CHANGE ORDER No. 1
DATE OF ISSUANCE: 02/16/12 EFFECTIVE DATE:
OWNER: BCRUA
PROJECT: 78-Inch Treated Water Transmission Line Segment One Construction Phase Services
ENGINEER: Lockwood,Andrews, and Newnam, Inc.
The Engineer is hereby directed to make the following changes in the Contract:
1. Continued construction phase services
ADD OR DEDUCT$40,000.00
TOTAL(Items 1 -2) ADD OR DEDUCT$ 40,000.00
NOTE: This Change Order increases the Not To Exceed Amount of LAN's Construction Phase Services Contract.
It does not increase the scope of work nor the time. The increase in the NTE amount is due to the
additional engineering work to resolve the Gann Ranch Tunnel Grout issue. The cost of this engineering
work is expected to be reimbursed to BCRUA by the construction contractor. All work under this contract
remains Time and Materials. However, due to this additional work - the current NTE amount may be exceed
by LAN as reflected in their current contract; consequently BCRUA needs to increase the NTE amount of
the Contract even though BCRUA will be reimbursed for this additional work caused by the construction
contractor error. Recommend DOC and GM approval.

RE: Treated Transmission Main Segment 1
SA3 —Additional Construction Phase Services for Contractor Variances
Mr. Thuss:
The above referenced project has experienced two distinct issues that have caused LAN to perform
above outside our initial scope of services for construction phase. These issues are described
below:
Cathodic Protection System.
Initial Field Testing of the CP system and subsequent CP report did not provide adequate
information to verify the CP system was functioning and providing Cathodic Protection as defined
by the NACE Standards. Initial testing did reveal that the liner at Lakeline was shorted to the
carrier pipe. Due to the inadequate or ambiguous data, a second round of field testing was
performed. This testing confirmed that the liner is shorted to the carrier pipe. The Contractor
performed additional testing and provided a proposed resolution to the shorted casing. LAN/V&A
approved the proposed resolution in concept, however, we did identify what appeared to be a
calculation error which impacted the number and size of additional anodes needed. Our
recommendation to SJ Louis was to verify Corrpro's design, revise as required and proceed with the
proposed solution, with the understanding that final testing would be required to verify the
additional anodes are providing adequate CP per NACE standards.
Items that are considered additional effort include:
1. Second round of field testing—This was required because SJ Louis/Corrpro did not provide the
adequate test data during the first field testing to verify cathode protection. In addition,they
performed much of the testing prior to V&A's arrival.
2. Review of 2 proposed resolution for shorted casing.
3. Anticipated third round of field testing to verify cathodic protection of shorted casing
Gann Ranch Tunnel Grout Issue.
After confirming that the annular grout installed at the Gann Ranch tunnel was deficient, LAN and
Brierley reviewed the liner design and existing soil conditions and provided an opinion regarding
the potential for settlement and failure of the roadway due to the deficient grout. Mitigation
options were developed and estimated costs associated with the mitigation provided. LAN
coordinated with COCP and BCRUA to determine the acceptable mitigation. Upon receipt of the
Contractor's formal response to the deficiency, LAN prepared a response and recommended
monetary restitution in an amount equal to 1) Additional Engineering Costs and 2) Estimated Cost
of the acceptable mitigation as determined by BCRUA and COCP. Currently the Contractor is
performing their own analysis and it is anticipated they will provide an alternative resolution. All
effort associated with this issue is considered additional effort.

We estimate that the additional cost to date for these variances is approximately $33,000. Based
on these additional efforts and anticipated effort remaining, LAN is requesting an additional
$40,000, time and materials not to exceed, to see these issues through their conclusion.
Please contact me at (512) 338-4212 if you have any questions regarding this request.
