Rebar Estimation
Social Share
The teams at Rebar D&D have a wealth of experience in the reinforced concrete construction industry having completed close to 3000 rebar estimation and detailing projects.
Rebar Estimation
This is the process of quantifying the reinforcement in a concrete structure, where we categorise the steel by type, bar size and bend category; element wise and segment wise. We also provide mesh and accessories details, as well as concrete quantities needed for a job; when it is included in the scope.
At Rebar D&D, our adept estimators are equipped with advanced tools and software like ASA, RebarCAD/CADSRC, Bluebeam and On-Screen Takeoff (OST) to produce accurate and comprehensive rebar estimates in various formats. The client is now armed with complete knowledge to be a confident competitor in the bidding process, to win the job

Rebar Detailing
Here we prepare reinforcement placing/shop drawings derived from the design drawings which are then used by the contractor to place the bars at the project site. These shop drawings enable us to generate detailed instructions on the number, size, shape and location of the rebar to be placed in the form work, prior to concreting. The software also helps us produce Bar Bending Schedules in varied customised formats, which are then input into automated machines in fabrication shops.
At Rebar D&D, we use ASA aor RebarCAD/CADSRC to produce shop drawings as per the structural codes and construction practices of the region. We adhere to a three tier system to whet the quality and flow of information in both directions before the final drawings are delivered to the client.

Project Management
There are three stages in this process.
The project managers at Rebar D&D work with the execution team to lay the ground work accordingly. This includes incorporating other aspects of construction such as MEP, highline, rocks on ground,drainage lines etc.that could be taken from the contract/civil drawings.
Team Rebar D&D understands the importance of scheduling the Shop Drawings for approval from the engineers and more significantly, scheduling the Field Use drawings along with the Bar List for Fabrication. Our project managers ensure stringently that adequate lead time is maintained for approvals as well as the duration needed for fabrication and material delivery logistics.
When a client makes a specific request, the team at Rebar D&D coordinates directly with the contractor – it is this instant connect and holistic method that has proven to be a superior time saving support to our clients. Our in-depth detail in constructability combined with an inclusive approach reflects in the fact that even after submitting very precise drawings; we will adequately support the final implementer on site to achieve complete efficiency. Should the placer at the site require further clarifications or information, we respond immediately to our clients or directly to the General Contractors/Concrete Contractors on their request. We can also discuss viable construction options during the detailing process and generate needed RFI’s and/or substitution requests prior to the drawings being submitted for approval.
By adhering to the specific standards and the needs of the client, we engineer shop drawings based on their priorities that include: reducing material wastage, saving man hours of rebar placement, fabrication man hours, ordering special grades of steel and any other logistical issues they may be faced with when moving the rebar to the project site.
Dimensional/General Arrangement Drawings
Along with providing accurate Rebar shop drawings; our core competence, we use this stage as an advantage to produce Slab Edge or General Arrangement drawings to general/concrete contractors.
These drawings are especially useful as they highlight the concrete edges, pour joints, tower crane openings, MEP blocks, depressions, steps, walls, columns, stair details etc. Once the Structural/Architects have included revisions approved by them, the drawings may then be used by fabricators, erectors and installers.
