Design & build the way forward

But this isn't to say it is a simple methodology to undertake. For this approach to work, the contractor is under far more pressure in what is an already fraught market. Buttery explains that to undertake a design and build contract means serious responsibility, and it must be in a position where it can manage it. "It is much more onerous for the contractor to deliver as there is far more for us to do."
Buttery also believes that such an approach makes better employees, citing those project managers who consequently get involved in design often turn out to be the best design managers, as they bring knowledge of the building process and can apply that. Furthermore, it isn't only the client who benefits from tighter project control and a cost-effective approach. From a contractors' point of view, it simplifies the construction process, eliminating erroneous procedures. According to Kez Taylor, managing director, ALEC, it affords the company greater control. "We find purely as a contractor, generally where you get tripped up is when you don't receive the information in the right sequence in order to execute the work efficiently.
"In design and build, the design component falls under our responsibility, so we will appoint the consultants and from a client's perspective, you have a one-stop shop. What happens in traditional contracts is that you have a lot of conflict with the design team and execution team. So you end up with conflict because the contractor has huge penalties and has to pull the job off, and the design team that is continually changing the design and not giving you the information in the right kind of sequence and time you require."
Taylor isn't surprised at the reticence shown so far by clients in the region, indicating it will take a while for clients to change to another model. In other parts of the world, namely Australia, it is a very common approach to construction. So far, just 20% of its projects are through design and build including the Between the Bridges contract - a $272 million project in Abu Dhabi being one of them. Taylor is confident that, once the message gets heard, more will follow this form.
Cyril Williams, commercial manager, Al Rostamani Pegel, highlights the change in mindset among clients, explaining also that it presents another avenue for companies to expand their business. "We have done about four towers now (design and build), and it's another way to grow our business. We go to a client who has a piece of land and say: ‘let us do everything for you'. They say, ‘well that's great, but how do you know what we want?' And we tell them, we will make them part of the team. It's gaining ground."
Like Taylor, Williams believes a shift in conventional thinking needs to happen before design and build is embraced fully. "I think we have got to get past the stage where everyone is wary of everyone else; I think it's a construction thing. I don't think we will get away from it completely, but I think partnerships will be better in the future."
While there has been a distinct shift away from the ‘us and them' form of contracting that prevailed in the years gone by, there is a growing understanding from contractors that, with the proliferation of projects on offer, theirs is a strong position. It is arguably the ability to be more selective in the future, as much as changing attitudes that could drive change in the future.
Despite being an established form of procurement in the US and UK, design and build is slowly becoming more popular in the UAE. Construction Week summarises some other contracts used in the region:
Lump sum/Fixed price contract - One of the most popular forms of contract, this sees the work carried out at a specified price. With massive fluctuations in materials prices, this has come into question, as contractors are at a disadvantage and stand to lose sizeable sums over the course of a project.
Remeasured contract - This contract is based on remeasurement whereby the consultant estimates the quantities required for the construction and the contractor commits to the unit price, which defines the initial tender price and quantities of materials used by the contractor. This may change, depending on the quantities of materials used.
BOT - The build-operate-transfer (BOT) model is an integrated partnership that combines the design and construction responsibilities of design-build procurements with operations and maintenance. It is commonly used for plant projects.
Cost-plus contracts- A move away from fixed-price contracts, this takes into account price fluctuations and other added project costs. This is recognised as a far more collaborative approach to construction.
NEC3 - A form of contract that says the developer and contractor share the risk. Believed to be an improvement over more traditional forms of construction contracts due to its flexibility, clarity and simplicity. Its focus is designed to improve the partnership between the project manager and the contractor, and encourage them to resolve matters, which may hinder progress or increase costs, as they arise.
Design and build - One entity performs both the design and construction under a single contract. Often the design and build contract is awarded by some process other than competitive bidding thus, design and build differs from traditional contracts in two ways. First, the design and construction components are packaged into a single contract and second, the single contract is not necessarily awarded to the lowest bidder after competitive bidding.
