Bmech Services has recently completed the total refurbishment of the LTHW, Boiler and Hot Water Services in the famous Manchester building; The Corn Exchange Shopping Mall.

 

Known as 'The Triangle' until recently, this famous Manchester landmark is a beautiful, history-rich grade II listed building.

 

Due to the site only having one of three existing boilers operational and the dilemma of this boiler constantly leaking and the worry of a cold winter on its way, the rush was on to have the new boilers installed ASAP.

 

Bmech were given a very tight timescale to carry out the works with liquidated damages to be received if we do not hit this deadline.

 

Within days of winning the tender, Bmech were on site to decommission two of the three existing boilers.


Removal of twelve tonnes of boilers from sub basement level was no problem for Bmech’s experienced team of engineers. Various enabling works were carried out to be able to remove these boilers including the creation of a new fire rated roller shutter door to allow access from sub basement to basement level. As when dealing with a building of the Corn Exchanges age, there was always going to be unforeseen issues and one of the main ones was the failure of the existing flue system when under test.

 

Bmech were then instructed to replace three no. existing 450mm flues, through 7 stories and terminate above the roof line. To add to this issue, there was no access to the flue riser on any level and Bmech had to install new fire rated access doors on each of the seven levels to access the existing flue for removal, all carried out of normal hours. Two of the three new boilers were delivered, installed and commissioned as to programme. Once proved, the exiting boiler was removed and the final new boiler installed. Various alterations to the pipework was undertaken and new 6” gas main installed.

 

To add to the works, alterations to the existing hot water services was undertaken. The existing provision of hot water was by means of a plate heat exchanger using the LTHW as the medium. As to spec, Bmech installed two new gas fired hot water heaters complete with new stainless steel pipework and new flue system, gain through 7 stories all carried out during out of normal hours.

 

Bmech managed to complete the project on schedule, and on budget which due to the extra issues that arisen on site, we are very proud of.
