I carry out M+E and fabric surveys and although this is a bit of a plug i will also explain what a condition survey is to those who are unaware.
When carrying out a condition survey its main focus is in identifying the condition of assets. In the Mechanical and Electrical condition surveys (M+E). This could be identifying things like has the maintenance been carried out and to an acceptable standard. Is the equipment operational and in good working order. How soon would the equipment last before it needs replaced.
Does the equipment sit in or out of scope? E.g. a contract may say all things are in good working order but you discover many items are failing or outside of compliance and regulations. E.g. an electrical isolator may be 50 years old but its replacement would also lead to an entire rewire from where it was originally fed. This needs to be identified as a risk and to be removed from scope or an adjustment in budget to cover its costs.
Fabric is similar because although its not pumps, motors and air conditioning. It does have things like periodic refurbishments and repairs. This means things like mold that can cause paint flaking and health issues are a problem. As well as ground movement cracking walls etc. which can often see written into a contract what is defined as a chargeable crack and what you should expect to absorb within the contract at no extra cost.
All these things affect building a contract for maintenance and as such its a critical part of renewing a contract or setting one up. It gives a realistic view of the business and all its assets as well as identifying any assets that are missing from the system completely.
