Drawings and calculations are the two types of documents that make up structural design documentation. Both are subjected to intense scrutiny during the process of obtaining all necessary permits, and they are both critical in ensuring the structure’s stability and ability to carry the design load. Engineers can use calculations to determine the strength, stiffness, size, and layout of members and connections, or the structural elements that are best for a particular project. But when the construction commences, drawings become critical. Hiring a Diagram and estimating service is an essential step towards getting the perfect estimate.
Engineers use drawings to communicate the design requirements of a project to contractors. They display the various types of members and connections, as well as their locations and interactions. The clarity and level of detail in structural drawings have a direct impact on a contractor’s ability to read and understand what they should be building. Quality building and unit diagrams shorten permit approval cycles, aid contractors in estimating accurately, and reduce the risk of RFIs and change orders during construction.
Importance of Quality Structural Drawings:
Unless your project is minor or cosmetic, you will need to obtain several permits before beginning work. Permits for mechanical, electrical, plumbing, and demolition work, as well as a permit for the entire project, may be required.
Although some permits can be obtained online or over the counter with only a few supporting documents, the majority of permit applications are subject to the Building Department’s plan check review. Submitting clear, accurate, and compliant drawings and calculations with your permit application can help you save time and money by reducing the number of revision cycles.
Your prospective contractors will provide you with work estimates before the start of construction. These will be based on the bid set of drawings that your design team sends out for bidding. Although these drawings are not intended for construction, they should effectively communicate the project’s design requirements. Your contractor may miss parts of the scope or overprice your bid due to ambiguity and a lack of detail. When the project’s true construction costs don’t match your budget, such inaccuracies can become a major headache. Quality drawings with the right level of detail can help your contractors give you more accurate quotes.
Avoid Extra Costs During Construction
Structural drawings guide the contractor through the selection and installation of members and connections once construction begins. Contractors may request clarification via an RFI if the drawings aren’t precise or clear, or they may misinterpret the drawings entirely.
RFIs are a way for the contractor and the design team to communicate formally. It protects against errors, but it also consumes time and resources. When reviewing their drawings for accuracy and clarity, every design team should aim to avoid time-consuming RFIs during construction. If a contractor is misled by vague or inaccurate drawings during construction, the cost and schedule consequences can be severe.
