St. Teresa of Calcutta Tops Out in San Diego

The St. Teresa’s of Calcutta affordable housing project topped out on the corner of 14th & Commercial in downtown San Diego this month. Largo worked with Level 10 Construction on the 15 level high-rise and three level podium development which holds a total of 407 units, 270 of which will be used specifically to address homelessness. The 18′ high ground level will house commercial and retail space with a fitness area, community room, management offices, and courtyard on the second level. The superstructure is made up of 17,563CY of concrete creating 328,514sf which was poured over the course of nine months.

Limited laydown area and the adjacent Covid-19 vaccination site added to the logistical challenges of the downtown environment. A Peri core-wall system which sat on embeds and did not rely on trailer panels for support was used to form the core. This allowed our crews to close the entire core the day before the deck was complete and pour both vertical and horizontal elements at the same time. During the typical levels our teams were able to pour an 18,000sf deck every week to meet the aggressive schedule.

Named in honor of Mother Teresa the development’s two main partners are the San Diego Housing Commission (SDHC) and Father Joe’s Villages, Chelsea Investment Corporation. The development will remain affordable for 55-years for San Diegans with low-income or who are experiencing homelessness. Designed by Joseph Wong Design Associates and BWE Structural Engineers, the development is scheduled to be open during the third quarter of 2021.

Prometheus Residential Podiums Top Out in the Bay Area

Two residential podium projects topped out in Mountain View, CA this month with the Prometheus Real Estate Development Group. The Tillery is located along Villa Street and The Hadley is two miles south along E. Evelyn Avenue., with both properties backing up to the Central Expressway.

The Tillery features two levels of below grade parking and a podium deck at street level for a total of 256,856gsf. The parking area holds 318 stalls and the four levels of wood frame above hold a total of 226 units. Largo is working with general contractor SBI Builders, BDE Architecture and Nelson Structural Engineers who plan to have the building open during the third quarter of 2021.

The Hadley Apartments for general contractor Palisade Builders have a similar configuration with two levels of below grade parking with a podium deck and wood framed residential above with a total of over 410,000sf. When complete the complex willhold 679 parking stalls and 471 residential units. The project is expected to be complete during the forth quarter of 2021 with BDE as lead architect and Nelson Structural Engineers.

Frost Center Tops Out at Cal Poly San Luis Obispo

Largo recently topped out at the Frost Center for Research and Innovation at Cal Poly San Luis Obispo. The project 102,000gsf building five levels above grade and will house the  Colleges of Science and Mathematics, Agriculture Food & Environmental Sciences and Liberal Arts. The building will house configurable classrooms and cutting-edge laboratory space dedicated to enhancing the university’s educational philosophy of “learn-by-doing.” The facility also includes a computer lab, three conference rooms and 43 faculty offices. The complex is designed to achieve LEED Gold® certification and incorporates measures to maximize passive cooling and heating, utilize natural ventilation in the faculty offices, consume 30% less potable water, and exceed current Title 24 standards by 20%.

The new building is located north of the Baker Science building between Poly View Dr. and Perimeter Rd. The façade features extensive masonry work taking cues from the adjacent science and liberal arts buildings. Interior vertical concrete was constructed using both shotcrete and cast-in-place methods wherein 2,000 cubic yards of self-consolidating concrete was used for all exposed columns and shear walls. From the first floor of the atrium brick, concrete and wood finishes are work together as the central design theme.

Working with general contractor Gilbane, ZGF Architects, LLP, and John A. Martin & Associates structural engineers, the building is scheduled to be open for the Fall 2021 semester.

APEX Tops Out in San Diego

Perched along Towne Centre Drive in San Diego, CA, the new APEX commercial office building has impressive views of Sorrento Valley to the east. Largo topped out with general contractor Rudolf & Sletten on the 345,000gsf structure which has been leased to Apple. Designed by Perkins & Will architects and Coffman Structural Engineers the building has two levels of below grade parking with five levels of above grade including the roof.

Designers attempted to integrate modern architecture with the surrounding biodiversity to enhance the user well-being. Exposed concrete walls blend with extensive glass and steel accents on the exterior façade. The concrete roof deck is also exposed and cantilevers toward the canyon sheltering the outdoor terrace on level four. There is a total of 37,000sf of exterior architectural concrete on the project which includes feature walls, columns, and sloped soffits. All exposed elements were designed with dimensioned seam plywood layout for a consistent special finish. A computer generated solar study was used to determine the most effective placement of sunshade elements to maximize daylight and visual connections to the environment.

