Large warehouse and offices

The client brief

Our client needed this large purpose-built distribution centre comprising over 500,000 sq. ft. of warehouse space and 20,000 sq. ft of office space ready to use in a matter of weeks.  The brief called for highly resilient design to support a 24x7x365 operation. Throw in a pandemic lockdown and it was going to be tricky.

Our solution

Two main comms room were connected by single-mode fibre running 40Gbps virtual stack link between a pair of Cisco Catalyst 9400 chassis switches. Each comms room was fitted with redundant 10KVA Uninterruptible Power Supplies with three-phase input. 20 outlying wiring closets were installed and fitted with Cisco Catalyst 9300 access switches, with each cabinet linked back to the main comms rooms by diversely-routed multi-mode fibre. Over 850 data outlets were installed to support equipment around the site, including 82 Cisco Catalyst 9100 Series wireless access points.  To achieve the client’s ambitious go-live date we worked alongside other contractors installing wide-aisle and VNA racking, CCTV, PA system, electrics and fire systems.

Risks and challenges

  • Coordinating our work with other contractors and managing multiple dependencies.
  • Working to an ambitious go live date
  • Work had to take place while racking was being built, which required careful coordination with other contractors to maintain safe working areas.
  • All work needed to be documented in advance so it could be cleared through the Client’s change control process.
  • Working at heights
