Scope of Works

• Severn Trent were re-developing the building the antennas were positioned on.
• The equipment room did not form part of the development area and would remain in situ.
• Our client had a stub mast located on the building which was shared with another operator.
• The short-term solution was to remove all active equipment from the building on to a temporary structure and re-jig into the existing equipment room.
• Works had to be completed on or before 6th April, 2018

Site Overview

The antennas were located on a building and the kit was situated in a ground-based, brick-built equipment room which was approximately 60 metres to the South East.

Proposed Solution

• We created a bespoke design for the temporary tower base using concrete ballast blocks due to its small footprint (4m x 4m)
• Critical to project success was working closely with the Other Licensed Operator (OLO) to ensure that the project ran to timescales.
• Deploy a 15m temp mast adjacent to the existing equipment room.
• Remove the antennas from the current site and re-rig them onto the new temporary structure. Run feeders into the existing equipment room.
• Space was limited and the only option available for the new structure was an old cabin base. The dimensions were only 4m x 4m.
• A temporary structure was sourced at short notice that would fit on the base.
• Due to the space restrictions an ‘ad hoc’ design was required. Clarke Telecom structural engineers produced a solution whereby concrete blocks were added as ballast to ensure the stability of the tower.

Challenges Overcome

Timeframes
Three-week project including Easter weekend site shutdown

Severe Weather
Heavy snowfall and high winds

STW Proceedures
RAMS / POW needed STW approval prior to site start

Site Conditions
The building the antennas were located on was part of an underground reservoir which restricted size / positioning of crane.
