FAQ
Tejjy’s shop drawings for contractors follow a streamlined workflow that ensures every drawing is constructible and fabrication-ready.
Our 5-Step Shop Drawing Workflow:
- Step 1: Input review & standard verification
- Step 2: BIM modeling & clash coordination
- Step 3: Dimensioning & fabrication detailing
- Step 4: QA/QC validation & revision tracking
- Step 5: Final submittal & client approval
The main difference between shop drawings and as-built drawings lies in their purpose and timing.Shop drawings illustrate how design elements will be fabricated, assembled, and installed before construction begins.In contrast, as-built drawings document the final built conditions after completion, capturing every on-site modification or deviation.Together, these drawings provide complete project documentation essential for facility management and future renovations.
In any construction project, multiple drawings used in building design work together to guide every phase, from concept to completion. Architectural drawings set the design intent, structural drawings define load-bearing systems, and MEP drawings coordinate mechanical and electrical layouts. Shop drawings ensure precise fabrication, while as-built drawings record the final built outcome. Understanding when to use each drawing type ensures smoother coordination and better project outcomes.
The major advantages of shop drawings in construction include improved design clarity, clash-free coordination, and higher fabrication accuracy.
They enable contractors to identify errors early, reduce rework, and maintain project timelines. By delivering detailed visual and dimensional information, shop drawings also enhance collaboration among architects, engineers, and fabricators, ensuring constructible and compliant project delivery.
Integrating prefabrication with BIM shop drawings enhances construction efficiency by connecting digital design precision with real-world fabrication.
BIM-based shop drawings provide coordinated, clash-free models that help prefabrication teams manufacture components exactly as intended.
This integration ensures dimensional accuracy, seamless trade coordination, and reduced on-site rework.
It also enables early detection of design conflicts, shortens construction schedules, and supports sustainable practices through material optimization and reduced waste.
