Structural Grace, Inc. designed three light rail transit passenger stations on the 3.2 mile Northwest Extension of the light rail system and coordinated Valley Metro Rail’s standardized design elements with architectural, electrical and civil disciplines as well as integrated art elements. Design elements included reinforced concrete foundations and architecturally-inspired steel columns and shade canopies and louvers.
Structural Grace, Inc. designed three light rail transit passenger stations on the 3.2 mile Northwest Extension of the light rail system and coordinated Valley Metro Rail’s standardized design elements with architectural, electrical and civil disciplines as well as integrated art elements. Design elements included reinforced concrete foundations and architecturally-inspired steel columns and shade canopies and louvers. Responsibilities also included structural design of traction power substations, overhead catenary system (OCS) structures and communication and signal buildings for this CMAR project. Design requirements included updating previous calculations to meet the newly adopted City of Phoenix building code. Post design services were also provided. Working with the CMAR, Structural Grace provided Value Engineering of Valley Metro’s standardized station columns and foundations, design of drilled shafts for station columns, redesign of station columns (from built-up column to WF), redesign of the station column component connections and updated/modified existing contract drawings pertinent to these structural design changes.
Structural Grace, Inc. provided structural design and detailing services for a 60’x60’x20’ high structure as part of the artwork for Dunlap Station. This artwork structure provided shade and art elements that “funneled” the natural lighting around the station. The steel structure was designed with 20’ bays with intermediate framing at 10’ spacing and was designed to support both shade material and approximately 10 art pieces.

SGI designed the main steel frame, steel support pieces for the artwork and the connections to the main frame and provided post design services including special structural inspections.
Structural Grace, Inc. provided structural design and inspection services for the artwork installation at the Glendale Station. The artwork consists of a round steel column with ribbon steel that curves out and loops around to tie back into the column before looping out again (resembling a tree).

The artwork consists of a round steel column with ribbon steel that curves out and loops around to tie back into the column before looping out again (resembling a tree). Structural Grace analyzed the posts, ribbons, bracing, cables, foundations and anchorages and provided sealed plan sheets as part of this project.
Structural Grace, Inc. provided construction survey services for the new I-10/SR303 TI in the West Valley. The project includes a four level traffic interchange connecting I-10 Eastbound and I-10 Westbound and SR 303L NB and SR 303L SB, as well as 10 cast-in-place post-tensioned box girder concrete bridges and one precast, pre-stressed Type V AASHTO girder concrete bridge, along with numerous retaining walls, sound walls, and box culverts.
Structural Grace, Inc. is providing construction survey services for the Tempe Town Lake Downstream Dam. This dam is the world’s largest hydraulically-operated steel gate dam. The steel gate system will consists of eight fabricated steel gates mounted on a new concrete foundation and new reinforced concrete spillway slab approximately 100 feet downstream from the existing rubber bladders.

The steel gate system will consists of eight fabricated steel gates mounted on a new concrete foundation and new reinforced concrete spillway slab approximately 100 feet downstream from the existing rubber bladders. Each gate will be approximately 107 feet long and 17 feet high, weighing approximately 230,000 pounds. The new piers are about 9 feet wide on the upstream side and 4 feet wide on the downstream side.

Structural Design Tucson, Arizona
The Kino Parkway/22nd Street Intersection Improvement Project reconstructed one of the most congested intersections in Southern Arizona by installing the first grade-separated intersection in the City of Tucson. One of the unique challenges was elevating Kino Parkway over 22nd Street while maintaining traffic during construction! The new overpass replaces a signalized, gridlocked intersection with two continuous through lanes of traffic in each – north and south – direction. The bridges supporting these lanes are twin 344 foot, three span structures. This project creates an attractive and efficient gateway into Tucson. It was built with the public’s involvement, contributions and collaboration, including teamwork that brought government, businesses, design partners and citizens together to benefit the entire community.

The Luis G. Gutierrez-Cushing Street Bridge celebrates the reunification, both socially and physically, of Tucson’s west side communities and downtown area. This iconic structure, which is the first multi-modal (modern streetcar, vehicular, bicycle and pedestrian) public works project in Arizona, creates a destination and attraction as well as a critical linkage for parts of Tucson that were previously isolated.

The Luis G. Gutierrez-Cushing Street Bridge celebrates the reunification, both socially and physically, of Tucson’s west side communities and downtown area. This iconic structure, which is the first multi-modal (modern streetcar, vehicular, bicycle and pedestrian) public works project in Arizona, creates a destination and attraction as well as a critical linkage for parts of Tucson that were previously isolated. The bridge is built with the longest precast AASHTO girders ever cast in Arizona and sits on the longest drilled shafts ever used for an AASHTO girder bridge in Arizona. Complex architectural and artistic features are incorporated including steps from the deck sidewalks to the multi-use path below at all four corners of the bridge; bridge, step and wall railings made of pre-cast concrete and designed to replicate historic balusters; design, fabrication and erection of structural shade canopies over the promenades; and the incorporation of 12 local historically significant events in the shade structures and sidewalk deck creating an interactive experience for the visitor.
Structural Grace provided structural and bridge architectural design and Prime Project Management of a multi-disciplinary team for a six-span, 820 foot long, 270-foot cable-stayed curved steel pedestrian bridge.
Structural Grace provided structural and bridge architectural design and Prime Project Management of a multi-disciplinary team for a six-span, 820 foot long, 270-foot cable-stayed curved steel pedestrian bridge. The project included the bridge crossing at 19th Avenue near Greenway Road and 1,800 feet of multi-use path that closed the last remaining gap in the Sun Circle Trail System. This project was bid and awaits construction.
Structural Grace was the prime consultant for the roadway improvement of Bell Road between 94th Street and 98th Street. This project included the design of a new 270-foot, four-span bridge over the Reata Pass Wash, 1750 linear feet of new westbound roadway, and 1200 linear feet of new levees for Reata Wash.

This project also included the extension of two existing off-site drainage culverts, drainage improvements, new infrastructure for future ITS, new landscaping and curb, gutter, sidewalk and barrier improvements. Structural Grace worked closely with the City of Scottsdale to provide an economical bridge design that incorporated architectural elements. The architectural features were incorporated into modifications to the existing bridge giving both structures a similar appearance.
