05 Design & Delivery Systems / Worked example

A factory that ships in containers

A global pharmaceutical client needed manufacturing capacity in emerging markets, where construction safety norms were poor, local supply chains immature and logistics difficult. Building a conventional factory in each location meant long programmes, high risk and variable quality.

The answer was to stop designing buildings and start configuring products: a catalogue of components, authored once as content, configured into each facility, made in factories, shipped as standard freight and installed by a small multi-skilled team. A full-size prototype was built to prove the system.

Anonymised. Figures are from the published project account (UK construction trade press, 2016). Role: client-side integration, from design through manufacture, logistics and assembly.

Step 01 of 06

Author the catalogue

Each component is created once as a piece of content: its geometry and interfaces, performance, cost and carbon, where it is made, how it is installed, and the labour and training it needs. The catalogue, not any one building, is the asset.

What it removes. Designing the same thing again on every project. Content is written, checked and approved once, then reused.

Step 02 of 06

Configure, don't design

A facility is configured from catalogue content using rules for interfaces, clearances and regulation. The same configuration produces the layout, quantities, cost, procurement schedule and work packages at once.

What it removes. Design time and estimating uncertainty. A reliable cost for a new configuration takes days, not months.

Step 03 of 06

Make it in factories

Structure, panels, services and clean-room modules are made off site by specialist manufacturers, each to its catalogue specification.

What it removes. Weather, variable site workmanship and the need for a mature local construction supply chain at the destination.

Step 04 of 06

Kit, sequence and ship

Components are kitted into standard containers in the order they will be installed, and move by sea and road like any other freight. On arrival the container is the site store.

What it removes. Searching, double handling, abnormal loads and waiting on site.

Step 05 of 06

Assemble with a multi-skilled team

One small team, trained across structure, envelope and services, installs the whole kit using the methods written into the catalogue. The training is catalogue content too, so the team moves from site to site and gets better each time.

What it removes. Trade-by-trade handovers and the waiting between them, and dependence on scarce local specialist trades.

Step 06 of 06

Feed it back into the catalogue

As-built data, defects, lessons and improvements go back into the catalogue under version control, so each deployment starts from a better product than the last.

What it removes. Learning that stays with one project team and leaves when it disbands.
The honest trade-off

It is not cheaper than everything

Most DfMA case studies report only the wins. This one also reports the premium. Against the same pharmaceutical-grade facility built conventionally, the estimate was about 30% cheaper. Against a standard local building it cost about 15% more. Both are true, and which one matters depends on what the alternative really is.

The wider idea

The same system at programme scale

The factory in containers is one application of a wider idea: content authored once, configured many times, made in factories, installed by teams trained on it, and improved with each use.

Research on Heathrow Terminal 5 found that much of a megaproject’s production is made up of discrete, routine and repetitive processes that can be progressively standardised and replicated, and that performance improves when proven processes are recombined and replicated rather than reinvented[1].

In the water sector, Anglian Water replaced bespoke, site-built pumping stations with a configurable product platform: project teams select and adapt a standard design for the pumping capacity they need, and it is manufactured off site. Its manufacturing partner reports costs over 35% below traditional build and no accidents [2].

A pharmaceutical plant, an airport terminal and a network of water assets look nothing alike. The delivery system underneath them can be the same: a catalogue, the rules to configure it, a supply chain that makes to it, and multi-skilled teams that install it.

When it makes sense

Where assembly beats construction

  1. The same products are needed in many places. The catalogue and its content are an investment; repetition pays it back, across one programme or many.
  2. The destination is hard to build in. Weak safety norms, scarce skills or an immature supply chain make site work slow and risky; factory work avoids most of it.
  3. Speed to capacity is worth money. Weeks on site, not months, bring production forward.
  4. Quality has to be proven. Components made and checked in factories, with a data record for each, are easier to qualify than site-built work.
  5. Where it does not: a one-off building, a strong local supply chain, or a route that cannot take the loads. Then the up-front cost of the system may not be repaid.
