Structural Steel, From the Top Down

At the corner of Village Green and Preserve Parkway, the structure of the new USS Real Estate Building is starting to take shape.

Vertical steel columns and horizontal I-beam framing are completed to the roof.  This skeleton frame was constructed in a rectangular grid to support the floors, roof and walls of the building.Composite steel floor decking, formatted to ASTM standards, is being installed.

Concrete Forms for Basement Walls Are Erected

Concrete Starts at The Preserve

Before the concrete for the foundation walls and main building body can be poured, forms and rebar structures must be built. The rebar is to ensure structural support and increase strength of the concrete.

Wall foundation concrete poured

The Preserve Building is still getting pours for the foundation and main building body. This is now finished and we can move onto to other parts of the project cycle.

The concrete pours for the supports of the main building body is shown here as the overview of the building site


Foundations begin at USS Preserve

Now that the grading in the foundation area has been completed, the groundwork preparation for the foundation pours started last week.

Concrete pour begins

Concrete pour for rear of building

Now that the reinforced concrete pours have begun, we can move onto the rest of the building slab this week.


Laying Down the Foundation

Survey crews starting layout

Layout work continues

Survey crews began the layout for the foundation. As shown in the photos above, the use of a soil nail wall was successful for the foundation wall near existing structures.

Service Ramp Into Foundation Area

The service ramp for the building pad is shown above as Superintendent Mickey Moman views the survey crew’s foundation layout. The scale of the site work can be seen here.

Stone being placed for foundation

Testing stone after compaction

After the foundation was laid out, the crews placed, compacted and tested the stone for the foundation. The compacted stone backfill will replace any unsuitable material in the foundation. This will ensure that the ground meets the specified bearing properties.



Excavation and civil work continues at the Preserve

Excavators working on basement area

Basement area grading shown

Excavation of the basement is nearing completion and should be wrapped up by this next week.

Parking lot area shown

The parking lot structural fill is nearing completion after the recent storms in the area. This area will be completed in just a few days.

Floor of Basement area

Survey markings on Soil Nail Wall

The survey engineers established bench marks for the floor area of the basement for excavation of the first floor. This will assist us in bringing everything up to grade.

Soil nail wall shown

The soil nail wall that was started last week is now completed. This will ensure that we are able to move forward with the grading and excavation work necessary for completion of the overall project.

The Preserve Site Prep Continues


Grading Preserve Jobsite

After several days of rain, we were able to continue work on the parking lot after some time allowing the site to dry. The early grade work of the site is important as will later serve as the staging area of the building construction.

Test Engineer recording soil samples

The site material was tested for proper density to ensure that it meets the required specifications of the overall build. In the photos above, the test engineer takes soil samples and records findings of the early stages of the geotechnical testing.

Utilizing soil on the site

For the site prep, we are using on-site material, a clay-like soil that has properties perfect for our uses at the building site. If the weather will cooperate, site work will be completed soon.

The Preserve Project Nails It

Site Just Before Clearing & Grading Began

Clearing of undercut and other materials

Clearing of the project jobsite began by first clearing and grading the lot so that the subgrade for the building pad could be prepared.

Subgrade work started

Backfill for the parking lot area

Grading and backfill work began at the job site for the parking lot area and excavation for the building pad as well.

Excavation of Basement Started

Rock removal crews working on Excavation

The first work of the project involved the removal of rock and excavation for the future basement. The excavation lowered the original grade of the building site down 14 feet.

Soil Nail Example

Tecco Mesh System over Geotectile Fabric

Finished product of the geo fabric and soil nails

In what will be the future basement area, the crews installed a geo fabric with Soil Nails. These “nails” are spiral pins that are driven into a bank of earth at various depths to essentially lock the geo fabric and geogrid-style material shown above into the retaining wall. As the Soil Nails are driven into the components and the wall, the pressure locks everything into place.
