Two CIM Group Projects Top Out in West Hollywood

Largo topped out at the 953 N. Sycamore project last week with the CIM Group in Los Angeles, CA. The development is two levels below grade and nine levels above with only the top three floors allocated to occupied space. The remaining levels of the 214,573gsf development are dedicated for parking a total of 418 cars. Designed by Lorcan O’Herlihy Architects and the BPA Group as structural engineers, the building twists away from the street as it moves up causing some of the cantilevered formwork and shoring to rest on the roof of the adjacent building.

Two blocks to the east along Romaine St., Parking Structure C Topped out for The Lot Studios around the same time. This eight level, long-span parking structure was completed in the design-build project delivery format. Largo Concrete was the general contractor self-performing the concrete place and finish and unit masonry scopes of work. The structure totals 140,790gsf and holds 398 total stalls with two elevators and two staircases. Working for the same CIM Group, the parking structure was designed by Parking Design Solutions and Ficcadenti Waggoner and Castle Structural Engineers and is scheduled to open early summer 2018.

ACI Charles Pankow Award for “Outstanding Achievement and Excellence in Concrete Construction” goes to the C3 Office & Parking Structure


Congratulations to the Culver City Creative (C3) team who helped us bring home the Charles Pankow, Jr. Award for “Outstanding Achievement and Excellence in Concrete Construction”! The annual award is given by the American Concrete Institute and recognizes outstanding and innovative use of concrete in construction.

About the Project:

Largo topped out at the Culver City Creative (C3) Office Tower and Parking Structure in January of 2017 with general contractor KPRS. Designed by Gensler and Saiful Bouquet, the commercial building stands seven levels tall with four mezzanine levels totaling 321,000gsf and is seeking a LEED Gold Certification. All the building concrete received an architectural finish and will remain exposed once complete. Typical levels are 14’ tall while decks with intermediate levels range from 22’ to 26’ between level seven and the roof. Six private balconies on the east and west sides of the building cantilever 11’6” out and are accessible through the large operable glass façade. Other unique structural elements include columns so large they are practically walls, aka ‘walumns’, and ring beams on the perimeter of the building at the mezzanine levels. The high-volume ceilings and available raw space allow 33,800sf decks to be easily expanded to 45,000sf with vertical and horizontal expansion options.

Access to the adjacent nine level, long-span parking structure is provided through two pedestrian bridges on the third and fifth levels allowing for private access to upper level offices. Designed by Parking Design Associates and Miyamoto International, this shear wall structure is two bays wide and will house 990 stalls across 326,741gsf. The pedestrian bridges connect to the structure on levels five and eight with the end-to-end helix structure providing 30 electric vehicle stalls and 50 bicycle spaces. The exterior features semi-opaque colored panels attached to the shear walls which refract sunlight back onto the structure creating an ever-changing façade throughout the day. All concrete on the parking structure remains exposed, including the elevator lobby. Largo poured 18,805CY of concrete in the office building and 10,874CY in the parking structure. The adjacent creative campus had to remain operational during construction and the biggest challenges came from protecting the existing parking structure and the cars inside of it.

Paseo Colorado Retrofit

Largo is currently working on the seismic retrofit of a two level below grade precast concrete parking structure at the Paseo Colorado development in Pasadena. Located along South Los Robles Avenue between Historic Route 66 (Colorado Blvd.) and Green Street, the upgraded structure will provide support for the new commercial and hospitality space to be constructed above.

Largo’s team is busy drilling and epoxying dowels to expand footings and enlarge columns and using cast-in-place concrete to construct shear walls. With hundreds of corbels to be installed, a custom steel form was created so the team could efficiently pour these support structures. Foam inserts in the deck are being used to lighten the load along Green Street instead of a thickened slab where the structure connects to street level. Placing embeds for structural steel and forming and pouring a new vehicular ramp are also included in Largo’s scope. The work includes additional utility rooms, new pedestrian access stairs and elevators, and modified exhaust, lighting and fire protection systems. Working with general contractor CW Driver, Gonzalez Goodale Architects and Englekirk Structural Engineers, Largo’s scope is scheduled to be complete in early 2018.

