7Solutions India structures quotations around the actual technical scope, deliverables, project information and collaboration requirements rather than publishing one generic rate for every engineering or detailing assignment.
Depending on the project, engagements can be structured as fixed-price work, time-and-material arrangements or recurring resource support.
Structural detailing, BIM, engineering and technical drawing assignments can vary significantly in complexity. A small revision package should not be priced the same way as a complete model-and-shop-drawing scope.
Our quotation process therefore considers the actual project documents, required outputs, technical responsibilities, revision expectations and delivery requirements before a commercial proposal is prepared.
The current page also refers to estimating by man-hours and item-based methods before a lump-sum quotation is established. That underlying approach is retained here without presenting internal estimating mechanics as a blanket guarantee. :contentReference[oaicite:1]{index=1}
The right commercial structure depends on how clearly the scope can be defined and how much the workload may change during delivery.
Suitable for a clearly defined scope with known deliverables, available project information and agreed responsibilities.
Best suited to defined drawing, modeling or detailing packages.Suitable where the required workload may evolve, information arrives progressively or technical support is difficult to define as one fixed package.
Useful for revisions, ongoing drafting and variable support work.Suitable for companies with repeat detailing, drafting, modeling or BIM workloads that require additional technical production capacity over time.
Commercial terms can be structured around the agreed engagement.A fixed-price quotation is most practical when the project scope can be reviewed in enough detail before work begins.
This model can provide a clear commercial reference for assignments where the inputs, outputs and responsibilities are sufficiently defined.
Some projects cannot be accurately defined at the beginning. Existing drawings may still be changing, revisions may arrive throughout the project or the required drafting workload may depend on ongoing engineering decisions.
A time-and-material arrangement can be more appropriate for these situations because the commercial structure can follow the actual technical effort performed within the agreed scope.
The same square footage or tonnage does not always represent the same detailing effort. Technical complexity matters.
Geometry, connection conditions, interfaces and drawing density can significantly influence required technical effort.
Complete and coordinated source information generally reduces clarification and revision work.
A 3D model, shop-drawing package, schedules and fabrication documentation require different levels of production effort.
Changes after initial drawing or model development may affect the scope depending on their extent and timing.
Project-specific platforms, file formats and templates can influence setup and delivery requirements.
Multi-discipline model coordination and technical interface review can require additional project effort.
Pricing can depend on project complexity, member count, connection conditions and required shop/erection documentation.
Steel Detailing →Pricing depends on the required fabrication-document depth, assemblies, member types and project information.
Steel Shop Drawings →Modeling discipline, required model development, coordination and deliverable requirements influence BIM pricing.
BIM Services →Reinforcement complexity, drawing coverage and scheduling requirements can affect the detailing scope.
Rebar Detailing →Component types, reinforcement, embeds, shop drawings and erection requirements influence precast estimating.
Precast Detailing →Analysis depth, design inputs, calculation requirements and technical documentation determine the engineering scope.
Engineering Services →Design revisions are common in engineering and construction projects. The commercial impact depends on whether the change falls within the original agreed scope or introduces new work.
The current page specifically states that design changes and hard-copy requests may attract separate charges. :contentReference[oaicite:2]{index=2} The modern version keeps the principle but avoids presenting every possible extra cost as a universal contractual term.
Payment schedules, invoicing arrangements and accepted payment methods are best confirmed in the commercial proposal for each project or client relationship.
The current page publicly states seven-day credit, wire transfer, PayPal and a no-upfront progressive-payment model. :contentReference[oaicite:3]{index=3} Unless those terms are intended to be universal and permanent, I recommend removing them from evergreen website copy.
This keeps the page accurate even if commercial policies change later.
Providing representative drawings and a clear scope helps us understand the level of detailing, modeling or engineering work required.
For an active project, use the Project Inquiry page to send the relevant information for technical review.
Pricing is based on the technical scope, project complexity, required deliverables, available input information and expected project workflow.
A fixed-price quotation can be appropriate where the scope, project information and deliverables are sufficiently defined.
Time-and-material arrangements can be suitable for ongoing, variable or revision-heavy technical work where the final workload cannot be defined accurately in advance.
It depends on the agreed scope. Minor included revisions and larger out-of-scope design changes should be defined in the project quotation or commercial agreement.
Project drawings, scope information, required deliverables, software requirements and the expected schedule are useful starting points for estimating the work.
