INTRODUCTION The HDPE End Cap study resulted in the identification of five turnout locations with end caps that may experience similar failures to the T30 and T36 turnouts. These locations have 30-inch or larger end caps which could be modified or eliminated to mitigate risk of failure. The turnout facilities are identified with in the content of this report. The duration of mitigation measure implementation is expected to take approximately 216 calendar days for each location including design, material procurement, site preparation, and retrofit construction. The actual construction period may fit within the off-season (July through August) so a variance should not be required. Given the scale of the work, it likely would need to be spread over a number of years to complete, logically beginning with the turnout structures identified as having the highest risk.

T10 Turnout Facility Budget and Schedule BACKGROUND DISCUSSION The T10 Turnout Facility was originally installed as a part of the Phase 7 construction project (Year 2010). The turnout 36-inch inlet end cap is located 5 feet from the edge and 5 feet below grade. The 30-inch outlet end cap is located 7 feet from the edge and 12 feet below grade.

Location of the T10 Turnout Facility

PURPOSE 1. To implement measures to reduce the potential for end cap failures. 2. To implement measures to reduce the damage resulting from an end cap

failure.

SPECIFIC TASKS AND DURATION The total project duration (216 calendar days): • Design (24 calendar days): The tasks include:

1. Safety review of engineering plans and field location – 7 calendar days. 2. Engineered shoring plans for the trench located adjacent to the end cap –10

calendar days. 3. Completion of the revised as built plans – 7 calendar days.

• Materials Procurement (126 calendar days): The tasks include: 1. The purchase and delivery of pipe, fittings, and valves – 126 calendar days.

• Pre-Construction (17 calendar days): The tasks include: 1. Review of operational schedules for the turnout facility – 3 calendar days. 2. Preparation of the environmental control measures for construction activities –

14 calendar days. • Construction (49 calendar days): The tasks include:

1. Site preparation for construction activities. The preparations include access for construction equipment and material storage area - 21 calendar days. 2. The modification of the existing end cap. The activities include the trenching,

8

modification of the existing end cap and burial of the modified end cap – 28 calendar days.

IDENTIFICATION OF MITIGATION MEASURES

The measures are: 1. Replace the existing 30 inch end cap with a 30 inch by 24 inch reducer, 24

inch butterfly valve, 50 feet of 24 inch HDPE pipe extended into the lake bed, and a 24 inch end cap. Install the 24 inch isolation valve upstream of the end cap and adjacent to the pad. The advantages of the isolation valve are:

a. Allow the quick shut down of the water supply pipe to the end cap upon failure.

b. The use of this valve will allow the turnout to continue normal operations.

c. The repair of the end cap will be scheduled at a time convenient to the repair crew.

2. Install an air/vacuum valve adjacent to the end cap to mitigate the impact of pressure spikes on the end cap.

3. Encase the end cap in concrete. 4. Restrain the end cap with concrete (thrust block). A thrust block transfers the

resultant thrust force to the undisturbed soil adjacent to the thrust block. The result is the undisturbed soil will absorb the thrust force instead of the end cap.

5. Vertically raise the end cap to three feet above grade with a 30 inch by 24 inch reducers, 24 inch 90 degree elbow, 24 inch straight pipe, 45 degree elbow, and 24 inch end cap. The purpose of the end cap relocation is so that when the end cap fails; the resulting force of water is directed away and will not undermine the existing pad.

a. The pond and shallow flood area are required to be dry prior to construction.

The adjacent pond or shallow flood may require up to 30 days for dry down. b. The water table depth ranges from 4 to 12 feet below grade. Drainage pumps will

be required. c. Excavation is required to access the end cap. The fusion machine will require an

additional 4 feet of excavation. The total excavation required to access the end cap is 22.0 feet. Shoring is required at depths greater than 5 feet below grade.

d. The environmental temperature range of 0 F – 120 F throughout the year.

