Description/Key Delivery Features:
This contract was secured following a competitive tendering process by ABP at Alexandra Dock, Newport. The project comprised of the design and construction of a steel framed bulk storage shed of circa 6,000m2 (50mx 120m) as well as the construction of new and replacement access facilities to No 21 shed and to existing weighbridges alongside.
The works comprised of the design and construction of:
Steel framed shed including frame and cladding
Perimeter in-situ reinforced concrete retaining walls
Piled foundation works
Internal electrical distribution and lighting system
The diversion, protection or removal of existing infrastructure affected by the proposed works
New access road and weighbridge modifications.
The ground conditions required considerable strengthening work to be undertaken and circa 1400 precast concrete piles were driven to a depth of up to 20m, and cropped at ground level. Obstructions were encountered resulting in an additional 48 piles being inserted.
Jones Brothers were appointed as Principal Contractor. The contract required the services of several specialist subcontractors and the effective coordination of work activities. This was facilitated by daily ‘start of shift’ briefings. Early interaction with design team resulted in the construction programme being reduced the by 8 weeks. The project demonstrates our ability to work collaboratively with our design partners comprising of Bradley Associates and CMB Electrical, the Principal Designer and the Client which resulting in the project being delivered 8 weeks early.
Challenges and Solutions:
The reinforced concrete retaining wall peripheral structure was designed to accommodate three number concrete pours. Through early innovation with the design team this was simplified to two pours and in order to expedite work we assembled wall base reinforcement cages off site and slotted into place on site by forklift.
We recognised the importance at an early stage of the impact of the works on ABP interests as well as other stakeholders. We prepared a stakeholder management plan and ensured that through regular dialogue we ensured that their operational needs were not compromised at any time. Phased road closures were agreed with ABP and were diligently followed at all times. The dockside environment demanded extremely onerous environmental controls. Particular attention was given to the containment of concrete wash-down areas.
