· 1499Ǧ1515 HilliardǦRome Road
The Contractor is required to manage PCS in accordance with the following:
·
·
·
April 2013
All excavations within the aforementioned limits shall be paid for under the
original plan bid items.
The Contractor shall provide the Engineer with ten (10) days’ notice prior to any
excavations within the aforementioned limits to permit arranging for the
necessary testing services.
All excavated materials generated from the properties listed above require
characterization by the Engineer. The Engineer will characterize the excavated
material and determine how the PCS will be handled, managed and disposed of.
The Engineer will provide the Contractor with the characterization laboratory test
results.
Page 11 of 32
All material excavated form the properties listed above may be stored in any of the
following ways provided the contractor develops and implements an acceptable
containment and storage plan to the engineer for approval:
o Temporary storage of the excavated material in a lined and covered roll-off box.
o On an impermeable membrane. The membrane shall be surrounded by bales of
straw to prevent the stockpiled materials from coming in contact with surrounding
soils. Place an impermeable membrane over the stockpile to prevent contact with
precipitation and/or surface run-off.
o Direct load the excavated contaminated material into trucks for disposal at an
appropriate facility.
The contractor is required to legally dispose of all regulated waste generated as a result of
the work. Disposal includes any required permits, approvals, or fees related to the
materials handled on the properties listed above. Any additional testing or
characterization required by the disposal facility is included in the items of work

ENVIRONMENTAL
The Department has obtained Environmental Clearance for this project. The complete
Categorical Exclusion is provided as Attachment R-3.
10.1
Waterway Permits:
The 404/401waterway permits for this project have yet to be authorized by the US Army
Corps of Engineers and/or the Ohio Environmental Protection Agency. The DBT shall
not perform any work in and/or place any fill in streams or wetlands until permits are
authorized by the US Army Corps of Engineers and the Ohio Environmental Protection
Agency. The permits will be provided to the DBT by ODOT as soon as they become
available. The DBT shall perform the work per the 404/401 permits including all special
conditions of the permits. Any work outside the limits covered under 404/401 permit
obtained by ODOT shall require additional permitting. Any additional permitting will be
the responsibility of the DBT to obtain.
As indicated in the Ecological Survey Report (Attachment R-4), there are two
jurisdictional ditches within the project area. These are indicated as Ditch 1 and Ditch 2.
It has been determined that the project should meet the requirements of the US Army
Corps of Engineers (USACE) Nationwide Permit Program due to the minor impacts to
Jurisdictional Ditch 1 at the southeast corner of Hilliard-Rome and Renner roads, as well
as Jurisdictional Ditch 2 at the northwest quadrant of the WB entrance ramp to I-70.
The environmental coordination and permitting for the project assumes that impacts to
Ditch 1 and Ditch 2 are limited to the amount of disturbance and fill necessary to replace
and/or extend the existing culverts to accommodate widened pavement. The remainder of
April 2013
Page 12 of 32
these ditches is assumed to remain in their current location and elevation. Therefore,
these ditches may not be relocated, filled, or excavated. Any work adjacent to the ditch
must not extend below the Ordinary High Water Mark (OHWM) of the ditch channel.
The OHWM can be calculated using the 2 year depth of flow in the stream as required by
Section 1105.6.13 of the L&D Manual.
It is required that the bidder be aware of Section 404/401 Permits/Certifications for all
projects impacting "waters of the US". The level of permit, that is Nationwide versus
Individual 404 and 401, is determined by the exact amount of impact to "waters of the
US", (i.e., acreage of fill activities in a stream or wetland or linear feet of work in a
stream) and in some cases the waters impacted. All individual 404 Permits require 401
Water Quality Certification. Nationwide Permits are activity specific permits used to
authorize projects with minor impacts. Projects with more than minor impacts require
individual review by the U.S. Army Corps of Engineers and the Ohio Environmental
Protection Agency.
The DBT should be aware of the Nationwide Permits and conditions as issued for the
State of Ohio and should design projects to meet the requirements of these permits to
avoid the requirements for Individual 404/401 Permits if possible. The Nationwide
Permits for the State of Ohio can be found at the various Corps of Engineers' web sites.
The Huntington District's web site can be found at: http://www.lrh.usace.army.mil/.
Coordination of the waterway permits can take up to nine (9) months for Individual
404/401 permits. Therefore it is imperative that the DBT submit plans (i.e., plan &
profile, cross-section and detail sheets for any bridges, culverts, or fill areas in waters) to
the District, for permit determination, as soon as possible. The review of plans, any
required coordination or the processing of permit applications must be accomplished by
the Office of Environmental Services prior to the commencement of construction
activities. The DBT shall be responsible for completing applications for 404 Permits and
401 Water Quality Certification, if they are required. At no time will the DBT coordinate
waterway permit issues directly with the permitting agencies unless directed to do so by
the Office of Environmental Services.
All Waterway Permit requirements are found in the Waterway Permits Manual.
10.2
National Pollutant Discharge Elimination System (NPDES) permit:
The DBT shall submit to the ODOT Project Manager the total number of acres of earth
disturbance activities for both off project and on project work in a timely manner. This
information will be used to develop the NOI if required. The NOI will be submitted to
the OEPA within 10 days after this information is received from the DBT. Approval from
the OEPA takes 21 days and the ODOT Project Manager has 10 days to file the NOI so
these 31 days will be counted for in the project.
All temporary erosion control is the responsibility of the Contractor even if a SWPPP is
not required. Earth disturbing activity is not permitted prior to the OEPA permit
April 2013
Page 13 of 32
approval. For projects that require an NOI, the SWPPP must be in place prior to the
initiation of any earth disturbing activity. All temporary erosion control work and the
SWPPP if required will be per SS832. For information about OEPA's NPDES permit
requirements see http://www.epa.state.oh.us/dsw/storm/index.html. Items used to
implement the DBT's Erosion Control requirements are paid from an encumbered amount
included in the proposal as a non-bid reference number. The proposal specifies the unit
prices for the erosion control items. Payments for erosion control items that exceed the
encumbered amount will be made by an Extra Work Change Order using the specified
unit prices. The specified unit prices are fixed for the contract and may not be negotiated
or adjusted for inflation or claimed changed condition.
10.3
Removal of Temporary Erosion Control Items
All temporary erosion control items shall be removed before the project is accepted.
Removed materials shall become the property of the Contractor and shall be disposed of
in accordance with the appropriate C&MS specifications.
10.4
ESA
The project is being implemented via design/build contracting method. The design/build
scope will include a plan note referring to the potential for encountering Petroleum
Contaminated Soil (PCS) during soil excavation in the vicinity of the Shell Gas Station
and car wash located at 1500 Hilliard Rome Road.
10.5
Other Resources, Drinking Water
The following plan note will be made to further protect drinking water wells:
This project is located near the Shell Gasoline Station at 1500 Hilliard Rome Road, the
St. James Lutheran Church at 5660 Trabue Road and the Perkins Restaurant at 1451
Hilliard Rome Road. In order to minimize the potential to contamination of these
drinking water resources project related refueling and maintenance activities shall not be
performed within the vicinity of these locations. The Contractor shall immediately take
steps to mitigate any event, such as a spill of fuels, oils, or chemicals, that could threaten
to contaminate the drinking water supply. If the spill is a reportable amount, the
Contractor should contact the Emergency Management Coordinator at the Franklin
County Emergency Management Agency at 614-794-0213 for cleanup of the spill.
10.6
Public Involvement
ODOT will issue a press release describing the initial phase (ramps) of the project.
ODOT will address all comments received with furtherance of project design and
development. Following the initial press release, ODOT will send an informational
mailing to the adjacent property owners or hold a Public Meeting to discuss the other
proposed improvements. ODOT and local officials will continue updating the public
throughout project duration.

