During a test run last Wednesday, giant ballerinas could be seen dancing across a beige background over 1,000 feet in the air. The tower’s signature piece, Day for Night, will start by showing the colors of that night’s sunset, followed by constellations against the night sky until the sun rises again. While the top nine floors of the Salesforce Tower are unoccupied and were used to push the building into “tallest in San Francisco” territory, only the upper six floors will be used to stage Campbell’s installation. The remaining three will hold the required equipment and will be bathed in a strong light to form a base for the animation above. While the punctured panels could theoretically show any images, Campbell swears that his work won’t be used for advertisements or to mark holidays. San Francisco Chronicle. The developers, designers, and engineers behind Salesforce Tower will be presenting on their work at the next Facades+ conference in San Francisco, taking place on June 7.

The bullet-shaped office tower, a centerpiece of Salesforce’s campus-like headquarters, opened its doors to employees on January 8th. Clad in glass and horizontal bands of metal accents that serve as solar shades, the building curves at the corners and tapers to a point as it rises. Pelli Clarke Pelli describes the design as aping the “simple, timeless form of the obelisk”. The tower has been LEED-Platinum Certified, and Salesforce claims that they’ve implemented an “innovative water recycling system” throughout. The façade continues past the top floor to create an ethereal crown, using perforated aluminum panels, that somewhat lessens the topper’s impact. A nine-story vertical facet has been slotted inside of the building’s topper, and the empty space within will be used to potentially project lights, patterns and photos across the tower’s crown; artist Jim Campbell has proposed using LED lights to display ever-changing pieces of art. Connected at the base of the tower is the Salesforce Transit Center, a new transit hub that will hold 11 transit systems when it’s complete later this year, also designed by Pelli Clarke Pelli. The Transit Center takes a markedly different approach from its neighbor, making use of a billowing wall of perforated aluminum panels to gently wrap the station’s upper floors. Supported by V-shaped columns, the station is centered around a massive “Light Column,” a sculptural skylight that grows all the way from the train platforms below to the transit center’s roof. The Light Column also serves to open up the main hall of the hub by creating a 118-foot-tall roof. A 5.4-acre rooftop park will top off the transit center, complete with running tracks, cafes, a 1,000-seat amphitheater, children’s playground, and fully accessible grasslands. Pelli Clarke Pelli claims that the ecology of the park will mirror the surrounding Bay Area, and feature everything from oak trees to a wetland marsh. AN will have an in-depth review of Salesforce Tower in the coming months, but in the meantime, Salesforce has posted a preview of the building’s interiors here.
According to recent findings, San Francisco’s sinking condo tower just got a little bit more down to earth.
The 58-story Millennium Tower, designed by Handel Architects, has sunk nearly 17 inches since its opening in 2009. Last summer, controversy enveloped the failing monolith when the settling came to light, as residents posted videos online of objects rolling across their floors to demonstrate just how slanted the 419-unit building had become.
Recently, engineers with Arup—employed to work on the currently under-construction Salesforce Tower designed by Pelli Clarke Pelli Architects next door—inspected the Millennium Tower’s rooftop height and found that the tower had sunk an additional 2 ½ inches beyond the initial 14 ½–inch drop recorded last year. Increasingly, the tower is tilting precariously toward the Salesforce Tower, as the muddy and sandy soils beneath it give way. It is built on a foundation of concrete friction piles, driven between 60 and 90 feet into the soil, that do not rest on bedrock. The method is employed by several other developments in the area, though the type of settling occurring at the Millennium Tower has not been seen in any of those projects.
Troublingly, the tower is not only sinking, but it is sinking unevenly, resulting in a measurable slant to the 645-foot-tall complex. As the muddy and sandy soils beneath it give way, it continues to tilt precariously toward the Salesforce Tower. As of 2016, according to court documents, the tower exhibited a 2-inch westward tilt at the base and listed a whopping 10 inches at its top. Recent projections put the potential maximum drift at 10 inches every two years unless something is done to rectify the issue.
As can be expected, the structural deficiencies have resulted in a flurry of lawsuits, including one from the building’s homeowners’ association. The association is seeking to force Millennium Partners, developers and owners of the tower, to perform $150 million worth of foundation upgrades that would add 150 new end-bearing piles in an effort to rest the building on bedrock.
“This accelerated movement highlights the need to retrofit the foundation as soon as possible,” Daniel Petrocelli, attorney for the Millennium Tower homeowners’ association told NBC Bay Area. “The Millennium Tower Association will request an early trial in its ongoing lawsuit to hold the responsible parties accountable.”
A five-acre redevelopment of Boston’s Bulfinch Triangle will replace a much-maligned concrete garage
“This part of the city is not as dependent on automobiles as everybody imagined it would be,” said Kishore Varanasi, principal and director of urban design at Boston-based CBT Architects. The firm is working with the HYM Investment Group to redevelop the area. Fellow CBT principal David Nagahiro added that today approximately 1,200 cars use the garage on a daily basis.
Echoing their 1960s predecessors, CBT and HYM have big, transit-oriented plans for the site. De-emphasizing the automobile, the $2 billion “Bulfinch Crossing” master plan involves the creation of a new public square and pedestrian promenade linking Rose Fitzgerald Kennedy Greenway and the Market District along Congress Street through to Canal Street. Space to store 850 bicycles (a city requirement) will be included as will a Hubway station for Boston’s bike-sharing program and direct connections to Zipcar, the MBTA bus service, the Green and Orange subway lines, and the North Station commuter rail service.
CBT’s $2 billion master plan was approved in 2013, and a year ago the city gave the green light to two of the tallest structures in the development: New Haven firm Pelli Clarke Pelli’s One Congress office tower at 528 feet and a 480-foot residential tower from CBT Architects.
All in all, Bulfinch Crossing will see 812 residential units, 1.2 million square feet of offices, a 200-key hotel, and 85,000 square feet of street-level retail and restaurant space added to the area; 1,150 parking spaces will also be available. The mixed-use development will be the first to include significant housing in the urban renewal district and demonstrates a refresh of downtown typologies by creating slender towers with a reduced footprint.
“Much of the design challenge has been to design the space so that it has eight different desire lines—both visual and physical—that run through the site,” said Varanasi. In plan, Bulfinch Crossing doesn’t look like a typical plot of grid-divided land primed for development. Instead, a variety of shapes work to facilitate these desire lines and natural circulation through the site.
The scheme will be completed in phases. “Nobody needed convincing that this garage has to go away,” said Nagahiro, who added that despite this sentiment, the garage couldn’t simply be knocked down. Even though the facility is only at half-capacity, its daily use is a valuable source of income to the city and, as a result, will be taken down incrementally to sustain city revenue. However, the garage will remain open for business throughout the redevelopment.
Reconfiguring the garage for operation during construction is due to be completed this spring. Construction of Pelli Clarke Pelli’s tower isslated to begin as early as 2018 and the site pad for CBT's 480-foot residential tower is currently under construction and is scheduled for completion in summer 2020. Further construction deadlines are yet to be finalized because they are predominantly market-driven, however, Varanasi speculated that the garage should be in its final stage by 2023.

In what seems to be an unintentional release of information, the floor count for two of Chicago’s most anticipated towers was recently listed online. On an Epstein webpage, which has since been removed, the number of floors for Wolf Point East and Wolf Point South was listed as 64 stories and 70 stories, respectively. The page also described Wolf Point South as a mix of office and residential, information that seems to put to rest the rumor that the tower might include a hotel. Both towers were designed by Pelli Clarke Pelli Architects, and their heights, one of which may reach over 900 feet, have been the topic of much discussion. Wolf Point East is expected to break ground in 2017.
