The existing Laboratory and Industrial Waste buildings needed to be demolished to make space for the Wet Weather Plant Expansion, requiring the construction of a new facility. Because the new facility was to be located on ALCOSAN’s current Union Parking Lot, the design also included an adjacent multistory parking garage to replace the lost surface parking. The three-story ECF building consists of a new laboratory on the first floor and new office space on the second and third floors. As a subconsultant to AE Works, Sci-Tek was provided the following services:
SURVEYING
-
- Performed a field survey to establish horizontal & vertical control points.
- Performed a survey of existing site conditions which will include details on existing improvements, visible above ground utility appurtenances, measurements of storm drain and sanitary sewer pipe invert elevations and survey of trees and/or tree lines.
- Prepared a topographic survey drawing showing details of the features surveyed, including underground utility information provided by ALCOSAN.
GEOTECHNICAL EXPLORATION
-
- Performed a geotechnical subsurface exploration.
- Selected representative samples of the material recovered for laboratory testing of physical properties.
- Estimated the soil and rock engineering parameters for the materials encountered at the test boring locations.
- Reviewed proposed foundation design drawings and specifications.
- Prepared a final report with conclusions and recommendations.
CONSTRUCTION SUPPORT SERVICES
- Provided responses to Contractors’ Requests for Information (RFI’s) regarding the geotechnical aspects of the foundation design and contract documents during bidding and construction phases.
- Performed evaluation of the Contractor’s probe hole data obtained by test drilling.
- Provided Estimated Caisson Tip Plans based on the data obtained from the probe holes.
