Lake Oswego/Tigard Water Supply Partnership

TO: Oversight Committee FROM: Joel B. Komarek, P.E., Project Director Technical Committee DATE: January 7, 2016 SUBJECT: Waluga Reservoir No. 1 – Roof Replacement

PURPOSE

The purpose of this memorandum is to:

1. Summarize the findings, conclusions and recommendations from a report prepared by Peterson Structural Engineers, Inc. (PSE) relating to a recent inspection, condition assessment, and seismic evaluation of an existing 4 million gallon (MG) concrete water storage reservoir (“WR1”).

2. Discuss how WR1 operates in tandem with the Partnerships new water storage reservoir (“WR2”).

3. Discuss why WR1 is a beneficial water supply asset to Tigard.

4. Recommend an approach and schedule for replacement of the roof on WR1.

BACKGROUND

The Waluga Reservoir No. 1 was constructed for the City of Lake Oswego between 1980 – 1982. The reservoir is approximately 190-feet in diameter and 21-feet tall and stores approximately 4 MG of potable water when full. The reservoir type is known typically as a circular, wire-wrapped, pre-stressed concrete tank. Hundreds, if not thousands, of these style tanks are in service throughout the US and abroad. Standards for design of these types of tanks are published in the American Water Works Association (AWWA) Manual D-110.

WR1 is the City’s “terminal” reservoir for the water distribution system north of Oswego Lake. Water supply from the City’s water treatment plant to the north side of Oswego Lake passes through WR1 first before being pumped to other higher reservoirs within the City’s distribution system. Since its construction in 1982, surplus water provided to Tigard flows first through WR1.

In 2013, after design for the new WR2 had begun, the City commissioned an inspection of the interior of WR1 while in service by means of a scuba diver with a video camera. The underwater inspection revealed concrete delamination from the underside of the reservoir roof and exposed, corroded rebar.

Memorandum Oversight Committee P a g e | 2

The inspection also revealed severe corrosion on internal metal structures (e.g., access ladder, overflow pipe and supports, etc.). As a result, in 2013, the City amended the design contract for WR2 to include design of a new access hatch, access ladder, overflow pipe and mixing manifold for WR1.

In 2015, construction of WR2 was completed and put into service. As planned, WR1 was then completely drained to allow a thorough and comprehensive inspection and condition assessment of the tank and to make modifications to the tank. Structural engineers from PSE conducted their examination of WR1 on 6/5/15 and then again on 6/23/15. Findings, conclusions and recommendations from PSE regarding WR1 are summarized below:

Interior/exterior walls and floor slab – PSE concludes the condition of the core wall (interior/exterior surfaces) and floor slab are generally in good condition with no apparent leaks or cracks that would cause concern.

Roof support columns – PSE concludes the slender, square columns are generally in good condition, except for several observed defects which are likely the result of poor concrete form work and inadequate inspection. PSE opines these defects do not appear to have significantly compromised the stability of the roof.

Roof – PSE concludes that construction related defects and inadequate or poorly placed reinforcing in the roof slab have resulted in observed deformation of the roof slab, particularly at the supporting columns. Structural analysis of the roof structure as designed and constructed, reveals “…the existing roof slab analytically fails in almost all respects of its capacity.”

PSE concludes their report with the following statement:

“Our visual observations and structural analysis reveals the water bearing elements (floor and wall) of the existing 4.0MG reservoir are in fairly good condition and should continue to serve the City well for decades to come under all currently expected loading conditions. However, the roof system we believe represents a significant vulnerability and should be addressed as soon as is reasonably possible. We feel that if the recommended repairs are made and the reservoir continues to be maintained, the City can expect the reservoir system to remain a functional structure for a period exceeding 50-years.”

DISCUSSION

The Partnership Intergovernmental Agreement (“Agreement”) obligates Tigard to “purchase” its allocable share of Lake Oswego’s existing water supply system assets to the extent such assets have excess capacity useful in supplying water to Tigard. Exhibit 1 to the Agreement documents the valuation of those assets as of 2008 and identifies which of the assets are beneficial to Tigard and thus subject to the buy-in provisions of the Agreement (see Article IV). Those assets are enumerated in Exhibit 6 of the Agreement (as amended), and for convenience, are repeated below:

Land and easements owned by Lake Oswego and located at the river intake pump station, water treatment plant, and Waluga reservoir site.

Raw water pipeline.

At the time of the initial valuation and buy-in (2008-2009) no other water system assets owned by Lake Oswego (e.g., WR1, WTP RIPS) had excess capacity to serve Tigard, and so were not subject to the buy-in provisions of Article IV.

