While we have built our reputation on concrete work for large-sized and notable projects, we have also been a part of smaller jobs that are just as important to those who benefit. A commuter bike connection was sorely needed to link two major roads in Novato, CA. to give bike riders a safe alternative to riding along the side of a very busy freeway.

Opened in Dec of 2011, the beautiful Enfrente Pathway is a 0.6-mile, multi-use trail that is completely separated from cars and provides a critical link to central and south Novato. The project was made possible by a grant of $1.95 million from the federal government and is a part of the Non-Motorized Transportation Pilot Program for Marin County. The contractor was Ghilotti Construction and the engineer was SOHA Engineers.

Conco’s expert concrete services were used to help with the construction of the path. The project required installation of soil nails used to retain the hillside. Sculpted shotcrete was applied as a finish over the soil nail walls. Once the walls were constructed, the area was graded in preparation for the paving of the concrete pathway. A concrete retaining wall was constructed at one end of the project and a concrete barrier was built at the other end. For added safety, fencing was also put up along the path.

Now that the connector is complete and offers a safer route, the hope is that more cyclists will opt to ride to work, which will help to reduce traffic and create less greenhouse gas emissions. Conco is pleased to have been a part of a project that enhances the lives of those in the Novato area and helps to keep cyclists and pedestrians safe.

Conco is one of the leading concrete contractors in San Francisco offering a range of innovative, quality services. We have been honored to work on many high-profile projects and were recently awarded the concrete package for the San Francisco 49ers Stadium. Our concrete services include commercial, educational, parking and other construction development as well as public works projects.

Conco was brought in on another project to help provide solutions that would reduce costs and save time. Devon Construction, owner and contractor of the new complex, Lawson Lane Commons in Santa Clara, CA. contracted Conco for concrete services to build a new parking structure.

The 4-level parking garage will accommodate 2,948 vehicle spaces for the new development that when completely done will consist of 638,958 sq. feet of office space and an amenities facility. The project is being done in two stages with Phase I opened in July, 2012 with two 5-story office buildings and the 2-story amenities building.

Phase II of the Commons will be an addition of two 6-story office buildings and the completion of the campus environment. The high efficiency buildings are expected to see up to a 30% savings in utilities from the Santa Clara power company. This development among several others being done throughout the city is adding to the construction boom under the shadow of the massive on-going 49ers Stadium project.

Conco’s solution to building the parking structure cost-effectively and quickly was to use shotcrete as opposed to cast-in-place concrete. The structure for the Commons has shear walls spanning 310 lineal feet and 40 feet high. The foundations for the walls were poured, and then three more separate shotcrete pours were done over the course of 25 business days using a total of 390 cubic yards of concrete.

Our design team and estimators projected that using shotcrete saved 24% over what the more traditional approach of cast-in-place walls would have cost. We saved time and also saved labor cost by eliminating several of the days it could have taken to complete the project. Furthermore, the shotcrete walls have the same structural characteristics as traditional cast-in-place walls.

Conco’s team of professional concrete contractors in the Portland area brings the highest level of integrity and principles to each project from pre-construction to finish. With the rapidly growing construction market, Conco is taking an active role in the Portland area with our expansion of high-quality commercial concrete services.

Shotcrete is the method of applying concrete pneumatically through a high pressure nozzle. It can save both time and money over typical cast-in-place concrete since Shotcrete walls are constructed faster as they need less forming and use less material. Without tie holes (that need to be filled, leaving visible blemishes), it can be an aesthetically appealing alternative.

An exciting new field is developing that takes shotcrete to the next level. Talented shotcrete craftsmen are using sculpted shotcrete as a canvas to create artistic walls that have all of the same structural integrity of a standard shotcrete wall.

The application of sculpted shotcrete is only limited by the imagination. It is a great way to either highlight a structure or blend it into the local landscape with its ability to easily apply color, stains, and textures. Great looking projects are being done with shotcrete that is stained and textured to naturalize an area or to turn plain walls into beautiful murals.

Retaining walls are a great example of where shotcrete’s adaptability and wide range of finished surfaces are designing architectural solutions for stabilizing areas. Rock sculpting and texturing is used to take a functional project and turn it into something that is very artistic and attractive.

When the City of Burien, WA, which sits below the Cascade Mountain range, needed to build a parking garage, they didn’t want a structure made up of stark concrete walls. Their goal was to turn the building into a piece of art that highlighted the city’s most visible landmark, Mount Rainier, and the surrounding mountain ranges. Conco worked to create sculpted shotcrete murals that depicted views of the Cascades, Olympics, and Mount Rainier on all four sides of the building.

For over 50 years, Conco has been providing premium concrete services and is one of the most trusted concrete contractors in Seattle. We partner with clients on every project from the pre-construction stage right through to final completion to maximize efficiency and ensure goals and budgets are met. Our concrete services include commercial, educational, parking and other construction development as well as public works projects.

Coming Out of the Ground in Seattle’s Theatre District

The Holland Partner Group has come out of the ground with a new 40-story apartment building adjacent to the historic Paramount Theatre. This project, with its close proximity to Rapid Ride Transit and Seattle’s retail core, positions itself in the middle of the vibrant downtown. Upon completion this project will consist of 325 apartments, 276 parking stalls, and a restaurant and retail at the ground floor to cater to the theatre clientele.

As part of the Holland Team, Conco is performing all of the cast-in-place concrete, rebar, formwork, shotcrete and concrete pumping for this signature property. The small footprint with minimal lay-down area and five-day form cycle present challenges that require constant communication and coordination with all trades on site. Conco will be utilizing a perimeter protection system and perimeter netting system to ensure the aggressive schedule is met without jeopardizing the workplace. As of August 1, Conco is on schedule having recently completed the 12th floor. Conco will top out the project January 22, 2014.

815 Pine is designed and constructed to achieve LEED Silver status. The project is scheduled to be completed in April, 2015.

The natural beauty of the Northern California coastline has sometimes wreaked havoc on the coastal communities of Moss Beach and Montara. During the rainy season, mud slides become a frequent occurrence often leading to the shutdown of Highway 1, the only artery leading north to San Francisco.

The resolution to this problem was to build a tunnel through the mountain that will bypass the parts of the coastline most prone to erosion. Public input from local residents reflected a high level of concern that the fix not detract from the natural beauty of the California coastline. Therefore, great attention was made to make sure the tunnel blended in with its surroundings.

Robert T. Hill & Associates, a well-respected artistic firm with 25 of years experience in concrete sculpture, teamed up with Conco on this high profile project. The task at hand was to reconstruct boulder formations out of concrete to blend into the natural formation that existed above the Portal at the south end of the tunnel.

The project was designed by Cal Trans in 2006, but not started until March 1, 2012. Applying shotcrete was extremely difficult as the grade was at 1 to 1 ½ slope. This required the use of man lifts and cranes and sometimes having crews tied off from the top and rappelling down from the top.

The tunnel is scheduled to open in late 2012 before the start of the next rainy season. As a testament to the work from Conco and Robert T. Hill & Associates, the work performed blends into the hillside making it virtually impossible to distinguish between the rocks made by nature and those made by man.
