Design & Engineering
Electrical infrastructure projects require accurate documentation, detailed system design, and coordinated engineering deliverables to ensure successful execution. Three Phase Tech Services provides comprehensive design and engineering services covering electrical documentation, system architecture design, and BIM modeling. Project managers, consulting engineers, and contractors rely on these services to streamline approvals, reduce construction errors, and deliver projects on schedule.
Why This Service Matters
Incomplete or inaccurate engineering documentation leads to construction delays, coordination conflicts, and costly rework. Proper design and documentation upfront ensures that electrical systems are correctly sized, properly coordinated with other trades, and compliant with applicable codes and standards.
Problems Addressed
- Missing or outdated single line diagrams creating confusion during construction
- Inaccurate load schedules leading to undersized equipment
- Lack of coordination between electrical and other building systems
- Approval delays due to incomplete or non-compliant documentation
- Construction errors from unclear or inconsistent drawings
- Difficulty integrating metering and energy management systems
Potential Outcomes
- Accurate electrical documentation supporting efficient construction
- Properly sized equipment based on detailed load analysis
- Coordinated designs minimizing conflicts with other trades
- Faster approvals through compliant and complete submissions
- Reduced construction errors and rework
- Integrated system architectures for metering and automation
Design Engineering
Specialized services address different aspects of electrical design documentation and system engineering. Each service can be delivered independently or as part of a comprehensive design package.
Development of load schedules, single line diagrams (SLD), and power control schematics providing the electrical documentation needed for planning, construction, and regulatory approvals.
Design of system architectures for energy management systems, metering infrastructure, and building automation integration to enable monitoring, control, and optimization of facility operations.
Building Information Modeling (BIM) services for electrical systems including 3D modeling, clash detection, coordination with other MEP trades, and construction documentation in Revit and other BIM platforms.

Frequently Asked Questions
What information is needed to start a design project?
Design projects typically require architectural drawings, project specifications, equipment schedules, utility information, and any existing electrical documentation. Specific requirements depend on project scope and deliverables.
Can you work with existing documentation from other consultants?
Yes. Design services can build upon or update existing documentation from other sources. Review of existing materials is performed to identify gaps and ensure consistency.
What Level of Development (LOD) do you provide for BIM projects?
BIM models can be developed from LOD 100 (conceptual) through LOD 400 (fabrication-ready) depending on project requirements. LOD is defined in the BIM Execution Plan at project initiation.
Do you provide authority submission support?
Yes. Documentation can be prepared to meet specific authority requirements including DEWA, SEWA, ADDC, and other regulatory bodies. Submission coordination and response to comments can also be provided.
Can designs be coordinated with other MEP disciplines?
Yes. BIM coordination services include clash detection and resolution with mechanical, plumbing, and fire protection systems. Coordination meetings and issue tracking are part of the service.
What software platforms do you use?
Primary platforms include AutoCAD, Revit MEP, and Navisworks. Other platforms can be accommodated based on client requirements and project needs.
Do you provide calculations and engineering analysis?
Yes. Design services include load calculations, cable sizing, voltage drop analysis, short circuit calculations, and other engineering analysis required to support the design.
Can you update as-built documentation after construction?
Yes. As-built documentation services include updating drawings and BIM models based on field-verified conditions and redline markups from construction.
