Construction Contracts and Contract Documents: A Comprehensive Guide


Introduction to Construction Contracts

A construction contract is the cornerstone of any project and the only binding legal document between the parties. This detailed contract specifies not only the parameters of the project and the terms under which it will be completed but also the procedures to be followed in the event of any unforeseen complications. The contract acts as a shield, objectively recording the mutual understanding between the contractor and the client. The contract plays a crucial role since disagreements frequently arise when one party insists on more labor without offering to pay for it.

Types of Construction Contracts

There are several types of construction contracts, each suited for different project scenarios. Let’s take a closer look at some of the most common types:

  1. Fixed Price Contracts: Also known as lump-sum contracts, these agreements establish a fixed price for the entire project. The contractor agrees to complete the work for a set amount, regardless of any cost fluctuations or unforeseen circumstances.
  2. Cost Plus Contracts: In this type of contract, the owner agrees to reimburse the contractor for the actual costs incurred during the project, along with an additional fee or percentage of profit.
  3. Time and Material Contracts: These contracts are commonly used when the scope of work is uncertain or subject to change. The contractor charges for the time spent on the project and the materials used, plus an agreed-upon markup.
  4. Unit Price Contracts: Unit price contracts involve pricing the project based on specific quantities or units of work. The contractor provides a price per unit, and the total cost is calculated based on the actual quantity of work completed.

The Virtues of a Construction Contract

This legal instrument boasts two commendable virtues:

  1. Harmony at the Project Onset: By aligning the client and contractor on a shared understanding, the contract facilitates a seamless project initiation.
  2. Legal Recourse Definition: In case of disagreements during the project, the contract outlines the legal recourse available to each party, ensuring resolution pathways are clear.

Empowering Civil Engineers

Civil engineers rely heavily on construction contracts to ensure the safety of their projects and safeguard their financial investments. Quick resolution of disputes requires an understanding of the relative relevance of the various contract documents. This article explains why civil engineers need to know the preferred arrangement of papers in building contracts in order to conduct their jobs successfully.


The needed Documents

In the event of a disagreement, the precedence of papers plays a key role. The following is the usual pecking order, as stated in the contract itself:

  1. The contract
  2. The drawings
  3. The specifications
  4. The conditions of contract
  5. The tender documents

Diverse Forms of Construction Contracts

Construction projects come in all shapes and sizes, and so do the contracts governing them. The type of contract is frequently determined by the compensation scheme. The four most frequent are as follows:

  1. Lump Sum/Fixed Price: Providing a single number for the entire project, this contract form ensures the client of a predefined expenditure and incentivizes the contractor to complete the job efficiently. All potential outcomes, target dates, and accompanying bonuses or fines must be spelled out.
  2. Cost Plus: The client pays for everything, plus a predetermined amount (or percentage) to cover the contractor’s profit. While this does safeguard the contractor, it may increase the overall project price if the contractor’s safety net is not included.
  3. Time and Materials: Tied to hourly or daily rates for labour and actual material costs, this contract necessitates clients to cover unexpected project costs. This may include the contractor’s overhead or markup on materials acquired.
  4. Unit Pricing: This agreement takes a metric-based approach to the project’s tasks, scope, and materials.

Tailoring the Contract to Your Needs

Selecting the most suitable construction contract depends on project type, client expectations, and payment structuring preferences between the contractor and the client. Understanding these dynamics ensures a harmonious and mutually beneficial contractual relationship.

Constructing Your Contract: A Comprehensive Guide


Identifying/Contact Information

Essential elements in drafting a construction contract for your project are the names and contact information of all parties involved.

Personal Data of Customers:

  • Title (or company moniker)
  • Contact info (including phone and email) and precise property details

Contractor Details:

  • Name, Company Name, Contact Number, Email Address, Physical Location, and Insurance and Permit Details

Title and Description of the Project

Your contract not only names the project but also explores its details.


  • Project title (e.g., “Two-Car Garage with Second Story Studio”)
  • Project description, potentially with dimensions and specifications
  • Attachment of blueprints or plans, duly signed by both parties
  • Licenses, Permits, and Project Details

Ensure that your construction contract outlines all necessary licenses, permits, and essential project details.

Include Project scope, components, and materials, perhaps with blueprints and attachments. Consequences for failing to meet the deadline.


Cost Estimate and Payment Schedule

A construction contract is incomplete without specifying the cost estimate and payment schedule.


  • Non-refundable deposit before project commencement
  • Additional payments tied to project completion milestones
  • Inclusion of late fees, protecting the contractor in case of delayed payments

Stop Work and Stop Payment Clauses

Given the contractual obligations, clauses must address the right to stop work due to non-payment or project delays.


  • Legal rights for the contractor to stop work if the client fails to pay
  • Client’s right to withhold payment if project milestones are not reached on schedule

Act of God Clause

Standard language in your contract templates should protect against unforeseen circumstances.


  • Clause outlining how work will proceed in events like hurricanes, earthquakes, or material shortages
  • Depending on location and potential risks, ensure boilerplate language covers unexpected scenarios

Change Order Agreement

Projects evolve, and your contract must adapt to changes in scope or additions.


  • Specification of how changes will be handled
  • “Change order” agreement to facilitate adjustments in scope and payment


Address client concerns by standing behind the quality of your work.


  • Warranty clause guaranteeing correction of problems for a specified period (typically one year)
  • Establish trust by showcasing your commitment to quality workmanship

Dated Signature from Both Parties

Solidify the legality of your contract with dated signatures from both parties.


  • The contract is officially binding upon mutual agreement
  • A clear understanding of responsibilities and commitments by both parties
