The District Project Engineer shall be named at the pre-design meeting.

At the pre-design meeting, the Contractor shall name a Project Manager who will act as a liaison between the DBT and the Department.

8.8 Permits: DBT will be required to obtain a permit from the State or local government having jurisdiction, to perform any non-construction work within the existing ROW and/or limited access.

8.9 Entry On Private Property: The DBT, acting as The Department’s agent, may enter upon any lands within the State for the purpose of inspecting, surveying, leveling, digging, drilling, or doing any work deemed necessary in the execution of any survey authorized by the Director of Transportation in accordance with Section 5517.01 of the Ohio Revised Code and Section 102.6 (inclusive of Sections 102.61 through 102.66) of ODOT’s Survey Manual. Prior to performing said survey, the DBT will send notification letters indicating the date and duration of entry to the affected property owners no less than forty-eight hours nor more than 30 days prior to the date of entry for said survey in accordance with 102.6 of ODOT’s Survey Manual. The DBT shall forward copies of all notification letters distributed to ODOT’s Project Manager. Any subsequent claims for compensation due to damages incurred while said survey was being performed will be negotiated between the DBT and the affected property owners with final approval from ODOT’s Project Manager. Crop and property damage minimization and reimbursement information, together with the crop damage reimbursement formula and Special Waiver of Damage form, will be provided to the DBT by ODOT’s Project Manager. Any

subsequent entries onto private property for the purpose of obtaining additional survey or soil information prior to the submission of the bid will be made in accordance with the procedures outlined in this section.

If there is no potential for actual damage to the property nor substantial interference with possession or use of the property, then no notification is required. However, it is always in the interest of good relations with the public to at least knock on someone’s door to let

(10)

them know what is going on upon their property.

If a property owner refuses the crew’s request to enter upon the property, then ODOT D6 will need to be notified in order to gain a right of entry for survey work or a court order will be needed.

Supplemental Specification shall be

referenced on the Title Sheet of the construction plan.

Post construction BMPs will not be required based on the linear nature of the noise barrier project.

11 RIGHT OF WAY (ROW)

All necessary construction work for the project will be performed within the existing right of way.

The DBT will stake and flag the existing right of way in the field prior to the start of construction and will maintain said stakes and flags throughout the duration of the project.

The DBT will identify and show all right of way encroachments on the construction plans at the Conceptual Review Submission. ODOT’s Project Manager will be responsible for clearing all encroachments on Federal-aid projects in accordance with standard

encroachment removal.

Some property owners have their fences up to the right of way fence. If the right of way fence is removed for noise wall installation, the DBT shall work with the Project

Engineer and provide notice to the property owner. Removal shall be coordinated with affected property owners. This work is incidental to noise wall installation and will not have a separate pay item. The contractor should assume that where the barrier is on or within five feet of the right of way fence, the fence shall be removed.

12.2 DBT Utility Coordination Responsibilities:

ODOT will provide a list of all utilities in the area and will provide available utility plans.

The DBT shall assume that the plans are not “as built”. All public and private utilities shall be field verified by the DBT.

As soon as it is feasible after the final plan is approved by the Department, the Contractor shall stake the existing ROW in the field and shall perform clearing and grubbing within that ROW as required by the specifications and the proposal documents. ROW stakes shall be maintained and updated as needed throughout the project length.

The DBT shall be cognizant of the project's impact on utility facilities. In the event utility rearrangements are required, the project shall not be designed to preclude legal occupancy of the highway ROW by the rearranged utility facilities.

The DBT shall coordinate all existing utilities with construction activities on this project.

The DBT shall insure that potential delays in coordination and relocation of the affected utilities are minimized. The DBT shall copy the Project Manager and the District Utility Coordinator on all correspondence or phone calls between the DBT and each utility. This shall include the submittal of plans to each utility.

