To this point, HLR had no survey data south of the proposed centerline of South Street other than cross sections provided by the development engineer showing existing conditions. At several locations, the existing cross sections did not extend to the proposed right-of-way line. in order to complete the design of the south half of the roadway, including the required embankment and proposed sidewalk, and to quantify the work to be included in the City's construction contract, an HLR survey crew performed a topographic survey to supplement our information to the south of the proposed centerline in this area. This survey work was performed on February 15 and 18, 2008. Design, The supplemental survey data was then imported into the existing point data, a revised TIN (triangular irregular network) was run, and new existing conditions cross sections were generated. After updating existing conditions, HLR completed the design of the south half of the roadway. The geometric requirements had previously been set, but the cross sections required extensive revisions to Include the proposed sidewalk, embankment and excavation and undercut for unsuitable materials. Revisions to the plan and profile sheets were also required, as well as recalculation of roadway and earthwork quantities and updating of summary of quantities, schedules of quantities and engineer's estimate. The design work was performed during March through June of 2008. The man-hours and costs associated with the work described herein is detailed in the accompanying spreadsheet.
