Ian Robinson, BSc (Hons) LLB (Hons) MRICS ACIArb


Senior Partner

Ian is the Senior Partner at Tempus Delay Analysis LLP and leads a specialist team providing advice, support and expert analysis in relation to delay and disruption as it affects the construction and engineering industries both in the UK and internationally, and specialises in forensic investigation of construction and engineering delays.

Work has involved demonstrating the cause and extent of delay and disruption to construction and engineering projects including numerous different building types, bulk earthmoving and major road and bridge works, the construction of power stations (nuclear, coal, hydro and solar), oil platforms, pipelines and refineries, harbours and airports, military installations and process engineering facilities. Work has also involved advising developers, architects, engineers, contractors and subcontractors on delay/extension of time issues during the course of projects. Ian has extensive experience acting as expert witness and has given oral evidence in trials and arbitration hearings (both in the UK and internationally) on approximately 20 occasions over the past 25 years.

Ian is currently listed as a Global Elite Thought Leader by Who’s Who Legal, whose respondents described him as “very experienced, persuasive and calm under pressure” and “one of the best delay analysts around”.


Chris Dean, BSc (Hons)  ACIArb



Chris is a Partner at Tempus Delay Analysis LLP and was one of the key people to set the firm up in 2012, having already worked with Ian for several years previously. With over 15 years of experience in construction delay analysis on claims ranging in size from £1m residential refits to $300m power station disputes, Chris has a detailed knowledge of the techniques and skills required to undertake detailed forensic analysis. Having worked for both claimants and respondents in a variety of different construction disputes, Chris has extensive knowledge of the processes involved in the different dispute resolution methods including adjudication, arbitration and litigation.

Chris has produced delay and disruption claims to support contractor claims for extensions of time on large EPC projects, all of which have led to successful resolutions for the contractor. In support of these claims, Chris has acted on behalf of contractors in negotiation meetings, presentations and hearings to support the contractor’s position. This experience has given Chris a valuable insight into the challenges that contractors and employers face when delivering large EPC contracts.

Chris has carried out many different types of delay analysis including as-planned versus as-built and a number of large complex time-impact analyses, both supporting claims for extension of time and defending them. These have been supported by written reports capable of withstanding cross-examination.

In addition to forensic delay analysis, Chris is also familiar with the application of 4D planning which he has successfully used to illustrate critical delay. Chris co-presented the 2017 Practical Scheduling Delay Analysis course hosted by Asta PowerProject and has presented training courses on delay and disruption to clients in Spain.
