Owners, architects, MEPs, and contractors trust our expert team to deliver thoroughly coordinated designs for low voltage, physical security, and life safety systems on their most complex projects.



Our Scope of work

IT backbone infrastructure reliability and scalability is imperative to the sustained success of an organization. Our certified network engineers design and engineer robust, high performance, and scalable IT systems. We help you look beyond current expectations and limitations to develop an infrastructure that is built with future growth in mind.

Low voltage systems are critical to safety and security and enable many of the most mission critical features inside buildings like wireless access, building automation, multimedia spaces, electronic safety and security systems, and other critical network based devices. Our firm gives low voltage systems the attention they require by focusing solely on them and not on the full suite of traditional MEP systems and components.

Our team understands the interdependencies required to design, engineer and implement reliable, efficient, and code compliant safety and security systems.  From traditional systems like electronic access controls, surveillance, video management and mass notification to highly customized solutions such as real time location systems, video analytics solutions, and automated threat detection, we deliver the safety and security systems that meet your objectives.

We create multimedia system designs that enable interactive presentation spaces, collaborative conference rooms and remote monitoring from command centers. Our designs focus on intuitive operation while delivering a wow factor to our clients and their customers.

Doors, frames and door hardware are evolving and have become increasingly more complex as automatic doors and network based electro-mechanical locking arrangements have become the norm. Our extensive experience in openings design and specifications spans over 30 years and we have saved clients millions of dollars in rework and project delays by coordinating their Division 08 design specifications with electronic safety and security systems.

Why use a specialist?

Our independent and focused approach to design engineering for Division 08 (Openings), 27 (Data & Communications) and 28 (Electronic Safety & Security) allows us to create and specify systems in an unbiased manner and tightly coordinate each dependency between the three scopes.  HSJ has no direct affiliations with any manufacturer or product. HSJ serves our clients’ best interests, not a  manufacturer’s bottom line.
