The Ultimate Chromebook Buying Guide
Having spent many years in projects I realised that our allocation of work is so often skewed by a mode of thinking and processes that ultimately destroys value.
The use of screeds, which are bound to the surface of timber and structural fixings also make it difficult to dismantle and reuse.. Long span engineered timber elements also undergo non-reversible long-term deformations that can limit its feasibility to be reused as a structural element.However, upcycling of these elements is still a viable solution.. Our response is to:.
- Engage early with contractors to plan deconstruction scenarios and reduce waste sent to landfill.. - Adopt circular economy strategies for deconstruction and reuse, including:.o Upcycling materials to put back in the local supply chain.. o Adopting the principles of buildings as material banks, urban mining, and use of material passports.. o Using bolted connections and smaller structural grids, which facilitate disassembly, cutting (if needed) and deconstruction.. Use membranes to decouple the slab from the screed and explore alternatives, such as dry screeds, sand and gravel screeds, floor dense boards, particle boards or cardboard and sand layers.. Procurement of timber and distance.Currently, most timber used in the UK for construction is manufactured and imported from mainland Europe.
Depending on the distance, this can have an impact on the total carbon emissions.. Our response is to:.- Conduct detailed whole-life carbon analysis of buildings, including harvesting, processing, manufacturing, and transportation to end-of-life disposal.. - Prioritise locally produced engineered timber and strategically select timber that can be shipped instead of transported by road.. At Bryden Wood, we have explored local sourcing of engineered timber.
The results show that distance is very important and the carbon emissions from northern France, Belgium and western Germany are relatively small.
In the case of Spain or Sweden, even though these materials can be shipped by boat (lower carbon emissions per nautical kilometre), the distances are so large that they amount to more than double the emissions from road only transportation.While working on the Reducing Invalid Planning Applications project (RIPA), Ricketts began to map all of the legislation and planning policy, turning it into rules-based code.
He wondered whether it could be used to map against BIM models, in order to extract all of the relevant information that planners need to assess and develop a decision.The aim would be to extract only the relevant pieces of information, out of the hundreds of thousands of bits of information in a BIM, leading to the question of how to present it for successful interpretation.
This is where his second project, Back-office Planning Service (BoPS), comes in.BoPS would take the information and present it to the case officer.
