The Transbay Joint Powers Authority (TJPA) board of directors has called for a complete structural evaluation of the Pelli Clarke Pelli–designed Transbay Transit Center in San Francisco after installation crews discovered failing steel structural beams there in September. Now, over a month later, the transit center has been closed for longer than it was open as crews work to discover what went wrong. This week, representatives from TJPA, structural engineer Thornton Tomasetti, contractor Webcor/Obayashi Joint Venture, steel fabricator Herrick Corporation, and material supplier ArcelorMittal are all convening in New York to study material samples that were removed from the failing girders for further analysis. Engineering News Record reported that crews discovered bottom-flange cracks near the midpoint of one of the eight-foot-deep shop-welded girders. A second, more serious fracture was discovered running the entirety of a flange on the second beam. The two beams run parallel to one another over an 80-foot span running over Fremont Street. At a recent meeting, the TJPA board called for a complete structural evaluation of the 1.2 million-square-foot transit center in order to inspire public confidence in the structure’s safety and design. Ultimately, however, TJPA officials currently have no idea why the beams failed and because the fissures were discovered by accident, it is unknown if other areas are prone to fail, as well. At the meeting, one TJPA board member asked, “Was the engineering done right?" before adding, “We need assurance." The structural review team will now work to understand what happened before making design recommendations for how to fix the problem. Once a consensus is reached regarding on the cause of the girder failures, engineers will design a permanent fix that will also be peer reviewed to ensure its safety, Engineering News Record reported. TJPA projects that repairs will begin in December and take several months to complete.

New York–based architects Perkins Eastman and engineers Arup have unveiled the latest batch of renderings for San Francisco’s Harvey Milk Plaza. The updated designs were submitted to city agencies this week in an effort to begin the formal approval process for the renovations envisioned for the plaza and its associated Muni subway station. The extensive renovations come as the city works to perform required Americans with Disabilities Act (ADA) upgrades for both facilities, including the addition of an elevator that will connect the street level to the subway platform. Backers for the project also seek to boost the plaza’s function as a memorial to Harvey Milk, San Francisco’s first openly gay elected official, and to create a new gateway into the city’s Castro neighborhood. Perkins Eastman was selected in 2016 as part of an international design competition held by Friends of Harvey Milk Plaza (FHMP), the volunteer group with business connections in the neighborhood. The latest renderings for Harvey Milk Plaza come after a previously-released iteration of the design was met with community opposition. Perkins Eastman revised the plans following four community workshops over the summer. The initial designs featured red paving and a uni-directional “stramp” (stair-ramp) that crossed the site going toward the west to create an elevated community amphitheater with the subway entrance located below. The new plans have flipped the arrangement by rotating the amphitheater and subway entrance 180 degrees so that they are located at the easternmost corner of the site, where it is expected that foot traffic would be greatest. The center of the plaza is now marked by a new elevator with the western edge of the plaza populated by low-slung benches and a grove of trees. The plaza bearing Milk’s name was planned before his death and was not named in his honor until 1985—Milk was assassinated in 1978— and according to FHMP, “the public has longed to see [the plaza] transformed into a place that captures [Milk’s] spirit; a place that embodies [Milk’s] passion to bring people together and see that all are treated with dignity and given voice at the tables of influence.” The plaza redesign is more-or-less the product of community input, Hoodline reports, a delicate dance the designers and organizers have played with local residents as they seek to win on-the-street approval for the project. The designs, however, are relatively unloved by San Francisco Chronicle urbanism critic John King, who has lamented that the plaza would weaken the vitality of the district’s street life by pulling pedestrians away from its key attractions. King added that the proposal’s function as a true memorial to Milk’s legacy could better be suited by other means, as well. King said:
If the desire is to celebrate Milk’s life and legacy, it might be easier to freshen up the current plaza and create an ongoing fund for its maintenance. Then, install plaques or informative artwork along the bridge-like walkway to Collingwood Street, a path that has serenity despite its surroundings.The design for the proposal is by no means finalized, however. As the bid makes its way through the approval process, changes and new approaches are sure to be recommended. A timeline for final approval and completion of the plaza has not been announced.