Amenities include a fitness center, an outdoor workout area, volleyball court and game area with horseshoe and corn-hole space. A cafe, amphitheater and flexible workspaces round out the amenities and blend with the architectural features to produce a unique creative space. In total Largo pour over 27,000CY of concrete over the 10.5 month schedule.

Hawthorne Elementary Tops Out and 701 Magnolia Ramps Up

The Hawthorne Elementary School topped out this month in Dallas, TX earlier this month. The low-rise project is two levels above grade totaling 81,500gsf with a 6′ tall mini basement or crawl space below. The first elevated deck above the void is cast-in-place with level two being a combination of concrete and slab-on-metal-deck. Largo is also doing the site concrete scope for the facility scheduled to open during the Fall of 2021. This is our first project with Imperial Construction, Glen Partners Architects and Alpha Consulting Engineers and we look forward to many more in the future.

701 West Magnolia
Forty miles to the west in the Near Southside district of Fort Worth, Largo is beginning construction on the 701 W Magnolia development with general contractor Muckleroy & Falls. The four level creative office building has retail on the ground floor which runs along an open-air mall. On the opposite side of the mall features historic buildings dating back 100-years . A three level parking structure is also included in the development designed by VLK Architects and L.A. Fuess Partners structural engineers. Largo is scheduled to be poured out by October 2021.

San Mateo County Parking Structure Tops Out

Largo Concrete recently topped out at the San Mateo County Parking Structure 2 project with general contractor Truebeck Construction. Located on the southwest corner of Veteran Blvd. and Brewster Ave., the structure will serve employees and visitors of the government services facility in Redwood City. Watry Design acted as the architect and structural engineer on the project and designed the structure to accommodate future parking demand.

The long-span building is designed with a shear wall structural frame and holds 1,022 stall across seven above grade levels. The structure features an exterior half-circle helix ramp 89’6″ in diameter with a slope of 6 degrees. The ramp has 22′ drive isles which are wide enough for two vehicles to pass side-by-side. In addition to reducing the amount of vehicular traffic on the parking decks the express ramp preserves the full footprint of the ground level for alternative uses should parking demand decrease in the future. Level one is designed with 14’11” floor-to-floor heights in order to accommodate human uses.

On long-span parking structure with a park-on-ramp traffic flow crews and equipment can easily move up the building as construction progresses. With the exterior ramp construction following a couple levels behind the decks crews were forced to use a manlift and additional hoisting of material from grade level.

The 345,100gsf structure has a metal screen façade allowing for natural ventilation and 61 electric vehicle charging stations on all levels. A photovoltaic array on the roof deck will offset energy usage from the charging stations. The building is expected to be completed during the first quarter of 2021.

345 4th Street Tops Out

The eight level commercial office development on 345 4th Street topped out in San Francisco this month with GC Stoer Construction. The building will be occupied by WeWork, one of the leading space-as-a-service platforms providing flexible real estate options to businesses of all sizes. Designed by Stanton Architecture and DCI Engineers, the building provides 50,000sf of office space and retail storefront at street level. Located in the South of Market (SoMa) District, the downtown skyline will be visible to the north from the vegetated rooftop terrace.

By far the most striking feature of the building is the 77 ft. tall, 28 ft. wide board-formed concrete wall on the West elevation.

Illuminated inset numbers which bare the namesake of the building stand 9′ tall and run vertically down the wall with a smooth concrete finish. The wall was accomplished using shotcrete applied from the interior of the structure onto the boards and around the foam number inserts.

Linea Los Angeles Wins ACI Award for Decorative Uses of Concrete

The American Concrete Institute (ACI) gave the “Decorative Uses of Concrete Construction” award to the Linea Apartments in Los Angeles, CA. Click here to view a list of all the projects which received recognition at this years virtual event and check out the Linea project video below:

The Linea mid-rise luxury apartment complex is centrally located along Sepulveda Blvd. between Pico and Exposition in West Los Angeles. The 545,000gsf development features two levels of below grade parking, three levels of retail and commercial space starting at street level, and residential units from the podium deck up. A total of 911 parking stalls are provided for the 566 market rate and 66 affordable housing units. Residential space is spread out across one ten level and three five level structures rising from the podium. The boomerang shaped nine level structure is located toward the back of the podium and has post-tensioned slabs and a concrete moment frame with both upturned and downturned beams. The five level buildings are light gauge metal stud structures facing Sepulveda Blvd.

