What Does DD, CD & SD Stand for in Construction?
Construction is the culmination of a lot of technicalities and we are here to simplify them for you.

Construction is a culmination of a lot of different fields of discipline coming together to create the infrastructure to meet the consumer demand. Construction is a lengthy process, one which leaves no margins for error as the even the smallest of miscalculations may lead to loss of life and property. Construction jobs require a lot of effort from everyone involved and different components need to co-operate for the completion of the job. Building a project is a multileveled job with the actual construction being the last stage. Before a building can be constructed, it has to go through cycles of amendments and changes to fit the budget and the vision of the client and the architect to reach a schematic that satisfies all the parties.
Design development (DD), construction document (CD), and schematic design (SD) are stages that involve a majority of planning needed to complete the job and cover almost all and important aspects of the project. These phases represent different rates of completion of the pre-project documentation and lay a foundation for the construction work to be started.
DD, CD and SD are all design stages that cover the whole process of the evolution of the construction design. These stages define the stages of construction and development of the project and are a way to keep a track of work progress.
Schematic Start – The Way to Begin
The preparation of the project starts with a schematic design with the architects developing design drawings creating conceptual construction drawings and research about the permissions and jurisdictions. The design would change a number of times during this phase to meet the project requirements. Schematic design is the phase where the outline of the project is created including the mechanics the owner may want to install. The scale of the components along with their relationship with each other, detailed sections, floor plans, elevations and schedules are decided with the consent of the owner. These schematics are used to get approval for zoning and applying for granting of various permits.
By the end of schematic design, you’d have a schematic plan of the construction and a base to build your further design from. Get in touch with our experts to know more about Design DocumentsE-mail: firstname.lastname@example.org

During design development, the detailed design is created and this design is used to float tenders and the projects will be quoted by contractors through this design. Structural systems are planned and the building materials agreed on and compliance with the local building codes is checked. Detailed design sets take shape and influence the schematics prepared during SD. The schematics are redesigned according to the accepted dd sets.
During Design Documentation, the architect further designs the landscape, electric, mechanical, and architectural components and submits them for the owner’s approval and possible review. Design development plays a huge role in determining the possible expenditures and overall cost of the project. This requires the architects to actively co-operate with other involved parties to determine the cost of the project and make changes to fit the allocated budget.
By the end of design development, you have developed building sections and fully dimensioned floor plans.
Construction documentation begins after the owner and architect are both satisfied with the plans and agree on the cd sets. No further design changes are incorporated and the focus is on producing construction document sets that describe the details of the design required for constructing the project. These construction drawings are the final blueprints that are used as guides for building the project. These construction documents contain all the details ranging from structural to mechanical systems to be installed along with the materials, their quantity and quality to be used.
A construction documentation checklist is used to keep track of the parts that have been completed and the materials that have been used or are being used in the construction. This helps keep track of the consumption of the material, the speed and completion rate and allows the architects and builders to estimate the time of completion of the project. Many construction companies provide construction document services to allow for a faster method for the construction company to complete their work as they don’t have to constantly check with the architects regarding the construction document sets and can just continuously update their own construction documentation checklist.
It is during CD that you decide upon and complete the furnishings, fixtures and equipment that will be installed into the building and is more often than not provided by the client. The construction company is supposed to install whatever the client wants to be there.
All these elements and phases come together for the completion of a project and are essential in bringing the idea of the owner to reality. As always, BluEntCAD’s experts are here to help you out.
