Contractor documentation and due diligence

Surprisingly, many losses, liabilities, and subsequent insurance claims do not result from a contractor’s negligence on a project, but rather from the contractor’s inability to provide the required details of work performed. This includes the materials purchased, the suppliers hired, as well as the documentation to verify work performed by sub-contractors.

As a contractor, it’s your responsibility to have the documentation and do your due diligence for all contracting services. There are various categories of documentation that contractors need to obtain, maintain, and keep readily accessible for review or audit upon request.

Documentation and procedures

Work is performed by several types of contractors in all sectors of the economy. In this world of due diligence, it’s the responsibility of the contractor to obtain documentation on work performed and materials used to complete a project. Since actions against a contractor can occur many years after project completion, efforts should be made to retain these documents indefinitely. When a system is implemented at the onset of each project, maintaining proper documentation is not as complex or cumbersome as it may seem.

There are many types of documents to obtain and maintain if your work is called into question, such as:

  • Contracts and construction schedules
    • Contracts and contract drawings including indexes, revisions, and as-built drawings
    • Technical specifications, revisions, and addenda
    • Shop drawings, records, and daily logs
  • Tenders, material invoices, purchases, and payments
  • Progress reports, daily logs, inspection reports, and testing reports
    • Progress schedules and reports
    • Inspection reports and procedures
    • Survey and audit reports
    • Validation reports
    • Equipment service and maintenance records
  • Meeting notes (management and labourers) and project changes
  • All correspondence between the contractor, owner, architects, engineers, and sub-trades
  • Certificates of Insurance from sub-contractors, consulting engineers, etc.

Develop document procedures that are appropriate and specific to your contracting operations or services. Once procedures are in place, it is equally important to ensure that all managers, supervisors, construction forepersons and workers understand and abide by the procedures. A good company practice is to host a workshop on documentation retention procedures with your employees.

You can ask them to sign a document confirming they understand the topic and have received a copy of the procedures.

Understand your role

To determine the types of contracts and documentation to produce, fill out, track, and maintain for yourself and your project contributors, you should be knowledgeable about each role involved. When working in coordination with different parties, it is crucial to understand your role in a project and the responsibilities that fall within it. Stay aware of every aspect of a project that you may be held accountable for and complete them accordingly. Below is a list of different project contributors that may describe your role, or that of your collaborators, as well as the responsibilities that are typically assigned to them in a project.

This file would contain inspection reports and checklists which list all your duties outlined in the contract, as well as some additional best practices.
