Save Time and Money with Bautex Blocks in Design-Build Construction

Design-build is a method of con­struc­tion in which under a single contract a design-build team works alongside the project owner to provide design and con­struc­tion services. A con­trac­tor, designer, developer, design-build firm, or a joint venture can lead a design-build project, but there is only one contract for both designing and building. Design-build delivery is an alter­na­tive to tra­di­tion­al design-bid-build delivery that splits the design and con­struc­tion services into separate contracts. The advan­tages of design-build for the owner are there is only one contract to manage and one single point of respon­si­bil­i­ty because the designer and con­trac­tor are on the same team. With design-bid-build, owners must manage two separate contracts. In these cases, the owner often becomes the middleman between the designer and con­trac­tor. The advan­tages of design-build to the con­trac­tor is it increases a con­trac­tor’s inde­pen­dence, pro­duc­tiv­i­ty and profits. Design-build is a single-contract delivery method of con­struc­tion that can deliver suc­cess­ful, superior results in less time and for less money that design-bid-build delivery.

The design-build method of one contract between the owner and the design-build team fosters col­lab­o­ra­tion and teamwork between the designers and builders.The design-build method can also result in quicker com­ple­tion of projects with fewer change orders than the design-bid-build method; which saves money. In fact, a study by the Computer Inte­grat­ed Con­struc­tion Research Program of Penn State evaluated the financial benefits of the design-build method of construction.

  • Design-build unit costs were 6 percent less than design-bid-build. Unit cost is the gross square footage divided by the final project cost
  • Design-build con­struc­tion speed was 12 percent faster than design-bid-build. Con­struc­tion speed is the square footage of con­struc­tion work put in place per month
  • Design-build delivery speed was 33 percent faster than design-bid-build. Delivery speed is similar to con­struc­tion speed but includes con­struc­tion and design times

The Five Phases of the Design-Build Process

Select a design-build firm or con­trac­tor. Typically, building owners select a design-build con­trac­tor based on estimated price and added value in addition to expe­ri­ence, expertise, and credentials.

The pre-con­struc­tion phase is when the design-building team assesses the owner’s goals, vision, finances, and current and future building needs. During the pre-con­struc­tion phase, the team also begins archi­tec­tur­al, mechan­i­cal and elec­tri­cal system assess­ments and eval­u­a­tions of con­cep­tu­al floor plans, fire and smoke code com­pli­ance, interior room finishes and struc­tur­al systems. Also, at this time, surveyors perform a field assess­ment of the job site to prepare it for con­struc­tion. All this infor­ma­tion is essential to the team to identify the right facility, design and con­struc­tion program that will achieve the goals within the agreed upon budget and schedule.

The archi­tec­tur­al design phase is when the con­struc­tion team and project managers partner with a design team to value engineer cost savings into the design. The purpose of value engi­neer­ing is to improve the function and reduce the cost of the building. Value engi­neer­ing evaluates a building’s projected lifetime use and deter­mines the best com­po­nents to use that will increase the value of the structure over its expected lifespan. Max­i­miz­ing the project’s function while min­i­miz­ing cost generates the greatest value for design-build clients.

With a design-build project, the con­struc­tion phase quickly follows the archi­tec­tur­al design because there is no need to bid out a con­struc­tion contract.

After com­ple­tion of the project, the post-con­struc­tion phase includes walk-throughs, instruc­tion­al videos, hands-on training and core doc­u­men­ta­tion for owners, managers, and man­age­ment teams.

Utilizing Bautex Wall System for Design-Build Solutions

The Bautex Wall System is a design build exterior wall solution that produces value engi­neer­ing cost savings through improved function and reduced costs. The Bautex™ Wall System is built with insulated concrete blocks that simplify con­struc­tion by combining structure, enclosure, con­tin­u­ous insu­la­tion, and air and moisture pro­tec­tion in a single inte­grat­ed assembly. A designer, con­trac­tor, developer or design-build firm can manage the designing and building of Bautex Blocks walls under one contract. Then, a sub-con­trac­tor or self-per­form­ing general con­trac­tor, once trained by Bautex, can easily install the Bautex Blocks. Utilizing Bautex Blocks in a design-build process can save time and increase the value and function of a structure. 

Design-build involves a design-build team that work under one contract with a project owner. One team, one contract, and one owner unify the flow of work through­out the lifespan of the project. The design-build method also saves time, money and ulti­mate­ly improves the value of the project. In fact, design-build is becoming one of most sig­nif­i­cant trends in design and con­struc­tion today. According to the Design-Build Institute of America, the use of design-build con­trac­tors or firms has sig­nif­i­cant­ly increased in the United States over the past 15 years. Also, a recent report indicates that the gov­ern­ment offers about 50 percent of its contracts and the army and navy offer more than 75 percent of their contracts as design/​build work.
