Directive vs RCO in construction

Construction teams use directives and RCOs together constantly, but they serve different purposes. Knowing the difference — and keeping them linked — is what separates a clean change order log from a billing dispute six months later.

The directive: proceed now, price it later

A directive is the owner's or engineer's instruction to start work immediately — before the cost, schedule impact, or full scope has been agreed on. Field conditions don't wait for paperwork. The directive acknowledges that and authorizes the contractor to move forward on trust that the cost will be worked out.

The risk for contractors: if the directive isn't in writing, it can be very hard to collect later. Get it in writing, log it with a date and location, and attach any supporting field photos.

The RCO: your formal cost and scope response

After work is directed, the contractor prepares and submits an RCO — a formal document that prices the change, describes the scope, and identifies any schedule impact. This is what eventually becomes the signed change order, or the subject of a dispute if the owner doesn't agree with the pricing.

Tracking both on the same map pin

In HeavyCivilHelper, you log the directive immediately as a pin at the location of the changed work — date, description, who issued it, photos. The linked RCO is attached to the same pin as it moves through pricing and approval. Both sides of the change event stay together and tied to the place on the project where they happened.

Frequently asked questions

What is a construction directive?

A directive is an instruction — usually from the owner or engineer — to proceed with work immediately, before full pricing or formal approval. It authorizes the contractor to start work on a change while the cost and scope details are still being worked out.

What is an RCO in construction?

RCO stands for Requested Change Order (sometimes called Request for Change Order). It's the contractor's formal pricing and scope document submitted to the owner for review and approval after work has been directed or a change has been identified.

Which comes first — the directive or the RCO?

Usually the directive comes first. The owner needs the work done immediately, so they issue a directive to proceed. The contractor then submits an RCO documenting the cost and impact. On some jobs these happen in the opposite order, but urgent field conditions almost always lead with the directive.

What happens if you proceed without a directive in writing?

You risk losing your claim to additional compensation. Most contracts require written authorization before performing extra work. A verbal instruction from a field inspector or project manager — even if entirely legitimate — can be difficult to enforce without written backup.

Can one change generate multiple RCOs?

Yes. A single directive might generate separate RCOs from the GC, the concrete sub, the electrical sub, and the testing lab. Each party prices their own scope and submits separately. Tracking which RCOs tie to which directive is part of the project management challenge.
