Biography

Mamas Stavrou is a managing director at Ankura, based in London. He is a chartered quantity surveyor with more than 25 years’ experience in the construction industry, now specialising in construction dispute resolution. He is a fellow of the Royal Institution of Chartered Surveyors, a fellow of the Chartered Institute of Arbitrators, and a Bond Solon-accredited expert witness.

Mamas is regularly appointed as expert witness on quantum and has testified in the Technology and Construction Court, in international arbitration, and in dispute board hearings. He is recognised as a leading expert in WWL: Construction.

Mamas’ professional experience includes expert reports and testimony on quantum in an ad hoc arbitration relating to a major waste water network and sewage treatment project in Oman. The amount in dispute was $90 million and concerned assessment of sums claimed in relation to alleged variations, delay, disruption, and loss of opportunity.

He also provided expert reports and testimony on quantum in a $50 million dispute in South African rules arbitration. The dispute involved assessment of the impact on equipment and labour from major scope changes and costs properly due to the claimant after termination of its contract for civil engineering and earth works on a mining project in Africa. The assessment predominantly entailed the analysis of equipment utilisation and the audit of equipment costs and third-party equipment supplier agreements.

Mamas provided expert reports and testimony on quantum in dispute concerning a 400MW combined cycle gas turbine power plant project in Latvia. The dispute concerned the assessment of costs arising from changes to equipment transportation requirements and restrictions from delays caused to the delivery of equipment and from delays caused to the commissioning process.

He also provided expert reports and testimony on quantum in the High Court in London (TCC) in Greenore Port Ltd v Technical & General Guarantee Company. The matter related to the assessment of costs properly due to the claimant in respect of the completion of port refurbishment and marine dredging works following replacement of the original contractor.

He was the lead assistant in the preparation of expert evidence on quantum in a $900 million dispute in ICC arbitration relating to the construction of a 540km LNG pipeline, receipt station, and associated mainline valves in eastern Australia. This involved examination and assessment of the impact on equipment and labour from delays, disruption and prolongation caused by variations to welding procedures and other major variations. The assessment entailed labour and equipment productivity analyses; audit of staff and labour costs and employment agreements; audit of equipment costs and equipment supply agreements; and audit of internal charging arrangements and accounting systems.

He was also the lead assistant in the preparation of expert evidence on quantum in a $100 million dispute in ICC arbitration relating to the construction of a nickel slurry pipeline project in Africa. This required assessment of the impact on labour and equipment arising from unforeseen ground conditions and late changes to cut and fill and reinstatement activities.

Mamas was the expert adviser undertaking peer review of the appointed quantum expert’s reports and analyses, and assisted the legal team, appointed on behalf of the lead joint venture partner, to assess the quantum for discrete aspects of the case. The claims related to delay, disruption and additional costs incurred as a consequence of termination, notably increased construction costs due to changed construction methodology arising from programme re-sequencing.
