Data Centre marine Construction Week 2
Data Centre Construction Project
The project was awarded under a JCT (Joint Contracts Tribunal) works contract and included penalty clauses or LAD's (Liquidated & Ascertained Damages) so it was vital that the project finished on time and on budget to meet the organisations data centre migration plans. INFINITI was appointed principal contractor for CDM (Construction Design Management) purposes and will liaise with the client appointed Contract Administrator and CDMC (Construction Design Management Coordinator) throughout the duration of the project.
This blog will cover the full data centre construction process spread over an 8 week duration and we will be providing you with a detailed insight that covers the implementation of a data centre facility from design approval of detailed construction drawings and initial strip out right through to final commissioning, witness testing, project completion and handover to our client all within an aggressive 8 week programme. All works have been undertaken within a completely live and busy office building environment.
The design ethos of the data centre facility is scalable and offers our client a complete flexibility with future expansion and will accommodate 100% growth if required, but still ensuring losses are kept to a minimum and that the data centre is as efficient as possible even at lower initial day loads.

Week 2 - Demolition & Construction of Modular Data Centre Composite Walling
Following successful completion of the strip out and building services diversion works, INFINITI engineers began the removal of walls that segregated the office, meeting room and storage areas to form one large open space. Please note that all demolition works were carried out within a live normal operating office environment. To ensure the safety of contractors and staff working within the building, INFINITI's data centre construction project managers provided a detailed project plan which highlighted risk and times for all noisy works. Routes for egress and access for contractors and waste were also agreed as part of the Construction Phase Plan. As part of the CDMC compliance and INFINITI's waste management policy, positions for skips and waste were agreed with the client as several are now needed to avoid the cross contamination of waste
The terminal room originally housed the old main frame computer room and during the removal of stud walling legacy sound proofing and other acoustic materials were found and needed to be removed to ensure sufficient space was available to accommodate the overall footprint and layout of the new data centre design.
During the site survey, it was noted that the existing concrete blocks were a non-standard size and we would need to ensure that a certain amount could be clean, reclaimed and recycled to block up doors ways. Where possible, existing containment and brackets were also recycled to minimise the amount of waste generated from the data centre construction project.
Once all the demolition works had been completed and final remaining building services such as the ducting and air-conditioning systems had been removed, we began the installation of the MDC (modular data centre construction). The MDC is made of up of 1 hour fire rated composite walling panels which interlock to give an almost air tight seal. The panels are made up of compressed rock wall at 100mm thick and then finished either side with a 3mm powder coated steel finish.
The benefits of the MDC design are the LPCC (Loss Prevention Council Certification) certified 1 hour fire rating, sound reduction properties by up to 40db, rapid installation without the need for wet trades and minimal dust which makes this design approach and product ideal when working in operational buildings and office environments. The installation of the MDC walling was completed within 3 days from delivery
