What is the Difference Between Project Feasibility Evaluations and Stamped Wall Drawings?

Redi-Rock’s in-house engineering team has helped architects, engineers, wall designers, and installers realize thousands of retaining wall projects worldwide. Our engineers answer product questions, provide design and analysis guidance, and perform plan and calculation reviews. Our team is sometimes asked to provide stamped wall drawings. Two of our team's most frequent support requests involve project feasibility evaluations and stamped wall drawings.

What Does Redi-Rock Consider a Project Feasibility Evaluation?

Our engineering team is frequently called on to help determine whether a project is viable. We consider a project feasibility evaluation an early-stage analysis that assesses whether using Redi-Rock is practical from a technical standpoint. We examine and can recommend the use of wall types (gravity, MSE/reinforced, or hybrid) and specific blocks. We do not replace the expertise of your local engineer. Location-based factors like geological setting, environmental impact, and regulatory compliance are best left to professionals who understand their service areas more deeply. Our feasibility evaluations are performed before detailed engineering design begins and do not contain final construction details. They are intended to help architects, engineers, and wall designers determine if a project can proceed with a Redi-Rock solution.

What is a Stamped Wall Drawing

A stamped wall drawing is a final, approved engineering drawing that has been reviewed and officially sealed by a licensed professional engineer (PE). The stamp signifies that the design meets all applicable codes, regulations, and industry standards. These drawings are legally required for permitting and construction. They include detailed specifications, dimensions, materials, and construction methods.

Redi-Rock’s technical support team includes professional engineers, but we cannot offer stamped wall drawings.

What are the Key Differences Between Feasibility Evaluations and Stamped Wall Drawings?

The primary differences between project feasibility evaluations and stamped wall drawings can be divided into four categories as follows:

• Purpose. A feasibility evaluation assesses project viability, while a stamped wall drawing provides approved drawings to guide the wall construction.

• Stage in Process. A feasibility evaluation occurs in early-stage planning. A stamped wall drawing is the final design step before construction commences.

• Content. A feasibility evaluation involves examining multiple wall types (gravity, MSE/reinforced, or hybrid), products, and the area subsequently required to install the wall. A stamped wall drawing features detailed engineering drawings with specifications and details for a specific wall type.

• Legal Requirement. Feasibility evaluations are conducted by engineers but are not stamped and are not required. Stamped wall drawings are legally required for permitting and construction and must be stamped by a licensed PE.

Understanding the distinction between feasibility evaluations and stamped wall drawings is crucial for successfully planning and executing a retaining wall project. While feasibility evaluations help determine whether a Redi-Rock solution is viable early in the process, stamped drawings provide the information needed for permitting and construction.
