To support the expansion of facilities at Allerton Grange School in Leeds, a new extension and associated car park infrastructure was commissioned as part of a wider development led by Tilbury Douglas.

STOCKTON GROUP was appointed to deliver a range of civils works, undertaking a comprehensive scope of works including substructures, drainage, reinforced concrete, and full construction of the car park. The project required a coordinated, multi-disciplinary approach to ensure safe, compliant, and timely delivery within a live educational environment.

SCOPE OF WORK

SCOPE OF WORK

The project involved comprehensive groundworks and infrastructure delivery, spanning site establishment, survey control and cut-and-fill operations through to drainage systems, reinforced concrete construction, external works and final reinstatement.

Works centred on substantial substructure and reinforced concrete elements, including pad foundations, ground beams, and a ground-floor slab with integrated heave protection. Extensive foul and surface water drainage was installed, incorporating hydro break manholes, a small attenuation tank, and Sustainable Drainage System (SuDS) components such as porous tarmac construction.

External works completed the scheme, including kerbing, paving, steps, footpaths, and full car park construction with white lining, alongside street furniture installation, temporary haul road formation and site-wide earthworks.

Project Breakdown

Live educational environment

Works were undertaken within an operational secondary school, requiring strict segregation, phased working, and controlled site access.

Sustainable drainage strategy

The development incorporated the installation of hydro brakes, attenuation systems, and porous surfacing to control surface water and reduce flood risk.

Complex below-ground infrastructure

Installation of foul and surface water drainage networks, including attenuation tank construction and associated manholes.

“Delivering this project within a live school environment, while keeping on schedule under Covid restrictions which were in force at the time, required strong coordination across multiple civils disciplines. The team responded professionally to every challenge, including the discovery of an uncharted gas main, ensuring the works were completed safely and to a high standard.”

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.

 

PROJECT BREAKDOWN

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
