St. Bernard's Gate, Ealing

I-MEX (M&E) Ltd undertook the full design, installation and commissioning of the mechanical and electrical services for 270 residential units inclusive of private, shared and affordable units, working in collaboration with Higgins Construction Plc to deliver the scheme for Catalyst Housing Group.

As part of this development, I-MEX undertook the detailed design and installation of the site-wide energy centre, serving each of the five residential blocks.  The energy centre, containing modulating boilers serves a district heating system before supplying LTHW services to the heat interface units within each block.

As part of the tender process, I-MEX worked closely with Higgins to develop a robust cost plan at the earliest opportunity, providing best value for money by testing the supply chain at various stages within the pre-construction period.  Furthermore, during the design development period I-MEX highlighted a number of value engineering options, such as rationalisation of the plant rooms to create a centralised plant room serving the 5 residential blocks.  This design review led to a saving on the M&E services of circa £250,000.  I-MEX formed a crucial part of the delivery team, working in partnership with Higgins and their supply chain to deliver the units ahead of schedule.
