Basement Impact Assessment
A Basement Impact Assessment (BIA) is increasingly required to be submitted to satisfy planning conditions imposed by local councils.
Working as part of a multidisciplinary project team, we provide assistance on all ground-related elements including the ground investigation. Soiltechnics has considerable experience undertaking all stages of a basement impact assessment on domestic and commercial basement projects throughout London. Led by a Chartered Civil Engineer we have a strong track record in helping our Clients attain planning permission.
In accordance with the guidance document produced by the London Borough of Camden and generally followed by other local authorities the assessment is typically structured into four stages:
- Screening – Following a desk study review of readily available information this stage identifies matters that require further investigation
- Scoping – Building upon the matters noted in the Screening stage, the impacts of those issues are identified
- Site investigation and study – This stage, if required, entails physical works at the site to confirm ground and groundwater conditions, and existing foundation depths
- Impact assessment – Detailed geotechnical modelling (Ground Movement Analysis) is undertaken to assess the impact on neighbouring properties.
What Our Clients Say
"Vision Survey have worked with Soiltechnics for several years, initially forging a strong working relationship with their Manchester office, which has since expanded to include our respective southern offices. We appreciate their excellent professional conduct, their collaborative working approach and ultimately, in knowing that we can rely on them to meet our requirements."
Nathan Pickering, Regional Operations Lead – Vision Survey
"I thoroughly recommend the expertise of Mark and the team – trustworthy and valuable advice in a quick timeframe for my project.”
A. Prior – Landowner
“Just wanted to say that I was very impressed with the site team this week. The site engineer showed great leadership on site, delivering the works on time, and kept us updated with daily diaries and updates throughout. The engineer also promptly provided me with certifications for all of the drilling rigs and equipment the guys were using without me having to ask for it, which isn’t typical of all of our subcontractors!”
Lewis Brown, Site Manager Projects – The Clancy Group
