Job Summary:

Owns one project end to end: the contract, the money, the schedule of record, and the client project-level relationship. If the project makes or loses money, the Project Manager owns that outcome. The Project Manager is the only role that may authorize work outside the contracted scope, and the only role that commits the company to a client in writing at the project level.

Essential Job Responsibilities

Contract & Scope

▪              Own the contract: know what is in scope, what is excluded, what the notice requirements are, and what the deadlines for notice actually say.

▪              Conduct the scope handoff from estimating to the project team before mobilization; document assumptions, exclusions and allowances.

▪              Issue written notice of changed conditions within the contractual notice period — this is a Project Manager duty and cannot be delegated.

▪              Price, submit, negotiate and close change orders; maintain the change log with status and dollar exposure.

▪              Authorize extra work in writing. No other role may direct the company to perform work outside contracted scope.
