M&E Lifecycle and Whole Lifecycle Management

Streamlining your mechanical and electrical lifecycle costs

The M&E lifecyle and whole lifecyle are two key elements of any contract for both the client and OCS. Through our expertise and experience, we are well placed to both advise and manage these two key areas on behalf of our clients. 

Lifecycle costs are the combined total of capital and revenue costs for an item of plant or equipment throughout its useful life and represent a significant cost to any organisation. 

The capital costs of building services systems are a combination of the initial capital costs, discounted replacement costs and any residual value (scrap) of items of equipment or other components of the system. The revenue costs are made up of the energy costs, planned and unplanned maintenance costs and the costs associated with consequential losses resulting from plant failure, such as loss of occupant productivity or production plant downtime.

Established lifecycle costs for particular items therefore have a number of uses and benefits:

  • Support design decisions regarding the selection of systems and their components
  • Aid decisions as to whether to repair or replace specific plant items at a given point
  • Select the most appropriate and cost effective maintenance regime
  • Appraise the effectiveness of a plant or system at the end of its life with a view to future replication of the desirable features, such as ‘designing out’ maintenance activities, reducing or eradicating unplanned downtime, improving reliability and avoiding excessive maintenance expenditure

Whole lifecycle is based on the evaluation of a number of additional parameters and the process of evaluation should highlight the best commercial, social and environmental solution for a given function over the life of a building, by helping to reduce wasteful processes and inefficiencies in specific aspects of its design, construction, maintenance, and refurbishment.
