Contending with ever-changing residential market wants and a fancy web site alongside Tempe City Lake, the staff establishing three multifamily towers at South Pier in Tempe is making speedy progress to take the concrete towers vertical. Starting from 21 to 23 tales tall, the high-rises generally known as Lot 6 make up the primary section of a $1.8-billion mixed-use growth that can finally embody a number of condo, apartment, lodge and workplace towers together with an leisure pier jutting out into the lake.
However that very same physique of water additionally added challenges to the muse work, which penetrates three ranges down into the Salt River’s alluvial soil and cobble. Within the early 2000s, some web site preparation and geotechnical work had been accomplished, however plans for the realm at the moment stalled because of the recession, and the positioning sat untouched, till now.
The present iteration of Lot 6, developed by Silverstein Properties and South Pier Tempe Holdings LLC, a subsidiary of McBride-Cohen Administration, locations it at a key spot on the south facet of Tempe City Lake, which is able to finally be surrounded by the Novus Innovation Hall, a 10-million-sq-ft mixed-use city area the place non-public companies and Arizona State College will collaborate on varied applied sciences.
Lot 6 architect Davis joined the venture in 2021 and inherited some early programmatic design work from one other agency that had been carried out when the venture was initiated by one other developer staff. “Our transient was actually to come back in at that time to reestablish the venture path by way of its program and high quality, do some worth engineering and convey it to an excellent design growth stage,” says Richard Drinkwater, principal and director of design for Davis.
Building started in August 2023 with contractor Clayco on the helm. The towers will embody 724 multifamily items, amenity areas and retail inside 1.2 million sq ft.

The towers are supported by 9-ft-thick mat foundations that sit under the three ranges of parking. “The water desk stage is correct round 30 ft, which is about the place our basement stage three is,” says Scott Thomas, senior venture supervisor with Clayco. “So with the mat basis set under that, we bumped into fairly a little bit of dewatering, and it appeared to worsen as we pushed the water towards the east. We spent about 45 to 60 days simply dewatering on the venture, pumping wherever from about 40,000 to 80,000 gallons of water a shift. It was fairly the method that we labored by means of to get that water out of right here, to have the ability to proceed to push the mat foundations and all the remainder of the footings.”
Davis had beforehand labored on one other growth to the west alongside a deeper a part of the lake, the place the water desk required a costlier bathtub-style basis.
For South Pier, Davis “wished to have a safeguard method to the residences as a result of there are three towers related by a typical parking storage under. So within the vertical culvert, there may be an early warning water sensor,” says Buck Yee, principal and venture architect with Davis.
Within the system, which might seemingly solely be wanted for a 1-in-50-year flood, stress launch valves within the backside stage of the storage can open and intentionally flood the basement when an excessive amount of hydrostatic stress builds up. The system, which offers ample discover for residents to maneuver their autos, eradicated the necessity for a way more costly and complicated bathtub-type design, Drinkwater says.

Subcontractor Suntec Concrete says it has been delivering full 14,000-sq-ft ground decks for each Towers 1 and a pair of each six days. The underside of the ground decks will probably be uncovered, requiring strict high quality management.
The staff goals to prime off Tower 1 in August at 230 ft. Tower 2 will comply with in September at 207 ft, after which crews from the primary tower will hop to the 226-ft-tall Tower 3 and end the concrete there by March. Placement sometimes happens in a single day to mitigate warmth, enhance security and maintain web site logistics on monitor, Thomas says. PK Associates carried out the structural engineering.

The venture incorporates prefabricated panels on the constructing pores and skin, manufactured in a 200,000-sq-ft store in Gilbert, Ariz., by MKB using between 80 and 100 employees. “This permits us to work on our pores and skin and incorporate all the weather of the constructing as we’re going vertical with our construction,” says Mike Broughton, senior venture supervisor with Clayco. Not solely does the prefabrication enhance sustainability by lowering building waste, but it surely “permits us to take care of security and total high quality, and likewise ensure we have now an excellent air/water barrier whereas doing that within the store.” Home windows are additionally being prefabricated in Mexico.
At peak, round 550 commerce employees will probably be on the web site. Thomas says Clayco has maintained an excellent security document with no recordables or lost-time incidents.
Each day foremen’s conferences and a morning stretch-and-flex with all web site employees fills everybody in on “what is occurring total on the positioning to be secure and perceive the place they must be and what might be taking place round them, even with different trades,” Thomas says.
Clayco offers coaching area for security and web site orientation in each Spanish and English concurrently.

Along with two full-time Clayco security personnel, the contractor additionally employs a full-time nurse to deal with minor scrapes or splinters. Clayco strategically locations cool-zone tents in key spots across the web site, together with on the elevated decks, in order that employees can go into an air-conditioned area to get a break from the Valley of the Solar’s intense warmth.
On the jobsite trailer advanced, the place most of the venture staff members are colocated, Clayco offers a site-specific orientation classroom with two sides arrange, one for coaching in Spanish and one in English.
“We are able to do round 40 people at a time. Up to now, we’ve oriented about 1,100 employees on web site. As trades come out and in, we guarantee that everyone seems to be conscious of the whole lot that’s taking place on web site,” Thomas says.

Maximizing Views
Clayco expects to wrap up Tower 1 in early 2026, with the opposite two towers following in mid-2026.
The excessive density on the web site offers design alternatives to maximise the distinctive setting of a “nice city enclave on the lake,” Drinkwater says. “We wished to play on that with the design of the constructing to create some actually great residential items by way of wonderful views, wonderful location, massive balconies and out of doors area that is known as a premium for residential items right here in Arizona.” Having all the parking under grade additionally helps create a pedestrian-centric panorama plan, designed by Dig Studio.
“One of many main differentiators for us right here is the huge amenity area that we have now amongst the three towers.”

“One of many main differentiators for us right here is the huge amenity area that we have now amongst the three towers,” says Lindsay Bruckal, Clayco venture government. Tower 1 homes a pool deck, health space, clubhouse and workspaces that emphasize the indoor-outdoor connection. Towers 2 and three share a good bigger amenity podium. Exterior areas and parks emphasize the connection to the lakefront.
Challenge house owners have been constantly centered on “making it a very distinctive and fascinating place to reside,” which has led to further upgrades to the amenity areas and inside design “to make them extra marketable and extra wanted for future tenants,” she says.
One such change lately relocated the health space from a double-height area subsequent to the amenity deck in Tower 2 to the bottom ground, so {that a} clubhouse might be added. Regardless of these flooring already being poured, Davis shortly pivoted with new drawings and located methods to configure the area to offer energy to exercise machines, Yee says.
Lot 6 and its individually developed neighbor Lot 5 will probably be joined by quite a few future mixed-use phases for the estimated $1.8-billion South Pier growth.

Davis continues to work with the builders on different phases, together with a conceptual design for an workplace constructing and one other multifamily tower immediately south of Pier 202 at Lot 1, which is a separate residential venture beneath building for a number of years by one other developer/builder. Davis additionally supplied a conceptual web site plan for the South Pier’s future leisure district, that includes a pier, pedestrian bridge and Ferris wheel.
Drinkwater hopes the design creates a “great setting the place folks will say, ‘Oh, I need to reside there!’”
