specific inspections, delivery confirmations, or percent completion — must be defined in writing. Vague "payment upon progress" language creates leverage disputes.

Federal prevailing wage requirements under the U.S. Department of Labor Wage and Hour Division apply on federally funded Guam projects. Davis-Bacon Act wage determinations must be incorporated by reference into the contract and posted at the job site.

Change Orders

No change order provision is a contract defect. The section must require all scope or cost changes in writing, signed by both parties before work begins, with a defined timeline for response (typically 10 calendar days). Oral change-order authorizations are unenforceable in most construction disputes. The change-order log becomes part of the contract record.

Schedule and Substantial Completion Date

Define the commencement date, the substantial completion date, and the final completion date as separate milestones. Attach a baseline schedule — a Gantt chart or CPM schedule is acceptable — as a contract exhibit. Liquidated damages provisions, if applicable, must state a specific dollar amount per calendar day of delay, not a formula that references unspecified costs.


Bonding, Insurance, and Compliance Requirements

Performance and Payment Bonds

On federally funded Guam projects over $150,000, the Miller Act (40 U.S.C. §§ 3131–3134) requires both a performance bond and a payment bond at 100% of the contract value. The SBA Contracting Guide addresses surety bond requirements for small business contractors pursuing federal work, including SBA's Surety Bond Guarantee Program for contractors who cannot obtain bonds through commercial markets.

Insurance Minimums

At minimum, the contract must require: - Commercial General Liability: $1,000,000 per occurrence / $2,000,000 aggregate - Workers' Compensation: statutory limits under Guam law - Automobile Liability: $1,000,000 combined single limit - Builder's Risk: project value, named perils or all-risk

Name the project owner as an additional insured on the CGL and Builder's Risk policies. Require certificates of insurance before mobilization.

OSHA Compliance Language

The contract must include a provision requiring compliance with all applicable OSHA Construction Standards under 29 CFR Part 1926. Subcontractors must be contractually bound to the same OSHA compliance terms. On multi-employer job sites, the general contractor carries responsibility for OSHA compliance as the controlling employer — a failure mode that results in citations even when subcontractors cause the violation.


Multiyear and Federal Contracts

For contractors pursuing ongoing federal facility work on Guam — NAVFAC Pacific projects, federal building maintenance, or GSA-managed properties — multiyear contract structures are governed by 10 CFR § 436.34, which establishes the authorized terms and conditions for multiyear agreements. Contractor selection procedures under these programs follow 10 CFR § 436.33, and qualified contractor lists are maintained per 10 CFR § 436.32. Contractors not appearing on an applicable qualified list cannot be awarded work under those vehicles regardless of bid price.


Termination Provisions

A contract without a termination clause leaves both parties without a structured exit path. The termination section must distinguish between termination for cause and termination for convenience. 10 CFR § 436.38 establishes the federal framework for contract termination procedures, including notice requirements, dispute resolution steps, and settlement of work-in-place costs. Even on private Guam projects, this structure — written notice, cure period, documented accounting of completed work — reduces exposure on both sides.


Construction Manager Roles and Contract Responsibility

According to BLS Occupational Outlook data for Construction Managers, construction managers carry contractual responsibility for safety, scheduling, cost control, and coordination across trades. On Guam projects where a general contractor acts as construction manager, the prime contract must specify whether the CM role is agency-based or at-risk, because the liability structure differs substantially between the two delivery methods.
