MEP

MEP drafting & engineering

Our MEP drafting services deliver accurate, coordinated, and construction-ready Mechanical, Electrical, and Plumbing drawings for projects across the United States. From permit-support documentation and multidisciplinary coordination to engineering calculations and energy compliance, we provide comprehensive solutions that support every stage of the construction process. Whether your project requires California Title 24 compliance, HVAC load calculations, electrical load analysis, plumbing calculations, or jurisdiction-specific code documentation, our team develops precise MEP packages tailored to local regulations and project requirements. Every drawing is prepared to improve constructability, streamline coordination between trades, support permit approvals, and ensure efficient project execution.

Final engineering certification/sealing is provided by appropriately licensed professionals where required.

Our Engineering Calculation Services

California Title 24 Energy Compliance

Comprehensive Title 24 documentation for residential and commercial projects, including energy compliance reports, lighting compliance, HVAC efficiency calculations, and building envelope analysis required for permit approval throughout California.

Manual J Load Calculations

Accurate residential heating and cooling load calculations to properly size HVAC equipment based on building orientation, insulation values, occupancy, windows, climate zone, and internal heat gains.

Manual S Equipment Selection

Proper HVAC equipment sizing and selection using ACCA standards to ensure systems meet the calculated heating and cooling loads without oversizing or undersizing.

Manual D Duct Design

Professional duct sizing and airflow calculations designed to optimize air distribution, maintain static pressure, and improve HVAC system efficiency.

Commercial HVAC Load Calculations

Detailed cooling and heating load analyses for office buildings, healthcare facilities, retail spaces, warehouses, educational institutions, hospitality projects, and industrial facilities.

Lighting Power Density (LPD) Calculations

Lighting energy calculations to verify compliance with applicable energy codes, including lighting fixture schedules, controls, and allowable power densities.

Electrical Load Calculations

Electrical demand and service load calculations for residential, commercial, and industrial facilities, including panel sizing, feeder calculations, transformer sizing, and service entrance design.

Short Circuit & Coordination Studies

Engineering studies to determine available fault current, protective device coordination, and equipment ratings for safe and reliable electrical system operation.

Voltage Drop Calculations

Electrical system analysis to ensure voltage remains within acceptable tolerances throughout distribution systems while maximizing operational efficiency.

Plumbing Fixture Unit Calculations

Domestic water supply and sanitary drainage calculations based on fixture unit demand to ensure proper pipe sizing and system performance.

Stormwater & Roof Drainage Calculations

Hydraulic calculations for roof drainage systems, stormwater piping, and site drainage to meet applicable plumbing and municipal requirements.

Ventilation & Fresh Air Calculations

Outside air and ventilation calculations prepared in accordance with ASHRAE standards to ensure occupant comfort, indoor air quality, and code compliance.

Energy Modeling & Building Performance Analysis

Whole-building energy modeling to evaluate energy consumption, optimize building performance, and support green building initiatives, utility incentive programs, and sustainability goals.

Why us

What makes us effective

Successful MEP design depends on coordination. Our integrated Mechanical, Electrical, and Plumbing team works together so every system is carefully coordinated before construction begins, minimizing clashes, reducing costly revisions, and improving installation efficiency on site.

We take ownership of the coordination process, treating every project as our responsibility rather than simply delivering drawings. By proactively identifying conflicts, optimizing system layouts, and ensuring compliance with applicable codes and project requirements, we help contractors, developers, and engineers move confidently from permitting to construction.

Our commitment to accuracy, accountability, and seamless collaboration allows us to deliver coordinated MEP documentation that reduces the margin for error, streamlines project execution, and supports successful outcomes on projects of every size.
