within NDOT ROW as shown on the Drawings. The Work also includes supplying and installing a

new precast PCC valve vault with lid and H-20 rated aluminum access hatch and smart cover level

sensing system, as well as the supply and installation of a new 12-inch full port plug valve and bypass

line complete with 6-inch pressure relief valve and 6-inch isolation valves. The Work also includes

pressure testing the newly installed piping prior to connection. Final pressure testing of the system

after connections to the existing force main are in place will be accomplished through line working

pressure with two (2) of the existing DCSID effluent export pumps in operation.

B. Perform Work of Contract under executed Contract with Owner according to Conditions of

Contract.

1.3 CONTRACTOR'S USE OF SITE AND PREMISES

A. Limit use of Site and premises to allow:

1. Use of Site and premises by the public is limited to pedestrian, vehicular and cycling traffic

allow for all traffic to safely travel along Muller Lane at the Brockliss Slough and project

area during the course of construction.

2. The Parcel Owner of the property on which the Project is located may have cattle grazing

near the project. The Contractor shall be responsible for erecting and maintaining temporary

barriers (e.g. temporary barbed wire fencing) to prevent cattle from entering the project area

delineated on the plans.

commence dewatering of effluent force main to place of use for the temporary

discharge permit TNS-43521, identified as the Park Ranch West of the East Fork of the

Carson River.

1) OWNER will ensure force main line pressure is bled to 30 PSI or less.

2) OWNER will ensure that force main cannot receive new flow for duration of work.

Dewater the remaining portion of the effluent force main.

b. Drain residual effluent from force main, approximately 150,000± gallons, and dispose

of at DCSID approved location.

c. Perform intertie connections to existing sewer force main and install isolation valve and

bypass line.

d. Perform pressure test on complete installation under normal working pressure with two

existing export pumps in operation. Test the bypass line by temporarily closing the 12-

inch isolation valve.

B. Sequencing of Construction Plan: Before start of construction, submit electronic copy of

construction plan regarding phasing of force main relocation and all new Work, including

shutdowns, for review by ENGINEER and acceptance by OWNER. After acceptance of plan,

construction sequencing shall comply with accepted plan unless deviations are first reviewed by

ENGINEER and accepted by OWNER in writing.

1.5 OWNER OCCUPANCY

hours to determine leakage rate. Maintain pressure within plus or minus 5 psi of test

pressure. Leakage is defined as quantity of water supplied to piping necessary to maintain

test pressure during period of test.

L = SD x sqrt(P)/C

L = testing allowance, gph

S = length of pipe tested, feet

C = 148,000

When pipe under test contains sections of various diameters, calculate allowable leakage from sum of computed leakage for each size.

corrections, and retest until leakage is within allowable limits.

b. Correct visible leaks regardless of quantity of leakage.

E. Bypass Line Testing:

2017

1. Once connections to the existing force main have been fully constructed, Contractor shall

certify that they are operational and ready to be placed into service.

2. Coordinate with OWNER for placing force main back into service.

3. Owner will operate one (1) existing export pump to bring force main up to normal operating

pressures.

4. Once the force main is back in service and under pressure, perform visual leakage test in

presence of Engineer.

5. Any leakage of connections to existing force main will be considered failure of the test.

6. If failure of the leakage test occurs, Contractor shall repair or replace the connection until no

leakage occurs.

3.5 PROTECTION

A. Section 01 70 00 - Execution and Closeout Requirements: Requirements for protecting finished

Work.

B. Protect pipe and aggregate cover from damage or displacement until backfilling operation is in

progress.
