3 metrics every property investor should track during a build

Most property investors spend significant time analysing a deal before committing: location, yield, comparable sales, financing costs. The financial discipline applied to the acquisition decision is, in most cases, entirely absent once construction begins.

Once the contractor is appointed and work starts, the typical investor position is passive. Progress updates are vague. Site visits are infrequent. The assumption is that the contractor will flag anything important. That assumption is where money gets lost.

Construction has measurable variables at every stage. Tracking the right ones does not require technical expertise. It requires knowing which questions to ask and insisting on documented answers.

Metric 1: Budget consumption versus physical progress

The most basic financial control in construction is the relationship between how much has been spent and how much has actually been built. These two numbers should move together. When they do not, there is a problem.

If 60% of the budget has been invoiced but only 40% of the physical work is complete, the project is running over budget relative to its stage. The gap will not close by itself. It will widen, because the remaining work still needs to be executed with a reduced budget.

Investors should require a monthly breakdown that shows budget consumed by category against the corresponding physical completion percentage for that category. Any deviation above 10% in either direction warrants a formal explanation from the contractor.

Metric 2: Schedule variance by phase

A construction programme is not a single end date. It is a sequence of phases, each with its own start and finish, each dependent on the previous one being completed correctly before it can begin.

Tracking schedule at the phase level matters because delays compound. A two-week slip in the structural phase does not simply push the finish date by two weeks. It delays the start of mechanical and electrical works, which delays finishes, which delays inspections, which delays occupation or sale. A two-week structural delay can easily become a six-week overall delay by handover.

Investors should ask for a live programme updated at least monthly, showing planned versus actual completion for each phase. A contractor who cannot produce this document does not have the project under control.

Metric 3: Variation orders issued

A variation order is a formal change to the agreed scope of work. Every variation order has a cost implication, and most of them are avoidable with adequate upfront planning.

Tracking the number and cumulative value of variation orders issued during a project is one of the clearest indicators of how well the project was planned before execution began. A project with zero or near-zero variation orders was well specified. A project generating variation orders regularly was not.

Investors should require that every variation order be documented in writing before the corresponding work is executed, with a clear description of what changed, why it changed, and what it costs. Verbal agreements on variations are how budgets disappear without trace.

Why these three metrics matter together

Budget consumption, schedule variance and variation orders are not independent signals. They interact. A project running over budget is often also running behind schedule, and both problems frequently trace back to a high volume of variation orders driven by inadequate initial scope definition.

When all three are tracked together, an investor can identify early whether a project is under control or not, while there is still time and budget to intervene. Waiting for the contractor to raise the alarm is not a strategy. By the time a contractor raises the alarm, the options available to the investor have already narrowed considerably.
