warranty

During the course of electrical estimating we have noticed there seems to be overkill these days in consultants specifications for  what they require for handover, are use the word THEY, because these are standard general specification clauses that are in the consultants standard speciation’s without thought or consideration to what the client might need or require. They often have a list of items they require in an M&E Operating and Maintenance Manual that are irrelevant. For example is, provide warranties for equipment supplied. Warranties seek to do the opposite of what they imply. A manufacturers warranty will limit their liability for repair or replacement or consequential loss should the goods fail, further more the warranty is given to the purchaser of the goods and cannot be relied on by the third party, the customer.

The warranty cannot be called upon by the customer because they are a third party. unless the warranty uses the phrase, “third party rights” . There will also be a condition of proof of purchase to be able to claim on the warranty The customer is reliant on the specifier selecting reputable and reliable goods in the first place. The specified supplier will normally enforce their own commercial conditions on the customer, and being specified the Contractor has little barging power, nor is it likely the warranty wording can be changed.

Another example when electrical estimating is faulty finding guide, asking the contractor to provide a fault finding guide, this is impractical and naturally limiting and potentially lethal. To believe that the manual can anticipate all faults that may occur then write a guide on finding and curing them ignores the fact that the services are complex and should not be interfered with by a novice. The person finding fault and curing it should be a competent person, in Amendment 3 of BS7671 2008 17th edition this is recognised, 134.2.1 appropriate inspection and testing shall be carried out by skilled persons competent to verify that the requirements of this standard have been met. If you write a fault finding guide their is a high risk that a none skilled and competent person will attempt to fault find and cure the fault. A skilled and competent person wouldn’t need a fault finding guide to the installation, just a good operating and maintenance manual that has schematics and record drawings , test results, manufactures and part numbers and maintenance schedules. irrelevant.
