Design Development (DD) and Construction Documentation (CD)

Design Development (DD) and Construction Documentation (CD) Estimates are critical aspects of any construction project. DD estimates refer to the cost estimates that are prepared during the design phase of a project, while CD estimates are prepared during the construction documentation phase of a project. 

DD estimates are developed during the preliminary design phase of a project and help to establish a budget for the project. These estimates are typically based on conceptual drawings and are used to determine the scope and feasibility of a project. They help to identify potential design challenges and provide an early indication of the cost of the project. 

CD estimates, on the other hand, are developed during the construction documentation phase of a project. These estimates are based on detailed construction drawings and specifications and provide a more accurate cost estimate for the project. CD estimates take into account the cost of labor, materials, and equipment required for the project. 

It is important to note that DD and CD estimates are not set in stone and can change throughout the course of the project. As the design develops and construction documentation progresses, new information may come to light that can impact the cost of the project. It is important to update estimates regularly to ensure that they remain accurate. 

When developing DD and CD estimates, it is important to work closely with the design team and construction professionals to ensure that all aspects of the project are considered. This includes considering the cost of any necessary permits, inspections, and fees, as well as any unexpected costs that may arise during construction. 

In conclusion, DD and CD estimates are critical components of any construction project. They help to establish a budget for the project and provide valuable information on the feasibility and cost of the project. It is important to work closely with the design team and construction professionals to ensure that estimates are accurate and up-to-date throughout the course of the project.