The design of WR2 includes a complex system of on-site piping and valving that allows both WR1 and the new WR2 to operate together, or individually should there be a need to temporarily remove WR1 or


WR2 from service. In normal service mode, water from the WTP flows into WR2 first before flowing into WR1 where it can then be withdrawn for supply to Tigard’s new Bonita Pump Station (BPS). With WR1 out of service, Tigard supply is met through WR2. Within the next few months, WR2 will be temporarily drained to facilitate repair of a small crack and during this time water stored in WR1 will be made available to Tigard. During replacement of the WR1 roof, supply to Tigard will occur through WR2. The duration of the construction for a new roof on WR1 is estimated to be 6 months.

Because of the critical function these two reservoirs provide to the Partnership in terms of capacity and operational redundancy, staff believe that the existing WR1 should be considered a mutually beneficial asset owned by the partner cities and costs for the planned roof replacement should be shared. The fact that WR1 is the facility supplying water to Tigard in normal operating mode or the source of supply when WR2 is offline was the basis for staff’s conclusion that a cost sharing arrangement for the repair of the roof was appropriate.

APPROACH TO ROOF REPLACEMENT

Design Services – The design firm Black & Veatch (BV) was retained through a competitive qualifications based selection process (QBS) to provide reservoir design services for WR2 and subsequently for design of improvements to WR1. Legal counsel for Lake Oswego has advised that amending BV’s existing design contract to include design of the new roof will comply with state and City public contracting rules, subject to the development of written findings supporting this approach.1

Land Use - The City’s planning department has advised that replacement of the reservoir roof would be subject to land use review/approval as a minor development. Any change to the roof geometry, removal of trees, or painting of the existing tank would also require modifications to prior land use approvals.

Construction – Over the next six months certain program activities including crack repair on WR2 and commissioning of the new filters at the WTP in April/May will restrict the City’s ability to take WR1 offline for roof replacement until after the 2016 peak summer supply season. Staff proposes to complete the design, secure land use approvals, develop construction documents and solicit competitive proposals from qualified contractors beginning early August 2016. A notice to proceed with construction would then follow in October. A six month duration extends the completion date to April 2017.

IGA Amendment – Staff recommends the existing Agreement and exhibits 1, 6, and 7 be amended to reflect the inclusion of WR1 into the Partnerships shared facilities mix. Whether Tigard contributes an additional “buy-in” amount toward the depreciated replacement value of WR1 in addition to sharing the cost for the roof repair, is a matter to be discussed by the OVC and their respective councils.

SUMMARY AND RECOMMENDATIONS

The existing WR1 has provided reliable, economical water storage service since 1982. Recent modifications made to this reservoir provided a unique opportunity to conduct a thorough investigation of the construction of the tank. The investigators observed construction defects in the tank roof and supporting columns, but believe the tank walls and floor to be in good condition and capable of continued service “…under all currently expected loading conditions.”

To provide redundant and reliable water storage for supply to Lake Oswego and Tigard, design of the new WR2 included a complex system of piping and valves that allow supply to Tigard to be maintained when WR1 or WR2 are out of service. This aspect of the WR2 design was not contemplated in 2008

1 See written findings attached as Exhibit ‘A’.


when the Agreement was created and entered into by the two cities, but is a reality today. Staff from both cities believe this reality justifies the inclusion of WR1 into the shared facilities mix for the Partnership and the sharing of costs for the roof replacement.

Based on the foregoing information, staff recommends the OVC:

Review and discuss this memorandum at the upcoming meeting.

Authorize staff to proceed with the design and land use permitting process.

Authorize staff to prepare documents necessary to amend the Agreement and specifically Exhibits 1, 6, and 7 to include WR1 in the Partnerships supply facilities.

Make recommendations to your respective councils supporting the proposed approach to replacing the reservoir roof.

Staff look forward to discussing this matter further with you at the upcoming January 11 meeting. In the meantime, if you have any questions, please feel free to contact me.

Findings in support of an amendment to a personal services contract with Black and Veatch Corporation for engineering services relating to construction of a new roof on the Waluga Reservoir No. 1 for the Lake Oswego-Tigard Water Partnership.

FINDINGS FOR AN AMENDMENT TO A PERSONAL SERVICES CONTRACT WITH BLACK AND VEATCH CORPORATION FOR ENGINEERING SERVICES RELATING TO CONSTRUCTION OF A NEW ROOF ON THE

