PROJECT BREAKDOWN
To facilitate the delivery of the new extension and supporting infrastructure, Tilbury Douglas appointed STOCKTON GROUP to deliver the civil engineering package, encompassing substructure construction, drainage infrastructure, and associated external works.
DRAINAGE DELIVERY
The project required the installation of an extensive below-ground drainage network, incorporating foul and surface water systems, hydro break manholes, and a small attenuation tank to regulate discharge rates.
These elements formed part of a coordinated Sustainable Drainage System (SuDS) strategy, with porous surfacing integrated into the car park construction to manage surface water effectively and mitigate flood risk while ensuring long-term durability and performance.
REINFORCED CONCRETE AND SUBSTRUCTURE WORKS
Substructure works included reinforced concrete pad foundations, ground beams, and a ground-floor slab with integrated heave protection. All concrete works were subject to structured testing to ensure compliance with specification and performance standards.
Excavation works identified an uncharted gas main, which was immediately safeguarded and incorporated into revised working methods to ensure safe continuation of the works.
HEALTH, SAFETY, AND ENVIRONMENTAL COMPLIANCE
Stockton’s Health, Safety, Quality, and Environment (HSEQ) procedures were implemented throughout the project. An external HSEQ auditor conducted regular site inspections to monitor compliance, and Stockton achieved full adherence to health and safety requirements throughout.
Environmental controls were maintained throughout, including tree protection measures, fuel spill kits, drip trays, and designated concrete washout facilities to prevent contamination.
Despite operating under strict Covid-19 restrictions, the project was delivered on schedule
