Background
Hambridge Homes Limited commissioned us to conduct an air quality and dust risk assessment and develop a Dust Management Plan for the project approved under application DC/22/127431.
This project involves the demolition of two existing dwellings and the construction of a four-storey building with a roof terrace, providing 16 self-contained flats at Taymount Rise, SE23 3UL. The development also includes accessible parking spaces, cycle and bin storage, amenity space, a play area, and landscaping. The site falls under the jurisdiction of the London Borough of Lewisham (LBL).
Our Approach
Air Quality and Dust Risk Assessment
Our assessment aimed to identify the risk category for dust emissions during the demolition, earthworks, construction, and track-out phases. We developed a management and mitigation strategy to control and reduce negative impacts and adverse effects. Dust from these processes can contain various particle types and sizes that pose health risks and cause surface soiling.
The primary pollutants of concern were PM10 and PM2.5, which are respirable particles that can penetrate deep into the lungs and cause health issues.
The initial step was to conduct a screening to determine if a detailed assessment was necessary. A detailed dust risk assessment is typically required if there is a human receptor within 50 meters of the site boundary or the routes used by construction vehicles on public highways, up to 500 meters from the site entrances, as was the case here.
The detailed assessment enabled us to propose appropriate dust and air quality mitigation measures, which were then incorporated into the Dust Management Plan.
Project Progress
Lewisham Council approved the details reserved by Condition 5 (Dust Management Plan) in June 2023.