CONCLUSIONS & RECOMMENDATIONS

a. To proceed with the mitigation measures as listed.

b. Proceed with a request for a variance will be required for dust mitigation during the construction phase. Variance may be required: 1. To initiate dry down 30 days prior to construction (for a July date, the dry down may be required to begin in June). 2. To initiate a delayed pond fill post construction, (for an August date, the pond fill may be required to start in September). The pond may

not be in compliance by the October date. Based on the construction activity to occur in the cooler portion of the year: estimated evaporation rate of 50% or 3.0 feet. The recommended project schedule month will be October 2013. The estimated cost savings based on not providing water for the areas under construction for the one month time period is: 1. Area = 1,609 acres 2. Evaporation rate = 3.0 feet/year or 0.25 feet for October 3. Cost of water = $847/acre- foot 4. Total cost = $241,833 (1,609 acres x $847 acre foot x 0.25 feet) 5. The net cost to the department is $15,705 in funding ($340,705 -

$325,000).

T18 Turnout Facility Budget and Schedule BACKGROUND DISCUSSION

On Thursday, January 29, 2009 at 2:00 p.m., the T18 turnout facility 30- inch end cap experience a catastrophic failure. The 30-inch end cap was buried in the lake bed


Turnout Station 18 Overview

32

The damage caused by the end cap failure was insignificant. When the 30- inch end cap failed, the water flow was discharged on to the lake bed. The end cap was repaired in place and the turnout was returned to service.

PURPOSE

1. To implement measures to reduce the potential for end cap failures. 2. To implement measures to reduce the damage resulting from an end cap

failure.







1. Site preparation for construction activities. The preparations include access for the construction equipment and material storage area - 21 calendar days. 2. The modification of the existing end cap. The activities include the trenching,

The modification of the existing end cap, and burial of the modified end cap – 28 calendar days.


The measures are: 1. Install an air/vacuum valve adjacent to the end cap to mitigate the impact of

pressure spikes on the end cap. 2. Encase the end cap in concrete. 3. Restrain the end cap with concrete (thrust block). A thrust block transfers the


4. Install a 30 inch isolation valve upstream of the end cap and adjacent to the pad. Recommend the use of line stopping equipment for the installation of the valve (http://www.adsenv.com/default.aspx?id=378 ). The advantages of the isolation valve are:


b. The use of this valve will allow the turnout to continue normal operation.

CONSTRUCTION CONSIDERATIONS The end cap is located on the inlet side of the turnout facility. The cap is 8 feet west and 36 feet (in the lake bed) south of the edge of the pad and 5.0 feet below grade.

m. The pond and shallow flood area are required to be dry prior to construction.

Depending on the location of the turnout, the adjacent pond or shallow flood may require up to 90 days for dry down.

n. The water table depth ranges from 4 to 12 feet below grade. Drainage pumps will be required.

o. Excavation is required to access the end cap. The fusion machine will require an additional 4 feet of excavation. The total exaction required to access the end cap is 15.1 feet. Shoring is required at depths greater than 5 feet below grade.

p. The environmental temperature range of 0 F – 120 F throughout the year.


a. To proceed with the mitigation measures as listed. e. Proceed with a request for a variance will be required for dust mitigation during

the construction phase. Variance may be required: 1. To initiate dry down 30 to 60 days prior to construction (for a July date, the dry down may be required to begin in April). 2. To initiate a delayed pond fill post construction, (for an August date, the pond fill may be required to start in September). The pond may

not be in compliance by the October date. Based on the construction activity to occur in the cooler portion of the year: estimated evaporation rate of 50% or 3.0 feet. The recommended project schedule month will be October 2013. The estimated cost savings based on not providing water for the areas under construction for the one month time period is: 16. Area = 2,046 acres 17. Evaporation rate = 3.0 feet/year or 0.25 feet for October 18. Cost of water = $847/acre- foot 19. Total cost = $433,240
