Introduction

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.

Course Objectives

By the end of this training course, participants will be able to:

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

Target Audience

This training course is suitable for a wide range of professionals, including:

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

Training Methodology

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.

Target Competencies

Heads of claim analysis
Variation valuation
Prolongation cost calculation
Disruption quantification
Cost record substantiation
Quantum assessment
