The Phasing Plan Had Nowhere to Put the Business

The construction sequence identified where departments would relocate. Nobody had confirmed whether those spaces could support the operation.

The contractor’s phasing plan showed how construction would move through the building and where departments would relocate as their spaces became construction zones.

The problem surfaced when the architect and department managers reviewed the proposed locations. Some were already occupied, others couldn’t accommodate the assigned functions, and several didn’t exist in the configuration shown.

The construction sequence depended on temporary space that nobody had confirmed was available or suitable. If that sequence became the basis for the project schedule and estimate, the owner could be making commitments around an untested assumption.

The Spaces Had to Work for the Business

The contractor understood when construction areas might become available. The architect and engineers needed to determine whether those areas could meet occupancy, accessibility, egress, ventilation, power, and other building requirements.

Department managers had to establish how their people would work. Some functions required privacy, others needed specific equipment or close coordination between employees, and customer-facing departments needed appropriate waiting and circulation areas.

There were also practical limitations to keeping the building occupied. Electrical work would affect active areas, construction noise would be difficult to contain, and access routes would change as work progressed.

As the team evaluated the proposed spaces, it became clear that the business could not operate within the original phasing plan.

Management continued exploring internal options before deciding that temporary trailer compounds elsewhere on the property were necessary.

Relocating the Business Became a Project of Its Own

The trailers introduced decisions that had not been considered in the original construction sequence.

Their fixed dimensions constrained furniture layouts and department arrangements. Some managers would lose private offices, departments would have to share space, and customer-facing functions still needed privacy and appropriate circulation.

Management had to determine which requirements were essential and where departments could adapt. Those decisions established the number and configuration of trailers needed.

The site presented another challenge.

With limited land and travel lanes, the trailers could not simply expand across the parking lot. Portions of the compound had to be stacked, introducing additional structural, accessibility, egress, and circulation requirements.

The compounds also needed power, internet, telephone, water, and sanitary service. Utility connections required coordination, approvals, and work through portions of the existing parking lot.

Meanwhile, the trailers displaced employee and customer parking, while contractors still needed room for deliveries, equipment, material storage, and exterior construction.

The temporary relocation now had its own design, infrastructure, permitting, cost, and schedule implications. Each of those requirements affected the construction project it was intended to support.

When Does a Proposed Sequence Become the Project Plan?

A contractor’s initial phasing sequence is a useful starting point. It identifies how construction might proceed and where temporary accommodations could be needed.

The risk arises when that preliminary sequence begins informing budgets, schedules, and leadership expectations before the operational assumptions have been tested.

In this case, reviewing the proposed spaces with the architect and department managers exposed the problem while the team was still developing the approach. Management evaluated the alternatives and ultimately determined that temporary trailer compounds were necessary.

That decision introduced substantial additional work, but it was based on understanding what the business required and what the building and site could accommodate.

Leadership Takeaway

Before approving an occupied construction phasing plan, ask your project manager to show where the affected departments have accepted their temporary accommodations and where the design team has confirmed those arrangements are feasible.

If those confirmations aren’t documented, the owner may be relying on an untested assumption that could materially change the project’s budget, schedule, and business operations.