The 125,000sf of slab on grade area starts two levels below grade with 1,550CY of shotcrete applied to the perimeter and radial ramp walls of the subterranean parking levels. Due to rebar congestion shotcrete crews utilized a “hybrid method” to place the pilasters in the perimeter basement walls. This is accomplished by forming the pilaster with Stayform then pouring and vibrating readymix into the form without the air component. The Stayform is then removed and the surface is pneumatically applied and finished in the traditional shotcrete fashion. 14,000sf of 22’ tall decks are also featured in the podium structure where teams used Titan XL 625 posts for shoring. During the height of construction in the J-shaped shaped podium Largo had two boom pumps onsite utilizing four masts.

The podium plaza level features a landscaped courtyard with two pools and communal outdoor dining and recreation areas. The modern outdoor living space is decorated with 10,000sf of architectural board-formed concrete parapet walls and planters. The exposed concrete look is carried on to the courtyard roof deck on level ten of the cast-in-place structure, where more concrete benches and board-formed planters can be found lining another pool, a spa, daybeds and cabanas.

Designed by Van Tilburg, Banvard & Soderbergh Architects with Englekirk providing the structural engineering, the development opened during the summer of 2020. The penthouse currently rents for over $15,000/month with impressive views of the I-10 and I-405 interchange. Overall, Largo Concrete placed 53,200CY of concrete over 11 months. 73 elevated deck pours were accomplished over a 9.25-month duration averaging a pour ever 2.7 working days.

Ivy Station Wins ACI Award for Outstanding Performance in Design and Engineering

The American Concrete Institute (ACI) recently awarded the Ivy Station project the award for Outstanding Performance in Design and Engineering. Click here to view a list of all the projects which received recognition this year and check out the Ivy Station project video below:

The new development sits adjacent to the Culver / Venice Metro Line Station in Culver City, CA along Venice and Jefferson Blvd. This city-block-wide transit-oriented development is a true mixed-use project with a commercial office space, hospitality rooms and residential units with a retail plaza at street level. Each component sits atop a three level below grade, 607,000sf parking podium housing 1,538 stalls, 300 of which are dedicated to Metro riders.

The versatility of the podium is also depicted with three different building types rising from the 218,000sf plaza level lined with space for retail and food stores. The 148-room hotel utilizes structural steel while the 200 residential units are spread across wood frame. Both components are five stories tall sitting atop an elevated deck of concrete while the entire commercial building is cast-in-place concrete.

Over 23,600CY was placed for the 236,700sf mat foundation ranging from 17” to 60” thick three levels below the street. Largo utilized their own powerful City Pumps to hose the readymix hundreds of feet from the street down to the jobsite. Nearly 3,000CY of shotcrete walls were pneumatically placed around the perimeter of the basement parking levels. Interior structural walls up to 3’ thick enclose staircases and radial ramps giving pedestrians and vehicles access to the below grade parking.

At the plaza level, structural columns switch from rectangular to circular which juxtapose the angular shaped decks. Typical levels have a 13’8” floor-to-floor height with the first and fifth levels at 15’. The concrete columns, interior walls and soffits remain exposed throughout the commercial building to usher views outward to the street and plaza with a grand entrance off Venice reaching 28’5” in height. Largo worked with general contractor Bernards, KFA architects and Englekirk structure engineers to place 81,500CY of concrete over 14 months.

Natiivo Tower Tops Out at 48 East Avenue

Largo Concrete topped out at the Natiivo tower in downtown Austin, TX earlier this month. Located at the edge of the rapidly growing Rainey Street District, the 442,668gsf building is 33 levels all above grade. The first nine levels of the building are dedicated to parking with 24 levels of residential above holding 248 units.

All units come fully furnished with hotel licensing and can be offered as short-term rentals with building management providing hotel-like services and amenities. In addition to on-site concierge, housekeeping and laundry services the building also features a 18,000sf open air terrace on the 10th floor and a rooftop pool with cabanas and fireplace seating areas.

In total Largo poured 20,000CY of concrete over the course of 15 months with 130,000 manhours. The building is designed by STG Design and Cardno Haynes Whaley structural engineers and general contractor AECOM Hunt expect to have the project complete during the summer of 2021.
