As it dries it changes geometry losing original accuracy.
3D modules also occupy large amounts of factory floor space and therefore absorb a high proportion of factory overheads..If these additional modular construction costs can be offset by large improvements in construction site efficiency, for example by relocating wet trades or complex specialist trades away from the site, a 3D module might make sense.
But, with modular construction, it’s often the case that prefabricating comparatively simple parts of a building as 3D modules adds cost and complexity, especially if the required trades need to be present on-site anyway..The problems found in modular construction are only compounded by inefficient factory working.The cost of any prefabricated component (indeed, any component of any building) can be divided into materials and labour.
If we ignore the cost of the labour that has gone into making the component, we only have material costs left, resulting in limited opportunities to add value.Manufacturers have understood this for decades and spent a great deal of effort developing highly productive assembly routines that enabled the mass production, automation and commoditisation that fuelled the consumer age.. Too often factories are treated as ‘construction sites in a shed' producing bespoke, custom components with overlapping trades and poor works sequencing, causing reduced value and the same inefficiencies that are often found on construction sites.
We want the factories that produce components for the construction industry to be more like the best factories making consumer goods; highly efficient, controlled and focused on achieving the highest throughput for the lowest cost, without compromising on quality..
In short, we want factories to be less like construction sites.. Construction Platforms: our MMC approach to achieving the best mix of on-site and off-site construction.These projects were significantly different in form, conception and function, but common threads in the design and delivery approach helped both to achieve success and industry recognition.. Pfizer API, Singapore: efficiency and value.
This new API (active pharmaceutical ingredient) manufacturing plant is a flagship facility for Pfizer’s regional network, a $1bn SGD investment covering almost 430,000 square feet and delivered entirely during the COVID-19 pandemic.The facility needed to represent best practice in GMP (good manufacturing practice) and digital automation while remaining cost effective to build and operate.. Bryden Wood was engaged to review and optimise a previously developed concept design for the site’s dry processing (milling and sieving) building.
We worked closely with client stakeholders to analyse the root process requirements, identify over-provisions in the proposed design, and consolidate production onto less equipment.. Capturing these root requirements in 3D digital models called.“Chips” (sets of interacting components.
