Interface failures between trades on live construction sites are one of the most common causes of programme drift and cost overrun. A scaffold contractor believes their handover is complete; the roofers arrive to find boards moved. A groundworks package appears to be finished; the external works crew discovers formation levels are wrong. Each is a small friction that costs days. Cumulatively they cost weeks.
The mechanism that prevents interface failures
The mechanism that prevents most of these failures is not complicated. It is a weekly coordination meeting where the trades due to interface with each other in the coming week talk about what is being handed over, in what state, and what the receiving trade needs it in. Done properly, the meeting takes thirty minutes. It saves days across the following week.
Where the trades on a scheme are procured from separate contractors, the coordination meeting is difficult to make happen consistently. Each contractor’s supervisor is focused on their own work. Attending a coordination meeting that discusses other contractors’ handover status feels tangential to the immediate priority. Even when the principal contractor convenes the meeting, attendance and engagement can be uneven.
Where multiple trades are delivered by a single specialist group, the coordination meeting is internal rather than convened. It happens as a matter of the group’s normal operational cadence. Attendance is guaranteed. Engagement is high because everyone in the room has the same set of overall performance metrics from the group’s leadership.
How the Globe Group runs its weekly coordination
The Globe Group’s weekly site coordination meeting on schemes where multiple group trades are delivering is a standing item run by the account director for the scheme. Every trade active on the site during the following week is represented. Every interface between trades is discussed. Handover states are agreed. Adjustments to sequencing are made. Actions are minuted with names and dates.
The outputs of the meeting flow into the site diary and into the trades’ daily briefings for the following week. Operatives arrive at handovers expecting them in the condition that was agreed on Friday. Where the actual condition differs, the deviation is identified quickly and resolved rather than allowed to become a defect that emerges later.
There is a specific benefit around programme adjustment worth mentioning. When a trade is running ahead or behind schedule, the coordination meeting is where that information gets shared with the trades affected. Adjustments to subsequent handovers can be made proactively rather than reactively. The programme absorbs the variance with minimal disruption.
How this complements the principal contractor’s own programme reviews
For principal contractors, the group’s internal coordination meeting is complementary to their own weekly programme reviews rather than a substitute. The principal contractor still convenes their own review of all contractors on site. But the group’s internal meeting means the group’s trades arrive at the principal contractor’s meeting with their interfaces already coordinated, so the principal contractor’s meeting can focus on the harder cross-group coordination questions.
For developers, the effect is a scheme that runs at the pace the programme assumed rather than at the slower pace that interface friction typically produces. The weekly coordination discipline is one of the operational reasons that group-delivered schemes tend to hold their dates more reliably than mixed-contractor schemes.
The cost of the meeting is negligible. The cost of not having it is real. The habit either exists in the group’s operating rhythm or it does not, and the difference shows up across every scheme the group delivers.
