Precast concrete detailing

Precast Double Tee Detailing Services

Coordinated production and erection drawing support for precast double tee floor and roof units used in parking structures, commercial buildings and large-span facilities. Our detailing scope helps precast producers and project teams document member geometry, strand and reinforcement information, embeds, connection interfaces and placement plans against approved engineering documents.

What we detail

Production-focused double tee drawing packages

Details are prepared from project-specific geometry, approved design information, fabricator standards and applicable drawing conventions.

Double Tee Shop Drawings

Unit-by-unit production drawings covering flange and stem geometry, lengths, openings, recesses, edge conditions and casting references.

Prestressing & Reinforcement Layouts

Document engineer-provided strand patterns, conventional reinforcing, end-zone details and reinforcement schedules for fabrication review.

Embedded Plates & Hardware

Coordinate cast-in plates, inserts, ferrules and connection hardware locations with support details and adjacent members.

Bearing & Connection Details

Prepare drawing details for bearing seats, connection interfaces, joint conditions and specified weld or fastening information.

Erection & Marking Plans

Generate level-by-level placement plans, unit marks, orientations and support relationships using the approved erection scheme.

Material Schedules & Revisions

Support piece schedules, quantities, drawing issue logs, coordinated markups and authorized revision incorporation.

Typical output

Drawings organized for plant and site coordination

The agreed package may include the following, depending on the producer's workflow and engineering responsibilities.

  • Double tee shop tickets with identification and member dimensions
  • Sections, elevations, profiles, flange openings and recess details
  • Prestressing and conventional reinforcement information supplied for detailing
  • Cast-in plates, inserts, handling hardware and embed location schedules
  • Bearing, edge, topping and adjacent-member interface drawings
  • Erection and marking plans, unit lists and placement orientations
  • Reviewed redlines, issue history and updated fabrication documentation

Working method

A coordinated path from design inputs to drawing issues

Drawing assumptions and discrepancies are referred back to the client or responsible designer before they affect production information.

Review source information

Check issued plans, precast requirements, support details and producer conventions.

Detail members & embeds

Develop unit geometry, production sheets and specified reinforcement and insert locations.

Coordinate interfaces

Compare bearing, joint, adjacent trades and erection-plan information; document open questions.

Resolve revisions

Incorporate authorized comments, maintain mark consistency and issue controlled files.

Engineering responsibility

Drawing accuracy and design adequacy are separate approvals

Member capacity, prestress losses, bearing reactions, fire performance, lifting stresses, temporary support and connection adequacy depend on the approved design basis, fabrication method and erection sequence.

Structural calculations, prestressing design, reinforcement selection, lifting-anchor design, temporary stability, code compliance and any required professional certification remain with the engineer of record, precast specialty engineer or other authorized design professional. Drafting files must receive the applicable project approvals before fabrication or installation.

Frequently asked questions

Precast double tee detailing FAQs

What is included in a double tee shop drawing?

A typical shop drawing identifies the unit mark, flange and stem dimensions, relevant sections, embeds, openings, engineer-provided strand and reinforcement information, and notes needed for review or production.

Can the package include parking deck erection plans?

Yes. Erection and marking plans can show unit positions, orientations, support references and connection coordination using the approved structural and erection information.

Who determines prestressing strands and lifting details?

Strand selection, prestressing calculations, lift-point design and handling stability are engineering decisions. We can document the information supplied and authorized by the responsible precast engineer.

Which project files should be submitted for a quote?

Share current structural and architectural plans, unit schedules, precast specifications, approved design or typical details, project delivery requirements and expected drawing formats.
