What the Texas Cost Plus or Fixed Fee Construction Contract Is

The Texas Cost Plus or Fixed Fee Construction Contract is a written agreement between an owner and contractor that sets the contractor’s compensation either as actual allowable costs plus a fee (cost-plus) or as a predetermined lump sum (fixed fee). It defines scope, cost responsibility, change order handling, retainage, payment schedule, and completion milestones specific to construction projects performed in Texas.

Why this Contract Format Matters for Texas Projects

Selecting cost-plus versus fixed-fee affects risk allocation, incentives, and cash flow: cost-plus favors transparency and flexibility, while fixed-fee favors price certainty and tighter scope control.

Why this Contract Format Matters for Texas Projects

Typical Parties and Roles for This Contract

This contract is used by project owners, general contractors, and specialty contractors to establish payment terms and responsibilities before work begins.

  • Project Owner — defines scope, approves budgets, and issues payments according to the schedule.
  • General Contractor — manages construction, tracks costs, and submits invoices and change orders.
  • Subcontractor / Supplier — performs work under flow-down terms and provides lien waivers when paid.

Clear role definitions reduce disputes and facilitate lien management, payment bonding, and lien waiver workflows.

Core Elements to Include in a Professional Contract

A well-drafted Texas Cost Plus or Fixed Fee Construction Contract combines operational detail with payment mechanics so both parties know how scope, cost, and changes will be handled.

Scope of Work

Precise description of work, drawings, and attached exhibits to avoid ambiguity and scope creep.

Price Structure

Defines cost-plus formula or fixed fee, overhead allocation, labor rates, and allowable direct costs.

Change Orders

Procedure for approving, pricing, and documenting changes including time and cost adjustments.

Payment Terms

Progress payment schedule, retainage percentage, invoicing frequency, and required backup documentation.

Bonds and Insurance

Performance/payment bond requirements, insurance coverage limits, and certificate naming.

Dispute Resolution

Governing law, venue (typically Texas), lien rights, and arbitration or court procedures.

Step-by-Step: Completing the Contract

Follow this sequence to prepare, review, and execute a compliant Texas Cost Plus or Fixed Fee Construction Contract.

  • 01
    Gather Documents: Collect plans, specs, insurance certificates, bonds, and license numbers.
  • 02
    Choose Pricing Model: Decide cost-plus or fixed fee and fill the corresponding fee fields.
  • 03
    Define Payment Schedule: Set progress milestones, retainage, and invoice intervals.

How to Configure an Online Signing Workflow

Configure the e-sign workflow to match the contract’s approval order and required authentication.

Field Configuration
Signing Order Owner first | Contractor second
Authentication Email link or SMS code
Required Attachments Insurance | Bonds | Licenses
Retention Setting Automatic archive | PDF/A format

Where to Send and How the Document Moves

Typical routing: upload, assign roles, authenticate signers, capture signatures, and distribute executed copies to relevant parties.

  • Upload Document: Start with final contract PDF and attach exhibits.
  • Assign Signers: Map owner, contractor, and witnesses or notary roles.
  • Authenticate Signer: Use email link or stronger verification where required.
  • Deliver Executed Copies: Automatically send signed PDFs to all parties and retain audit trail.

Electronic Signing and Platform Considerations

Choose an e-signature platform that supports audit trails, export formats, and industry integrations required for construction workflows.

  • File Formats: PDF, DOCX, Excel supported
  • Integrations: Procore, NetSuite, Google Workspace
  • Authentication: SMS code, SSO, KBA options

Ensure the platform can store signed documents in tamper-evident formats, produce certificate-of-completion records, and integrate with your project management system.

Key Deadlines and Notice Periods to Track

Contracts create timing obligations for payments, notices, and lien-related actions that affect remedies and statutory rights.

Effective Date:

Date contract begins; triggers payment and warranty timelines.

Invoice Due Dates:

Specify net terms and progress payment intervals.

Change Order Notice:

State time window to submit price/time change requests.

Payment Dispute Notice:

Period to notify of withholding or claim.

Lien Filing Window:

Observe statutory notice and filing deadlines to preserve lien rights.

Project Milestones and Sequential Stages

Track these numbered stages from contract award through final closeout to manage payments and completion responsibilities.

01

Contract Award

Execute agreement and provide notice to begin mobilization.

02

Mobilization & Start

Contractor mobilizes personnel, obtains permits, and orders long-lead items.

03

Substantial Completion

Majority of work complete; triggers punch list and partial release of retainage.

04

Final Closeout

Complete punch list, final invoice, lien waivers, and warranty start.

Common Preparation Mistakes to Avoid

  • Vague scope language that leaves critical tasks undefined and triggers disputes over extra work and cost.
  • Failing to list allowable cost categories in cost-plus agreements, leading to audit disputes and withheld payments.
  • Missing signature authority documentation so an electronic signer lacks legal authority to bind a company.
  • Neglecting retainage and lien waiver sequencing; payments released without correct waivers create lien exposure.

Primary Risks and Legal Consequences

Mechanic’s Lien: Loss of lien rights if notices missed
Payment Withholding: Contractor risk if invoices noncompliant
Bond Forfeiture: Performance bond claimed for breaches
Delay Damages: Liquidated or actual damages exposure
Change Order Disputes: Unpriced changes lead to litigation
Tax Reporting: Incorrect payment reporting triggers penalties
