The off-site advantage

Just like other advancing industries, the proliferation of new technology shapes the efficiency of construction projects. DfMA elements can be created using the same materials and design codes and standards as conventionally built projects, or new materials and design standards may be developed.

In some cases, up to 90 percent of individual DfMA elements can be completed on the factory floor. This practice produces a greener, faster and smarter outcome with:

  • more flexibility
  • cost predictability
  • shorter schedules
  • safer construction

Time savings

DfMA can produce a quality product in up to half the time of conventional on-site construction.

Building with DfMA elements avoids unpredictable weather and site conditions causing delays. Off-site construction allows tasks to be conducted simultaneously instead of multiple trades competing for space.

Stronger structure and better quality control

DfMA buildings are generally stronger, as each DfMA element is engineered to independently withstand the rigours of transportation and placement.

Factory construction also enhances control and consistency as efficiencies are maximized while avoiding on-site risks like workmanship, site congestion and bad weather.

Improved safety

Removing up to 80 percent of construction activity from the site reduces disruption and traffic while improving overall safety and security. Factory production is more predictable and eliminates risk factors:

  • weather
  • difficult access
  • unprotected work areas which

This results in less errors and general hazard avoidance.

Greater sustainability and waste reduction

The need for friendlier building practices is on the rise along with the push for more sustainable building materials.

According to the Waste Resource Action Program, producing a DfMA modular-based building uses only 33 per cent of the energy of a conventionally built project. This is a result of leveraging a controlled environment.

In addition, the reduction of material waste, noise, dust and societal disruption associated with DfMA improves sustainability.

The technological potential

From advanced robotics and automation to building information modelling (BIM), off-site construction is primed for technological gains.

Using BIM means that an accurate virtual model with precise geometry can be constructed to perform a number of processes like:

  • visualization
  • modelling
  • code reviews
  • cost-estimating
  • construction sequences
  • conflict and collision detection

Off-site can also integrate technologies into the end product for a ‘smarter’ built environment.

Logistics and shipping

DfMA elements are designed for the logistics and transportation required on most project sites.

DfMA elements fit containers for marine shipping, rail cars and truck trailers, allowing manufacturing and shipping from distant locations.
