Shawn W. Shawn Daw ODOT Sr. Project Inspector (541) Cell (541) Office From: Rodney L Grehn [mailto:rodney.grehn@cityofmedford.org] Sent: Thursday, March 06, :03 PM To: DAW William S Subject: Hwy inch Water Line Project - Construction Questions Shawn, Good afternoon. We had our mandatory pre-bid meeting today for the installation of the proposed 14-inch water line along the south side of Hwy 62 near Hubbard s Hardware and Lava Lanes Bowling Alley. Below is a list of contractor questions that came up in this pre-bid meeting. I ve attached our plans (bid set) and our project schedule for your reference. Could you please review these questions, then give me a call so we can discuss them over the phone. Our bid opening is on March 25 th, and I d like to respond to these contractor questions as soon as possible, hopefully next Monday if possible. 1. Will the crossing work be required to be done at night? The Whittle Ave crossing can be accomplished during the day with flaggers and appropriate TCDs. The installation across Hwy 62 will not be allowed between the hours of 7am and 7pm (typical Hwy 62 lane restrictions). In both cases, as with all phases of construction, the Contractor should provide a comprehensive TCP (Traffic Control Plan) showing all TCDs and closures, including Flagging stations and lights for night work. 2. Will slurry be required in the trench backfill or crushed rock? Our experience with pipes under/crossing roadways has led ODOT to prefer Class E CLSM slurry backfill above the pipe compaction zone (See RD300 and RD302) vs. a ¾-0 aggregate fill. For those areas outside of the roadway, aggregate backfill is standard 1

8 practice. Please note that there is a rapid set CLSM commercially available to assist the Contractor in reducing the time of lane closures. 3. Will trench plates be allowed or will paving be required each day? Trench Plates would be allowed on the Whittle crossing but NOT on the Crater Lake Hwy crossing. Trench Plates are not allowed on State Highways that have pre-construction posted speeds greater than 35mph (see Std Specification Section , bullet number 14). Please note this restriction includes the Highway shoulders. 4. If paving is required, how does slurry backfill work? Hopefully the contractor will stage the work using a highearly material that sets within 1 hour. The Contractor will need to contractor their supplier for specific material performance guidelines to determine what length of pipe can be installed for each 12hour shift. 5. What is the thickness of a.c. paving replacement required? Please refer to Std Dwg RD Does ODOT have off-site easement ( construction easements) on the adjacent properties and will the contractor be allowed to use the easements? Proposed construction easements are not in place at this time. The Contractor will need to contact Roger Allemand to determine if any easements are valid prior to construction. 7. Will ODOT allow the southerly bike lane/shoulder/drop lane to be closed during construction (utilized for construction trucks) of the water main? Closing the shoulder/bike lane would require a comprehensive TCP showing the TCDs and would most likely only be allowed between the hours of 7pm and 7am. Note the Contractor would also be required to provide alternate routing for Pedestrians and Bicycle users, including devices and signing. Thanks, Rodney L. Grehn, P.E.
