Rebar Detailing Services
Precision Rebar Detailing That Turns Concrete Into Structure
At Gsource Technologies, our team of experienced rebar detailers and structural engineers backed by 16+ years of AEC project delivery and ISO-certified workflows ensures reinforcement bars are placed precisely where structural design demands them across foundations, columns, beams, slabs, and walls. These details integrate seamlessly into BIM solutions, shop drawings, prefab details, precast detailing, reinforced concrete detailing & more.
We assist with the full range of detailing requirements, bar sizes and grades, locations and spacing, bend details, lap splices, development lengths, concrete cover requirements, stirrups, and ties - producing 2D AutoCAD placement drawings and 3D models in Tekla Structures and Revit. Every deliverable is reviewed against ACI 318, ASTM A615/A706, and CRSI standards by our QA team before delivery. We use RebarCAD, AutoCAD, Revit, RGS Rebar, Tekla Structures, and MultiSUITE to produce fabrication-ready drawings your fabricators can act on and your engineer of record can approve without revision cycles.

Our Core Services
Bar Sizes and Grades
We specify bar diameters from #3 to #18 and grades per ACI 318, ASTM A615, A706, and CRSI requirements, aligned with your structural engineer's design intent.
Bar Locations and Spacing
Placement drawings include clear cover dimensions, development lengths, and lap splice zones, giving field crews unambiguous installation instructions.
Bend Details
Each bend schedule includes shape codes, bend angles, hook dimensions, and radii per CRSI and ASTM standards, ready for direct input to fabrication equipment.
Stirrups and Ties
We detail closed and open stirrups, seismic hoops, and spiral ties for columns, beams, and shear walls, including spacing transitions near support zones.
Rebar Drawings and Scheduling
Bar bending schedules list bar mark, shape code, diameter, cutting length, and quantity formatted for direct fabricator use with no manual interpretation required.
2D and 3D Modeling
3D models in Tekla Structures or Revit allow multi-trade clash detection before drawings are issued catching conflicts with MEP, structural steel, and precast elements early.
As-built Drawings
Produced post-installation to reflect final field conditions, as-built rebar documentation is essential for structural renovations, retrofits, and regulatory sign-offs.
Roof Truss and Joint Details
Connection and joint details cover bearing zones, embedment plates, and reinforcement continuity at transfer levels, high-seismic joints, and precast interfaces.
Total Rebar Estimation
Full quantity take-offs covering bar weight by element type, accessories, and erection inputs formatted for estimating teams and procurement workflows.
Grade Beam Detailing
Grade beam drawings include top and bottom mat reinforcement, stirrup spacing, tie conditions, corner details, and construction joint locations.
Foundation Details
Foundation rebar detailing covers spread footings, pile caps, raft slabs, and mat foundations, with dowel schedules and column base plate interface details.
Rebar Shop Drawings
Delivered in DWG, PDF, or IFC format shop drawings include bar marks, bending shapes, placement notes, and tie wire details, reviewed against ACI 318, ASTM, and CRSI before issue.
