Innovative civil engineering solutions and services.
LFA provided construction inspection services to both INDOT and IDNR for the S.R. 23 at Koontz Lake Dam and Road Reconstruction. This unusual project included realignment of S.R. 23 and construction of a new embankment (30,000 cubic yards) for the dam, roadway, and spillway structure in combination with a two span bridge. The project incorporated 3,400 cubic yards of concrete as part of the dam and bridge construction. The project involved relocation of an existing ditch and construction of a nearby 16 acre wetland mitigation site. Temporary and permanent erosion control devices were installed and maintained. Project improvements required the demolition of one house and one business.
LFA provided complete construction inspection services in accordance with INDOT and IDNR criteria and played a key role in all on-going construction engineering decisions. Construction documentation was completed using INDOT’s SiteManager software.
LFA provided construction inspection services for Johnson Road over Geyer Ditch bridge replacement project. This project replaced a two span continuous reinforced concrete girder bridge built in 1925 with a three span continuous reinforced concrete slab bridge. The project included approximately 2,000 feet of new roadway construction with subgrade treatment, full depth asphalt pavement, shoulders, drive approaches and guardrail. LFA assisted coordination with the Electric Utility Company for scheduling power outages for the 96 kilovolt transmission line that spanned over the structure. The outages were required to allow the Contractor to safely drive the piling for the structure’s piers and abutments. Additionally, LFA coordinated with the designer and INDOT’s Geotechnical Division to ensure the proper bearing values were being achieved during the pile driving operations. LFA ensured that the local residents had access to their property at all times. LFA verified that the Contractor correctly implemented their erosion control plan to minimize the impacts of construction to Geyer Ditch.

These bridges, located in Valparaiso, Indiana, required rehabilitation. LFA provided personnel to assist INDOT’s Project Engineer during construction. Coordination with the Railroads, various utilities and other agencies were performed during construction.
LFA provided construction inspection services for the North Oakland Avenue reconstruction project in Nappanee, Indiana. This project included new storm sewer, HMA pavement, concrete curb and gutter, modular block wall construction, signal loop installation, guardrail installation, and multiple Maintenance of Traffic phases. Project challenges included maintaining continuous access to a golf course located adjacent to the project, phasing construction with local festivals, and numerous encounters with an unknown drainage tile which ran parallel to and in conflict with the new storm sewer trunk line.
Construction phasing was also coordinated with the City of Nappanee so that several local businesses (bank, grocery store, golf course, doctor’s office, retirement center) and the City’s major festival would experience minimal disturbances through construction. These provisions were included in the contract documents and were able to be monitored in the field by our construction inspection staff.
LFA provided construction inspection services for the Boston Street/Larson Street and S.R. 2 Intersection reconstruction project in LaPorte. This intersection improvement project included HMA pavement replacement, significant utility relocations (NIPSCO, Verizon, Comcast), multiple Maintenance of Traffic Phases, new storm sewer construction, water main relocation, modular block wall construction, installation and maintenance of erosion control measures and traffic signal installation.
Project improvements required the demolition of two houses and one business. LFA ensured the Contractor secured the proper IDEM permits and disposed of abandoned underground storage tanks in accordance with State and Federal regulations.
LFA also ensured the Contractor coordinated with the Norfolk Southern Railroad during the jack and bore of a 60 inch steel casing pipe under their tracks for the proposed 36 inch storm sewer. LFA coordinated with the City, local residents and businesses to ensure that access was provided to their properties during construction.
LFA provided construction inspection services for the reconstruction and widening of Miami Road between Jackson and Kern Road including significant utility relocations, new storm sewer construction, curb and gutters, sidewalks, drives, traffic signal installation, QA/QC PCCP paving and coordination of local detour and maintenance of traffic operations with South Bend Community School Corporation. Project issues included extensive utility conflicts and resident access coordination. LFA ensured coordination with the local residents for proper advanced notification of alternate routing of access for homeowners.
LFA provided construction inspection services for the roundabout and reconstruction of the Bittersweet Road and Cleveland Road intersection including significant utility relocations, chemical subgrade modification, installation of roadway luminaries, installation of a 3-sided precast concrete arch on Bittersweet Road over Juday Creek and another on Cleveland Road over Juday Creek, curb and gutter installation with turn-outs to remove water from the roadway, infiltration ditches to retain and slowly release the storm water collected into Juday Creek. The roundabout included center landscaping and ornamental concrete.
LFA ensured coordination with the local school corporation and emergency service providers for proper advanced notification alternate routing of buses. Proper installation and maintenance of erosion control measures was particularly critical with the proximity and sensitivity of Juday Creek.
LFA provided construction inspection services for the complete reconstruction of the Linden Road Bridge over Heston Creek. The project was located in a peat area and adjacent to wetlands with a high ground water table. Expanded Polystyrene (EPS) Fill was used to minimize future settlement. A hydrocarbon resistant membrane was placed over the EPS Fill complicating guardrail installation. LFA worked with St. Joseph County, INDOT, the designer, and the contractor to come up with a guardrail installation acceptable to all.
The project included approach pavement replacement and coordination of local detour. LFA ensured that erosion and sediment control measures were in place to protect the wetlands. Relocation of a fiber optic and conventional communications line did not occur prior to the project and LFA assisted with utility coordination to minimize impacts to construction schedule.
This bridge, located in Gary, Indiana, was replaced with a structure that conformed to Railroad Standards for vertical clearance. LFA provided personnel to assist INDOT’s Project Engineer during construction. Coordination with the Railroads, various utilities and other agencies were performed during construction.
LFA provided construction inspection services for the Indiana Avenue Bridge Rehabilitation project in Goshen, Indiana. The bridge rehabilitation project included replacing substructure and superstructure steel, approach recon-struction, guardrail installation, maintenance of traffic, wing-wall and abutment rehabilitation, and bridge cleaning and painting.
In order to complete the approach work and main-tain construction access, the rehabilitation project required special coordination with the City of Goshen and the two projects adjacent to either side of the bridge. As construction proceeded, LFA and the contractor were able to identify additional areas of the bridge that required rehabilitation.
LFA, the contractor, and the LPA worked in concert to provide a plan and schedule that would allow for the additional work to be completed in an acceptable amount of time. Bridge cleaning and painting were an integral step in the completion of the project and longevity of the bridge. The paint removed from the bridge contained trace amounts of lead and therefore required special removal and trans-port. LFA prepared and coordinated the submittal of the Hazardous Material Waste Streaming Permit and ensured the contractor adhered to the project specific containment plan during the cleaning and painting process.
