This mechanical piped-services project was worth over £420,000 and peaked at over 30 tradesman on site, from MJG, in order to meet programme.

The works within an operational hotel and very busy up-market residential area, were completed in approx 4 months.

This contract was placed with MJG by Southampton & London based Heating, Ventilating and Air-conditioning (HVAC) contractor Working Environments Limited.

The project was primarily plumbing and heating and cooling system modifications, but also included gas services to the kitchens.

This project was for the supply and management of labour and materials for the installation of Mechanical Services including low temperature hot water (LTHW), chilled water, hot and cold water systems and above ground drainage.

As part of an ongoing refurbishment programme to relocate ‘back of house’ services to mezzanine and basement levels, these works were mainly associated with installation of a new staff restaurant, offices, laundry, changing rooms and other back of house areas.

The works were executed while the hotel was fully operational, so to achieve minimum disruption, the necessary shut-downs were completed out of normal working hours.

Space heating was provided by a combinationof Fan Coil Units, under-floor heating and anAir Handling Unit. The Landlords LTHW and Reclaimed LTHW branch connections were extended to suit the new design.

Cooling was provided the Landlords system,MJG connected to the branch connections and extended the system to Fan Coil Units and an Air Handling Unit.

The LTHW and CHW systems were primarily installed in black heavy grade steel pipe and mallable iron fittings. Hot and cold water services were primarily copper pipe withsoldered capillary.
