Why Quality Structural Drawings Are Important For Your Project

Drawings and calculations are the two basic categories into which structural design papers may be divided. Both are examined throughout the permitting process and are equally crucial in ensuring that a structure can support its intended loads. However, as the building begins, drawings become even more important.

Engineers use calculations to choose the optimal structural connections and components for a particular project. Engineers can calculate the strength, stiffness, size, and arrangement of these parts.

Engineers communicate a project’s design needs to contractors through drawings. They display the different member and connection kinds, their geographical locations, and their interactions. A contractor’s ability to read and comprehend the structure they should be creating directly depends on the clarity and degree of detail of the structural drawings.

 Quality drawings shorten the number of times a permit must be revised, assist contractors in estimating costs accurately, and limit the possibility of information requests (RFIs) and modification orders during construction.

Quicker Granting

You may need to get any licenses before construction can start unless your project is quite small or just aesthetic. These may include a permit for the entire project as well as one for mechanical, electrical, plumbing, and demolition work. A plan check evaluation by the Building Department USA is required for the majority of permit applications, even if certain permits may be acquired online or in person without any supporting documentation. 

Building inspectors evaluate your project’s adherence to regional codes throughout this procedure, and calculations and drawings for the structural design are assessed. The reviewers may make adjustments that your design team must carry out before resubmitting the papers if they discover flaws or have trouble understanding the designs. 

Your project may be delayed for months as a result of this cycle, which continues until the authorities are happy with compliance. Reduce the number of revision cycles and accelerate the start of your project by including accurate, precise, and compliant drawings and calculations with your permit application.

Exact Quotation

Your potential contractors will provide you with their cost estimates prior to the commencement of construction. These will be based on the bid set of drawings that your design team releases for bidding. Despite not being intended for construction, these drawings should effectively explain the project’s design needs. 

Lack of clarity and vagueness might cause your contractor to miss some of the scopes or overcharge you. When the exact building expenses of the project don’t fit inside your budget, such errors might cause severe problems. A suitable amount of detail in your designs will help your contractors price you more accurately.

Avoid Additional Costs While Building

Structural drawings help the contractor choose and install members and connections once work is underway. Designs that are vague or confusing may cause the contractor to issue an RFI for clarification or to misread the drawings entirely.

RFIs serve as a formal route of communication between the design team and the contractor. While it protects against mistakes, it also consumes valuable time and resources. Every design team should strive to avoid time-consuming RFIs during construction by checking their drawings for correctness and clarity.

The contractor may be misled by ambiguous or erroneous designs, which might have a serious impact on budget and time. Change Orders that result from these adjustments to the contract’s scope, schedule, and budget may result in additional expenses and risk the project’s completion date.

RFIs and Change Orders may be necessary for a variety of reasons, but your design team may help avoid them by providing thorough, coordinated drawings that your contractor can comprehend.
