Service Overview
Turning design information into coordinated drawing packages.
Tomy Engineering develops drawing information from approved project inputs and coordinates the interfaces needed for review, fabrication, installation, and construction.
The service is defined by the agreed discipline, deliverables, design responsibility, and review process. Drawing development supports the appointed project team and does not replace approvals, certifications, or licensed design authority required by contract or jurisdiction.
What we produce
Deliverables
Drawing packages structured for review and delivery.
General arrangement drawings
Coordinated plans, sections, and elevations that establish the overall technical arrangement.
Shop & fabrication drawings
Detailed drawing packages developed for fabrication and installation review.
Installation & coordination details
Interface details that align services, structure, finishes, equipment, and required openings.
Builders' work drawings
Openings, sleeves, supports, and associated requirements coordinated with the relevant disciplines.
Record drawing updates
Drawing updates based on approved construction information when record or as-built scope is included.
Technical drawing story
Drawing Development
From linework to controlled issue. Technical information is developed, checked, marked, and issued as one traceable drawing record.
Drawing disciplines
Drawing Disciplines
Support across coordinated building disciplines.
The applicable disciplines and level of detail are confirmed for each commission. Only services included in the agreed scope are provided.
- 01Architectural drawings
- 02Structural drawings

How we work
How We Work
A controlled path from information to issue.
Receive
Review the approved design, specifications, references, drawing register, and required issue milestones.
Develop
Prepare layouts, dimensions, details, interfaces, and technical annotations against the agreed scope.
Coordinate
Check the developing set against available discipline information, models, specifications, and site constraints.
Issue
Release a controlled package with an identifiable revision, status, comment record, and transmittal information.
Coordination & quality control
Coordination & Quality Control
Checked before each controlled issue.
Checks are performed against the information available at the time of issue. Review status and design responsibility remain visible rather than being implied.
- 01Drawing register, numbering, and sheet status
- 02Revision history and current-issue identification
- 03Dimension, level, reference, and annotation checks
- 04Cross-discipline interface review using available information
- 05Review-comment recording and response tracking
- 06Controlled issue and transmittal records
