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.

• 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.
• Own the project budget, cost coding structure and monthly estimate at completion.
• Produce the monthly cost forecast with documented basis; no unsupported swings.
• Submit the monthly accrual to the client by the contractual deadline (typically two business days before month end).
• Prepare and submit progress billings; drive resolution of any invoice that ages past terms.
• Approve project timecards, vendor invoices, subcontractor pay applications and expense reports.
• Prep for and present to Area Manager each project for EOM updates

• Own the single schedule of record: baseline development, monthly updates, and all revisions.
• Integrate the Superintendent's three-week look-ahead into the schedule of record— they derive from it; they do not compete with it.
• Develop recovery plans jointly with the Superintendent when the project slips; own the client-facing schedule narrative.
• Own time-impact analysis and time-extension requests.

• Issue purchase orders and subcontracts within authority; route above-threshold commitments to the Sr. Project Manager.
• Own the procurement log and long-lead item tracking; elevate delivery risk before it becomes a schedule impact.
• Own subcontractor commercial relationships, scope definition, and pay application approval.

• Serve as the single point of client contact at the project level. Route client executive matters to the Key Account Manager and field coordination to the Superintendent.
• Chair the weekly project meeting; publish minutes with actions, owners and dates.
• Direct the Assistant Project Manager and Project Engineer; define the Assistant Project Manager's delegated scope in writing at kickoff and revise it when the scope changes.
• Support the Superintendent's field…
