San Engineering Structural Projects

Denver Union Station, Pre-Construction Structural Survey

San Engineering performed detailed inspections of all bridges, buildings, railroad track, and roadway infrastructure surrounding the new Denver Union Station site, prior to groundbreaking. Photographic and videographic documentation of all existing cracking and distress was gathered, for the purposes of avoiding future claims against the Owner. The Owner was a consortium of CDOT, RTD, and the City & County of Denver.

Central Park Blvd. Bridge over I-70, Denver, Colorado

Independent design check of a new 2-span, 11-lane bridge over I-70. The project included the bridge and 6 retaining walls. Detailed independent calculations and structural detail checks were performed.

Blue River Bridge

Blue River Pedestrian Bridge. Silverthorne, Colorado - San Engineering performed the structural design of a 210 feet single span pedestrian bridge over the the Blue River. A floodplain study and utility design for a public restroom were also part of this project.

Pump Seismic Analysis

Pump Seismic Analysis, Pueblo, Colorado -

Anchorage design for equipment (pumps, etc.). Bechtel’s “Engineering Specification for Seismic Protection of Equipment” requires the suppliers of equipment to provide the structural design of the equipment’s anchorage and the associated report in accordance with this specification.

Seismic analysis and structural qualification of Seismic Category I equipment. This specification requires the equipment suppliers to perform a detailed stress analysis of their equipment if it is listed as Seismic Category I. Through our work, we have developed a comfortable rapport with the Bechtel PCAPP engineering staff, and consistently navigated the process and intricacies common to equipment with Seismic Category I classification. Our submittals are typically granted a “Code I” status upon their first review.

Second Creek Trail

San Engineering provided civil and structural services for a 2.5 mile in Commerce City. Some of the services included the design of four pedestrian bridges, culvert sizing, and erosion control plans.

23rd Avenue Bridge

San Engineering performed design of a triple-cell precast culvert bridge over the overflow channel of the South Platte River. The bridge, intended to be a centerpiece for a new development, included a number of detailed architectural enhancements including ornamental railings, architectural concrete pillars, and decorative lighting.

35th Avenue Bridge

San Engineering performed the design of a new 9-span, 1250-foot long bridge carrying the extension of 35th Avenue over the South Platte River floodplain. The project included the completion of an exhaustive alternatives analysis study in order to identify the most economical structure type and span arrangement.

CORR Bridge Replacement

San Engineering is responsible for the design of a new bridge replacing a structurally-deficient bridge in Fountain, Colorado. The existing 3-span bridge will be replaced with a single-span prestressed concrete girder structure on driven steel pile foundations. The new roadway profile will be raised by approximately 2’-0”, to allow for 100-year flows to pass unimpeded.

Plum Creek Trail Phase III Bridge and Retaining Wall Design

San Engineering performed Civil and Structural Engineering for Phase III of the Plum Creek Trail for the Town of Castle Rock. The project included an evaluation of “bridge versus box culvert” for a crossing of Sellars Gulch, east of the confluence with East Plum Creek. The project also included the design of over 20 retaining walls. The wall types varied depending on location and application. Retaining walls included Mechanically-Stabilized Earth (MSE) as well as cast-in-place concrete.
