Scope Of Work
This project involves the rehab of NB & SB Bruckner Expwy bridges over CSX and Amtrak Railroads. Judlau Contracting, Inc. is the Design-Builder, and HDR is responsible for the preparation of contract documents required for the construction phase. Munoz Engineering, P.C. is Subconsultant to HDR to perform survey and prepare survey base mapping documents and bridge clearance monitoring survey.
Roadway Level Survey
Munoz was tasked with developing a topographical plan of the bridges and approach roadways without disrupting traffic patterns. We used a combination of survey techniques including High Definition Surveying (HDS 3D laser scanning) to acquire high quality survey data under an extremely tight schedule. Using the HDS data we were able to produce a full topographic survey of the roadway (including plotted roadway cross sections) in a fraction of the time it would have taken using only conventional methods. The entire survey was conducted without disrupting any traffic.
Track Level Survey
Underneath the Bruckner Expressway a similar situation existed. Munoz was tasked with performing a detailed survey of the bridge structure and track level with very limited access to the site due to conflicting railroad restrictions. Again we were able to employ HDS techniques to acquire the needed survey data while adhering to the railroad access restrictions.
