When working with a building contractor, it is possible that you will come across an agreement known as the design and build contract. Traditionally, a person would be able to design and develop building plans independently with consultation assistance from qualified architects. However, there are now qualified design architects that will provide full design and construction services. To ensure you are not ‘duped’ by construction professionals, it is important to understand what a design and build contract is and how to can benefit your construction process. This article will provide information on the different advantages and disadvantages of these types of contracts.
What Are The Different design and build Advantages?
Design and build (D&B) contracts are typically used as a procurement route for developers as it allows a certain amount of control over the costs of construction. In general, the lump sum contracts would result in a building contractor agreeing to take the responsibility for both design and construction. The benefit is that the building contractor will be fully responsibility for all aspects of the construction despite agreeing on the initial design with the developer.
If the agreed-upon design is not amended throughout the design and build London project, the developer can provide a reasonably accurate quote of the price for construction. Of course, it is possible that the developer will make certain changes. Minor changes may not be possible to modify after construction commences; however, any changes that are implemented will make it easier for the contractor to offer a more accurate quote for construction.
A further advantage to using a D&B contract is the reduced construction time. When a contractor takes full responsibility for both the design and construction aspects of the project, both of the elements will be completed concurrently. This means that only one person will need to be consulted for any challenges that may be experienced and all alterations do not require any additional verification.
What Are The Disadvantages Of The Design and Build London?
Not all individuals in the construction industry are fans of D&B contracts; therefore, it is worth discussing the different drawbacks of this type of agreement. One of the drawbacks to a D&B contract is the freedom provided to the builder or contractor when they take responsibility for all building and design duties. If a contractor is given a free hand to develop the building based on a pre-agreed price, there is a great chance that they will work according to the lowest possible specifications to save costs.
Another drawback to the D&B contract is the problem that the contractors used are builders and not architects or developers. An architect or developer will have several years of training and experience; therefore, they have various specific skills relevant to the designing and building of a legally regulated structure. The builder may not have the correct abilities, training or knowledge to provide a similar or effective service. By providing the contractor will all responsibilities, there is a chance the structure will be poorly built and will not adhere to building regulations.
