Miro Towers Become the Tallest Buildings in San Jose

The Miro Towers became San Jose’s tallest structures this month when Largo poured level 29 at 291′ above street level! Located on the north side of E. Santa Clara Avenue between Fourth and Fifth, the buildings are across the street from City Hall which used to be the city’s second tallest structure. Miro will feature a total of 630 two and three bedroom units and 633 parking spaces.

Stressing Procedure

Transfer girders utilize four rows of post-tensioned cables which are progressively stressed throughout construction. The girders are located on level five above grade and are up to 72” wide by 64” deep! The additional rows of PT cables are spaced 6” apart and lay below a row of tendons which are stressed after placing level five. Upon completion of level ten the bottommost row is stressed, then the second from the bottom row is tensioned at level 15, ending at level 25.

Steinberg Hart Architects, DCI Structural Engineers, and general contractor Suffolk Construction are on schedule to have the Miro towers open early 2021.

Two Good to be True: Twin Towers in Century City and San Jose Reach for the Stars

Century Plaza, Century City, CA

Checking in first at the New Century Plaza development in Century Plaza where we recently poured level 33. Designed by Pei Cobb Freed & Partners, Harley Ellis Devereaux Architects and Englekirk Structural Engineers, the towers will stand 46 levels above grade and house 290 luxury residential units when complete. The towers are located behind the historic Century Plaza Hotel which is currently being retrofitted to include 63 condominium units in addition to 349 hospitality suites.

The project began with the installation of over 25,000CY of mat foundations. Since then, the development has progressed through 4 levels of below grade parking, back-of-house, retail and commercial space at pavillion street level, and into the typical tower levels. The tower decks are shaped like reuleaux triangles in an effort to pay homage to the iconic Century Plaza Office Towers on the opposite side of Avenue of the Stars. The edges of the triangular decks are lined with scalloped-shape balconies designed to mimic the façade of the exisiting hotel. Working with general contractor Webcor Builders, the concrete is expected to top out during the Fall of 2020 . Once complete, Largo will have placed over 150,000CY of concrete!

330 miles to the north, in the heart of Silicon Valley, Largo continues to work on two of the city’s tallest buildings. The Miro development features two residential high-rise towers located on East Santa Clara Street, across from San Jose City Hall. The project is laid out on a 1.4 acre site and consist of three levels below grade and 28 levels above. The 630 units sit atop seven levels of parking with a total of 633 stalls.

Transfer girders utilize four rows of post-tensioned cables which are progressively stressed throughout construction. The girders are located on level five above grade and are up to 64”deep by 72” wide! The additional rows of PT cables are spaced 6” apart and lay below a row of tendons which are stressed after placing level five. Upon completion of level ten the bottommost row is stressed, then the second from the bottom row is tensioned at level 15 and so on. The project is designed by Steinberg Architects and DCI Structural Engineers, general contractor Suffolk Construction anticipates concrete topping out early summer.

UCLA Margo Leavin Art Studio Wins Charles Pankow Award

Largo Concrete worked with Abbott Construction on the UCLA Warner Graduate Art Studio Project in Culver City, CA.

The overall project consisted of a 21,200sf renovation of the Graduate Art Studios existing building and a 26,800sf, L-shaped addition to the facility. Design by architecture firm Johnston Marklee, the building is organized in the fashion of a ‘community’ with small blocks of private studios in a cul-de-sac setting adjacent to communal, plaza like facilities connected by pathways akin to city streets. Specialized lab space for woodworking and ceramics are also included in the facility which is designed to be adaptable to accommodate future new technologies and working methods. The Margo Leavin Art Studio project anticipates a LEED Gold Certification.

The construction of this building utilized several different concrete assemblies to support the building and achieve the natural concrete look. This was especially important to designers and the University to integrate the facility into the former industrial zone know as the Hayden Tract. The exterior walls were designed as concrete tilt-up panels with 2′-0″ “pillows” or half-circles on the exterior face. Special single-use form liners were designed and fabricated out of state to achieve the “pillow” shapes. Cast-in-place stitch columns were used to connect the tilt panels at each grid line. The stitch columns also used the “pillow-shaped” form liner but were exceptionally challenging because they were poured full-height (28′-10″) between the panels and had to line up perfectly with no gaps or visible seams. Largo Concrete’s in-house engineering team designed custom falsework to support lintel panels which would eventually be suspended 15’-0” in the air. These panels also feature the “pillowed” exterior finish and are unsupported from below as they span the openings to the building.

The interior frame of the building consists of cast-in-place walls, columns and ring beams: all exposed with an “as-cast” finish. Shotcrete walls and beams were installed against the existing building walls on two sides to connect the new construction to the existing building. As was the case with the exterior finish, no sacking or other cosmetic enhancements were allowed on the interior as well. The buildings roof is designed as a grid of vaults with curved glulam beams covered by roofing membrane, curved polycarbonate or nothing at all to allow for natural ventilation in certain spaces.

Limited access to the building pad because of the existing structure made it difficult to form, place and hoist the tilt-up panels. The time frame to complete all of the building concrete was 8 months. Despite these challenges the concrete scope of work was completed in eight months with zero safety incidents over 29,213 hours. Some of the potential hazards that were endured included 30’-0” shotcrete walls and beams, 30’-0” shear walls and columns, 30’-0” tilt-up panels and hoisting the panels with a high voltage wire running along one side of the jobsite.

Building Under the Disney Height Cone at the Anaheim Resort District

Westin Resort
Largo recently topped out on the last of three hospitality projects in the Anaheim Entertainment District. The Westin Anaheim Resort is located on the south side of Katella Avenue from Disneyland next to the Convention Center. The development features 634 rooms spread across 9 above grade levels with 31,200sf of retail and restaurant space on grade. When the development opens during the summer of 2020 it will be Anaheim’s second, non-Disney four-diamond resort. Largo worked with general contractor KCS West, architect  Harley Eliis Devereaux and structural engineer Englekirk.

The Disney Height Cone
The Westin’s proximity to the Disneyland Resort meant the design had to conform with what local developers refer to as the “Disney Cone”. This height restriction on buildings surrounding the park allows visitors to be totally
immersed in the Disney experience with limited views of anything non-Disney . This effort began back in the 1960’s with a strategically placed landscaped berm surrounding the park and has evolved into a city mandate. Currently, the ‘cone’ limits heights of buildings immediately surround the park to 75′ gradually increasing to 240′ a half-mile away from the resort. 

JW Marriott
Just one mile east of the Westin along South Clementine Street Largo poured the concrete at the 466 room JW Marriott hotel with general contractor W.E. O’Neil. Construction on this 13 level structure began during the spring of 2018 with Largo pouring three large mat foundations totaling 5,796CY over the course of 2 weeks. Designed by Morris Architects and structural engineer Walter P. Moore, this 488,692gsf development is scheduled to open during the spring of 2020. When it is complete this development will be the first non-Disney four diamond resort in Anaheim.

Cambria Suites
One block further east on Katella Avenue, Largo worked with Nexus Construction and davisReed on the Cambria Suites project. Largo topped out on the one level below grade and 13 levels above structure in January of 2019. In addition to the 352 rooms the resort will feature a 30,000sf water park, outdoor movie viewing area and 15,000sf of restaurant and retail space.

Anaheim Resort District Projects
Largo Concrete has a rich history in the Anaheim Resort District which includes the following projects: Holiday Inn, Staybridge Suites, Worldmark, Disney Grand Californian Expansion, Little Mermaid, Frontierland Expansion, Great Wolf Hotel and Resort and the Anaheim Convention Center Expansion.
