David G. Waddle, FCIOB, FAPM, AMICE, MCIArb
Director, Delay and Construction Management Expert Witness

Background
David learned the construction process, including work study, construction planning, and project management, over 22 years working for Tier 1 national civil engineering, building, and management contractors as a senior planner, site agent, and project manager.
In 2000, David transitioned to consulting, where his reports have been presented in various tribunals, including the Technology and Construction Court (TCC) and Court of Session (Scotland), arbitration, and adjudication, and also instructed by the Dutch Court. Through cross‐examination, David has established himself as a delay expert with a successful track record, where disputes are regularly settled in favour of his client, often through a negotiated settlement. He is also an experienced project manager, with a strong focus on the restructuring of distressed projects.
In a civil engineering adjudication, his analysis demonstrated a 120‐week delay against an original 104‐week contract period. The adjudicator agreed entirely with David’s analysis and commented that David had “articulated his analysis clearly and comprehensively”.
In a building (JCT) adjudication, the adjudicator stated “…all of the relevant data including actual progress and its impact on the Completion Date must be considered. I prefer the approach adopted by Mr Waddle”. This resulted in the contractor being awarded a full Extension of Time.
David is a Chartered Fellow of the Chartered Institute of Building (CIOB). The CIOB states, “Gaining Fellowship status from the CIOB demonstrates a very high level of achievement: Fellows are among the most experienced and knowledgeable professionals in the industry”.
