CTI Blog - Offsite: If it's not a System, then It's not a Solution

This guest blog post is by Gerard McCaughey, CEO of Entekra Inc

 

In Europe wood frame construction market adoption varies widely from virtually 100% in Scandinavia to 70% in Scotland and about 30% in Ireland and many other central and western European countries. However, what is common in all the countries, where wood frame is used, is that virtually all of it is constructed using an off site construction (OSC) system.

Most of the customers in Europe, whether they are builder/developers or custom home end users, understand the benefits that off site systems (OSC) can deliver in terms of speed, efficiency, quality, energy efficiency and sustainability. It would virtually be as alien to a European to stick build a wood frame house, as it would be to buy a new car and have every single component shipped to your front yard and have a couple of local mechanics come out in a pick up truck with welding equipment and pneumatic tools to build the car. You simply wouldn't dream of it.

Why ignore that 100 years of innovation and progress

Yet in the US market this is exactly how wood framed houses are built, without taking advantage of the last century of innovation and ignoring the benefits of computers, modern automation or factory controlled conditions and quality systems. The real question is Why?

Really the question is better phrased as why have off site solutions not been more widely adopted by the US construction industry?

Off Site System providers not component manufacturers

A large part of the reason is due to the nature of the "off site" industry in the US. In Europe and other parts of the world, the off site companies are part of a dedicated off site industry and categorically see themselves as offsite system providers and not as component manufacturers. In fact the term component is hardly ever used by the off site industry outside the US as the off site companies realize that the customer is not interested in purchasing components but rather is seeking a solution. The so called components are merely an output and form elements of a system which is a solution to the problem the builder wants addressed. They are not the raison d'être of the off site company.

Off Site benefits come from an integrated approach

Until there are dedicated Fully Integrated Off Site System providers it will be very difficult for the builder/developer to gain meaningful benefits and for off site solutions to gain a bigger share of the framing market. One of the major obstacles to this is the requirement for an experienced in house engineering team, as off site solutions will always be compromised if they are forced to use engineering that was designed for stick framing.

In particular, design, engineering and manufacturing of Pre Fabricated Floor Cassettes (PFC) requires a lot of internal engineering expertise. PFC's are are a critical element of off site construction in the multi-story , multi-family and light commercial markets. Engineering for maximum off site efficiency requires a detailed in depth knowledge of factory manufacturing techniques, structural engineering and the off site building process and connection detailing including sequencing and materials selection.

Until those in the industry with a genuine interest and vision for the potential of the "off site industry" realize that they need to become more than just component manufacturers and instead act as off site system/solution providers and resource themselves accordingly, the industry will fail to reach its potential, despite the the labor shortage, which is forcing builders to look for new solutions.

True off site companies are solution focused businesses that happen to manufacture components as an output of an integrated system that's purpose is to facilitate the fast track construction of a building utilizing both labor and material efficiency. Off site companies may manufacture components but they are not component manufacturers!

CTI Blog - Structural Timber Offsite solutions can massively help solve UK Housing crisis

This guest blog post is by Andrew Carpenter, CTI Director and Chief Executive of the Structural Timber Association (STA)

This feature is part of STA response to the launch of the Government Housing White Paper

 

As Sajid Javid outlined what he called ‘the bold radical vision for the housing market’ and the government’s commitment to support offsite factory built homes, the CTI and the STA firmly believe that offsite timber construction is the only way to reach the specified target of one million homes by 2020. We welcome the government’s commitment to act as a catalyst for change in the wider housing market, through supporting offsite manufacturing techniques.

With four out of five new homes in Scotland being built from structural timber – we know that offsite timber solutions address many government concerns associated with public procurement of housing including speed of build, environmental impact, lifetime energy efficiency and cost performance – these factors are all largely beneficial not only to government plans but to the wider community.

Offsite manufactured structural timber systems have advanced greatly in recent years and can offer house builders cost, programme and performance assurances. Structural timber solutions outweigh other sectors in regards to volume of materials – the sector is quick to respond and can add capacity at a relatively rapid rate to meet demand. Shortages in other traditional construction materials will continue to encourage larger builders and specifiers to look to alternatives.

Innovation in the structural timber product range has broadened the appeal – the industry is no longer defined simply by the supply of timber frame kits and panelised solutions. It is driven by intelligent and integrated construction solutions, such as closed panel timber frame, structural insulated panel systems and volumetric modular options. Manufacture in well managed factory conditions, with stringent controls in place - minimises waste and optimises both quality and productivity.

As the government pledge support for small and medium size developers, as well as initiatives for self and custom builders – in theory there is a lot of positive content in this White Paper. Making the planning system more accessible and releasing land that is currently in public sector ownership, will certainly have an impact but only time will tell how it works in practise.

The time is right for the construction industry to embrace innovative timber technology and offsite techniques to develop better buildings at a rapid rate to meet government targets, to overcome the shortfall in housing stock and produce energy efficient buildings - particularly important for the social housing and private rental sectors, together with home owners and occupiers.
