PRESENTERS

Tom Frys, P.E. – Project Manager Monroe County Dept. of Transportation

Mark Laistner, P.E. – Dir. of Bridge Design Popli Design Group


CULVERT CHARACTERISTICS

• Located in the Town of Greece • Collector Road w/8,862 ADT • Built in 1982 (I-390 project) • Twin 78” Diameter C.M.P. • 220’ Length (end to end) • Drainage Area: 2530 Acres/3.95 Sq. Miles • Height of Cover: 23’

PROBLEM DISCOVERED


Upstream debris catcher


Debris at inlet


April 2015 – debris removed


Collapse in west pipe (span 1) inlet side, outside of roadway


RESPONSE


We used our term service agreement to bring in a contractor to do an emergency temporary repair.


Excavation of soil over collapsed area


Temporary cofferdam in place


Soil being removed from above


72” x 25’ long diameter steel pipe being installed


Completed temporary repair


LONG TERM SOLUTION

• Monroe County had concerns about another failure occurring under the roadway or sidewalk and the resulting lack of hydraulic capacity.

• Using our term services agreement, we

brought in Popli Design Group to design a permanent solution.


BASICS OF CULVERT LINING


CULVERT LINING ALTERNATIVES

• Paving invert with concrete • Lining with Shotcrete • Lining with cured in place pipe (CIPP) • Lining with new pipe


BENEFITS OF CULVERT LINING

• Cost effective for deeply buried culverts • Structurally redundant (pipe within pipe) • Can be done without closing the road


CHALLENGES OF CULVERT LINING

• Hydraulic opening is reduced (higher velocity) • Installation difficulties (fit & grouting) • Environmental (no natural bottom)

•


PRELIMINARY ENGINEERING


FIELD INSPECTION

• Verified condition of pipes • Verified pipe geometry (length, diameter, slope) • Documented pipe deformations • Documented any obvious voids (location, size) • Verified end conditions (headwalls, scour)

•


Gap between pipe sections


Pipe deformation at joint (beginning to fail)


Pipe section corroded to the point of failure


Culvert inlet


Culvert outlet (concrete apron w/ energy dissipater)


Laser scanning of culvert interior


Laser scanning of culvert interior


HYDRAULIC ANALYSIS

• Culvert is not in a mapped flood hazard area • Compared existing/proposed performance • Used flows from previous drainage study • Used HY-8 culvert analysis program


HYDRAULIC ANALYSIS

• Existing 78” CMP (pipe roughness, n = 0.026) • Proposed 66” I.D. smooth HDPE profile wall pipe

(n = 0.013) w/ beveled inlet headwall • Q50 backwater level was slightly lower • Q50 outlet velocity increased from 13 fps to 15 fps


REHABILITATION DESIGN


CULVERT LINING SPECIFICATION

• NYSDOT Item 602.2766 (Lining with profile wall HDPE pipe - 66”) • Pipe material: NYSDOT 706-11 (ASTM F894) • Grout: designed by contractor


CULVERT LINING SPECIFICATION

• 1-inch annular grout space is required between the host and liner pipes

• Proposed installation procedure must be submitted for review

• A note on plans required all joints to be welded

PERMITTING


PERMITTING

• A NYSDEC Permit was not required • USACE Nationwide Permit #3 – Maintenance • PCN was required – submitted to USACE • Blanket water quality certification does not

apply to culvert lining projects – NYSDEC review was needed


PERMITTING • The agencies had concerns with culvert lining

as a rehabilitation technique • They had concerns related to the passage of

aquatic organisms through the culvert • They also preferred to have a natural bottom

in the culvert • Permit authorization was eventually obtained

by persistent communications with the permitting agencies


BIDDING

• Monroe County bid the purchase of the pipe and installation separately to save time. Pipe Supplier: ISCO Industries $ 76,337 Pipe Installation: Skanex Pipe Services $257,700 Total Cost $334,037 Engineer’s Estimate: $314,220


CONSTRUCTION


LINER PIPE INSTALLATION


Liner pipe arrives in 50-ft lengths


Liner pipe storage area


Profile pipe ends not square due to spiral construction


Moving pipe down the embankment


Moving pipe down the embankment


Liner being inserted into Span 2


Fusion welder


Beveling joint for welding


Welding outside of pipe


Welding inside of pipe


Welding at jog in spiral end


Removing temporary repair pipe






GROUTING


Grout bulkhead with grout and vent tubes


HDPE bulkhead for flooding pipe to weigh it down


Pump and foaming equipment for cellular grout


Verifying unit weight of cellular grout (38 lb/ft3)


Pumping in grout


HDPE bulkhead failure


Bulkhead repaired and grouting completed


Inspection holes were made in the grout bulkheads


Void found at Span 2 outlet


Void found at Span 2 outlet


Finishing pipe ends to proper bevel


Finished project


LESSONS LEARNED • The lining spec. allows various pipe wall

thicknesses & joint types – this can affect pipe fit

• Bidding the pipe and installation separately created coordination issues

• USACOE and NYSDEC have concerns with culvert lining – be prepared to defend your design

• Each contractor may do things differently – the work procedure submittal is critical

PDH QUESTIONS


Q: True or false? Culvert lining is an

appropriate rehabilitation method for culverts under large amounts of fill.

A: True.


Q: What type of liner was used on the

English Road culvert rehabilitation?

A: HDPE profile wall pipe.


Q: What type of grout was used on the

English Road culvert rehabilitation?

A: Cellular grout.


Q: What was the unit weight of the cellular

grout?

A: 38 lb/ft3.
