I-95 Section 100

Findling, Inc. - I-95 Section 100 Project

Findling provided Construction Inspections and Material Testing Services on the I-95 Section 100 Project in Baltimore Maryland for the MDTA (Maryland Transportation Authority). Our responsibilities included conducting on-site construction inspections and testing of soils, concrete, steel and hot mix asphalt (HMA); keeping daily records of work performed; keeping daily records of labor, equipment and material on the site and hours worked; preparing field sketches of constructed work; preparing quantity estimates; and attending/ conducting construction progress meetings. Findling served as the owner's representative "eyes and ears" on site to protect his interest and minimize contractor claims by keeping detailed and accurate records. We established continuous coordination and communication between MDTA and contractor.

Findling provided more than 5 certified technicians and inspectors at the various intersections, bridge, ramp and roadway widening sections of the project, and an inspector for the I-95 ETL laboratory (by Maryland Department of Transportation) located near the Section 100 Project Management Office.

Findling, Inc. - Cox Creek Project
Cox Creek

Findling, Inc. - Cox Creek Project

Findling was retained to provide Geotechnical Engineering, Construction Oversight, Materials Testing Services, and Geotechnical Instrumentation for the construction of the Cox Creek Dredged Material Containment Facility. The project site is located on the west bank of the Patapsco River just south of the Francis Scott Key Bridge in NE Anne Arundel County, Maryland. The facility covers an area of about 115 acres. This site was initially developed in the mid 1960's for disposal of dredge material, and consisted of a perimeter dike on the north, east and south sides. The facility was abandoned in the late 1960's and 1970's. The Maryland Port Administration purchased the facility and led a contract for the rehabilitation and raising of the perimeter containment dikes so that the facility could be used again for disposal and dredge material from the inner harbor. Findling was retained to provide Geotechnical Engineering and Construction during construction of the facility

The services Findling, Inc. provided for this project included:

  • Test borings and in-situ testing to evaluate subsurface conditions and strength characteristic of foundation soils
  • Geotechnical engineering design for the containment dikes and instrumentation during construction
  • Installation and monitoring of geotechnical instrumentation including piezometer, inclinometer and observation wells
  • Full time field engineering services for slurry wall construction
  • Full time materials technician to monitor and test fill placements and geotechnical consultation during construction
  • Laboratory testing of soil and slurry wall samples
  • Attended progress meetings and other meetings with design team and contractors as requested

Findling, Inc. - Masonville DMCF Project
Masonville DMCF

Findling, Inc. - Masonville DMCF Project

Findling, Inc. was retained to provide Geotechnical Engineering services for the design of the Masonville DMCF at the Masonville Marine Terminal. The project consisted of designing a containment facility for placement of dredge material from the Baltimore Inner Harbor area. The proposed facility consisted of an earth embankment (dike) about 5,000 feet long to be built in the Middle Branch Patapsco River between the existing Masonville Terminal and the Ferry Bar Channel, extending about 1000 feet into the river. The dike was designed to a maximum height of El. +42 over an area of about 116 acres to provide a design storage capacity of about 16 million cubic yards of dredge material.

In addition to design of the earth embankment, Findling evaluated the subsurface condition within the footprint of the perimeter dike to identify a source of soil for earth dike construction and increase storage capacity, and evaluated the permeability of the proposed dike section for seepage analysis.

Findling, Inc. - Masonville DMCF Dike Raising

Masonville DMCF Dike Raising Phase III

Findling, Inc. - Masonville DMCF Dike Raising

Masonville DMCF Dike Raising Phase III

Initially the dike was to be constructed to El. +10 with on-site soil then raised to El. +42, using reclaimed dredge material within the facility. Initially 5 dike alignment options were considered, and after an initial evaluation of subsurface conditions, one alignment was selected for final design.

Another aspect of the project included relocation of a 48 inch water line between Fort McHenry and the Masonville Terminal which passes under the proposed containment facility. Findling provided Geotechnical Engineering services associated with the water line relocation.

The services Findling, Inc. provided for this project included:

  • Subsurface investigation on water and land
  • In-situ testing to evaluate strength parameter for dike foundation soils
  • Evaluation of subsurface soil conditions within the footprint of the containment facility for use in dike construction
  • Designed the earth embankment to a maximum height of El. +42 in stages over the life of the facility
  • Assisted with preparation of specification for dike construction and dredging
  • Met with MPA and Corp of Engineers to review design
  • Provided geotechnical design parameters for thrust block design, cofferdam and pipe line support for 48 in. water line relocation

Findling, Inc. - I-695 and MD Route 26 Project
I-695 and MD Route 26

Findling, Inc. - I-695 and MD Route 26 Project

Findling performed a Subsurface Investigation for the I-695 over MD Route 26 and Milford Mill Road Improvements Project. The scope of this work included drilling test borings in soil and coring rock at the location of the bridge structure, abutments and retaining walls. In addition, borings were drilled for the lane widening, and new ramps and modification of existing ramps. Test borings were also drilled for the proposed Storm Water Management (SWM) facilities, and in-situ infiltration tests were performed. The test borings in the existing roadway were performed during restricted work hours, including night work on I-695 with Maintenance of Traffic (MOT) during the drilling operations. The test borings in the roadway were backfilled with grout in order to minimize future subsidence, and the surface was patched with cold asphalt patch.

The samples from the test borings were transported to our laboratory for additional testing. In the laboratory, moisture content, Atterberg limits, grain size analysis and Proctor Compaction Tests were performed on selected samples. In addition, CBR testing was performed on selected samples to aid in the design of the pavements.
