Discuss Your Project

Mechanical

Mechanical Engineering (HVAC)

HVAC System Design

We design heating, ventilation, and air conditioning systems tailored to your building's needs including equipment selection, ductwork layout, load calculations, and control strategies.

Load Calculations

We perform detailed heating and cooling load calculations using Manual J and Manual N methodologies to properly size HVAC equipment for reliable performance.

Ventilation Design

We design ventilation systems that meet California Title 24 requirements and ASHRAE standards, ensuring adequate fresh air supply and indoor air quality.

Energy Efficiency

We incorporate high-efficiency equipment, variable speed systems, heat recovery, and smart controls to reduce operating costs and meet California's energy standards.

Equipment Selection

We specify and coordinate HVAC equipment including furnaces, air conditioners, heat pumps, boilers, chillers, air handlers, and ventilation fans.

Electrical

Electrical Engineering

Power Distribution

Complete electrical systems including service sizing, panel schedules, circuit layouts, and load calculations with flexibility for future expansion.

Lighting Design

Lighting plans meeting illumination requirements, Title 24 energy compliance, and aesthetic goals with LED technology and daylight harvesting.

Life Safety Systems

Fire alarm systems, emergency lighting, exit signs, and backup power systems meeting California Fire Code and building code requirements.

Low Voltage Systems

Telecommunications, data networks, security systems, audio/visual systems, and building automation integration.

Title 24 Compliance

All electrical designs comply with California Title 24 Part 6 energy standards, including mandatory lighting controls and efficiency requirements.

EV Charging Infrastructure

Electric vehicle charging infrastructure with proper electrical capacity, safety features, and compliance with California's EV charging requirements.

Plumbing

Plumbing Engineering

Water Supply Systems

Domestic water systems including main service, distribution piping, fixture layouts, and water heater sizing for adequate flow and pressure.

Drainage Systems

Sanitary waste and vent systems, storm drainage, and roof drainage meeting California Plumbing Code requirements.

Gas Piping

Natural gas distribution systems for appliances, furnaces, water heaters, and cooking equipment with proper sizing and safety shutoffs.

Fire Protection

Fire sprinkler systems, standpipe systems, and fire department connections meeting life safety codes.

Water Conservation

Water-efficient fixtures, greywater systems, and rainwater harvesting to meet California's water conservation mandates.

Medical Gas Systems

Medical gas systems including oxygen, medical air, vacuum, and nitrous oxide distribution for healthcare facilities.

Energy Code

Title 24 Energy Compliance

California's Title 24 energy standards are among the most stringent in the nation. Our MEP engineering includes:

Energy modeling and compliance documentation
High-efficiency HVAC equipment specifications
Advanced lighting controls and daylight integration
Building envelope coordination
Solar PV system integration (when required)
Commissioning and verification requirements

We prepare complete Title 24 compliance reports (CF1R forms) for permit submittal and ensure your project meets all mandatory and prescriptive requirements.
