INTRODUCTION AND PROJECT SUMMARY NMG Geotechnical, Inc. (NMG) has prepared this cost estimate for geotechnical design services for the expanded development associated with the Tustin Ranch Road improvements within the Tustin Legacy development. The expanded development was not part of the original scope of work in the prior proposal prepared in July 2010. The additional scope of work is based on current project design information and our preliminary review of the expanded grading plan for the road and associated building pads prepared by Hunsaker and Associates. The expanded project now includes Neighborhood B, the land parcel north of the loop ramp, four building pads in Neighborhood G north of Warner Avenue, numerous detention basins, the pedestrian bridge embankment, extension of Park Avenue, and a segment of Legacy Road, and other design items described below. At this time, NMG has performed an initial review of the temporary shoring proposed for the Tustin Ranch Road bridge adjacent to the existing railroad easement and provided recommendations for design (of soldier piles and tie-backs), provided geotechnical review and input for the alternative CIDH pile foundations for the bridge, performed geotechnical review for a new Verdura retaining wall, and ongoing meetings and communication with the project design team. Some of the expanded project azea extends into areas of the site that had have no or little prior work and thus will require additional field exploration to identify the subsurface conditions and geotechnical constraints. 17991 Fitch • Irvine.
