Yale Elementary School Gymnasium

Thursday, August 15th, 2013

Erickson Structural was retained to design the structural modifications and seismic upgrades to the existing Yale Elementary School gymnasium in Ariel, Washington.  The Woodland School District requested that the seismic upgrade be designed to meet an enhanced performance objective, namely Life Safety for the BSE-2 design earthquake, according to ASCE 41 standards.  Non-seismic structural modifications were designed to satisfy the applicable portions of the 2009 International Building Code (IBC) with Washington amendments.  The existing roof structure has been replaced with a new roof structure designed to support a snow load that exceeds the code minimum, based upon local reports of past snow accumulation for the area.

This project has successfully been completed and this refreshing upgrade to this existing building  will provide years of enjoyment and use to the children of Yale Elementary and the community.

The Church of Jesus Christ of Latter-day Saints

Thursday, December 13th, 2012

Erickson Structural provided structural engineering services for the design of a new 6,200 square foot addition to the existing meetinghouse for The Church of Jesus Christ of Latter-day Saints located in Jefferson, Oregon. Both the original building and the new addition are supported by a foundation system comprised of cast-in-place concrete piers and grade beams.  Erickson Structural provided structural engineering support during the construction of the addition by conducting structural site observations, responding to contractor’s requests for information and reviewing shop drawings and submittals from the contractor.  This addition was successfully completed in 2013.

Woodburn Construction Company is the contractor and McSwain & Woods Architects & Planners is the architect for this project.

Esther Short Park Bell Tower

Friday, October 19th, 2012

Erickson Structural designed the structural aspects of the improvements to the Esther Short Park Bell Tower, intended to provide the City of Vancouver employees with OSHA-compliant access to the bell tower for maintenance purposes.  The improvements included a new, steel-framed access platform and a ladder connecting the new platform to an existing platform, both of which are located near the top of the bell tower.  The new platform rests upon an existing tube steel frame used to support the bells within the tower.  The new platforms are accessed via an external lift crane to which employees tie-off, then step onto the platform while still clipped to the crane, and then clip onto a new D-ring on the bell tower to transfer.  This arrangement allows employees to remain harnessed in at all times, avoiding the need for a safety guardrail around the perimeter of the bell tower.

Dr. Russ Church Dental Office Building

Thursday, October 13th, 2011

The wood-framed, 3,500-square feet addition to the Salmon Creek Plastic Surgery building in Vancouver, Washington, functions as the dental offices for Dr. Russ Church. Erickson Structural provided structural engineering design services to Clark Kjos Architects, and actively participated in the construction phase.

The building addition was designed to seamlessly blend with the existing medical office building, constructed circa 2009, utilizing consistent construction, details and exterior finishes.  To the public, the composite building now appears to have been constructed in a single project, an important design and project objective.

The building is primarily wood-framed, except for the wall between the two building phases, which is constructed of masonry to satisfy fire code requirements.  Except for the use of a common foundation at the interface between the new addition and the existing building, the two phases of the building are structurally independent.  Because the two building phases are structurally independent, the structural design of the addition included a seismic separation between the existing building and the new addition to prevent “pounding” during an earthquake.

St. Paul High School

Wednesday, May 11th, 2011

More than 30,000 square feet of the interior of the St. Paul High School, in St. Paul, Oregon, underwent an extensive renovation while a 4,000 square-foot addition was built to house science classes. Erickson Structural personnel functioned as the Engineer of Record on this project, which included site observations and responses to contractor inquiries and to City or County officials .

 

 

Gateway Community Church

Wednesday, January 26th, 2011

Erickson Structural personnel provided structural engineering design of this new, 17,000 square foot facility for the Gateway Community Church in Washougal, Washington. The building included a new church sanctuary, classrooms, and office space adjacent to the existing church, which also underwent renovations. The roof structure of the new sanctuary was framed with architecturally exposed, heavy timber glue-laminated trusses.

The new church was designed to “interact” with the existing, adjacent church, and to be flexible enough to accommodate the eventual demolition of the existing church to allow for the construction of its replacement.

Beaverton Bike Gallery

Tuesday, November 23rd, 2010

Erickson Structural personnel developed a complete structural renovation, plus a 600 square foot expansion, using two drawing packages (interior and exterior), to allow interior construction to begin while exterior design was still underway. During construction, Erickson Structural personnel identified an economic opportunity to perform seismic strengthening at greatly reduced cost due to increased access during the renovation.

Because original construction drawings for the building were not available, Erickson Structural personnel were required to develop as-built drawings based upon detailed documentation of the existing structure.

McMenamins Tavern and Pub Expansion, NW 23rd Avenue

Monday, November 22nd, 2010

Erickson Structural personnel provided structural engineering design to expand the first floor of an early 1900’s-era, two-story, wood-framed building to accommodate the growth of this popular structure.  Erickson Structural personnel performed exploratory testing with the contractor to expose the structure, determine existing conditions, and develop as-built drawings.  Erickson Structural personnel worked closely with the City of Portland to incorporate required seismic upgrades, and to identify voluntary upgrades that could be performed cost-effectively while the walls, ceilings and floors were open and accessible during renovation.  Original construction documents were not available, requiring exploratory testing to expose the existing structure, determine existing conditions, and develop as-built drawings.
