We specialize in three core areas:

  • Mechanical, Electrical, Plumbing (MEP) engineering
  • construction management
  • strategic value-added professional services.


We create design solutions that maximize every aspect of facility. Our solutions have a positive impact on the environment and energy use, and enhance comfort and safety. We provide innovative engineering solutions thanks to our engineers – the best and brightest in our industry. Our MEP project experience includes:

  • design of MEP equipment systems for new construction
  • large scale renovations
  • tenant property improvements
  • HVAC retrofit, security, and control systems
  • multi-unit residential wood frame construction
  • mixed use commercial properties, condominium, schools, and warehouses

Professional Affiliations Bring Value to Our Clients

GPSG maintains professional membership with industry leaders such as: American Society of Mechanical Engineers (ASME), ASHREA, Project Management Institute (PMI), Associated Builders and Contractors (ABC), and U.S. Green Building Council. With our professional affiliations, we’re on top of new research and innovation in art, science, engineering and technology to bring you the best value. We assist with the design and calculations required for LEED accreditation, Life Cycle Cost Analysis, sustainability, and energy- and water-efficient design in our projects.

GPSG’s design engineers use AutoCAD, BIM, and Revit design toolsets to create accurate construction-ready drawings that represent real time information that cover details of all sections of building systems including . Our knowledge of technical systems operation allows us to contribute to resource-effectiveness, sustainability, and overall cost savings. GPSG’s MEP engineering design services are performed through pre-construction, design, and build phases. GPSG’s process starts by working with the project owner, architect, and stakeholders to identify the potential risks or constraints early on This teamwork results in meeting project delivery schedules, staying within budget, and meeting quality standards. Our team designs for the comfort of the end user, the budget of the project owner, and ease of construction. We offer the following range of services:

  • Pipe sizing and layout
  • HVAC duct design and layout
  • Energy analysis and modeling for LEED certification process
  • Load calculations
  • HVAC equipment selection and layout
  • Schedule for equipment
  • AC duct design and layouts
  • Ductwork drawings and detailing
  • HVAC consultation services
  • Preparation of 2- and 3-dimensional construction documents using AutoCAD and Revit
  • Design building automation temperature control systems complete with control sequences, diagrams, passive cooling system, and point lists
  • Stamped permit-level drawing assistance

We offer a wide range of HVAC engineering and design services for various kinds of heating such as central, forced air, hydronic, hot water, radiant, central air, and home heating. We provide complete heating, ventilation and air conditioning engineering services for a variety of needs. Our engineering team works with owners and architects to design and implement state of the art, most efficient HVAC solutions for your construction and renovation projects.

Clients depend on us to design and deliver smart and integrated engineering solutions for high performance and efficient utilization of capital investments. We use a continuous process improvements methodology to generate quality solutions.



We provide complete design and integration solutions for different types of controls projects. In addition to general building automation, we specialize in control system design for commercial facilities. This includes waste-water treatment plants, water treatment plants, boiler and chiller plants, power generation plants, and various process systems. We strive to develop control systems that make business sense. We do not solely focus on the technology; we also look for how automation can maximize efficiency and profitability.

Our integrated electrical engineering services also include:

  • Power supply and distribution design
  • Control systems design
  • Security and access systems design, CCTV systems
  • Detection and alarm systems design
  • Interior and exterior lighting design
  • Information and telecommunication systems design
  • Fire detection and alarm systems design


At GPSG, our plumbing engineers are highly involved in planning, designing, and installing of systems to ensure safety and security. Some of our specialized works include storm water systems, sanitary sewer, plumbing fixtures, and hot water systems illustrated in the following project pictures. Our design engineers and CAD technicians can design any piping system required for any end-user.

With our many years of experience of plumbing engineering, our staff apply appropriate and current codes, select cost-effective materials and technology and work closely with architects on slopes for successful project outcomes.



We take into consideration all the essential details of the project. What is your objective, and at what scale are you willing to operate? We will address all your office and field concerns and work closely with you to create a team based on your requirements. We provide construction management services for a variety of industries, from municipal roads and utilities to highway and building/facility infrastructure design-build projects. Our dedicated team works closely with the client, contractor, suppliers, design-build engineers, and stakeholders throughout all phases of the construction process to ensure that costs, schedule, safety, and quality are managed and controlled.
