Pedestrian Sign Footings- Boston University, Longwood Ave; Boston
|
ABC Soils excavated, fabricated and installed sign footings throughout the Longwood Avenue hospital area. ABC Soils utilized vacuum excavation and pneumatic air tools to unearth and utilities potentially located within the designated foundation areas. This technique is safer and more reliable than traditional excavation and Dig Safe due to the high potential of unmarked subsurface utilities in the area. ABC Soils then installed rebar cages within the excavations, followed by cement pours and refinishing of brickwork. ABC Soils also performed similar work at Boston University, Logan Airport, and along the South Bay Harbor Trail.

Excavation Work At Electrical & Natural Gas Substations
ABC Soils excavated soil at electrical and natural gas substations at locations across New England including Bridgewater, Smithfield, Palmer, Worcester, and West Boylston, where overhead clearance and minimum approach distances inhibited the use of other excavating equipment. Soil was excavated so that footing pads for transformers could later be installed for National Grid. Special electrical hazard equipment and safety protocols were utilized by ABC Soils for this work and also for excavating trenches for utility location and clearance purposes at the these and other substations.

Filter Media RemovalABC Soils has removed filter media from public drinking water supply treatment tanks for several municipalities including Dartmouth, Grafton, Maynard, Exeter, Merrimac, Scituate, and Plainville. Graded pea stone, green sand and anthracite were removed from the treatment tanks through a 6-inch vacuum excavator hose; media in the tanks was only accessible for removal via an opening the size of a manhole cover. Some other municipalities that ABC Soils have provided this service for include Wellesley, Needham, and Natick.

Water Main Inspection; Medford WABC Soils excavated trenches in the street to locate a water main. Horizontal ties were taken to locate the utility, then the hole was back filled and compacted, and temporary cold patches were applied until the completion of the project where hot mix was applied. ABC Soils also opened some larger holes for pipe integrity inspections. At 8 locations across the town, we opened up 4' x 6' holes. After removing the asphalt and the concrete underlayment, we dug down to the pipe and halfway around it to expose it for inspection. We backfilled with clean fill, compacted, poured concrete, and applied hot mix asphalt patches.

Retaining Wall Repair & Stabilization; BostonABC Soils was hired by the homeowners to repair a retaining wall on Bunker Hill Street in Charlestown that was being pushed out. The east wall had previously been repaired by installing a deadman and tying it to the wall and holding it in place. Our work included putting in a new deadman, anchoring it to the original deadman, and installing ties to the south wall. In addition, ABC Soils cut out a crack in the wall and repaired it, and installed a trench drain to collect the water. The disturbed area was paved to complete the job.

Water Main Corrosion Study; Boston
ABC Soils installed fifty-six borings with vacuum excavation equipment within the roadbeds of various streets throughout Boston and its surrounding cities. These borings were installed to locate and provide access to existing steel water mains for corrosion study purposes. The work took place sporadically over the course of several months as was dictated by procurement of permits and typically entailed first approximating the location of the water main in the street with a magnetometer, once located, saw cutting through the pavement of the roadbed and vacuum excavating down to the water main which was typically found between five and seven feet below grade, and then, depending upon the results of the initial testing, either backfilling the boring and patching the roadbed or installing conduit and a road box for future access to the water main.
Sewer Main Monitoring well installation; North Andover
ABC Soils installed numerous borings between five and twenty feet deep with a truck mounted vacuum excavator to locate a sewer main servicing the City of North Andover for the Greater Lawrence Sanitary District. This work was conducted to monitor for settling of the sewer main. ABC Soils previously conducted research on sensor installation methodology for a research and development company.
