How HCSS Software assisted with this project
HeavyJob was a vital tool in keeping track of labor hours and equipment costs on this project given the multiple work locations. In addition, at several locations differing site conditions were encountered that required the addition of new cost codes to allow our crews to track their work on a T&M basis. Being able to go back and use the HeavyJob reports to aid in the creation of T&M submittals has been a real time-saver.
Project Description:The ODOT Stone Arch Project included rehabilitation of eight stone arch culverts originally built in the mid-1800s as part of the Miami & Eire Canal. Miller Bros. setup and maintained cofferdams and bypass flume pipes at eight separate locations to allow access to the work area(s), and they removed and reconstructed the existing stone block headwalls and wingwalls. They replaced damaged stone blocks with limestone replacement blocks or precast concrete blocks and installed wire mechanically stabilized earth walls behind the reconstructed block headwalls and wingwalls to relieve earth pressure from the newly reconstructed block walls. Some locations required temporary excavation shoring due to the close proximity of existing roads and/or structures. This was done with soil nails and a reinforced shotcrete wall. Temporary shotcrete wall heights varied from 10 feet to 30 feet.
At location S4 HEN-424-10.78, the existing 20-foot span by 10-foot rise by 128-foot-long stone arch culvert was to be removed and reconstructed. The plans showed the culvert sitting on a 3-foot-thick pad of rubble. When the area was dewatered it was discovered that the culvert was actually sitting on wooden timbers. After several months of waiting on direction from Ohio Department of Transportation, it was decided to leave the arch blocks in place and re-line the inside the culvert with a corrugated metal multi-plate arch on a cast-in-place concrete spread footer cast on top of the existing timbers. With a several month delay and a few flood events this location was finally completed in 2014.
At another location, S5 HEN-24-13.56, the existing 34-foot span by 17-foot rise x 127-foot long stone arch was lined with a 34-foot span by 13.1-foot rise corrugated metal multi-plate arch and the headwalls and wingwalls were reconstructed. Location S3 HEN-424-0852 included the installation of a 23-foot tall cast-in-place headwall & wingwalls.