A few years ago, it would have been impossible to predict that Casper, a startup with a single product, would launch an entire industry of mattresses ordered sight unseen online and become a global sleep powerhouse. It was inevitable that the company would outgrow the house where it was brainstorming the next breakthrough. That its new prototyping space, Casper Labs, is now based in a former industrial laundry service in San Francisco’s Mission District is an apt metaphor for the city’s tech-driven transformation. The company tapped hometown design firm Spiegel Aihara Workshop (SAW), led by principals Dan Spiegel and Megumi Aihara, to convert the warehouse space into its R&D headquarters. SAW’s design for the 11,500-square-foot, two-story office attests to the demands of an industrial workspace where mattresses and heavy prototypes are tested and hauled around. But it is also filled with nods to the company’s association with pillowy softness. The architects achieved this with an unlikely material—corrugated steel in a range of perforated profiles that are meticulously layered to read like fabric. “With a rough industrial material, it was about finding ways to give it a textile nature,” explained principal Dan Spiegel. “Once we had that in play, we could experiment with transparency.” On the ground floor, the white, powder-coated steel unravels at different heights, wrapping the metal shop, a testing lab, and a wood shop with rounded corners that reference the company’s iconic mattress. The opaque surface fades to a translucent screen as it rises above eye level. In other areas, the steel walls mask storage and service areas through a one-way transparency, admitting natural light without allowing views in. This play between opacity and transparency is further demonstrated in the entry area, where the Casper logo glows behind a corrugated surface. All it takes is the flick of a light switch for the letters, along with all the other signage in the space, to disappear. “We like the mystery that set up,” said Spiegel. “Even though there’s a lot of what ended up being opaque surfaces, you could begin to imagine that all of them had something going on just behind that skin.” With much of the program left open-ended for collaboration, the main work areas feature doorless openings lined in oiled steel plate that echo the steel columns that came with the space. The custom entryway desk continues the motif of rounded corners and transparency but incorporates a warm wood framing that takes its cue from the wood joists in the ceiling, with the whole piece sliding easily out of the way to access storage beyond it. Another design touch that highlights the tension between heavy and light, the industrial and the domestic, hovers above the common area for all-hands meetings. There, SAW’s custom lighting fixture floats like a geometric cloud composed of 117 Casper pillowcases folded and twisted onto a welded, tubed steel frame. It is details like these that elevate the lab beyond a typical industrial facility and gesture at the space’s raison d’être: a good night’s sleep.
A report issued by the Applied Technology Council, a group of independent engineers organized at the behest of the city of San Francisco, has concluded that building codes in the city are woefully inadequate with regard to seismic safety. According to the report, while structural codes in the city are written in order to ensure that buildings will not collapse in an earthquake, they pay little attention to whether the impacted structures will continue to be suitable for occupancy following a disaster. Specifically, the panel has called for inspecting and retrofitting existing tall buildings while also suggesting that stronger structural regulations are needed for new towers, The New York Times reports. In addition, the panel has recommended that structures be designed with a greater degree of rigidity and that infrastructural elements like plumbing, elevators, and electrical and information technology systems be built to a higher quality. The expert panel was organized during the tenure of late San Francisco mayor Ed Lee in response to the slow-moving catastrophe occurring at the Millennium Tower site in the city's central business district. There, the Handel Architects–designed tower has been listing to one side. Overall, the tower 58-story tower has sunk over 18 inches with no sign of stopping. The uneven distribution of the tower's settling has created potential fire hazards as the cladding on one side has begun to pull apart. The city even threatened to "yellow tag" the structure after a window on the 36th floor cracked over Labor Day weekend. The report's urgency has been underscored by recent structural failures at the Salesforce Transit Center, where a pair of structural steel beams supporting the terminal's rooftop park have cracked. The transit center has remained closed for the two weeks since and no projected opening date has been announced. Authorities are currently inspecting the structure and beginning to repair the fractured beams. The officials behind the new report have created a database of tall buildings that lists which structural systems were used for every tower. The list is part of an effort to spread awareness of the structurally-deficient welded steel moment-frame structural technique deployed in high-rises between 1960 and 1994. Structures built using this system are thought to be at risk of failure during the strongest possible earthquakes. The database lists 39 towers, including William Pereira's TransAmerica Pyramid and John Portman's Embarcadero Center, among others. The full report, titled Tall Buildings Safety Strategy, can be found here.
