Below is one of the current soil and groundwater remediation projects FABCO is working on at the present time in Red Bank New Jersey, the former residence of Florence Forgotson the project started on January 18, 2010. FABCO will post photos of the project as the project progresses.   The project structure is being prepared to move to a staging location on in order to do perform the soil and groundwater remediation. The reason for the move, the soil underneath the structure has been impacted from and underground oil tank failure which impacted the soil 20 feet below the structure.  This structure is over 100 years old, wooden framed house with a brick foundation.     

Above shows the structure before the project started, and how the structure must be prepared in order to move the structure 100 feet forward to the staging area.  

The support steel I-beams are placed underneath the structure, to lift the structure all at once. 

Support steel I beams have been place under the structure for the lift. Slide Rails and rollers have been place to move the structure from the foundation area out to the staging area 100 feet away.    

The structure move is being performed by Wolfe House Movers, LLC.of Bernville, PA. Prior to the move FABCO obtained all building and zoning permits with the township and prepared the structure for the move.

You are looking at the base of the 50 ton chimmey above that has been liffted and supported.  The Stucture will be moved next week, and FABCO will then remove the foundation to clean the project site, prior to removing the petroleum impacted soil.  

January 29, 2010 The structure has been moved back to it staging location, and FABCO is ready for foundation demolition.

February 1, 2010, Today FABCO started the demolition of the foundation, all the concrete and brick was sent to an approved recycle facility to make crushed concrete, used as stabilization material for road bases.  

The demolition material is loaded out on to trucks and transported to the facility for recycling.  

The demolition material is separated from the excavation overburden soils. All soils above the foundation are clean and will be stored on site for reuse.    

Foundation removal completed, all demolition materials loaded out for recyling  (2-2-10)  

Installing a tracking pad, to keep the site clean, and maintian a safe entrance to excavation area. 

March 9, 2010- Begin installation of Soldier Steel H Beams and Wood Lag support wall to secure neighboring property line, FABCO’s off loading leads for Steel H-beams to be driven in ground 38 feet below grade by Atlantic Pile Inc. out of Middletown NJ.

40 foot Steel H-beams 14 X 73 to be driven in ground 5 feet on center to support the neghboring property and structure from sliding into the remedial excavation, once the cut is made along the property line.  

 Pre-drilling steel beams locations along property line to keep vibration down while driving piles.

Installation of Steel H-Beams with Pile Driver and Crane, with vibrating analyses being performed at all times during pile driving operations, by  VIBRANALYSISIS INC. a firm out  of Bronx New York who specializes in monitoring construction sites for any type of vibration and records it on the field monitoring equipment installed on site.  The beams are driven down to 38 feet to hold back the cantilever wall and preventing any sliding of the foudation.    

A steel beam and wood lagging support wall system, had to be installed to excavate soils five   feet away from the property line to a depth of 14 feet at the wall, the soil impact deepen closer to the former oil tank location  30 feet away from the property line.

The support wall will allow FABCO to perform the remedial excavation while maintaining the integrity of the surrounding soils. The next phase of the project is to install a site de-watering system with carbon filtration system as pictured below. This is made up of several different components. A permit has been obtined and issued by NJDEP to discharge the treated groundwater to the Navasink River.

         Two- 2,000 Lb. Carbon Canister

        One 25 yard Sediment Tank Filter   

The sediment tank in conjuction with the carbon system, keeps the sand out of the carbons canisters which prolong the life of the system. The oil seperator in the treatment trailier polishes off the discharging water. The tank filter down removes sand to 13O mircrons before the groundwater goes into the treatment trailier oil water seperator and then the carbon canisters, keeping the system bag filters clean and free of cloging sedimentent, the bag filliter are changed every 24 hours to keep the system clean. You can drink the discharging water. 

This is a picture of the groundwater, as it leaves the 500 gallon oil water seperator inside the treatment trailer. The water is then pumped to 4 bag filters prior to going to the carbon canisters units.

This is the inside of the treatment system trailier, the oil water seperator is the stainless steel tank in the background. The bag filiter system and system totalizer is what is mounted on the rack that you are looking at.  The meter keeps the numbert total gallons treated and discharge. The system is checked several times a day for its integrity and permit complanice.   

The 4 system bag filters are changed everyday and gallon totals are logged in 4 times a day  

The carbon units and unit trailier are very compact and fit anywhere  

 A vacuum well point system has been installed to excavate and back fill the excavation with compaction testing by a Proffessional Engineer, the lifts are compacted at 12 inch intervals to 95 % compaction or better.

          Electric and vacuum pumps maintain the control of the groundwater 24 hours a day

The over all excavation length is 100 x 65 and in some portion of the excavation. The excavation sidewalls are sloped for safety, the main excavation is bench at 10 feet below grade while the petroleum impacted soil is at a depth of 20 feet below grade, some areas have as much as 13 feet of clean soil over 7 feet of petroleum impacted soil.    

    Each 12 inch lift is checked and testing is performed to insure 95 percent compaction

The remedial excavation has been excavated and back filled and compacted within the shoring box in the deeper portions of the excavation. Excavation depths of 20 feet.  

June 9, 2010, the soil remediation is now at 75 percent completed, with all post excavation soil sample results reported FABCO are non-detect. Engineering compaction test have been done and the measurment reading's are at 95 percent or better. 

FABCO has collected over 12 post excavation soil samples, and 17 waste classification soil samples for the facility. Clean overburden soils are staged behind the excavator for reuse.  

The excavation has been bench down to 10 feet to get at the soil contamination between  13 and 20 feet below grade. The vacuum De-watering system has been moved and installed again for the final time.

The contaminated soil is loaded and transported to the facility on a daily basis. The clean soil covered you see in the background at the top of the photo has been covered with plastic for dust control and consideration of the neighboring property, and will be reused in the excavation during the reconstruction of the foundation.  

Soil excavation of petroleum impacted soil within the shoring box was a slow excavation  process but effective due to the depths of contamination (20 Feet).  Each section had to excavated down and compacted back up. The soil on left, inside the box is the contaminated soil, the excavator's on the right have to move the soil once excavated in a continues waste flow of disposal off site to the recycling facility. Each unit helps the other.    

On June 24, 2010 the soil remedial excavation task of petroleum impacted soil was completed, 2,645 tons of petroleum impacted soil was excavated and transported to a recycling facility for reuse. The petroleum impacted soil was replace with clean virgin bank run materials from the Mc Dowell pit in Neptune, NJ (AKA Blue Berry Acres)  132 truck loads of soil was transported to the site by FABCO INC.       

Next step is to prepare the site for the house move and reconstruction of the foundation.  

On June 25, 2010 the soil remediation excavation task has been completed.  

During the remedial excavation the clean overburden soil was staged on site for reuse now.  

The Clean overburden soil was staged on the other side of the house during the remediation excavation for easy load out for it's return use to the excavation, this save time and money.

The next step of the project is to dismantle the the groundwater treatment system and get ready to move the house back on the new foundation.
