Service 04
Concrete structural details, foundation and equipment-base drawings, reinforcing-bar placing details and bar bending schedules (BBS), based on approved concrete design and project detailing requirements.
We prepare reinforced concrete (RCC) and rebar detailing documentation from approved structural design information for energy and industrial project packages.
Work can include foundation and equipment-base details, beams, columns, slabs and pedestals, reinforcement layouts and placing drawings, embedded-item interfaces and bar bending schedules.
The drawing set communicates the approved concrete geometry and reinforcement requirements clearly to construction and reinforcement supply teams. Bar marks, schedules, sections and revisions are coordinated to the project's detailing rules, drawing conventions and reinforcement standards. The structural designer keeps responsibility for reinforcement design, structural adequacy and engineering approval unless the contract defines otherwise.
Reinforced concrete and rebar detailing turns the engineer's approved concrete design into drawings that show where every bar goes and schedules that tell the supplier what to cut and bend. A package typically includes concrete arrangement and detail drawings for foundations, equipment bases, pedestals, beams, columns and slabs, rebar placing plans, elevations and sections, embedded-item and anchor interface details, and bar bending schedules listing each bar mark with its shape, dimensions and quantity. Inputs are the approved concrete drawings or reinforcement design, the rebar specification with cover, lap and anchorage requirements, the owner's or EPC's detailing standards, the required BBS format and scheduling convention, and vendor anchor and embedment drawings. Bar marks, schedules and sections are revised together so that drawings and BBS always match. Reinforcement design, foundation design and structural adequacy stay with the responsible designer, whose design information remains distinct from the placing documents.
Downstream of approved concrete and reinforcement design. The designer specifies bar sizes, spacing, cover, laps and anchorage; we detail and schedule them so they can be fixed on site and supplied.
Concrete arrangement drawings without reinforcement sit under Civil & Structural Engineering Drafting. Where the steel a foundation supports is also being detailed, pedestals and embedded items are coordinated so both packages describe the same interface.
Discuss Your ScopeThe work that can be commissioned under this service. Any item can be scoped on its own or as part of a package; deliverables are agreed in writing for each project.
The work within this service, in the order it is usually produced. Any part can be scoped on its own; the deliverables for each package are agreed in writing.
Approved concrete dimensions, structural notes, reference grids, reinforcement design information and vendor, anchor and embedment data checked before detailing.
Concrete foundation outlines, sections, plinths, pedestals and equipment-base details prepared from approved design requirements.
Approved concrete beams, columns, slabs, walls, pits and other structural concrete elements within the agreed scope.
Bar arrangements, spacing, reinforcement sections, bends, laps, anchorage and bar references detailed consistently with the designer's instructions.
Specified anchor bolt settings, embedded plates, sleeves and structural interface references coordinated. Anchor design is not implied.
Site-usable reinforcement placing plans, sections, schedules, bar marks and placement notes.
Shape, size, length and quantity lists prepared to the contractual scheduling convention and the applicable bending standard.
Schedules and quantities updated after approved changes, with linked drawings and mark-ups cross-checked.
Structures this service regularly covers on energy and industrial projects. These are applications, not stages of the work.
What we work from
Each input is logged with its revision and status before production starts.
What you receive
Actual deliverables, formats and assumptions are negotiated and confirmed in the scope of work for each package.
Reinforcement is detailed and scheduled to the concrete and bar-scheduling standards specified for the project, for example ACI or BS practice.
The scope of work records the applicable standards and editions for each package. A reference to a standard does not imply design verification or certification.
How standards are appliedBar sizes, spacing, cover, laps and anchorage are taken from the designer's approved information; detailing does not set them.
Shape codes, bending dimensions and schedule format follow the convention the project specifies, for example BS 8666 or ACI practice.
Drawing presentation, bar marking, notes and numbering follow the project's detailing rules.
Anchor bolts, embedded plates and sleeves follow the issued vendor and steel drawings; drawings and BBS are revised together.
Examples a project may specify
Illustrative only, not a fixed or exhaustive list. The governing documents and editions are those named in your contract and project specification.
RCC drawings and schedules are produced to the project's CAD standards; the platform and version are confirmed during scope review.
Software listed reflects the senior team's project experience. Supported platforms, versions and file formats for a new package are confirmed during scope review.
File formats & workflow2D Drawing Production
Arrangement, detail, RCC and as-built drawings, and revision incorporation on existing drawing sets.
The usual sequence for this service. Steps can overlap, and review comments loop back to earlier steps.
Approved concrete and reinforcement information confirmed.
Foundations, bases and members drawn with their sections.
Bars detailed and embedded items coordinated from the design.
Site-usable placing plans, sections and bar marks produced.
Schedules and quantities prepared from the placing drawings.
Drawings and BBS checked against each other and the design.
Submitted for review; drawings and schedules revised together.
Review & responsibility
Drawings and bar bending schedules are checked against each other, bar mark by bar mark, and against the approved reinforcement design before issue. Review comments are incorporated and the drawings, BBS and quantities are revised together. Producing a BBS does not constitute structural design approval.
This is detailing and documentation derived from the qualified designer's approved inputs. Reinforcement design, foundation design and concrete structural adequacy remain with the responsible designer, and the designer's reinforcement information stays distinct from the placing and fabrication documents we produce.
Arrangement drawings without reinforcement sit under Civil & Structural Engineering Drafting; separately purchased quantity reconciliation under Material Take-Offs, BOM & Engineering Documentation. Work outside these limits can be discussed as a custom scope.
Excerpts from drawings produced by our senior team during previous professional engagements. They are confidential, so they are reduced, watermarked and shown without title blocks. Full drawings are for clients only.
Senior team experience
Senior team experience on this NGL recovery project included RCC structures and pipe rack layouts, with general arrangement drawings, isometric drawings and bar bending schedules.
Straight answers on how this service works. Scopes outside what is described here are reviewed case by case; we confirm we have the right competence before quoting.
Ask about your scopeNot by default. It is detailing and documentation derived from the qualified designer's approved inputs.
A separately defined BBS package can be assessed, based on suitable approved drawings and the scheduling rules for the project.
The applicable project requirements and the BBS and detailing conventions are evaluated against your specification during the RFQ, for example BS 8666 or ACI practice.
Where the drawings support it, pedestals, bases and embedded items are coordinated with the supported steelwork so both packages describe the same interface.