Long considered an environmental steward and an urban booster, outgoing California governor Jerry Brown has signed a series of pro-density and housing-friendly bills into law as the final legislative session of his last term as governor draws to a close. Among the issues supported by the spate of bills are: efforts to build more densely around transit stations in the San Francisco Bay Area; a desire to enshrine Obama-era federal fair housing guidelines into California law; and plans to force wealthy municipalities to build their fair share of affordable housing. A list of some of the significant legislative gains signed into law by Governor Brown follows: AB 2923 Assembly Bill 2923 settles a long-running battle to give the Bay Area Rapid Transit (BART) authority a greater degree of control over the land that it owns surrounding its transit stops across the Bay Area region. The land in question is currently subjected to many of the strict density limits imposed by surrounding housing-adverse communities. The enaction of the bill will allow for up to 20,000 new housing units—35 percent of which would be affordable housing—to be built on the roughly 250 acres the authority owns by 2040. In a statement, BART general manager Grace Crunican celebrated the victory by sounding a conciliatory tone. She said, “Although AB2923 directs BART to adopt new transit-oriented development (TOD) zoning standards for each BART station, I want to assure community leaders and residents that BART is committed to continuing our collaborative approach. We have found that working closely with neighborhoods and local elected officials to consider community needs is not only respectful, it's the most efficient way to get the job done.” The measure gives local municipalities two years to update their zoning plans to accommodate the new housing or risk losing all control over BART-associated projects currently under their jurisdiction. AB 686 Assembly Bill 686 would require any housing- and community development–focused public agency to administer its programs and activities in a manner that supports the Affirmatively Further Fair Housing (AFFH) efforts of the 1968 Fair Housing Act. The bill represents an effort to enshrine those protections—as well as Obama-era fair housing programs—into California law amid a federal restructuring of fair housing priorities under the current administration. Housing and Urban Development Secretary Ben Carson has referred to AFFH unironically as a “social-engineering scheme” despite the fact that AFFH efforts serve to counter the long-standing legacy of federally-enacted and enforced racial segregation and redlining in American neighborhoods. Secretary Carson is currently working to “reinterpret” AFFH goals, which many racial equity activists have interpreted as an effort to dismantle the guidelines entirely. AB 1771 Assembly Bill 1771 aims to reform California’s Regional Housing Need Allocation (RHNA) law in order to make regional housing planning more data-driven and transparent by ensuring that high-income, job-rich cities plan and zone for affordable housing. The bill represents an effort to force wealthy cities like Beverly Hills and those surrounding San Fransico to plan for additional affordable housing so that existing low-income communities are not solely saddled with the burden of producing more housing. There is an emerging trend showing that these low-income communities have seen concentrated growth in both new market rate and affordable housing, a phenomenon that has fueled displacement and gentrification. AB 1771 aims for an initial and partial fix by beginning to hold wealthy areas responsible for producing their fair share of affordable housing. SB828 Last but not least, State Bill 828 would reform the methodology California uses when setting local housing goals for the RHNA mentioned above. Moving forward, the state will use several data-based metrics, including the percentage of renter households that are overcrowded and current vacancy rates, to calculate each municipality’s new RHNA goals. The newly-enacted laws follow several years’ worth of legislative gains for housing advocates in the state. However, the efforts have yet to meaningfully reduce the number of rent-burdened households in the state and have had an even smaller impact on racial segregation or access to homeownership for low-income households. These issues are expected to take center stage for California’s next governor when they take office in 2019 following the November election.
A second cracked steel structural beam was discovered at the Salesforce Transit Center in San Francisco Wednesday during an overnight examination, The San Francisco Chronicle reports. AN reported the initial cracked beam Tuesday afternoon. The Chronicle reports that the initial fissure discovered in a steel structural beam supporting the transit center’s 5.4-acre, PWP Landscape Architecture–designed park measures roughly 2-1/2 feet long by four inches deep and runs across the bottom of a 60-foot-long spanning element located above Fremont Street between Mission and Howard Streets on the transit center’s east side. The second damaged steel beam that was discovered runs parallel to that element and features a crack that is "slightly smaller," according to the report. As a result of the escalating situation, the transit center will remain closed at least through October 5 as crews work to investigate other elements of the structure, according to the Transbay Joint Powers Authority (TJPA), the entity that oversees the transit center and managed its construction. Pelli Clarke Pelli Architects designed the terminal as well as the Salesforce Tower located next door. During a news conference Wednesday afternoon, Mark Zabaneh, executive director of the TJPA, said, “We will not open the transit center or Fremont Street until we are certain the issue is 100 percent rectified.” Officials at TJPA are worried the structural elements might fail and are therefore operating with a high degree of caution with regards to keeping the transit center closed. The steel beams in question were fabricated in Stockton, California, by Herrick Corp. as part of a $189-million contract struck between Skanska USA Civil West of New York and TJPA. TJPA authorities are inspecting the structure with the project contractors—Webcor and Obayashi entered into a joint venture for the job—and structural engineering firm Thornton Tomasetti, which was the engineer of record for the structure and also performed construction work on the building. Those authorities also plan to bring in independent engineers to reassess the facility’s design. AN will continue to report on this story as it develops.
