A ‘hole’ lot of fun in Biggleswade 🏗️
A week ago our very own @HollyPeirson attended a site in Biggleswade where ground investigation works in the form of 3 trial holes were being undertaken.
🥅 Holly’s goal:
To assess the condition, depth, and type of existing foundations in preparation for a proposed extension adjacent to the current structure.
🕳️ What’s a trial hole you ask?
Trial holes are typically hand excavated pits next to existing foundations, this allows us to examine localised areas and determine foundation depth and composition. This crucial step helps us understand potential impacts on existing structures and adapt our designs accordingly.
🧠 What did Holly learn?
Holly was able to gain valuable insight into the existing foundation at the site in Biggleswade. The investigation revealed masonry strip foundations approx. 1.0m below ground level, aligning with the building’s age and usage. With careful planning, our new foundations will be set at 0.75m in depth, avoiding the need for underpinning. We will also allow for a ground bearing slab which will be supported by the underlaying sandy soil which will be situated adjacent to the existing building, the reason behind this will be to minimise any surcharge risks.
We adopt this proactive approach to enable us to refine our designs at the pre-construction stage, saving time, costs and reducing environmental impact.
🤔 Still wondering if you should have a ground investigation?
Whilst there is an initial small upfront cost to having a ground investigation it is an investment that pays off. By possessing this information, we are able to design more efficient foundations, which in turn will save you and your client money PLUS reduce embodied carbon!
🌱 By understanding the soil beneath our feet, we are able to build a stronger, more sustainable future.
