and is able to call upon subcontractors' construction expertise throughout. The architect bears the greatest risk but also has more control over the project than in either the traditional approach, or in the contractor-led and other architect-led design–build projects. Contracts A single set of integrated contracts combining design and construction responsibilities, rather than two discrete contracts for each, acknowledges the interdependence of the architects' and construction trades' project responsibilities, and reduces the likelihood of disputes. Design–build institutes In 1993, the Design-Build Institute of America (DBIA) was formed. Its membership is composed of design and construction industry professionals as well as project owners. DBIA promotes the value of design–build project delivery and teaches the effective integration of design and construction services to ensure success for owners and design and construction practitioners. The Design-Build Institute of America is an organization that defines, teaches and promotes best practices in design–build. The Canadian Design-Build Institute (CDBI) describes itself as "The recognized voice of Design-Build practitioners in Canada, promoting and enhancing the proper utilization of Design-Build method of procurement and contracting". Advocacy Not all design–build projects are alike. Here, there is a distinction between design–build projects led by contractors and those led by architects. Architect-led Design Build is a form of 'design–build' that, according to the DBIA, has been rapidly gaining market share in the United States over the past 15 years. The Design Build Institute of America describes the design–build process as follows: Taking singular responsibility, the design–build team is accountable for cost, schedule and performance, under a single contract and with reduced administrative paperwork, clients can focus on the project rather than managing disparate contracts. And, by closing warranty gaps, building owners also virtually eliminate litigation claims. The DBIA's 2005 chart shows the uptake of design–build methods in non-residential design and construction in the United States. Architect-led design–build is sometimes known by the more generic name "designer-led design–build". Although employed primarily by architects, architectural technologists and other architectural professions, the design–build structure works similarly for interior design projects led by an interior designer who is not an architect, and also for engineering projects where the design–build team is led by a professional structural, civil, mechanical or other engineers. In addition, it is common for the design professional who leads the design–build team to create a separate corporation or similar business entity through which the professional performs the construction and other related non-professional services.