The recently-opened, $2.2-billion Pelli Clarke Pelli Architects–designed Salesforce Transit Center in San Francisco was closed unexpectedly this afternoon after a major crack was discovered in a steel beam that supports the structure's 5.4-acre roof garden. The fissure is located on the third level bus deck on the eastern side of the transit center. Bus operations that serve the terminal were rerouted back to the so-called “Temporary Terminal,” a makeshift bus depot at Howard and Main Streets that was used while the transit center was under construction over the last eight years. Mohammed Nuru, chairman of the Transbay Joint Powers Authority, the entity that oversaw construction of the transit center, told The San Francisco Chronicle, "I'm told there's a problem with a steel beam," without elaborating further. NBC Bay Area reports that Mark Zabaneh, executive director of the Transbay Joint Powers Authority issued the following statement:
“The safety of everyone who visits the Salesforce Transit Center is our obligation and highest priority. While this appears to be a localized issue and we have no information that suggests it is widespread, it is our duty to confirm this before we allow public access to the facility."Thornton Tomasetti, the engineer-of-record for the project, did not immediately respond to requests for comments for this story. PWP Landscape Architecture was the landscape architect for the project. It is unclear if the issue at hand is in any way related to recent reports of the pothole-like depressions that have been spotted along the walkway of the rooftop garden in recent days. The nearby Millennium Tower designed by Handel Architects has also suffered mysterious structural anomalies since it opened in 2016. A recent report indicates that the structure was leaning as much as 18 inches to the west. AN will continue to monitor the situation and report updates as news on the transit center takes shape. Update 10:30am PST: The streets around the transit center remain closed this morning as crews work to inspect the structure for further anomalies. Reports indicate that the cracked support member was last inspected a year ago and that it is made from American-produced steel. Salesforce Transit Center officials have planned a news conference for noon Pacific time to provide an update on the investigation.
The saga of San Francisco’s slipping Millennium Tower continues, as a window on the 36th floor of the Handel Architects–designed residential tower cracked over Labor Day weekend. Engineers were dispatched by building management to examine the crack from the exterior but in a streak of continuing bad luck, the drone lost its GPS connection, careened into the neighboring Salesforce Tower, and crashed to the ground. If building managers are unable to determine why the glass cracked by the end of this week, San Francisco's Department of Building Inspection has threatened to "yellow tag" the tower, restricting access until the area is proven safe. The 58-story, 645-foot-tall tower has already tilted 18 inches west towards Mission Street since its completion in 2009, which has unleashed a string of problems for residents and the building’s owners. Condo owners have written off their units as having zero value, cracks have appeared in the basement, tenants have reported awful smells in their units, and the building’s movement may have created a fire safety hazard by causing a void to form between the building’s structure and curtain wall. The problem is that the 60-to-90-foot-long friction piles underpinning the building were driven into sandy soils rather than bedrock at 200 feet down. While no concrete explanation has been given for continued sinkage, developer Millennium Partners has blamed construction of the neighboring Salesforce Tower for pumping out too much groundwater and causing the soil to settle. While the engineering firm Allana Buick & Bers collects more information on whether the crack was an isolated incident or a symptom of the tower’s 18-inch tilt, a new, cheaper alternative has been proposed to halt up the building’s continued slippage. It’s expected that the tower will sink another inch per year if nothing is done, but engineer Ron Hamburger, hired by Millennium Partners, recently proposed an expedited fix. As NBC Bay Area reports, the $400-to-500 million cost to drill 150 new piles through the building’s foundation has caused a massive legal fight between the tower’s homeowners’ association and developers. Hamburger’s solution to install 52 piles–26 on either side of the corner of the block at Mission Street and Fremont–would stop the building from tilting further and would only cost $80 million. However, as NBC notes, the tower’s seismic performance may have already been compromised by its movement and propping up the worst-affected area might not stop the building from sinking or leaning elsewhere. No solution has been accepted by all of the parties involved in the legal battle as of yet, but AN will follow up if plans to stabilize the building move forward. More information on why the window broke should be forthcoming; the Department Of Building Inspection has ordered Millennium management to fix the window-washing rig on the roof to allow in-person inspection of the window by 3:00 p.m. this Friday. Engineers must also conduct a survey of all of the tower's windows, other units, and potential damage to the facade by Friday afternoon, and install an overhead safety barrier to prevent debris from falling on the sidewalk by later today if they wish to avoid having the building yellow tagged. A full forensic report is expected to be submitted to the city as well.
