Structure Rebar Detailing Services — LOD 400 Shop Drawings
We deliver precise concrete reinforcement placement drawings, detailed bar bending schedules (BBS), and clash detection analysis conforming to CRSI and ACI 318 standards.
What are concrete rebar detailing services?
Concrete rebar detailing services translate structural design plans into precise fabrication schedules and installation plans for steel reinforcement cages. These drawings specify the exact cut length, bending shapes, lap splice configurations, and clear cover spacing requirements needed for fabricators to bend and placers to install rebar.
By modeling the concrete reinforcement cages in 3D, we identify congested regions—such as beam-column nodes—where rebar spacing conflicts may make pouring concrete impossible. This proactive clash resolution reduces RFI delay times and concrete void defects.
REBAR DETAILING DELIVERABLES
Rebar Placement Drawings

REBAR DETAILING FAQS
What is LOD 400 rebar detailing?
LOD 400 (Level of Development 400) rebar detailing models reinforcement steel in full 3D, including exact bar lengths, hook angles, bend diameters, lap locations, support chairs, and tie bars. This ensures the model represents a fabrication-ready configuration.
Which standards do your rebar drawings conform to?
All detailing and scheduling conform to the American Concrete Institute (ACI 318) Building Code Requirements, Concrete Reinforcing Steel Institute (CRSI) Manual of Standard Practice, and relevant ASTM standards.
How do you handle rebar clash detection?
We model the concrete formwork and reinforcement in 3D. This allows us to run automatic clash checks to find conflicts between rebar cages, anchor bolts, post-tensioning anchors, and MEP penetrations, resolving them before shop fabrication.
What is a Bar Bending Schedule (BBS)?
A Bar Bending Schedule is a tabular listing of all reinforcement bars showing bar mark, size, weight, cut length, bending shapes (using standard code diagrams), and quantities. It acts as the cut list for rebar fabrication machines.
What is your standard turnaround time for concrete rebar drawings?
We provide initial estimates and foundation drawings within 3 to 5 business days of receiving the final structural drawings. Complete packages take 7 to 14 business days, depending on project complexity.
Do you detail rebar for precast concrete components?
Yes. We provide integrated precast rebar detailing, coordinating reinforcement placement, lifting embeds, and connection plates for double-tees, wall panels, and columns.
