They do not include drawings for modifications to the structures, such as joint replacements and guardrail revisions and may not completely represent current conditions.  Thus, some of the information contained in these documents may be out of date or not applicable with regard to the advertised project.  The contractor should not rely solely on the as-built drawings provided for bidding purposes nor does any data in these files supersede the data in the contract documents.  AS-BUILTS

The preliminary plans showed 370 working days for contract time. When the advertised plans came out the contract time was reduced to 300 working days. After building a schedule for the project, it is apparent that the 370 working days will be required to construct the project without working double shifts and large amounts of overtime which will drive the project costs up. Please consider changing the contract time back to 370 working days.
Answer
Submitted: Tuesday  08-JAN-2019 09:59 AM
Contract time has been changed an addemdum will be issued.

Special Provision Number 2 Contract Time is replaced with the following: 
2.         CONTRACT TIME [108]
            The work begins on the effective date stated in the Notice to Proceed (NTP) and is to be completed in 350 Working Days. The NTP will be issued with an effective date of March 25, 2019. Sequence the work to allow traffic to be routed from the PTW to the new alignment no later than November 15, 2020. Complete work on all elements of the new bridges and roadway segment, excluding seal coat, final pavement markings, obliteration of PTW, seeding, and structure removal, before routing traffic onto the new alignment. The Project Manager has sole authority to determine when the new alignment may be opened to traffic. Failure to route traffic onto the newly completed alignment by November 15, 2020 will result in the department assessing contract time until traffic is routed onto the new alignment.

Per Special Provision 41 all items associated with Embankment Foundation Preparation are paid for under the Special Borrow-Neat Line bid item. With these items being a small portion of the Special Borrow-Neat Line bid item, high probability of quantity changes and unknown excavation costs due to possibility of significant dewatering. The unit price for Special Borrow-Neat Line would not cover the high probability of quantity changes and possibility of high excavation cost. Would MDT please add a separate bid item for Embankment Foundation Preparation?
Answer

A bid item for Embankment Foundation treatment will not be added.

There is EXTREMELY LIMITED access for the work between the new bridges:
1)  It appears MDT has not acquired any easements or ROW from MRL for access and construction - only final configuration. Please confirm Contractors are responsible for obtaining and paying for a) all track grade crossings, b) any access/haul roads on MRL property, c) any staging/storage areas on MRL property.
2)  Using MRL grade crossings as haul roads - constant truck traffic will likely require track maintenance to maintain alignment and grades - will Contractors be responsible for these maintenance costs (work will be performed by MRL)?
3)  Will MDT participate in any costs associated with MRL land usage? Single track at-grade crossing $6,500, staging/storage areas $0.11/square foot/year, access roadway lease $0.10/square foot/year?
4)  Exhibit "C" 1.01.07 requires a baseline track survey and monitoring (interval unknown). Will this be performed by MDT?

Previous Question #29:
1)  It appears that the pedestrian tunnel will need some kind of lane-separation (old from new) shoring to be able to complete. Is this cost to be included in the temporary shoring bid item?
2)  MDT's answer to complete the entire pedestrian tunnel before swapping traffic is not possible to construct - Stage 1 needs to be complete with traffic put on to the new alignment prior to any work being done under the existing road - Stage 2. There is no other place for traffic to go unless all traffic is routed over the old bridge and through the town of Toston via the by-pass. It would appear Stage 2 work needs to be allowed to be performed after 11-15-20 or whenever traffic is on the new alignment. Please re-consider your response.
Answer
Submitted: Tuesday  22-JAN-2019 04:17 PM  
1)  It is acceptable to install the portion of the pedestrian tunnel beneath the new roadway alignment stopping short of the PTW and at a point where shoring or other temporary means to support the PTW is not required. Construct the new roadway alignment at the tunnel crossing location to accommodate a minimum 12 foot wide lane in both directions of travel.  Submit a work sequence and traffic control plan to the Project Manager for review and approval prior to beginning work on the pedestrian tunnel.  
2)  The entire pedestrian tunnel does not need to be installed before transferring traffic to the new roadway alignment.
