A SUMMARY.doe
IV. City Standard Materials
Some minor changes have been made throughout this section. Most changes are related
to requiring HDPE "plastic" adjustment rings and the frames to be bolted to the top of the
concrete structure on all sanitary sewer and forcemain structures as well as storm sewer
manholes within paved areas. This requirement changed frame and casting necessary for
these types of structures therefore the Neenah R-1642 frame and casting is required
instead of the R-1733. Core -blue or 316 Stainless Steel nuts, bolts, and threaded rods are
required for attaching these frames to the structures and all watermain fittings. The
following some additional changes;
12. IV.2.c, revised to include concrete cable and Flexamat as options at storm sewer
discharge points.
13. IV.2.h, added the following;
h. The last 3 pipe joints at all RC flared end sections on storm sewer pipe and
all RC Pipe culvert pipe joints shall be "tied" per MnDOT Standard Plate
14. IV.3.a, revised required sanitary sewer castings to Hamilton Kent Lifespan
System, Neenah R-1642 or approved equal. The old frame and casting (R-1733)
does not come with predrilled holes to anchor the frames to the top of the
manhole. Also revised the waterproof frame and casting to include the Neenah
R-1755-F2 (this was Otsego's previously approved waterproof casting ).
15. IV.3.d & IV.3.e added the following;
d. All frames for sanitary and forcemain manholes shall be sealed with
manufacture recommended adhesive to the top of the concrete structure or
adjustment ring(s) and bolted directly to the top of the concrete structure using
316 stainless steel nuts, bolts and/or threaded rods.
e. Final grade adjustments may be made by adding rings and raising
the frame or with metal casting inserts per the manufactures' requirements.
16. IV.4.h., Change Manhole Sealing section to the following;
h. Manhole Sealing
All existing and proposed sanitary sewer manholes shall be
watertight and receive a watertight frame and casting system. All
forcemain manholes and all gravity sanitary sewer manholes
within green spaces or within the 100 yr HWL area shall receive a
waterproof frame and casting system. All chimney areas (i.e.
adjustment rings) shall be externally sealed if locking "plastic"
adjustment rings are used or internally sealed where concrete
C:\Users\Tami\AppData\Local\Microsoft\Windows\Temporary Intemet Files\Content.Outlook\L723WOXW\EXHI13IT
A_SUMMARY.doc
adjustment rings are used. All joints 3' above the water table and
below shall be sealed. All seals shall be installed per the
manufactures specifications.
i. Standard Frame and Casting System
1. The standard watertight frame and casting system shall consist of Neenah
R-1642 system with cast iron frame, solid cast iron lid, cast iron extension
ring, HDPE "plastic" adjustment rings, and external chimney seal or;
2. Hamilton Kent, Life Span system with an elastomeric frame, elastomeric
extension ring, elastomeric adjustment risers, and cast iron locking lid.
Lid shall have (3) locking cam lugs, or approved equal.
ii. Waterproof Frame and Casting System
The waterproof frame and casting system shall consist of Neenah R-1755-
F2 system with cast iron frame, solid cast iron lid, & inner lid. Though
not typical if necessary HDPE "plastic" adjustment rings shall be used
with external chimney seals. The insert extension rings are not allowed for
final casting adjustments with these frames and castings or;
2. Hamilton Kent, Life Span system with an elastomeric frame, elastomeric
extension ring, elastomeric adjustment risers, and cast iron locking lid.
Lid shall have (3) locking cam lugs, or approved equal.
17. IV.4.h.ii, changed Sanitary Sewer Manhole Chimney Seal to allow external seals
as the manufactures of the HDPE plastic rings recommend the external chimney
seals when installing the HDPE rings. Added the following
IV.4.h.ii.I External chimney seal shall consist of an external EPDM
flexible rubber sleeve and a non -hardening butyl mastic adhesive.
(Manufacturer: Sealing Systems, Inc., External Infi-Shield Gator Wrap)
18. . IV.5.d, revised to ".... A stainless steel spring mounted frilly wrapped fiberglass
locator rod shall be attached to each hydrant...."
19. IV.5.j, added the following
IV.5 j All nuts, bolts, and rodding shall be high -strength, low -alloy steel and
shall be coated with a ceramic -filled, baked on fluorocarbon resin (i.e. Cor-
Blue Bolts) or shall be ASTM F 593 316 Stainless Steel in compliance with

i. When excavating, frozen dirt chunks should be separated from
non -frozen dirt. Frozen chunks shall not be placed back in utility
trenches or within the street subgrade.
ii. All excavations and utility trenches shall be backfilled each day to

ii. All manholes and valves shall be adjusted to the current finished
grade for access throughout the winter.
iii. Concrete doghouses, inverts, and grout between adjustment rings
(where allowed) shall have be not be allowed to freeze within the
first 72 hours. If streets are not to be finished prior to winter shut-
down, all concrete work except outside doghouses around pipes
may be finished in the spring
iv. Minimum cover shall be provided over all sanitary and water lines,
including forcemain, hydrants, services and all stubs. If no traffic
is allowed over the pipe 6' is sufficient for the winter otherwise in

A_SUMMARY.doe
be needed to end of cul-de-sacs and where future streets are sub -
cut and utilities are installed.

permits.
c. Streets (including concrete curb and gutter)
i. No frozen material shall be placed in the street subgrade or
aggregate base.
ii. New (unfrozen) material may be placed on a previous fully
compacted layer frozen layer.
iii. Curb and pavement cannot be placed on frozen ground. The
temperature shall be 36' and rising at time of placement.
Contractors may choose to place and compact extra material over
the area and peel off the frozen material just prior to placing curb
or paving. This frozen material shall not be used in the aggregate
base. Subgrade/aggregate base still needs to be toleranced prior
placing curb/pavement.
iv. A cold weather plan for placing concrete in cold weather shall be
submitted to engineer. Measures shall be taken to the concrete
does not freeze within the first 72 hours of placement. A method
to monitor maximum low temperatures in multiple places on the
concrete under cold weather protection shall be addressed. If a
section of curb is suspected of freezing, the concrete can be core
drilled in place and tested. Any frozen concrete shall be removed
and replaced.
v. Concrete samples shall cure overnight in same conditions as
concrete (i.e. under poly or under blankets, etc).

compliance with NPDES permit.
ii. If silt fence is damaged and cannot be repaired due to frozen
ground, bio-rolls or rock logs are an acceptable alternative.
iii. Inlet protection (i.e. Wimco's) shall be removed from catch basins
