Current through 2024-29, July 17, 2024
1.
General
Where other arrangements are not feasible, MaineDOT will
				  consider permitting attachment of Facilities on Highway Structures. Each such
				  attachment will be considered on an individual basis, and permission to attach
				  will not be considered as establishing a precedent for granting subsequent
				  requests for attachment. The following requirements are established for
				  attachment to any Highway Structure:
A.
P.E. License &
				Certification
A Maine Licensed Professional Engineer shall design all
				  proposals for attachments to Highway Structures in accordance with the latest
				  AASHTO standards. In the case of Bridges, each design proposal shall be fully
				  evaluated in accordance with the latest edition of AASHTO
LRFD Bridge
				  Design Specifications
and the Maine Department of Transportation
				  Bridge Design Guide (as applicable) to assess the effect of the attachment(s).
				  A statement certifying that the additional loading will not exceed allowable
				  limits is required as part of the design submittal.
B.
Out-of-Service Facilities
All Facilities that are taken out-of-service shall be removed
				  in accordance with Section
				  7(4),
Out-of-Service Facilities
.If any such Facilities are not
				  removed, MaineDOT may elect to remove such Facilities at the Authorized
				  Entity's expense.
C.
Other Applicable Permits
Authorized Entities are responsible for acquiring any and all
				  permits that may be applicable to their proposed work. Some of the applicable
				  permits may include:
(1)
Coast
				Guard Permits
A Coast Guard permit or notification may be required whenever
				  the proposed work will occur over a navigable waterway.
(2)
Railroad Permits
Work permits may be required for any work done over, under or
				  near a Railroad and are obtained directly from the Railroad Company.
(3)
Environmental
				Permits
Permits may be required by the
Natural Resources
				  Protection Act
(NRPA) administered through the Department of
				  Environmental Protection (DEP), Shoreland Zoning, Army Corps and others.
D.
Identification
				Tag
A permanent tag shall be affixed to each end of the attached
				  Facility identifying the Authorized Entity, the type of attachment, and a
				  contact telephone number. All tags shall be maintained in a legible condition
				  with current information.
E.
Communication and Electric Supply
				Lines
Communication and Electric Supply Lines shall be suitably
				  insulated, grounded, and carried in protective Conduit or pipe from the point
				  of attachment to the point of exit per applicable National Standards.
F.
Hazardous
				Transmittants
Mutually Hazardous Transmittants shall be isolated by
				  compartmentalizing or by auxiliary Encasement of incompatible carriers. This
				  shall include Electric Supply Lines, gas lines, effluent lines and sanitary
				  sewer lines.
G.
Casing Vents
Where a pipeline on or in a structure is encased, the Casing
				  shall be effectively opened or Vented at each end to prevent possible buildup
				  of pressure and to detect leakage of gases or fluids.
H.
Uncased Attachments
Where a Casing is not provided for a pipeline on or in a
				  structure, additional protective measures shall be taken, such as employing a
				  higher factor of safety in the design, construction and testing of the pipeline
				  than would normally be required for encased construction.
I.
Pipeline Shutoffs
Pipeline shutoffs, preferably automatic, shall be required
				  within close proximity of attachments unless other sectionalizing devices can
				  isolate segments of the lines. Shutoff valves shall be located on both sides of
				  a Highway Structure footing.
J.
Brackets/Bolt Material
For painted steel structures, all brackets and bolt material
				  in contact with the structure shall be hot-dipped galvanized. For weathering
				  steel (ASTM A588, A709, etc.), all brackets and bolt material shall also meet
				  an applicable ASTM weathering steel designation.
K.
Connection Type
All attachments shall be bolted. Bolt holes are normally
				  drilled 1/16inch larger than the bolt diameter. No stainless steel bolts shall
				  be used except on concrete or timber structures.
L.
Welding
Welding to steel components is not permitted.