Britannia Cove Parking Structure Tops Out

Earlier this month, Largo topped out on the 9.5 level Britannia Cove at Oyster Point parking structure in South San Francisco. Located east of the 101 and north of Oyster Point Blvd., the structure features a total of 2,080 stalls spread across 721,250gsf. Designed by architect International Parking Design and structural engineer Culp & Tanner, this long-span, moment frame structure features a radius curve to match the Oyster Point Blvd. bridge over the 101. Working with general contractor Hathaway Dinwiddie, the structure will serve the new multi-tenant campus for life science and technology industries when complete in January 2018.

Creekside Parking Structure Near Completion

Just a couple miles east of our Northern California office, Largo recently completed the Creekside Parking Structure with South Bay Construction. Designed by Arc Tec, Inc. and Structural Engineers, Inc., the 8.5 level parking building will house 828 stalls across 277,832gsf. The structure will serve a new commercial office building and the existing Courtyard by Marriott, a cast-in-place, mid-rise building which Largo also constructed back in 2011. The south elevation is enclosed with CMU block and shotcrete was utilized for interior walls and parapets.

Culver City Creative Office & Parking Structure Topping Out

Largo topped out at the Culver City Creative (C3) Office Tower and Parking Structure earlier this month with general contractor KPRS. Designed by Gensler and Saiful Bouquet the commercial building stands seven levels tall with 4 mezzanine levels totaling 321,000gsf. All the building concrete received an architectural finish and will remain exposed once the building is complete. Some unique structural elements include columns so large they are practically walls, aka ‘walumns’ and ring beams on the perimeter of the building at the mezzanine levels.

Adjacent to the office building is the nine level, long-span parking structure which also topped out this month. Designed by Parking Design Associates and Miyamoto Int’l this shear wall structure is two bays wide and will house 990 stalls across 326,741gsf.

Chumash Casino Hotel & Casino Expansion and Design-Build Parking Structure

Largo Concrete started work on a 12 story hotel tower, 3 story casino expansion and 7-level parking structure at the Chumash Casino in Santa Ynez, CA. The new tower and casino total 354,663gsf and will add 217 rooms, 45,000sf of gaming floor, a food court and rooftop pool deck. This is the second hotel tower Largo has worked on for the Indian Gaming Community in the past 2 years having completed the hotel expansion at Harrah’s Rincon in Valley Center in 2013.

The parking structure addition is contracted under a Structural Design-Build project delivery format where Largo selected Culp & Tanner as the engineer. Once tied in to the existing structure an additional 480-stalls will be available to valet and self-parking users. Working closely with general contractor Tutor Perini Building Corp. and architect Delawie, Largo anticipates topping out the tower on 08/14/2015 and the parking structure on 09/01/2015 with the entire project scheduled to be complete in late 2016.

One of the major challenges was relocating 900CY of dirt over a creek to another location onsite, a feat that would have taken a 110 Ton Crane 9-days to complete. In order to enhance the schedule we rented an Acrow HS-20, 72,000lbs capacity, modular bridge and ran front-end-loaders across it to move the same amount of dirt in a single day!

Main Street Cupertino Parking Structure

Largo Concrete is currently working on the parking structure at the Main Street development in Cupertino. The long-span parking structure has a total of 8-levels, 2.5 of which are below grade, 1,414-stalls across 450,000gsf. The building utilizes a Shear Wall structural system designed by architects Kenneth Rodrigues Partners and International Parking Design with structural engineer Hohbach-Lewin. Largo is working closely with designers and the general contractor Southbay Construction to have concrete poured out by January 2015.

About Main Street

The Sand Hill Property Company is developing 17-acre site previously owned by Hewlett Packard located at the intersection of Stevens Creek Blvd. and Tantau Avenue for an estimated $330 million. When complete it Main Street will feature 130,000sf of retail, 260,000sf of commercial office space, 120 rental unit and a 180-roon hotel.

