Shop Drawing Services for Subcontractors, Fabricators and General Contractors

Shop Drawing Services are detailed drawings prepared by or for the contractor, subcontractor or fabricator showing how a specific part of the work will be fabricated, assembled and installed, based on the contract drawings and specifications.

Shop drawings are where design intent becomes buildable detail. Bid Sharp prepares clear, dimensioned shop drawings from the architectural and structural documents so submittals are accepted the first time and crews build without guesswork. Drawings that require an engineer's seal are reviewed and sealed by an engineer licensed in the project's jurisdiction.

We work to the contract documents, identify conflicts early through RFIs and prepare complete submittal packages: shop drawings, product data, samples references and cover sheets that follow the specification's submittal requirements.

Shop drawings, submittals and the review process

A submittal is anything the contractor sends for review — shop drawings, product data, samples, mock-ups, calculations and test reports. The usual path is: register submittals from the specifications, prepare them, review by the general contractor, review by the architect and engineers, and an action of approved, approved as noted, revise and resubmit or rejected. We build packages that reduce the chance of revise-and-resubmit, and we handle resubmittals after comments. Read more in our guide to shop drawings vs submittals.

Trades we prepare shop drawings for

• Masonry shop drawings: coursing, reinforcing, lintels, control and expansion joints
• Tile layout drawings: patterns, centerlines, movement joints and trim
• Structural steel and miscellaneous metals: erection plans and connection details
• Reinforcing steel: placing drawings and bar lists
• Millwork, casework and architectural woodwork
• Storefront, glazing and door-and-frame schedules
• MEP coordination drawings: ductwork, piping and above-ceiling layouts

Coordination and RFIs

Good shop drawings find problems before fabrication: dimension conflicts between plans and sections, missing embeds, interferences with other trades and unclear finishes. We document these as RFIs with sheet and specification references, so the design team can respond quickly.

Standards and quality

Drawings are dimensioned, titled and indexed, reference the contract drawing and specification section and note deviations or substitutions clearly. They are delivered as PDF and editable DWG where required.

What you receive

• Plans, elevations, sections and details at readable scale
• Material schedules and bills of material
• Cut lists, bar bending schedules or layout sheets where relevant
• Submittal cover sheets and package index
• Submittal-ready PDF plus editable CAD when required
• Revision and resubmittal support

Technical scope and terminology we work with

• Shop drawings, fabrication drawings, erection drawings and installation drawings
• Submittal register, submittal log and transmittal
• Approved, approved as noted, revise and resubmit, rejected
• RFIs, coordination drawings and delegated design
• Product data, samples, mock-ups and calculations
• Contract drawings, specifications and approved equals

Who this service is for

Specialty subcontractors, fabricators and general contractors who need drawings prepared quickly without a full-time drafter.

How it works

1. Send contract drawings, specifications and relevant product data.
2. We confirm sheet count, scope and turnaround in the quote.
3. We draft, coordinate and send for your review.
4. We update the set after architect or engineer comments.

Software, standards and file formats

We work in PlanSwift and Bluebeam Revu for digital takeoff and markup, Excel and RSMeans-style cost data for pricing, Oracle Primavera P6 and Microsoft Project for scheduling, and AutoCAD-compatible formats for drawings. Deliverables are provided as Excel, PDF and, where relevant, DWG files, organized by CSI MasterFormat.

When to use this service

Use shop drawing services when a bid date is close, when your team is stretched across projects, when you need an independent check of your own numbers or drawings, or when you want consistent deliverables in the same format every time. Tell us the due date when you request a quote so the schedule can be planned around it.

Engagement options

• One project: order shop drawing services for a single bid or job and receive a firm price and turnaround before we start.
• Several trades or divisions: combine this service with related scopes so quantities, drawings and pricing agree.
• Bid-season capacity: send multiple projects with their due dates and we schedule the work to hit each one.
• Ongoing support: repeat-volume contractors can agree standard formats, cost codes and turnaround so every delivery drops straight into their process.

Quality control, confidentiality and communication

Every deliverable is reviewed by a second team member before it reaches you, and assumptions, inclusions and exclusions are written down so they can be checked. If information is missing we send a short list of questions rather than guessing, and we tell you which assumption we used when a question cannot be answered in time. Your plans, specifications and files are used only to prepare your project work and are not shared publicly; see our privacy policy.

Typical submittal review periods and sequencing

Specifications normally state how long reviewers have to act on each submittal and in what order they must be submitted — structural and long-lead items first. Planning backwards from the installation date, fabrication time and review time shows when each package must go out. We help build a submittal register and schedule so approvals do not hold up the field.

Delegated design and engineer-sealed drawings

Some specifications require the contractor to provide engineering for components such as metal stairs, precast, cold-formed framing or curtain wall. In those cases the shop drawings must carry calculations and a seal from an engineer licensed in the project's jurisdiction. We prepare the drawings and coordinate with the licensed professional.
