Mechanical Estimating We will undertake your mechanical estimating for you. In order to compile your estimate we need you to forward your preferred specialist subcontractors; ductwork, thermal insulation, water treatment, testing and commissioning specialists. These are your discretionary sub-contractors. We will forward them relevant tender documents so they can produce the sub-contract prices for inputting into your mechanical estimate. We have a vast array of experience and knowledge of estimating mechanical services gained with major UK M&E contractors, ensuring you receive the very best estimating service whilst protecting your commercial interests. johnj on June 02 2009 00:00:00 ·
