SJH Engineering, P.C.

SJH Engineering, P.C. is a consulting engineering firm founded in 2006 and headquartered in Princeton, New Jersey, working across the New York and New Jersey metropolitan region. The practice concentrates on transportation and civil infrastructure, including rail and transit structures, bridges, construction inspection and construction management support for public agency clients. SJH is named as an engineering consultant on the Metropolitan Transportation Authority’s Park Avenue Viaduct replacement in Manhattan, a program that rebuilt 196 bridge structures and more than 12,600 feet of railroad across 28 weekend outages without suspending Metro-North service. The firm employs between 51 and 200 people and offers structural and civil engineering, inspection and construction management services.

SJH is larger and more multi-disciplinary than a transportation consultancy label suggests. The firm reports a team of more than 90 professionals working from offices in New Jersey, New York and Georgia, covering structural, civil and MEP engineering alongside architectural, geotechnical, construction management and construction inspection services.

The certification stack matters on public work. SJH is a certified SBE, MBE and DBE firm in multiple states, which the company frames not only as its own standing but as a way of helping prime consultants and contractors meet subcontracting goals. For an agency client that is a procurement fact before it is anything else.

The published scope is written in NAICS codes rather than marketing categories, which is a tell about who the firm sells to: 541330 Engineering Services, 541310 Architectural Services, 541320 Landscape Architectural Services, 541340 Drafting Services and 541350 Building Inspection Services. Those are the lines an agency uses to write a task order.

The building types are buildings, bridges, transit structures and highways, with design, construction inspection, construction management and construction support offered across each. Carrying inspection and construction support alongside design is the difference between a firm that hands over drawings and one that stays through the field problems, and on rail and transit work the field problems are where the schedule lives.

Client feedback published on the site points at the same trait. On one project, an architect noted that SJH carried work through to completion that another firm had started years earlier. On the Pier 24 temporary support scheme, an engineering consultant described a value engineering proposal that grew into a very complex submission, and credited SJH with keeping the process moving while holding engineering costs down, which was what got the proposal approved. Temporary support design is the kind of scope that gets more complicated the further into it you go.

The firm has grown steadily since 2006 and attributes that to quality and expertise rather than acquisition. Its Princeton office is at 3700 Route 27, Suite 201, with New York at 131 West 33rd Street on the 16th floor.
