Mr David Byrne

Mr David Byrne

Group Bid Director

David’s time with Mercury essentially began at a grassroots level as he started off as an electrical apprentice in July of 1996. During this time David worked mainly in commercial, process and pharmaceutical projects throughout the country. David’s first progression was to Junior Estimator/QS in March 2000 where David was relocated to our Head office on a full time capacity.

Towards the end of his apprenticeship David started to look after the finance on some smaller projects and this caught the attention of his peers as they felt he had the potential to work in a further role.

As a Junior Estimator David would work on projects ranging in value from €100k to €5m, these were generally Commercial, Pharmaceutical, Data Centre developments. David would have gathered vast amounts of experience as he was involved in tendering for some of the biggest projects in the country at the time. Examples such as the 3 Arena, Shell Corrib Pipeline, and Enniskillen Hospital are just a few names on a very impressive resume. David would quickly progress through the ranks as he was made senior estimator in 2007. In 2009 David became responsible for the estimation of our projects in the UK and was based full time in our London office during 2010 & 2011.Following on from the position in London he returned to Ireland and found himself responsible for all of the estimating and commercial management on projects on the Wafer Fabrication Facility –Kildare. Dave represented a team of Estimators & QS’s which would vary in number and project value between €1million up to €70million.

In his current role as Bid Director he is responsible for all projects from pre-qualification through estimating to contract award. He leads varying teams compiled of both estimation and a pre-construction team which when combined feed into the overall Bid management process which he developed within the business. Within his role he reports directly to the Executive Management team who feel that the development of the Bid Management process within the group as assisted the business greatly in identifying both risk and opportunities on projects during tender periods.

He has completed varying courses in further education from Diplomas in both Legal Studies and Project Management, a Post Graduate Diploma in Construction and Contract Law from Trinity College and currently in the final stages of a Masters in Quantity Surveying.

The above professional qualifications along with the varying experience gained have led David to be seen as a senior professional of industry which led to his position as a member of the PT&C committee in the CIF and recently appointed Chairman of the Contracts Committee in the CIF.
