Introduction

Course overview

Establishing entitlement to additional time or money is only half of a successful construction claim. The other half is quantum: proving, with reliable records and sound methods, exactly how much the claimant is owed. Many claims fail or are heavily reduced not because entitlement is weak but because costs are poorly substantiated, double counted or calculated using inappropriate methods.

This Construction Claims Quantum and Cost Substantiation training course provides a detailed, practical understanding of how to prepare, present and evaluate the financial value of construction claims. Participants learn about heads of claim, the valuation of variations, prolongation and disruption costs, head office overheads, loss of productivity, finance charges and the records needed to support each element.

The course is relevant to both contractors preparing claims and employers, consultants and assessors who need to evaluate them objectively.

What you will achieve

Learning objectives

  • Explain the relationship between entitlement, causation and quantum
  • Identify the main heads of claim in construction disputes
  • Value variations using contract rates, fair rates and actual cost
  • Calculate time-related prolongation costs accurately
  • Apply recognised methods to quantify disruption and lost productivity
  • Evaluate head office overhead and profit claims
  • Assemble records and evidence that substantiate costs
  • Assess and respond to quantum submissions objectively

Who should attend

Target audience

  • Quantity surveyors and cost managers
  • Commercial and contracts managers
  • Claims consultants and analysts
  • Project managers and project directors
  • Employer representatives and engineers
  • Legal advisers working on construction disputes

Methodology

Learning approach

  • The course uses worked examples, sample claim documents and case studies based on realistic projects. Participants value variations, calculate prolongation and disruption costs, test overhead formulae and review a quantum submission to identify weaknesses. Group discussion compares contractor and employer perspectives.