WALUGA RESERVOIR NO. 1 FOR THE LAKE OSWEGO-TIGARD WATER PARTNERSHIP WHEREAS, the cities of Lake Oswego and Tigard, pursuant to an Intergovernmental Cooperative Agreement (“Agreement”), are undertaking the planning, design, funding, and construction of improvements and upgrades to Lake Oswego’s water supply system that includes the design and construction of a new reinforced concrete water storage reservoir; and WHEREAS, the Agreement establishes the City of Lake Oswego (“City”) as the managing partner and delegates all contracting authority to the City for procurement of contracts for design and construction of the water supply improvements; and WHEREAS, pursuant to its delegated contracting authority and in accordance with Lake Oswego Public Contract Rule 102-0277, the City initiated a formal competitive proposal process to contract for engineering services for design and construction of a new concrete water storage reservoir (“Waluga Reservoir #2, WR2”); and WHEREAS, on September 6, 2011, the City contracted with Black and Veatch Corporation (“BV”) to provide design services and engineering services during construction for the planned new WR2; and WHEREAS, in April 2013, the original contract with BV was amended to include design and construction services for modifications to the City’s existing water storage reservoir (WR1), located immediately next to the planned new WR2; and WHEREAS, OAR 137-048-0200 authorizes the City Council of the City of Lake Oswego acting as the Lake Oswego Contract Review Board, to enter into a new public contract or contract amendment of an existing contract without initiating a new formal selection procedure if:

“….(A) The services consist of or are related to Architectural, Engineering, Photogrammetric Mapping, Transportation Planning or Land Surveying Services or Related Services that have been substantially described, planned or otherwise previously studied under an earlier Contract with the same Consultant and are rendered for the same Project as the Architectural, Engineering, Photogrammetric Mapping, Transportation Planning or Land Surveying Services or Related Services rendered under the earlier Contract;

(B) The Contracting Agency used either the formal selection procedure under OAR 137-048-0220 (Formal Selection Procedure) or the formal selection procedure applicable to selection of the Consultant at the time of original selection to select the Consultant for the earlier Contract; and

(C) The Contracting Agency makes written findings that entering into a Contract with the Consultant, whether in the form of an amendment to an existing Contract or a separate Contract for the additional scope of services, will:

(i) Promote efficient use of public funds and resources and result in substantial cost savings to the Contracting Agency; and,

________________ Page 2


(ii) Protect the integrity of the Public Contracting process and the competitive nature of the Procurement by not encouraging favoritism or substantially diminishing competition in the award of the Contract.”; and

WHEREAS, the Project Director for the Partnership has determined that the conditions described in OAR 137-048-0200(1)(d)(A)(B) above, are present and that the public interest is best served by making findings supporting an amendment to BV’s existing contract.

NOW, THEREFORE, THE PROJECT DIRECTOR OF THE CITY OF LAKE OSWEGO MAKES THE FOLLOWING FINDINGS IN SUPPORT OF AN AMENDMENT TO A PERSONAL SERVICES CONTRACT WITH BLACK AND VEATCH CORPORATION FOR ENGINEERING SERVICES RELATING TO CONSTRUCTION OF A NEW ROOF ON THE WALUGA RESERVOIR NO. 1 FOR THE LAKE OSWEGO-TIGARD WATER PARTNERSHIP

A. OAR 137-048-0200(1)(d)(C)(i) - Promote efficient use of public funds and resources and result in substantial cost savings to the Contracting Agency.

Findings:

a. Through the design, permitting, and construction of WR2 and related improvements to WR1, BV has developed an extensive knowledge of the City’s land use procedures, design standards, accounting procedures and document control systems and procedures as they relate to the design and construction of water supply and storage facilities for the Partnership.

b. It is unlikely that through a new formal solicitation of proposals, the City would receive responses from another firm possessing an equivalent body of local knowledge, expertise, and experience relating to reservoir design and construction in the City than that possessed by BV.

c. Avoiding a new formal selection procedure eliminates costs associated with such an undertaking and costs associated with “training” a new consultant in the standards and procedures adopted by the Partnership for the design and construction of supply facilities. Based on past similar efforts, the estimated cost to undertake a new formal selection procedure range from$25,000 to $50,000.

d. BV is currently under contract and can immediately mobilize to begin the design and land use permitting phase for the WR1 roof replacement. Undertaking a new formal selection procedure and entering into a contract with a different consultant would take approximately three months to complete. Such a delay in initiating the design would necessarily delay the land use permitting process and replacement of the roof.

B. OAR 137-048-0200(1)(d)(C)(ii) - Protect the integrity of the Public Contracting process and the competitive nature of the Procurement by not encouraging favoritism or substantially diminishing competition in the award of the Contract.

Findings:

a. The total budget for engineering design services and related engineering services during construction across the program is approximately $24,707,000. The estimated range of fees for design and services during construction relating to WR1 roof replacement is expected to

________________ Page 3


range from $175,000 to $250,000 representing approximately 0.7% to 1% of total design contract costs.

b. In response to a request for proposals for design services related to WR2, the City received two proposals from well-known local design firms. It is believed the response to the solicitation was due in large part to the fact that several local and national design firms had keener interest in competing for much larger design contracts for the water treatment plant and pipelines. Based on this prior outcome, the Project Director finds that the relatively small dollar value estimated for the roof replacement design work will likely not generate substantially more competition for the design contract than would have been generated had the roof replacement work been part of the original design scope of services.
