Montgomery Park Plaza Office Building

Wednesday, May 11th, 2011

Erickson Structural performed a structural evaluation of the existing concrete floor slab of the Montgomery Park Plaza Office Building, located in Portland, Oregon, to determine its ability to support the additional weight of a topping/leveling slab added to two office spaces within the building.  Additionally, a multiple number of holes were cored through the existing slab to allow for new plumbing as part of the remodel.

Utilizing information gleaned from the original construction drawings and non-destructive testing of the slab to determine the presence of reinforcing steel, Erickson Structural was able to analyze the slab and recommend appropriate strengthening measures to compensate for the added weight and new holes.

 

CCFD 6 Fire Station

Monday, November 22nd, 2010

A workout room on the second floor of the Clark County Fire District 6 (CCFD 6) Station No. 1 had perceived “bounciness” in the floor framing, especially when weights were moved or dropped on the floor.  Erickson Structural personnel were retained to conduct an evaluation of the floor framing below the workout room to assess the structural adequacy of the existing floor framing.  Original construction documents were reviewed and the station was visited to observe existing structural conditions.  Schematic remediation schemes for the identified deficiencies were provided.

Ka’ahumanu Congregational Church

Tuesday, October 19th, 2010

Registered as a historical landmark, the original Ka’ahumanu Congregational Church was built in 1876, and is still in use today.  The building is experiencing severe structural wood termite decay, the steeple is leaning, and the floor framing and canopy are deteriorating.  Erickson Structural was retained to diagnose the structural consequences of the wood decay, perform a structural evaluation of the building and propose structural remediation options.  Where possible, remediation of seismic deficiencies identified during the evaluation will be included in the upcoming remediation project.

Kona Pacific Condominiums

Tuesday, May 11th, 2010

The Kona Pacific Condominiums, located in Kailua-Kona, Hawaii, are a mid-rise condominium complex, comprised of six buildings, constructed circa 1979.  In 2006, investigative studies were commissioned to evaluate moisture intrusion and resulting structural distress to concrete masonry unit (CMU) walls and concrete columns, walls and slabs.  The resulting reports identified multiple locations of moisture intrusion and subsequent damage to CMU and concrete structural elements.  The reports recommend several remediation measures, including the removal and replacement of the existing water-proofing system, and the repair of spalled and damaged concrete and CMU structural elements.  Kona Pacific Condominium Association of Apartment Owners (AOAO) intended to implement these, and other, recommendations by undertaking a construction repair project.  Erickson Structural personnel were retainted to assist with this objective.

Erickson Structural personnel performed an initial structural condition assessment, intended to clearly identify structural repair needs, scope and costs, prior to procuring construction services.  This approach allowed the Kona Pacific AOAO to better plan and manage the repair scope, process and associated costs.

 

Old Wailuku Post Office

Wednesday, January 27th, 2010

Erickson Structural was retained to perform a structural assessment of the former Wailuku Post Office, located in Wailuku, Hawaii, to determine what structural implications might be associated with the conversion of the building to office use by the County of Maui.  Erickson Structural was also asked to comment upon the physical condition of the building and to provide initial opinions regarding the structural feasibility of the proposed conversion.  The initial assessment revealed cracked exterior concrete panels, corroded reinforcing steel and minor water infiltration.  However, the building was deemed structurally sound and a viable candidate for remediation.
