Lara Lane Apartments

Monday, February 27th, 2012

Erickson Structural provided structural engineering services for the design of structural bracing of the cantilevered timber piling below the buildings at the Lara Lane Apartments, located in Portland, Oregon.

Wimbledon Square Apartments

Tuesday, May 10th, 2011

Several apartment units on the first and second floors of the Wimbledon Square Apartments, located in Portland, Oregon, were entirely destroyed as the result of a fire.  Damages included the structural roof framing, supporting wall framing, floor framing, architectural finishes, fire rated assemblies and appliances.  However, less than 50% of the building area had been damaged by the fire, therefore a building-wide mandatory seismic upgrade was not required by the City of Portland.  Damaged framing or components of the lateral force-resisting system  were designed to comply with current building codes.  Erickson Structural personnel performed site visits to observe and document the structural damage and then provided structural engineering design for the recommended repairs of the fire-damaged portions of the structure.

SE Hawthorne Fire Damage

Tuesday, May 10th, 2011

Erickson Structural personnel were retained to assess the extent of fire damage to this three-tenant commercial building, and to provide structural remediation design services.  Though the majority of the fire damage was contained to one of the tenant spaces, damage did extend to the roof structure above the adjacent tenant spaces.  Erickson Structural personnel successfully designed the required structural repairs in a manner that minimized disturbance to adjacent tenant spaces.  Though damaged structural components were replaced with code-compliant repairs, a full-building seismic upgrade was avoided based upon Erickson Structural personnel’ assessment of the extent of the fire damage and coordination with the City of Portland.

 

Sinnott Building

Tuesday, May 10th, 2011

This historical three-story, unreinforced masonry building, located in Portland, Oregon, was declared a “dangerous building” by the City of Portland Bureau of Development Services.  Nine specific responsibilities were identified by the City of Portland that the building owner was required to address, two of which prompted the involvement of a structural engineer.   Erickson Structural personnel were retained to address the deficiencies associated with portions of the parapet braces and cornices.  Erickson Structural personnel performed site visits to observe existing conditions during the construction of the repairs and developed construction documents depicting the temporary structural remediation of the parapet braces and cornices.

 

Consolidated Supply

Tuesday, May 10th, 2011

After water had chronically infiltrated the Consolidated Supply building’s exterior envelope and created substantial structural damage, Erickson Structural personnel were retained to evaluate and repair the resulting structural damage.  To maintain ongoing business operations within the building, the building’s exterior skin was removed and evaluated a section at a time, and damaged structural framing was repaired utilizing techniques developed in consultation with the general contractor.  An addition to the building was also designed and constructed during this project.

Erickson Structural personnel worked closely with the repair contractor to coordinate construction in phases, thus avoiding having the entire building exterior open at once, and ensuring ongoing business operations.

Hale Pau Hana Condominiums

Tuesday, December 21st, 2010

Multiple holes were cored through the structural floor slab during a renovation of an upper floor unit of the Hale Pau Hana Condominiums, located in Kihei, Hawaii.  Erickson Structural was retained to review these conditions and render an opinion regarding the structural integrity of the concrete slab.  Erickson Structural reviewed the original construction drawings, coordinated with a testing firm to conduct a scan of the reinforcing steel and performed engineering analyses using the data gathered during the scan.  The results of the analysis showed that the slab was structurally deficient.  Erickson Structural then designed fiber reinforced polymer (FRP) strengthening measures to compensate for the loss of strength attributed to the slab penetrations.  Erickson Structural’s design allowed for minimal impact upon the existing building aesthetics.  The design also allowed for repairs to be completed in a rapid manner, an important factor to the owners of the affected units who had rental guests scheduled to arrive soon after the completion of the renovation project.  Erickson Structural remained active on the project during the construction phase to respond to contractor questions and unforeseen conditions, allowing the project to move forward with minimal delays.

Beverly Court Apartments

Monday, November 22nd, 2010

After portions of brick veneer fell from the exterior of the of the Beverly Court Apartment building, located in Vancouver, Washington, the City of Vancouver was forced to designate the structure as a dangerous building.  When other structural engineers failed to prepare plausible explanations for the cause of this failure, Erickson Structural personnel were retained to address the problem.  After conducting a thorough investigation, Erickson Structural personnel designed the rehabilitation scheme for the veneer remediation.
