We are able to provide assessments, recommend alternatives, and provide high- functioning systems to meet clients' needs.

Our mechanical engineering services include all facets of heating, ventilation, and air conditioning such as split systems, packaged air conditioning, VAV systems, chilled/heated water systems, temperature controls, and building management systems.

Through our electrical engineering services, we provide highly functional environments that are safe and aesthetically pleasing. Our electrical expertise includes electrical service one-line diagrams, switchgear and circuit design, interior and exterior lighting, energy usage analysis, generator designs and specifications, fire alarm design and layout, school PA systems, telecommunication design, security system infrastructure design, and municipal/industrial control systems.

Our plumbing engineers design with the big picture in mind and strive to provide efficient and high-functioning solutions to clients' needs. While keeping the conservation of natural resources in mind, we offer plumbing services for waste water systems, domestic water and hot water systems, sump pumping systems, gas systems, vacuum systems, compressed air equipment, and piping design.



When it comes to providing quality services for our clients, we have the experience and expertise to complete the task. Our architecture department is a unique blend of architects, interior designers, and engineers that specialize in structural, mechanical, electric, plumbing, and civil design.

By being a full-service architecture firm, we provide our clients with all aspects of design, whether it is facilities assessment, master planning, site evaluation, facilities studies, schematic design, sketch plans, construction documents, construction administration, grant and bond planning, or interior design. Our architectural design is delivered with innovation, functionality, low maintenance and energy efficiency in mind.

Our wide range of experience and varied project past gives us the knowledge and resources to complete almost any type of architectural design. From minor renovations to complete school campuses, no project is too big or too small for GLS. Our background experience includes facilities from kindergarten to college campuses, public and municipal, churches, financial, commercial and retail, medical, and residential.

Successful design is achieved with the use of our in-house resources and close collaboration with our clients. We successfully respond to our clients' needs by uniquely expressing their wants and desires through our individualized and functional designs.
