MidCity Place

AHU & CHW Infrastructure Upgrades

Our engineers have completed multiple projects within live environment of MidCity Place. Our works have included AHU “pod” upgrades, chiller replacements, and CHW infrastructure upgrades.

The initial set of works at MidCity Place was a multi-phase chiller replacement project using state of the art energy efficient chillers. We carried out a full energy audit and design review as maximising efficiency was paramount to the client. Project works included a new site wide water filtration and treatment system and upgrades to the existing heat pumps.

Our project team created a detailed phased changeover methodology, which risk and fall-back planning, to prevent the loss of any cooling services throughout all parts of the building whilst our works took place.

Crane lifts were organised and co-ordinated to allow the removal of an existing chiller to coincide with the delivery of its replacement. Our enhanced programme enabled us to maintain operation of 3 out of the 4 chillers at any one time.

Because of our excellent delivery and risk mitigation procedures we were retained to undertake works to the AHU “pods” located upon the roof. Each “pod” contained an AHU, CHW coils and circuit, a boiler, a BMS system, and associated services to provide environmental control in a single package.

Our engineering staff co-ordinated the modification of the structure of each AHU “pod”. We enabled the installation of new, larger cooling coils, and then managed the full refurbishment of each AHU, keeping the AHUs live and partially operational as the works progressed to completion.

East West Connect have completed a logistically troublesome project with multiple plant changeovers without impacting the daily lives and operations of building users.

Hurley Palmer Flatt (now HDR)

We were initially appointed at MidCity Place to provide an emergency temporary chiller when an existing unit failed.

Our staff utilised their strong relationships with TfL and City of Westminster Council to arrange for a crane lift and chiller delivery within 2 weeks of appointment, preventing the building from overheating during the summer period.

Relationship building was key throughout the project. It was these strong relationships that allowed us to agree services shutdowns with both Hurley Palmer Flatt and the building’s operations team 2 weeks in advance. During one of our project workshops, our engineers ran through the scope of the shutdown so the on-site operations team could fully understand which services would be out of use.

When re-commissioning systems and bringing them back online, we ensured that all testing of new plant had been completed, and that any system livening up took place out of hours.

We worked with the incumbent BMS contractor to ensure that our new works were compatible with the building’s existing BMS. We integrated the BMS contractor into our team whilst procuring the new plant, ensuring compatibility and client confidence.

Off-site pre-fabrication reduced install times and hot works requirements on site.

All new pipework was pre-fabricated by our mechanical operatives at our off-site fabrication facility and delivered ready for installation. Along with the use of our London depot where the new cooling coils for the AHU “pods” were stored, this allowed us to minimise the number of crane lifts, and speed up the on-site installation process.
