The Oaks project was an important win for Concrete Services, since the end of 2008 projects of this size have been far and few between in West Coast region of the United States. The project has many aspects of concrete construction on it including foundations, large slab on grade placements, cast in place walls, tilt up panels, concrete stairs, concrete monument sings, truck paving, curb, gutter and sidewalks.
Concrete Services is self-performing all of the concrete work on the site and at the height of construction will have between 75 and 100 craft employees dedicated to the project.
According to Shawn Barnes, Operations Manager of Concrete Services, “With over 50,000 cubic yards of concrete to be placed in approximately 11 months is no small undertaking. There is 1.3 million square feet of slab on grade, 360,000 square feet of tilt-up panels and 236,000 square feet of truck rated paving.” The project specifications require 6” of compacted 3/4” aggregate base, reinforcing of #4 18” O.C. around the perimeter 30 feet wide, and the construction joints call for #6 dowels with continuous #6 dowel baskets at every control joint.
“We have worked with Somero products for the past 14 years by renting operated screeds that we would utilize on various projects,” says Barnes. “We knew at bid time it was crucial knowing the only way to be competitive on this type of project, given the size and flatness requirements, that a Laser Screed was the only way for Concrete Services to meet and exceed the clients expectations.”
With a project of this magnitude placing large light industrial flooring with specific FF and FL requirements, Concrete Services decided to partner with Somero Enterprises, Inc. and purchased a new S-22E Laser Screed model. Barnes continues, “With the California weather conditions, we needed to have something that would get it down fast and flat to beat the heat and winds.”
Why The S-22E Laser Screed Model?
With over 1.3 million square feet of slabs to be placed, Concrete Services only knew of one company that they would want to partner with to make this a successful project. Once hearing about the S-22E Somero model, the company states, “The S-22E has made it easier to achieve the results we are looking for, the soft touch landing eliminates the need to have someone straight edge the touch downs and the quick pass allows us to correct concrete that was placed a little on the high side. The operator controls are very user friendly. The location of where the operator is seated make this the safest machines to work around. Originally we had just planned on placing the slab on grade but after using the machine we have decided to also use the S-22E to place the exterior paving with it as well.”
The true hidden gem behind the machine is the fact that with over 1/4 million square feet already installed, Concrete Services has been able to exceed the owner’s expectations. From the very first placement after on-site training provided by Somero, Concrete Services delivered and averaged an FF 95 and FL 86 and has since averaged FF 109 and FL 82, with the first building being a sloped floor placement.
Tom Jodry, Sr. Vice President - Development Management of Trammell Crow Company states, “As a developer and owner, we cannot be more pleased and impressed with the quality of the flatness and finish of the Oaks slab-on-grade production using the new laser guided power screed to date. Most notably, the flatness standard has averaged nearly double the specification, concrete waste is de minimis, and we are realizing significant schedule acceleration.” Currently, Concrete Services is running over two weeks ahead of scheduled plan.
