Most commercial construction and renovation work in Dallas-Fort Worth runs on a critical path method schedule, usually called a CPM schedule. The owner and the contractor look at the same file. They are not reading it for the same reasons, and the controls each side needs are different. Confusing the two is how a schedule that looks healthy on paper delivers a late turnover.
CPM in one minute
A CPM schedule breaks the work into activities, gives each a duration, and ties them together with logic: this cannot start until that finishes. The longest chain of dependent activities is the critical path, and it sets the finish date. Every other activity has float, the amount it can slip before it moves the finish. The approved version is the baseline. Each periodic update records actual progress and recalculates the dates, and short look-ahead schedules pull the next few weeks out for field coordination.
The value is not the chart. It is the logic. A schedule with sound logic tells you what a slip will cost before it happens. A schedule with dates typed in by hand only tells you what someone hoped.
What contractor-side controls track
On the contractor's side, the schedule is a commitment engine. The work is getting every party the job depends on to deliver on a date:
- Submittals and approvals. When each submittal goes out, when it is due back, and what is waiting on it.
- Procurement and lead times. Release dates, fabrication, and delivery for equipment and long-lead materials.
- Trade handoffs. Which trade must finish before the next can start, and whether the area is actually ready.
- Startup and testing. Manufacturer and integrator dates, prerequisites such as power and controls, and the people who must be on site together.
- Closeout and turnover. Punch, test records, operating and closeout documentation, and acceptance.
- Issues and decisions. What is blocking an activity, who owns it, and the date it needs an answer.
The output is a status report the project team can act on: what is complete, what is running, what comes next, and what needs a decision.
What owner-side controls track
On the owner's side, the schedule is an early-warning system. The questions are about exposure, not task management:
- Milestones that matter to the owner. Occupancy, turnover, and any date tied to a lease or an operation.
- Critical path movement. Whether the path changed between updates, and why.
- Float consumption. How much cushion the near-critical work has left, update over update.
- Change impacts. What each change order does to the dates, not only to the cost.
- Owner items on the path. Approvals, access, owner-furnished equipment, furniture, and technology. These are often the owner's own activities, and they are the easiest to miss.
Warning signs in a schedule update
- The finish date holds while activities keep slipping, which usually means float is being consumed quietly.
- Activities with no predecessor or no successor, so a slip cannot flow through the logic.
- Hard date constraints holding activities in place instead of logic.
- Actual dates recorded in the future, or progress reported on work that has not started its predecessors.
- Durations that shrink in every update without a reason.
None of these prove a problem on their own. Each one is a question worth asking before the next update, while there is still time to recover.
One side per project
Owner-side and contractor-side controls serve different loyalties. The contractor's project manager is accountable for delivering the commitments. The owner's representative is accountable for telling the owner when those commitments are at risk. One firm cannot do both on the same job without one of those duties giving way, so the role is chosen per project and stated in the proposal.
How Proportional FM handles it
Proportional FM works one side of a project, never both. For owners, that is owner-side project management: scope, milestones, change review, and verification against what was approved, with the contractor keeping means and methods. For mechanical contractors, it is contractor-side management of a defined assignment, such as vendor and equipment commitments from submittal return through startup, or closeout and turnover, reported in a Project Status Report. The scope, the responsibilities, and the reporting are defined in the proposal. For smaller jobs, see a lightweight PMP framework for small commercial projects, and for the distinction from a general contractor, is Proportional FM a general contractor?
