Mechanical & Electrical Building Services Design
The design of heating, ventilation and air conditioning systems, domestic hot and cold water systems, above ground drainage, electrical installations, lighting, fire and security systems. The design of low energy heating and cooling installations, solar thermal and solar photovoltaic installations. The production of technical documentation which conform with the latest British Standards, planning requirements, CIBSE guidance and best practice. The production of the associated technical illustrations drawings which depict the mechanical and electrical requirements.
Building Thermal Modelling
Dynamic thermal modelling software is applied to new and existing buildings to establish the building’s projected thermal and energy performance, internal environmental conditions and overheating assessments.
Inspection & Supervision
Generally, checking and supervision duties are performed during the construction phase of a project to ensure the installation complies with the design intent, relevant guidelines including health and Safety guidance, good practice, British and European Standards. Commissioning procedures are witnessed, and results checked against the design criteria. Auditing of proposals from maintenance contractors to assess whether the proposed remedial work is required and of value.
Condition Surveys
Typically, a visual condition survey is used to assess the operational condition of existing building services equipment. It will include the production of a schedule of assets categorising them as high, for statutory or health and safety shortfalls, medium, for those requiring improvement, and low for future remedial work consideration. The equipments operational life expectancy is also included within a review, itemised budget replacement costs for operational staff to assess their anticipated maintenance expenditure over five, ten or a fifteen-year period.
Dilapidation Reports
Generally, dilapidation reports are carried out on behalf of landlords or their representatives to establish the building services cost to return their premises to its original state prior to the property being let to the outgoing tenant. Schedules of defects and damage to building services equipment are produced including maintenance issues to ensure the tenant is complying with the lease terms.
Life Cycle Costing
The assessment of the building services equipment initial cost, operational and maintenance and disposal costs, pay back period assessments for energy efficient equipment and renewable systems.
Service Design Checks
To ensure the assets meet the design intent and continue to operate satisfactorily which is assessed by visual inspections, performance testing and the review of empirical performance test and maintenance data.

I have known Kevin, the director of Kelly & Knight for a long time and had the pleasure of working with him on a range of different types of projects over the years. He is a genuine subject matter expert in his field, and he has always added huge value on projects we’ve worked on together through the advice he's provided. He is practical and diligent, and I thoroughly enjoy working in the same project team as him. Therefore, I'd have no hesitation in recommending him to others and have done that on several occasions recently.
