The Chartered Institution of Building Services Engineers (CIBSE) has just released a. set of documents.

Digital files from the model can be sent directly to the fabricator.Certification to BSI and UKCA standards.

Fabrication of structures and components for structures up to 15 stories high using steel, aluminium and stainless steel.Execution Class 2 requires welds to be completed to ±0.4mm on steel and ±0.0 on aluminium.Certification is for the full factory control procedure including procurement, processing, fabrication, storage, Q&A and delivery with documentation at every stage.

Accuracy in pre engineered interfaces.The level of the bespoke design in traditional projects makes it difficult to properly design every interface, leading to variability between interfaces on-site and the need for ad hoc changes.

However, trades at different points in the process don’t necessarily have access to the early decision-making rationale, so there can be unanticipated consequences of these forced ad hoc changes.. For example, façade installers have reported that they spent 40% of their time undertaking site surveys and using shims and packers to fill in the gaps between their manufactured unitised systems and traditionally built superstructures.

This example is particularly pertinent given the crucial role façades play in fire stopping and compartmentation..Using P-DfMA, we can have both..

Flexibility in modular construction.At Bryden Wood, it’s a guiding principle that we never compromise the design to fit the system.

Rather, our aim is to allow a level of flexibility in the components to resolve the tension between the need for optimisation and variability – what the market wants, or clients need.For example, with the Platform to superstructure, we have a series of standard connection brackets, which link the beams and columns.
