If high winds and severe weather are encountered during project work dates, leaving the RCN nets up after work hours could be hazardous. The past Project that our company scaled in Montana this was not a requirement for project, do to high winds. Even with concrete blocks securing RCN they still would move back and forth from inside paint line to MRB often times getting hung up. Would the contractor be able to drop the nets during non working hours if the scaled areas present no risk to traveling public?

Can a contractor drop the RCN Nets during the scaling of upper benches and Traffic stops? Scaling from that height puts the Crane in danger of being hit because the rocks get re-routed many times from bench to bench.

We foresee 10-15 days to build and modify crossovers and then 80 days to scale and complete bridges, excavation, etc on south bound side while traffic is detoured to North bound side. Once this work is complete, milling and paving both north and south bound sides is estimated to be 15 days, plus 15-20 days for guardrail and other misc. work; and then remaining bridge work on north bound lanes is estimated to be another 50 days. Then remaining seal and cover, epoxy, etc is at least another 10 days. Please add 80 days of contract time.

If RCN have to be up during non working hours the Crane companies are saying they will need a operator with the Cranes during non working hours in case of hazards. This could increase the cost road protection significantly. Can you please state if this will be a requirement?

Due to the rock scaling and bridge work on this project we have some concerns with Special Provision #18 (Traffic Control and Sequence of Operations) along with the 120 days of contract time. The phasing requires that traffic is to be crossed over to the northbound lanes and all work including rock scaling, bridgework, milling and asphalt paving is to be completed in the closed southbound lanes. Traffic is then to be switched so the contractor can perform the bridgework, milling and asphalt paving on the northbound lanes. The rock scaling bid item is set up for 4,060 hours which could take anywhere from 3 to 5 months depending on the number of scalers working the slope. The time frame to complete the rock scaling will dictate the sequencing of all other major items of work under this phasing requirement. We ask that the phasing be changed to allow that once the bridgework and quardrail work is completed on the southbound lanes it can be switched between the median barrier crossover at mile post 159.14 to the median crossover at mile post 163.57 to allow the same work to be completed on the northbound lanes while the rock scaling continues on the south end of the project in the southbound lanes. The polymer overlay, remaining guardrail work, milling, asphalt paving and chip seal can then be completed under lane closures once the rock scaling is complete. We also request that an additional 60 days of contract time be added to this project.
Answer
Submitted: Friday 09-MAR-2018 04:05 PM
The proposed sequence of operation modifications are acceptable. Additional working days will be added to the contract by addendum.
