CASE STUDIES

Blyth Substation Land Remediation Case Study

The project began with a watching brief, followed by comprehensive testing and analysis after asbestos was identified in physical samples. Treatment of the topsoil and subsoils was conducted in two sequential phases, resulting in 4,200 tonnes of contaminated soil being transported off-site to Augean Waste Soils Treatment Plant. After treatment, the soil was deemed reusable, preventing it from being sent to landfill. The entire 2.75-acre (1.11-hectare) site was designated as an asbestos zone.

National Grid Upper Boat 275Kv Substation

Balfour Beatty commissioned Phase 1 and Phase 2 land remediation investigations, followed by asbestos land remediation work. A comprehensive suite of tests was conducted across the site using a 5m x 5m grid to develop a thorough sampling strategy, culminating in a detailed report.

To facilitate safe operations, haul roads were constructed, and scaffolding with decontamination facilities was installed for the loading and containment of tipper lorries, along with a wheel wash station.

Temporary works included propping the existing 33kV cables and excavating around them to enable safe access for APS.

An Asbestos Management Plan (AMP) was developed throughout the project and incorporated into the site’s Health & Safety file for handover to the client.

London Power Tunnels

Designed and installed temporary works, including a hermetic seal, to support air management within the 26km tunnel. Additional sealing and fire-stopping measures were implemented throughout the 7-year project to ensure long-term safety and functionality.

New Holland Tractor Plant - Basildon

Emergency asbestos cleanup and removal were conducted following a roof integrity breach, which caused a leak and resulted in asbestos insulation falling to floor level. After the initial cleanup, scaffolding was erected, and the high-level area was fully decontaminated, with all lagging removed

Luton & Dunstable Hospital
CDM Case Study

The project involved asbestos removal and remediation within the confined underground duct system spanning the hospital's footprint, with LAR serving as the Principal Contractor under CDM 2015 regulations. Work began in September 2019 and has continued through the COVID-19 pandemic, ensuring the provision of critical services, including medical oxygen, without any disruption to hospital operations.The team successfully navigated challenges such as COVID-19 restrictions, flooded ducts, live services, damaged high-voltage cabling, extended project scope, and out-of-hours work. Additional efforts included accessing unknown ducts outside the original contract, creating entry points through external walls, and installing lintels and frames to accommodate new access doors upon project completion
