What is a Change Order?

A change order is an official amendment to a construction contract that modifies the original scope of work, timeline, or contract price. Unlike simple invoice adjustments, change orders require formal documentation and approval from all project parties before payment can be made. These modifications happen frequently in construction projects as conditions change, unforeseen issues arise, or clients request additional work beyond the original contract specifications.

For subcontractors, proper change order management can make the difference between getting paid for extra work and eating the costs. The challenge goes beyond just documenting changes—it's staying on top of approvals, tracking work that's moving forward without final sign-off, and making sure everything gets billed correctly. Too often, change orders get lost in email chains, verbal requests never get formalized, or approved changes don't make it into the next billing cycle, leaving subcontractors stuck with unbillable work. (For a detailed breakdown of change order processes and best practices, check out our change order guide.)

Other construction terms

Pay-if-Paid Clause

What is a Pay-if-Paid Clause?

A Pay-if-Paid Clause is a contractual agreement prevalent in the construction industry. Generally, this clause can be found in subcontracts between the General Contractor(GC) and their subcontractors. According to the clause, the GC is not obliged to pay the subcontractors unless and until they themselves have received full payment from the project owner. Therefore, it effectively transfers the risk of the project owner's insolvency from the GC to their subcontractors. It serves as a protection for the GC against financial instability. This type of clause has its controversies, as some jurisdictions view it as unfair to subcontractors due to the assignment of financial risk.

Time-and-Material billing

What is Time-and-Material Billing?

Time-and-material billing is a method used in the construction industry where a client is charged based on the actual cost of labor and materials for a project, along with an added markup for the contractor's profit. This approach promotes transparency as customers directly pay for the time spent on the project and materials used. The advantage of this method is the flexibility it provides - if a project scope is unclear or likely to change, it can be more efficient than a fixed-price model. However, it also contains a risk for the client, with a chance that costs could increase if the construction takes longer or requires more resources than estimated. It requires meticulous tracking of working hours, materials, and equipment used. The client also needs to keep an eye on the project to avoid unnecessary costs.

Days Working Capital

What is Days Working Capital?

Days Working Capital (DWC) in the construction industry is a financial metric used to measure the effectiveness of a company's short term liquidity and operational efficiency. It's calculated by dividing working capital by daily operating expenses. The result represents the number of days a company can continue its operations with the current level of working capital. A lower DWC indicates a company is managing its cash flow efficiently, and a higher DWC may suggest a company is not using its short-term assets efficiently. The construction industry often has a high DWC because of the long project durations and upfront material and labor costs that are required before payment is received. In other words, they have money tied up in work-in-progress. So, for a construction company, it's crucial to manage DWC effectively to maintain a healthy cash flow and remain competitive.
