More than £5 million of additional value recovered across complex construction projects.

A developer instructed a contractor to value additional works using a Cost + Fee approach. Although the proposal appeared reasonable, it would have significantly reduced the contractor’s recovery. Roxburgh Murray reviewed the FIDIC contract and identified that the works should instead be valued using the agreed Schedule of Rates. We prepared and substantiated the valuation before negotiating directly with the developer.

A forestry subcontractor experienced prolonged disruption because other contractors repeatedly failed to provide access to the work areas. The Tier 1 contractor blamed the subcontractor’s resourcing and adverse weather. Roxburgh Murray challenged that position, identified multiple NEC Compensation Events, prepared fully substantiated quotations and supported the recovery with contemporaneous records over a six-month period.

The discovery of protected species restricted access, disrupted planned working sequences and reduced productivity. Roxburgh Murray demonstrated the wider effect on programme, methodology and project cost using detailed contractual analysis, programme evidence and robust supporting records. The Compensation Event was successfully agreed.

Late client design information pushed planned earthworks into the winter months, forcing the contractor to operate in significantly less favourable conditions. Roxburgh Murray demonstrated how the delay had changed the planned methodology, reduced productivity and increased construction costs. Detailed programme analysis, contractual assessment and cost substantiation secured acceptance of the contractor’s entitlement.

Late grid connection works caused significant delay, but the developer argued that the contractor had no entitlement to additional time or payment. Roxburgh Murray carried out a forensic review of the FIDIC Conditions of Contract and established that the delay was attributable to a Relevant Contractor engaged on the project. This changed the contractual position and secured both additional time and financial recovery.

Unforeseen physical conditions materially changed the planned construction works, creating substantial additional cost and programme pressure. Roxburgh Murray identified the contractor’s entitlement under the NEC Compensation Event provisions, prepared the required notices and valued the complete financial and programme impact. We then negotiated directly with the client to secure the contractor’s entitlement.

During excavation for a proposed substation, the contractor uncovered an unforeseen reinforced concrete basement. The discovery required a significant change to the planned construction methodology and created additional cost and programme impact. Roxburgh Murray prepared a fully substantiated NEC Compensation Event supported by site records, programme evidence and detailed cost information.
