Intercounty Connector (ICC)
As part of the General Engineering Consultant team (GEC), J.A. Rice, Inc.â€™s (JAR) scope included Quality Assurance surveys on survey control for machine control, stakeout, bridge structures, culverts, subgrades, and paving. JAR also performed field run topography, prepared topographic maps, and set survey control for many of the ICC Wetland and Reforestation Mitigation projects. JAR performed base-mapping for design, stakeout for baselines, boundary surveys, right of way surveys, plat preparation, and easement descriptions for approximately 45 individual sites. The survey sitesâ€™ sizes varied from one acre to over 100 acres. Our scope of services varied from the mainline to the mitigation sites, but usually included the following:
JAR established horizontal and vertical control from two or more known ICC survey control points, JAR would check the contractorâ€™s control to the ICC mainline traverse for automated machine control work, and/or for troubleshooting purposes whenever the need would arise. For the mitigation sites, either Maryland State Highway Administration survey control or NGS Geodetic Control Monuments within the area were used. The horizontal datum was NAD 83/91 and the vertical datum was NAVD 88, both of which are the most recent datums commonly used.
Quality Assurance Surveys
At the direction of the GEC staff, JAR performed checks on stakeout and structures. This included, but was not limited to, limits of disturbance, culverts, bridge decks, abutments, piers and caps, subgrades and test sections, cross slopes, toll gantries, noisewalls, sewer, water, storm drain, and stormwater management facilities. Based on the survey results when compared to the approved plans, JAR filed an online Quality Assurance Oversight assessment. JAR staff participated in bi-weekly Quality Assurance and schedule meetings. JAR also performed control checks on the environmental mitigation sites before the site package was released for construction.
The topographic surveys included grade breaks, tops and toes of slope, spot grades, road edges, curb lines, parking lots, building lines, manholes, pipe inverts for gravity systems, and the surface features that would have impacted the design. The topographic plans usually contained existing contours, locations of survey base line, Maryland State grid coordinates, survey benchmarks, existing utilities (including size and invert elevations of all pipes), location of wetland flags, and elevations of all topographic features including, but not limited to, manholes, drainage structures, buildings, roads, bridges, drives, parking areas, walks, and fences.
Boundary/Right of Way Surveys
The boundary/right of way surveys included research of public land records, preparation of property mosaics, field location of boundary and/or right of way evidence, and determinations of lines. It also included plat and legal description preparations, certifications for acquisition of fee simple, right of ways, and easements for wetland and reforestation mitigations.
Final deliverables included plats, legal descriptions, quality reports, raw files, final coordinates, surface files, notes and sketches, and digital CADD files in MicroStation V8 format.
