Colin started as an apprentice design engineer with Norris Warming Co (now part of Staveley Industries) in London and after completing his training moved to the Bristol office where he was responsible for major installation projects. He then became the Manager of a firm of refrigeration engineers in Bristol where he gained substantial experience not only in marketing but also refrigeration equipment design and installation.

There then followed a period of three years in the Middle East running major projects including a leisure centre, the Rulers' Palace, a Municipality Administrative Headquarters. He also was in charge of a construction company plant and transport department with responsibility for all construction plant and the transport fleet.

On completion of these contracts he returned to MJN in Bristol and was involved in major projects for both Bath and Bristol Universities, Ministry of Defence Establishments and commercial developments.

There followed a period as General Manager and Director of a small contractor based in Wiltshire where his role was to assess the viability of the company and report to the board of the holding company. This resulted in a rationalisation of the groups contracting activities and closure of the firm. Colin spent two years with Haden Young in Southampton as both Contracts and Design and Build Manager. During this time he was responsible for the Haden part of the Joint Venture with John Laing Construction for the construction of Dorchester District Hospital.

For six years prior to the formation of DAVIES ASPIN PARTNERSHIP he was Chief Engineer and County Energy Manager for Avon County Council responsible for the design of new projects and the maintenance of services installations in over a thousand buildings with an energy budget of almost £9m a year.

Since the formation of his partnership with Norman Aspin, he has been increasingly involved with the Construction Industry Standing Conference (CISC) developing National Vocational Qualifications. As a consultant to the Building Services Development Group (BSEDG) this work has extended into the building services field. He is, now, an Assessor for a Level 5 National Vocational Qualification in Construction Project Management and a Verifier for a number of building services qualifications