The Pelli Clarke Pelli Architects (PCPA)–designed Salesforce Transit Center and its 5.4-acre rooftop park in San Francisco are now officially open to the public. Decades in the making, the opening of the $2.1 billion, 1.2 million-square-foot terminal this August capped off eight years of construction and followed the completion of the 1,070-foot-tall Salesforce Tower next door in February. Taken together, the three elements—terminal, tower, and park—represent the beginning of a new era that, according to the planners behind the transformative project, is driven by a focus on public space and public transit. Dubbed the “Grand Central Terminal of the West” by its civic boosters, the new multimodal transit center is meant to be the crown jewel of a new high-rise, mixed-use, transit-oriented neighborhood anchored by the multifunctional rooftop park and capped off by the tower. The arrangement is one of the many by-products of a far-reaching district plan crafted to embrace the terminal and reshape the city’s skyline. Designed as a massive, skylit, indoor-outdoor living room sandwiched between transit and a park, the terminal is geared for public use first and foremost. Inside its cavernous halls, terrazzo-based flooring by Julie Chang, a light installation by artist Jenny Holzer, and a fountain by James Carpenter enliven the grand and formal spaces designed by PCPA. A total of 3,992 perforated white aluminum panels—designed in collaboration with British mathematician Roger Penrose—wrap the terminal, skinning a bulbous, undulating object that sneakily cuts across the neighborhood. The lacey wrapper brings light into a second-story bus terminal and helps to dematerialize the massive complex. This visual transparency becomes physical porosity along the ground floor, where the multiblock building spans over city streets, weaving through the commercial district with its 85,349 square feet of retail space. Fred Clarke, a founding partner at PCPA, described the transformative project and the whirlwind of construction it has engendered as “transit-oriented development at a scale we haven’t seen before” in the United States. Clarke observed, “Our car-oriented society typically works against this building type, so we feel like we are cutting new ground here.” The expression is quite literal in this case, as the complex begins 125 feet below ground, where a five-block-long concrete box acts as a massive foundation for the complex containing below-grade ticketing, retail, and concourse levels. For seismic resiliency, the 1,000-foot-long terminal is designed as three structurally isolated sections connected by a pair of 2-foot-wide expansion joints that allow each piece to move independently. Thornton Tomasetti is the engineer-of-record for the project and served as a sustainability consultant for the Salesforce Tower project, as well. The also building comes outfitted with one of the largest geothermal installations in the world, according to the architect. It is a design that not only allows for impressive energy efficiency, but also reduces the need for the clunky air handling units on the roof that would typically accompany conventional HVAC systems. Situated 70 feet above grade, the terminal is topped by a new public park designed in partnership with PWP Landscape Architecture. Flower beds and tree pits of varying depths meander around the rooftop, where the verdant park is home to 100 trees, a 1,000-seat amphitheater, three sculptural lanterns, a playground, and a 1,000-foot-long fountain by artist Ned Kahn, among other elements. The stormwater-retention-focused park is also sculpted by artificial mounds concealing elevator overrides and mechanical equipment. Standing beside all of this is the Salesforce Tower, a tapered pinnacle defined by rounded corners, “classical proportions,” and a large crown that lights up with a large-format LED video artwork by artist Jim Campbell. The 61-story tower connects directly to the park and touches the ground with a light, open lobby that is meant to enliven the district, “in a simple, elegant way,” according to Clarke.
