Executive summary
The procurement mistakes that delay apartment projects are remarkably consistent — rarely dramatic, rarely the fault of one party, and almost always avoidable. The five below are procurement-structure problems, best addressed before the first package is awarded.
The procurement mistakes that delay multi-residential projects are remarkably consistent. They are rarely dramatic, rarely the fault of a single party, and almost always avoidable. Drawn from recurring patterns across apartment delivery, the five below share one trait: each is inexpensive to prevent during design and costly to correct once construction is underway.
1. Engaging suppliers too late
The most common and most expensive mistake is bringing key system suppliers in after the design is fixed and the programme is set. By then, buildability input arrives as a variation rather than a design improvement, and lead times that could have been planned around become constraints. Early engagement converts supplier knowledge into programme certainty; late engagement converts it into rework.
2. Incomplete or inconsistent documentation
Packages tendered on incomplete documentation are priced on assumptions, and assumptions become variations. Where structural, façade and window information is inconsistent between disciplines, each supplier prices its own interpretation — and the gaps are reconciled on site at the head contractor's cost. Complete, coordinated documentation is the cheapest risk reduction available on any project.
3. Fragmenting interdependent packages
Splitting structurally and dimensionally dependent systems across many separate suppliers multiplies interfaces and the coordination required to manage them. Each additional package is another lead time, another set of shop drawings and another boundary where responsibility can be disputed. Fragmentation is sometimes unavoidable, but it is frequently a default rather than a decision.
4. Leaving coordination to the site
When interface coordination is deferred to construction, it competes with every other site priority and is resolved under time pressure. Clashes between frame, façade and glazing that would take an hour to resolve in a model take days to resolve in place. Coordination is a design-stage activity; treating it as a site activity guarantees it will be done at the worst possible time.
5. Sequencing procurement by the tender calendar
Awarding packages in the order they happen to be ready, rather than in the order the project depends on them, locks downstream trades into upstream assumptions. Setting-out and long-lead systems should be procured first, so following packages design to confirmed information. The dependency between framing, façade and glazing is explored further in coordinating structural framing, façades and windows.
Lessons and best practice
None of these mistakes is the result of poor trades or poor products. They are procurement-structure problems, best addressed before the first package is awarded. Experienced developers increasingly engage key suppliers during design, insist on coordinated documentation, and consolidate interdependent systems to reduce the number of interfaces they manage. The pattern across successful apartment projects is consistent: the programme is protected in the procurement strategy, not recovered on site.
The same principles underpin the wider move toward integrated building systems.
