Seattle Department of Transportation NE 45th St. Viaduct Seismic Retrofit Design (2015-2017)

As a subconsultant, RHC Engineering provided seismic retrofit analysis and concept retrofit design for this highly irregular reinforced concrete structure. RHC identified existing lateral load path, evaluated critical vulnerability components, and provided retrofit concept for the new lateral load path. The east approach bridge is a structure with complex geometries. It includes three units: Unit 1 is a reinforced concrete multi-cell box structures with battered precast prestressed concrete piles, Unit 2 is a reinforced concrete T

beams structures supported by plum precast prestressed concrete driven piles. Unit 3 is an extremely curved reinforced concrete box structure supported by precast prestressed concrete driven piles.

Seattle Department of Transportation Bridge Load Rating (2016)

As a prime consultant, RHC Engineering provided load rating for this two span reinforced concrete bridge. RHC did field verifications of the bridge condition. The rating analysis considered construction staging and SDOT’s special hauling truck. RHC also did independent QA/QC checks by comparing computer software output with hand calculations.

Seattle Department of Transportation Cowen Park Bridge Structural Assessment (2017)

The Cowen Park Bridge is a deck arch bridge on the busy 15th Avenue NE near the City of Seattle’s University District. The 378-foot long bridge is composed of a 160-foot long main span deck arch with 8 spandrels, 158.5-foot long south approach spans, and 59.87-foot long north approach spans. The deck is a solid reinforced concrete slab and shows longitudinal cracks throughout underside of the bridge. Using CSI SAP2000 software, RHC performed refined three dimensional finite element analysis, including plate and shell elements for this bridge under strength and extreme event limit states. Live lane loads were applied to the deck therefore no load distribution factors were needed. RHC identified deficient elements and recommended ductile and non-

ductile retrofit strategies with the consideration of protecting the historical columns with unique architectural features. RHC’s refined analysis went beyond the contract scope to capture the bridge behavior with highest accuracy and to satisfy the clients’ specific needs for this project.

Washington State Department of Transporation SR520 Westside Corridor (2014-2018)

RHC’s structural scope of work for this project included designing two pedestrian bridges that are about 400 foot long curved and post-tensioned box structures, one approximately 200 foot long pedestrian tunnel, over 20 retaining walls, one HOV ramp vehicular bridge designed for future light rail compatibility, storm water structures, refining structural design criteria, and seismic analysis.

Washington State Department of Natural Resources Lower High Point Bridge (2014-2015)

As the prime consultant, RHC Engineering provided plan, specification, and cost estimation for the 30%, 90%, 100%, and ready for bid package of the new replacement bridge. The new bridge is a 200 foot long self-weathering steel truss structure. Due to the difficult site condition, the bridge was designed to accommodate constructability requirements by splicing the truss segment and designing for field bolting.

City of Bainbridge Island City Bridge Inspection (2016)

A single span steel truss, this 250 foot long pedestrian bridge is parallel to Highway 305 and is part of the City of Bainbridge Island’s trail system. RHC performed field inspection and structural assessment for this bridge. The steel tube members, connections, and abutment anchor bolts were inspected and assessed. Several safety improvements were suggested. A unique challenge for this project was performing structural analysis with limited as-built data. The assessment was made by engineering judgement, field measurement of member sizes, and referring to the reaction forces on the foundation design plan.

Another timber pedestrian bridge was inspected and analyzed. The inspection included visual observation, hammer sounding, pick and drilling. The inspection found a tilt pile, glulam girder cracks, and wood piles split. The structural analysis found that all major superstructure components have capacities lower than the current design codes. The structural assessment recommended that the bridge needs to be replaced.

Seattle City Light Crane Building Seismic Evaluation (2016)

One alternative the project team worked on was to install new substation transformer equipment onto the roof of the exiting 60 foot tall Crane Building. A major concern was seismic vulnerability. RHC performed as-built data review and preliminary seismic analysis and identified that major deficiencies of the building were on the footings. RHC recommended retrofit strategies with planning level cost data.

Washington State Department of Natural Resources Lower High Point Bridge Replacement Design (2014-2015)

The Washington State Department of Natural Resources (DNR) was planning to build a new bridge to replace the existing Lower High Point Bridge, which was damaged during a flooding in January 2009. The bridge is located 1.2 miles southeast of High Point Trailhead, the south side of Interstate 90 Exit 20. As the prime consultant, RHC Engineering provided plan, specification, and cost estimation for the 30%, 90%, 100%, and ready for bid package of the new replacement bridge. The new 200 foot long self-weathering steel truss bridge replaced the damaged timber bridge. The project management includes

providing construction schedule, developing standalone construction specifications, cost estimation, addressing DNR review comments, coordinating with the geotechnical subconsultant, and responding to the contractor’s RFIs.

Seattle Department of Transportation Post Ave Bridge Removal (2015-2018)

Removal of existing Post Avenue Bridge, and construction of new pavement on the deep soft soil near the Seattle’s waterfront, may impact the adjacent buildings’ structural safety, when the existing soft soil is under new overburden loads. RHC managed and led the structural engineering and geotechnical engineering services for this project. The scope of work included evaluating existing historical masonry building structures, proposing pavement reconstruction procedures, coordinating with the

geotechnical subconsultant, attending project meeting and addressing City’s review comments.

Seattle Public Utilities (SPU) Modular Buildings Upgrade (2014)

The existing SPU crew buildings were built as temporary structures around 2010. As they will be used longer than anticipated, the structures needed to be checked against the code requirements of permanent buildings and be corrected if necessary. SPU will remove them in the future, so a cost-effective way to improve the existing structures was desirable. The scope of work included vertical and lateral analysis of foundation demands, foundation improvement to be compliant with current codes, design connection between attached non-structural stair and ramp to the building structures, and a check of the fire code for one building due to its closeness to an adjacent utility building. As the prime consultant, RHC Engineering successfully delivered design, permit

assistant, bid assistance, construction support, and post-construction records. Project management activities including permit applications, preparing construction cost estimation and assisting during bid, attending pre-

RHC Engineering provided detailed constructability review for 90% shoring design of the Denny Way Substation structures. The review included 38 plan sheets and relevant construction specifications. RHC Engineering is also providing the construction document control for this project.

Seattle City Light Elliot Bay Seawall Construction (2014)

The construction of Elliot Bay Seawall in Seattle’s waterfront involved complicated utility work challenges. A concrete utility duct bank under Pier 56 needed to be demolished and relocated without interruption of normal day time use. RHC Engineering provided design and construction support services for a construction platform to support the utility work. The design is not typical due to the daily tidal changes under the pier, the non-damage requirement of the private Pier 56 structures, the difficulty of construction access, as well as the limited information of the existing structures. The structure was supported by friction collars on existing piers and post-installed anchors into the Elliot Bay Seawall. A steel beam alternative and a glulam wood beam alternative were provided for

the most cost-effective solution.

Other services for this project included structural engineering for electrical duct supports on the existing waterfront pier structures. RHC provided structural design for the heavy duty electrical ducts that were to be mounted on existing timber structures or concrete piers. Due to the non-destructive requirements, some mounting design used cable wires that were tightened to the wood beams or concrete piers. RHC provided engineering analysis and design for size of cables, sag of cables, and connection capacities.

Port of Seattle 400 HZ Gate Improvement (2017-2018)

RHC Engineering provided structural engineering design for multiple electrical equipment on the boarding bridges for the Port. RHC performed field visit, verified existing conditions, and accommodated construction change requests. Seismic effect was considered. RHC’s engineering submittal assisted smooth construction of the electrical equipment.
