Rebuilding the evidence behind modular construction claims

We supported a modular-building specialist reviewing disputed compensation events on a major rail development. The issues ranged from design change and deferred access to restrictions affecting the installation and storage of completed modules. We examined entitlement and valuation separately, rebuilding event-specific records so that the client could understand the basis, supporting evidence and commercial significance of each claim.

Background

The account contained a substantial history of quotations, assessments and implemented compensation events. Some matters had been accepted in principle but remained disputed in value; others had been rejected and needed a more precise explanation of the contractual event.

The client required a reliable view of that position before deciding how to pursue the differences. Repeating the original claims would not resolve questions about overlapping costs, the basis of valuation or the evidence needed to support a particular installation constraint.

Our approach

We brought the events into an overall schedule covering five workstreams. It retained the notification, contractual status, quoted and assessed amounts, implementation position and our valuation. This distinguished an accepted event from agreement with the client’s price and kept existing assessments separate from sums that remained under review.

For the valuation work, we compared the original quotation and contractor assessment line by line. The schedules identified the quantities, periods, allocations and rates behind staff, storage, transport and other costs, with separate comments explaining the basis we considered supportable and the information still required.

Deferred access required close attention to the subcontract’s pricing mechanism. We examined the specified premobilisation allowance before considering additional staff costs, so that the assessment addressed potential overlap rather than simply adding every recorded cost to the claim.

Module storage was assessed against the manufacturing and installation sequence and the contract’s free-storage period. The calculations identified the relevant dates for individual modules. Where the available completion records did not support a date consistently, we recorded the evidence needed to test the calculation rather than treating the schedule as conclusive.

The installation-access work required a different form of substantiation. We reviewed the original notifications and rejection reasons, then examined the subcontract information, lifting plans, drawings and site records to explain the particular constraint and the alternative contractual basis being advanced.

One example concerned the effect of ground-bearing and access restrictions on the planned lifting arrangement. The narrative connected the specified working area with the larger equipment and revised installation method being put forward. Another examined why an alternative storage area was not operationally equivalent to space within the planned lifting zone, including the additional trailer and handling requirements.

We separated those events from a broad allegation of disrupted installation. Issued entitlement documents described the relevant obligation, the evidence of the changed condition and its practical effect. Valuation and remaining information requirements could then be considered against that defined event.

The review also distinguished an assessment grounded in the contractual record from alternative positions being developed for the client’s consideration. This allowed the commercial discussion to address both the potential value and the evidential foundation of the next step.

Outcome

The client received detailed valuation schedules, an overall event record and issued entitlement narratives for selected disputed access matters. The work gave it a clearer basis for further discussions and for deciding which issues warranted additional evidence or escalation.

Our contribution was to connect the contract, the physical constraints and the cost calculation at event level, replacing a fragmented claims history with a position that could be examined and explained.