A meeting at or near the preliminary review shall be held between the DBT the District Utility Coordinator and the utility owners to determine if any significant utility

relocations can be eliminated or mitigated. “Utility Coordination” is provided as a pay item so that the DBT can locate and identify all utilities in order to prepare conflict free plans. Certain conflicts can be avoided by minor shifts or changes in a portion or portions of a wall or walls. If the avoidance of a conflict requires a reduction of the barrier length or height, ODOT shall be advised in writing prior to preliminary plan development. A location, length or height change to avoid a utility conflict shall not be made unless ODOT grants permission to do so in writing. ODOT shall only grant permission to make a location, height or length change if OSHA rules require that the barrier (or equipment during installation) maintain a minimum distance from the utility.

(14)

Any betterment to the utility's facility and ineligible, or unnecessary, work shall not be a part of the project's expense but the utility company’s fiscal requirement. Determination of eligibility can be coordinated through the District Utility Coordinator. Payment for betterments or ineligible costs shall be made by the appropriated utility through ODOT to the Contractor.

The cost of all utility coordination shall be bid as a Lump Sum Item.

17 PROJECT SCHEDULE REQUIREMENTS

After work begins on a wall, the contractor will schedule work in a way that work is

(17)

continuous until the wall is complete. This will utilize the critical path method progress schedule for short duration projects as per Proposal Note 105.

18 REVIEW REQUIREMENTS

The Design Build Team will walk the project with the Project Engineer to specifically discuss exactly where the work is to be done. Two weeks after the work has started, the Design Build Team and the Project Engineer will again walk the project to assess the progress of the project.

19 BUILDABLE UNITS (BU)

Definition: Buildable Units are portions of the projects which can be designed, reviewed and built with only limited controls and assumptions coming from the design of other portions of the project. Often a Buildable Unit will be defined by a geographic area within the plan, but it may also be defined by types of work or construction stages which may require or permit similar, nearby work to be divided into separate Buildable Units. All Buildable Units shall summarize the materials required to construct that portion of the project. The summary shall include the Construction and Material Specifications Item Number, and a description of the materials to be used.

General: After the approval of the Preliminary Plan, DBT may break the project work into two or more separate BU which can be progressed through design and construction with minimal or known effect on each other and/or which can be dealt with sequentially such that sufficient data is available for design and review of each BU. In order that the design and construction of one BU may proceed without significant approved information from an associated BU, the DBT may develop and propose assumptions which will allow for the first BU to proceed through design and/or construction. These assumptions shall be submitted for review and comment but their accuracy and effort upon the final design are the sole responsibility of the DBT. Should error in these assumptions result in

additional work, remedial work or other changes to assure an acceptable design or should they result in the need to remove work and substitute additional work, the DBT shall be responsible for all such costs including, removal of unacceptable materials from the site, modification, additional work, repairs, etc. as necessary to produce an acceptable result.

If the DBT elects to develop Buildable Units, the DBT shall prepare, for review by the Department, a table of Buildable Units for the project with each BU described in detail.

If the table is approved, the DBT shall modify the Progress Schedule to show a separate group of activities for BU and these activities shall encompass all of the design and construction work in each BU. Work activities shall be further separated in the Progress Schedule to show a meaningful completion status (i.e. separate activities comprising the placement of a bridge deck on steel beams shall describe; shoring, form building, steel

(18)

slip forming parapets, provision of membranes, provision of wearing surfaces, curing, repair, form removal, cleaning, etc.)

The Final Review Submission and construction plans shall specifically be identified by the Buildable Unit code. If the design of a BU requires input information from an

adjacent or related BU, the source for that information in previously approved plans shall be cited or the DBT shall provide an estimated value of the data. The input data shall also be carefully identified. In the same way any assumption, calculations or results from the stage and BU which are used as input to another BU shall be similarly identified, and where appropriate, compared back to that BU to verify previous assumptions. Should assumptions not match values calculated later, the DBT shall re-analyze all affected components and determine appropriate changes. Should those elements have already been constructed, the DBT shall recommend repairs, adjustments, modifications or replacement of the existing work as necessary to comply with the Scope of Work. All costs for re-design, re-submissions, modifications, removals, disposal of materials and new work needed to remedy the project and bring it to compliance shall be borne by the DBT and no time extensions shall be approved for this.
