Inquiry #7: Regarding the use of the "Trench-in Pavement Method" , section 87-1.03B allows the use if the delay to vehicles will be less than 5. minutes. The "Trench-in Pavement Method" is prohibited for use under freeway lanes or freeway to freeway connector ramps.

As i understand it US State Route 17 (SR 17) is a State Highway and is not designated a Freeway. So the choice or option to utilize the "Trench-in Pavement Method" should be left up to the contractor. Unless a response to our inquiry is received we will plan on utilizing the Trench-in Pavement Method" for conduit installation and we will discard the Departments response to Bidder inquiry 3. Please advise.

Response posted 03/12/2020

Response #2:The Departments response to Bidder inquiry # 3 is still valid. This project is on the segments of State Route 17, which is designated as State Conventional Highway. Still, the choice of trenching options will be based on site conditions and the Department's preferences. Both directional drilling and trenching on the dirt are acceptable methods. With regards to trench in pavement method, the Contractor shall prove to RE that they could not or have a big difficulty to trench on dirt before using trench in pavement method.