Poured Out at the Summerlin Parking Structures & Macy’s Tilt-Up Building

Largo Concrete poured the last elevated deck on two multi-level parking structures in Summerlin, NV today. Located immediately south of the Red Rock Resort and Casino both structures are on the west side of the development facing the 215 Beltway. Parking Structure #2, completed today, is 334,331gsf, 1-level below grade, 4-levels above with a total of 951-stalls, and PS3 is 186,233gsf, 3-levels above grade with 484 total stalls. Largo’s scope also included three pedestrian bridges connecting the parking structures to the retail center.

Largo also poured the foundations, tilt-up panels and slab on metal deck for the 2-story, 83,000gsf Macy’s department store adjacent to PS3. A pedestrian bridge connects PS3 to Macy’s second level. The 106-acre Shops at Summerlin development is scheduled to open during the Fall of 2014 and Largo worked with Whiting-Turner on the Macy’s building and VCC on the parking structure contracts.

Largo Tops Out at the Long Beach Courthouse

The Long Beach Courthouse, originally constructed in 1959, recently received a much needed upgrade in order to meet the region’s growing demands for state-of-the-art judicial facilities.

This upgrade by the California Judicial Council, includes the construction of a new 531,000 square-foot Courthouse, and is a financed through a unique Public-Private-Partnership between the Administrative Office of the Courts and Long Beach Judicial Partners, LLC.  This revolutionary development for social infrastructure utilizes the principles of Performance Based Infrastructure (PBI), a project delivery method which appoints a privately held firm to finance, design, build, operate and maintain the facility for a period of 35-years. Nestled comfortably on a 6 acre parcel on the corner of Magnolia and Broadway, the new “L”-shaped building will house 31 state-of-the-art courtrooms, administrative offices, and a secure courtyard.

At the peak of construction this project provided nearly 450 jobs for local contractors, subcontractors, and journeymen, of which 60 proudly represented the Largo team.  As a whole, Largo poured a total of 32,746 cubic yards of concrete between a concrete podium, slabs-on-metal-deck, a new transportation tower, and the retrofit of a nearby 900-stall parking structure.  For the mat foundation alone Largo poured nearly 12,000 cubic yards of concrete, requiring three boom-pumps pouring at a combined rate of nearly 3,000 CY per day for five days. In order to maintain the high volumes of ready-mix deliveries coming south on the 710 Freeway, the work started at 3:00AM to mitigate delays during the rush hour.

When asked about the challenges of this design-build project, Largo’s Project Manager Justin Green explains, “I enjoyed the complexity of the design-build process. The design was constantly changing which made it a challenge but I feel that it made me a better project manager.” Justin continues, “This was a great job for Largo to showcase how well we can execute high-profile and complex concrete projects on a design-build contract.”  Justin also credits his field superintendent and layout crew for their long hours and dedication in contributing to the successful completion of this complex project.

One major obstacle Largo faced was the 18-foot tall concrete basement walls, which needed to reach completion by a date that had been locked in for over 2-years in order to accommodate a delivery of structural steel to the jobsite. The design team elected to use cast-in-place walls instead of shot-crete, which put added pressure on the Largo team to form and place over 1,250 lineal feet of walls. Largo’s Project Executive Ted Rebelowski fondly recalls, “We hadn’t even finished pouring the entire mat foundation before erecting formwork for the basement walls!”

Clark Construction, the project’s design-build GC, had previously used Largo in 2009 on the successful University Gateway project in Los Angeles, and this added to heightened expectations for Largo’s team.  Largo has successfully delivered on those expectations, with construction moving smoothly towards finish despite the project’s complexity and fast-track delivery schedule.  Largo would also like to credit their reinforcing and excavation sub trades performed by the Commercial Metals Company (CMC) and Mike Zarp, Inc., respectively.

Largo Concrete placed and finished their last yard of concrete on June 28th of this year, and the new Courthouse is on schedule to open Fall 2013.
