Burghfield Common Residential Development

Challenge
A major residential development where imported fill requirements, infrastructure costs and abnormal works created significant uncertainty during the land acquisition process.
Approach
Undertook a detailed review of the proposed development, including earthworks, plotworks and infrastructure requirements, applying specialist groundworks engineering knowledge to establish realistic quantities where information was incomplete and validate likely costs using current market pricing.
Outcome
Improved visibility of likely development costs and associated commercial risk, supporting informed land acquisition decision-making before commitment.
Hertfordshire residential development
800 units • Development appraisal review

Hertfordshire Residential Development

Challenge
A large residential development where incomplete information and significant level variation created uncertainty within the original development appraisal.
Approach
Undertook a detailed review of earthworks, retaining structures, attenuation features and infrastructure requirements, applying engineering judgement and practical construction knowledge to establish realistic quantities and assess likely development costs.
Outcome
Identified materially higher earthworks requirements than originally allowed within the appraisal, improving visibility of potential development costs and associated commercial risk.
Lyme Regis Phase 2 residential development
159 units • Complex Levels & Groundworks Review

Lyme Regis Phase 2

Challenge
Stepped foundations, varying plot designs and significant level changes created complex earthworks and groundworks exposure.
Approach
Produced an independent measured review including cut and fill calculations, foundation allowances and groundworks quantities across the development to establish realistic construction requirements.
Outcome
Improved visibility of likely construction costs and enabled the client to challenge tender quantities before commitment.
Modbury replan review
Replan measure • Drawing revision review

Modbury Replan Review

Challenge
Additional plots, revised house types and changes to the development layout created uncertainty around the true commercial impact of the replan and the contractor's associated claim.
Approach
Completed an independent review of the revised development information, including additional plots, revised house types and layout changes, to assess the resulting impact on quantities, groundworks requirements and associated costs.
Outcome
Provided the cost impact of the replan and supported agreement of a reduction against the contractor's claim.
