Carl Vink Managing Director

A car enthusiast, Carl was delighted to start his career at the Rover car plant in Oxford. The first of a new breed of combined mechanical and electrical engineers, he  successfully completed a 4 year apprenticeship and began working for BMW as part of the team overseeing the electrical infrastructure for the new Mini in Oxford. From an early age Carl was interested in fitness and weight training, progressing to bodybuilding in 1997 and becoming a British Champion in 2001.

Having a natural flair for project management and looking for a change in industry, contracting seemed the logical step and so in 2000 Carl joined GA Electrical, then a small family run business. Starting as a project manager he helped grow the business, becoming a director in 2003. From 2004 his main aim was to expand the business by offering clients a level of service and professionalism unheard of from an electrical contractor. This paid dividends
as by late 2009 the turnover had tripled. In 2010 Carl became Managing Director of GA and remains an integral part of the team, heavily involved in business development and ensuring GA Electrical and Mechanical continues to deliver the service its customers they deserve and expect.

Successfully completing a wide range of commercial contracts for 5 years, in 2010 he completed his HNC in Contract Management and then, having a natural flair for detail and great success negotiating projects it was a natural progression to become GA Electrical’s Estimating Manager in 2010, before being made a Company Director in 2011. Adam’s role is key to business growth and he has ultimate responsibility for all quotations and budgets for a wide variety of projects, ranging from fully specified to complete design and build projects. To ensure a smooth transition from tender to project build, Adam stays close to the majority of projects alongside the contracts team, assisting in the contract design, procurement and quantity surveying. With Adam’s extensive experience in electrical system installation and contracts management, he has a full understanding of the complete process, from project tender to project completion, ensuring that our tenders are accurate and all-encompassing.

Paul Clarke Director of Works Department

Paul started his career as an electrical engineer within the automotive industry completing a 4 year apprenticeship with the Rover Group in Oxford, eventually working and training in Regensburg, Germany and Longbridge, UK to oversee the transfer of companies from Rover to the BMW Group.

Paul progressed from BMW to an electrical engineering and project management role within different sectors including the food industry, working with companies such as Witwood Foods/Newley Weds and Lantmannen/Unibake. During his time here Paul managed both large scale projects critical to business growth and also ran successful maintenance teams.

Paul first joined GA Electrical in 2010 as an estimating manager before working more recently as a quantity surveyor/project manager and was delighted when he was appointed director of the works department in 2013.

Carl Auger Mechanical Services Director

Carl began his career as an Estimating/Design Engineer for a large Oxford based mechanical services contractor. During his 4 year apprenticeship he obtained his NC and HNC in Building Services Engineering and completed his training in 2004.

Over the years he has continued to develop his skills while adding invaluable experience along the way. With an exceptional eye for detail and the desire for perfection, Carl has focused on a career in pre-construction working for some of the top contractors in London, being associated with some of London’s most recent landmark projects. His skills have enabled him to manage estimating departments responsible of securing circa. £50m of mechanical services contracts in a single calendar year. He has successfully worked on projects covering all key sectors such as Cat A/B fit out, commercial, high end residential, education and healthcare.

Having worked in London for the last 5 years, Carl decided to return to his roots and was appointed as Mechanical Director of GA in January 2015. His primary objective is to execute one of our long time goals, delivering mechanical services contracts in-house. Carl’s expertise in business development, pre-construction, estimating, design and 15 years experience in the industry will prove crucial in the success and continued growth of our mechanical services business.
