Roseville’s City Hall Earns USRC’s First Platinum Rating

Roseville’s city office building’s original design called for a steel structure with a plaster finish. However, the City selected the Precast Hybrid Moment Frame because it gave the architect flexibility in the design, met its tight delivery requirements and provided the City with reassurance that during an earthquake, critical operations and services would be housed in a resilient structure.

The PHMF structural system incorporates a high-performance precast hybrid moment-resisting frame that limits design level drifts to less than 1.25 percent. The system is designed to be self-centering after the seismic event eliminating residual drifts, limiting damage, and providing for reduced recovery time.

As the first ever building rated by the United States Resiliency Council (USRC), the Roseville City Hall Annex takes sustainable design to a new level. The fully precast concrete structure utilizes long-span  double-tees at each floor to maximize open space. Precast Hybrid Moment Frames utilized on the project are not only a high performing structural system but by featuring these as the exterior skin it results in an incredibly efficient design. The frames, which are self-righting, are designed to allow the building to be occupied immediately after a seismic event which was a major contributing factor to the building achieving a platinum rating,  highest rating possible from the U.S. Resiliency Council.

“The City of Roseville is extremely pleased with the project outcome. Publicly-funded projects of this size, scope and complexity are rarely, if ever, completed in the timeframe of 316 Vernon, due in significant part to the precast design and innovative just-in-time construction methods. Other added benefits from an operational perspective include: lower long-term maintenance costs, superior sound isolation / exterior noise suppression, and approximately 30% less energy consumption attributable to heating and cooling as a result of the building’s efficient thermal mass. As the owner and occupant, we couldn’t be happier.” – Mike Isom, City of Roseville

85 Bluxome Street

ZFA Engineering, Choosing a Resilient Design

The first building in San Francisco to receive a USRC rating is 85 Bluxome Street, a new five-story, 57,000 square-foot, Class A office building in the South of Market (SOMA) neighborhood. The steel-framed structure was awarded a USRC Gold Rating for achieving five stars for safety and four stars for both damage and recovery. Completed in 2016, the building was developed by Bluxome Partners, LLC, designed by RIM Architects and ZFA Structural Engineers, and constructed by BCCI Construction Company.

“The USRC rating at 85 Bluxome is a long-awaited first step in increasing transparency so that people can be aware of the very real risks that are present in this region.” – Mark Moore, Executive Principal at ZFA Structural Engineers

With San Francisco office space hitting record high prices, maximizing leasable area is one of the top priorities of commercial developers after the safety and comfort of occupants. At 85 Bluxome Street, ZFA Structural Engineers, a founding member of the USRC, helped achieve both by using a high-performing proprietary SidePlate moment frame system to provide a stiffer-than-required structural frame that reduced building drift and allowed the footprint of the building to extend as close as possible to property lines. With careful accounting, the return on investment for this strategy was clear; the added square footage was of far greater value than the cost of the additional structural steel used to achieve it.

In addition to maximizing leasable space, the structural system’s high stiffness provides superior performance that exceeds current building code earthquake requirements, which contributed to the USRC Gold rating. Additional attention to detailing of stairs and anchorage of mechanical equipment means not only that the building was rated in the top category for safety (five stars), but that it is expected to fully recover from a major earthquake in less than one week. This building is a great example of the synergy that can exist when multiple goals are aligned and everyone – owners, tenants, and communities – wins.

The Society Hotel in Portland, Oregon Among First to Receive USRC Ratings

This four-story, 1881 building was seismically retrofitted in 2014. The Chinatown hotel was originally a refuge for sailors on ports-of-call and later part of the Portland Hospital. The seismic retrofit was mostly paid for by the tax credit the developer received for the historic preservation of the hotel.

“The Society Hotel owners and staff are honored to be one of the first four buildings in Portland to receive the U.S. Resiliency Council’s Silver Rating. It was a challenge to seismically upgrade the building while simultaneously completing a Historic Preservation through the National Parks Service, but we were committed to making the building as safe as possible for our guests and staff while also preserving this historic nineteenth century Portland landmark. We’re thrilled to give it new life in the twenty-first century and beyond.” – Gabe Genauer, The Society Hotel

Seismically upgraded mixed use space thrives in Portland’s industrial district

This four-story building in the Central Eastside Industrial District was built in 1908, and seismically retrofitted in 2013. The historic mixed-use building serves creative and professional office users, and two up-scale restaurants. The original user of the Building was Oliver Chilled Plow Works, a farm equipment manufacturer, and later numerous light industrial uses.

San Gabriel Shops

San Gabriel, CA

IDS Group Making Buildings Safer in Southern California

Shop 1841 is a two-story retail building located in the city of San Gabriel in Southern California. It has about 13,500 sq. ft of retail area including the partial second floor that covers about 1/3 of the building footprint.  The original construction of the building goes back to the 1940’s or 50’s and consists of a long span wood truss roof supported by reinforced concrete walls in the retail areas. The building had an addition in the 1970’s where the 2-story portions with wood floors and reinforced CMU walls were added. Most recently, the building was partially remodeled and seismically retrofitted in 2010. The limited retrofit consists of steel moment frames added at the open store front as well as several plywood shear walls added throughout the building. Struts and ties at the ceiling and roof levels have also been provided as part of the 2010 seismic retrofit. The building site is located near a major fault and is classified as highly seismic.

IDS utilized relevant provisions of ASCE 41-13 to evaluate this building. A Tier-1 screening according to Chapter 4 of ASCE 41-13 was performed. The performance level was chosen as Life Safety (LS) according to ASCE41-13 Table 2-1. Apparently due to the seismic upgrade of the building in 2010, no structural deficiencies were detected. A few nonstructural deficiencies related to piping, equipment, and glazing were found. The SP3 seismic performance prediction program by Haselton Baker Risk Groups was used to determine the building’s USRC Ratig. The building obtained 4 stars, 4 stars, and 3 stars for the three dimensions of Safety, Damage, and Recovery respectively. Considering the age of the building and the fact that virtually all types of construction materials have been used in it, namely steel, reinforced concrete, masonry and wood, it’s Silver (4-4-3) Seismic Rating is very impressive.

Much of the credit goes to the owner, Mr. Paul Jenkins of the Star Building Group, whose approach to the mitigation of seismic risk is an outgrowth of his philosophy that earthquakes ought to be viewed and dealt with as a natural part of the local environment. Just like we prepare and protect ourselves and our places of residence/work/school from the effects of hot or cold weather or rain or the strong sun, so should we prepare for earthquakes which are bound to occur in this region without warning.
