McLellan is able to provide concept and feasibility studies leading to design, specification, installation and supervision of both mechanical and electrical plant and equipment.

We can also offer inspection and technical audit services designed to identify potential problem areas and highlight any deficiencies in the condition, efficiency or suitability of the existing equipment.

McLellan has often been called upon to diagnose why particular items of plant and equipment have failed and can apply forensic mechanical engineering analysis techniques to find the true cause of failures.

McLellan operates within the framework of an environmental policy which embraces all aspects of design including minimising fuel consumption and emissions. In providing design and engineering solutions, we take into account the capital as well as the whole-life costs of plant and equipment, and advise our clients of the most suitable and cost effective solution.