Chicago-based Studio Gang has unveiled new renderings for a 40-story housing tower slated for San Francisco’s Transbay neighborhood. Designs for the so-called Mira Tower are inspired by the city’s classic bay windows, which the firm has reinterpreted, stacked, and arrayed around the edges of the faceted tower. In a statement supporting the project, Studio Gang principal Jeanne Gang said, "Reinterpreting the classic bay windows of San Francisco, our design amplifies the dynamic quality of the neighborhood.” The project is among several high-rise towers coming to the neighborhood that is taking shape around the recently-opened Salesforce Terminal and Salesforce Tower complex. The project renderings, first published by Dezeen, show a twisting column of projecting window bays that stagger across each facade of the tower. The window walls are interspersed with glazed balconies along certain areas and are framed by what appears to be white metal panel cladding. Each major surface of the building undulates in a wave-like fashion, with projecting bays oriented generally toward specific vistas. Despite the undulating walls, a crisp corner line is carried up the height of the tower at some of the building’s corners. Gang added, “Spiraling all the way up this 400-foot tower, bay windows create unique spaces in every residence that offer fresh air, expansive views, and changing qualities of light throughout the day." Studio Gang has been steadily increasing the number of projects it is undertaking in California over the last few years. The firm is currently working on a campus expansion for the California College of the Arts campus in San Francisco and a new housing complex that will update the Charles Moore-designed Kresge College at the University of California, Santa Cruz. The firm also recently unveiled plans for a curvy apartment tower that will be located in Los Angeles’s Chinatown neighborhood. Mira Tower is currently under construction with sales efforts to begin in earnest this fall. Tishman Speyer is the developer behind the project.
Forbes recently reported on the controversy surrounding a suicide barrier that will be installed on the Golden Gate Bridge in San Francisco, California. The barrier is projected to cost $211 million of public money, which some say is too high, while others say that the landmark's iconic appearance should not be changed. The barrier will consist of a net extending 20 feet horizontally out from the bridge's deck, held up by steel members painted the same color as the bridge's main structure. The net will be about 20 feet below the bridge deck's top surface, so anyone falling onto it would still sustain injuries, but much less severe ones than they would receive from a fall to the water below. The Golden Gate Bridge Highway and Transportation District, the authority responsible for overseeing the barrier's construction, refers to the net as a "deterrent," and says that similar structures have been successful in hindering suicides related to other structures around the world. According to Forbes, the bridge is the second most popular suicide destination in the world, and the LA Times has reported that dozens of people die from jumping off the structure every year. Forbes also reported that the $211 million bill is almost three times the original $76 million estimated price for the project. The barrier should be in place in 2021.
With buildings responsible for about 47 percent of electricity usage in the U.S., making buildings more efficient should be a top priority in combatting climate change. New York City has already pledged to retrofit its older buildings and slash CO2 emissions by 80 percent by 2050, but with the withdrawal of the U.S. from the Paris Climate Agreement, such action has been left to cities and states to undertake voluntarily. At the Global Climate Action Summit in San Francisco this September, businesses, investors, and local and state leaders from across the country will convene to discuss ways to decarbonize the economy and reach a carbon neutral U.S. by 2050. The AIA has announced that it will be sending a delegation headed by President Carl Elefante, FAIA, to represent architects at the summit and come back with a set of scalable best design practices. The AIA members attending will be part of the organization’s sustainability-oriented Committee on the Environment (COTE) and other climate change-related groups. The AIA will also be sponsoring two public events during the summit: Carbon Smart Building Day on September 11 and Climate Heritage Mobilization on September 12 and 13. The summit is meant to in part build momentum for COP24 in December, the 24th Conference of the Parties to the United Nations Framework Convention on Climate Change. Still, even if radical decarbonization guidelines are agreed upon at the summit and adopted by the AIA and business leaders in attendance, such a shift likely wouldn’t be enough to reach the Intergovernmental Panel on Climate Change (IPCC)’s target of limiting global temperature increases to 2 degrees Celcius. The Paris Agreement and temperature targets are only reachable if the world were to produce negative emissions and sequester CO2 on a massive scale, a technology that’s still several years away. Still, the AIA has pledged to continue pursuing its sustainability and environmental health goals, as seen in its recent call for a blanket ban on asbestos in building products after the fracas last week.