contains inaccuracies which preclude a meaningful review, or does not adhere to the
Governing Regulations listed in section 8.1 of this document, the Department will advise
the DBT of the shortcomings and direct the DBT to revise and resubmit the plan. No
time extension will be granted as a result of such action. The Department will schedule a
review meeting or issue review comments as appropriate.
In the event the DBT believes that any review comment, or orders issued by the
Department, require a change to the scope of the agreed work, the DBT shall first contact
the Department for clarification and shall, within 10 days of receipt of the comments or
orders, provide written notice to the District Project Manager and Project Engineer
concerning the reasons why the DBT believes the scope has been changed.
18.3
Stage 1 Plan Review Submission: The DBT shall submit the Stage 1 detailed design
plan submissions as per Location & Design Manual, Volume 3 for review by ODOT.
These submission milestones must be shown on the Progress Schedule.

Unless indicated below, the Department shall have 21 calendar days from receipt to
review complete submissions. This review time must be shown on the required Progress
Schedule.
Following this review, the DBT shall correct any errors, incorporate modifications,
perform required investigations and make related changes to the plans and supporting
documents prior to submitting the plans for final review.
Plan Review Distribution: The DBT shall supply 4 half size (11" x 17") paper prints to
ODOT District 6 Project Engineer and to the parties indicated below. Each affected
utility company shall also receive one full size (22"x34") plans.
18.4
Major Design Decision: Separate submittals for concurrence with major design
decisions made after the Stage 1 Review are required. Major design decisions involve
significant utility relocation, unforeseen acquisition of ROW, traffic operation or
geometric decisions that involve two or more viable solutions, and any other decision that
impacts the public, operation of the facility or future maintenance.
When the DBT becomes aware of additional decisions during the course of the design,
they must advise the District Project Manager in writing.
18.5
Stage 2 Plan Review Submission: For each Buildable Unit the Consultant shall submit
Stage 2 detailed design plans as per Location & Design Manual, Volume 3 for review by
ODOT. All submissions must be shown on the required Progress Schedule.
The Department shall have 21 calendar days from receipt to review complete
submissions. This review time must be shown on the required Progress Schedule.
Following the review the Department will return to the DBT marked plans noted
‘ACCEPTED’, ‘ACCEPTED AS NOTED’ or ‘NOT ACCEPTED’ as described in
section 105.02 of the Construction and Material Specifications. The DBT shall correct
errors, incorporate changes, perform investigations and make related changes to the plans
and supporting documents prior to submitting construction plans.
Plan Review Distribution: The DBT shall supply 4 half size (11" x 17") paper prints to
ODOT District 6 Project Engineer and to the parties indicated below. Each affected
utility company shall also receive one full size (22"x34") plans.
18.6
Construction Plans: After the review comments for the final plan review submission
have been complied with, and following approval of the design documentation, the DBT
shall prepare plan sets for use during construction. All review comments shall be resolved
in writing by the DBT to the satisfaction of the Department before the DBT submits the
construction plans. Each plan sheet shall have its last revised date noted on the sheet and
clearly marked ‘Approved For Construction’. The ‘Approved For Construction’ plan set
shall be signed, dated and sealed by a Professional Engineer. Physical construction shall

not begin until the plans marked ‘Approved For Construction’ are delivered to each party
on the Plan Distribution Table below. No time extensions will be approved by the
District Construction Engineer if the plan distribution is not completed and project delays
occur as a result.

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: For the Stage 1 and Stage 2 submittals, the 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 Contractor 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
placement, placement of conduit & joints, pouring concrete, forming parapets, pouring or
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
April 2013
Page 30 of 32
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
Contractor and no time extensions shall be approved for this.
