Cundall, an engineering and sustainability consultancy, has produced an independent comparison of the embodied carbon between the traditional and P-DfMA designs, and found a 19.4%* reduction in embodied carbon per m. 2. in the P-DfMA design, a 36.4% carbon reduction in the substructure and a 20.21% reduction in the superstructure and facade..
This resulted in, for example, designs that were highly optimised in terms of layouts, space allocation, adjacencies and functional flows – which could then be deployed across the PETP programme and wider prison estate.It creates further efficiencies.
For example, the standard building types can be used across a range of sites.For each, the site-specific design activities can be focused on the placement of the buildings relative to each other, arranging orientation to minimise overlooking and overheating (for both the comfort of prisoners and to reduce energy use), maximise views of landscape, and so on.It contributes to overall better design and allows designers to focus more of their efforts on solving the specific challenges relating to a particular site and context.
Standardised solutions lend themselves to efficiencies in construction and the application of DfMA.Operational benefits.
Standardised solutions facilitate efficient operation and maintenance, as well as aiding staff and prisoner wayfinding and navigation.. A developmental process, an evidence-based approach.
Bryden Wood had been working with MoJ since 2011, when we helped developed their BIM Implementation Plan.There is a paradox; what does long-term planning look like when there is little clarity on how individual technologies will deliver or develop?
How do we demonstrate clear business cases for investment when many approaches are not yet ready for deployment and those that are ready have not been tried and tested?.There is also a significant cultural change to work through as activities which were previously seen as high-value, almost crafts, become commodity services..
There is clarity in the fact that changes in equipment and technology will have significant impact on buildings, structural loading, vibration control, floor-to-floor heights and special layout.. Less quantifiable is how buildings will need to change to support the change in the people operations of scientists, engineers, technicians and managers.Laboratories can be sited in warehouse or industrial zones which could serve the need of building adaptability very well..
