FOR ENGINEERING SERVICES FOR THE WING PARK SWIMMING POOL BE IT RESOLVED BY THE CITY COUNCIL OF THE CITY OF ELGIN, ILLINOIS, that Robert O. Malm, Acting City Manager, be and is hereby authorized and directed to accept the proposal on behalf of the City of Elgin of Donohue & Associates, Inc. for engineering services for the Wing Park Swimming Pool, a copy of which is attached hereto and made a part hereof by reference. Richard L. Verbic, Mayor Presented: October 8, 1984 Adopted: Vote: Yeas Nays Recorded: Attest: Marie Yearman, City Clerk :() Donohue May 8, 1984 Mr. Melford A. Dahl, P.E. Director of Public Works City Engineer City of Elgin 150 Dexter Court Elgin, IL 60120 Re: Wing Park Swimming Pool Dear Mr. Dahl: This letter is a follow-up to our April 24, 1984 meeting during which we discussed and visited the referenced pool. The purpose of this letter is to present ideas on how the City could systematically approach investigation and possible resolution of the pool problems. We understand the City's immediate concern with the pool is the difficulty of emptying, cleaning and painting the deep end because of continuous flow of water into the pool through a construction joint. Other potential problems include loss of soil from beneath the pool at the leaking joint and insta- bility caused by high hydrostatic uplift when the pool is temporarily emptied in the spring for cleaning and painting. We suggest a phased approach, as described below, for analyzing and possibly solving the pool problems. With the exception of the first phase, each phase would be undertaken only if warranted based on one or more of the preceding phases. Any of the phases could be further broken down into additional phases for contract purposes. PHASE I: RECONNAISSANCE Tasks: 1. Review pool plans, supporting documentation, and other relevant data in City files. If necessary, contact the pool designer for additional information. 2. Perform a site reconnaissance. A structural engineer and a groundwater scientist will examine the pool and surrounding areas. Examples of points of interest include: topography and site drainage; surface soil types; overall condition of the structure including indications of faulting or other movement; the nature of the troublesome construction joint; possible loss of soil material from beneath the pool, particularly at the structural joint; pressure and condition of relief valves; plumbing and possible location of bore holes and observation wells. Our proposal assumes that City personnel will be available to gain access to the site, dewater the pool, and provide relevant data and information.

Perform preliminary calculations, based on readily available information and stated assumptions, of the relative magnitude of upward and downward forces on the pool to determine the potential for damaging uplift. Timing: Phase I could be carried out on short notice and require a total elapsed time of about two weeks. Product: A letter report summarizing field observations, with emphasis on structural conditions; presenting results of the uplift calculations; and making recommendations, if appropriate, for subsequent engineering investigations, including possible use of ground penetrating radar to define the location and extent of voids beneath the pool. Cost: $1,500.00 PHASE II: GROUND PENETRATING RADAR Tasks: 1. Use ground penetrating radar (GPR) to search for voids beneath the leaking construction joint and at other points of interest in or near the pool. 2. Interpret GPR charts. Timing: Phase II could be carried out within two weeks after completion of Phase I. Product: A letter report describing the GPR survey and presenting additional informa- tion on the characteristics of the construction joint and the conditions beneath the joint. Cost: $1,500.00 to $2,200.00 Note: The GPR equipment charge of $600 could be budgeted and billed as a separate item. Mr. Melford A. Dahl May 8, 1984 Page 2 • Donohue PHASE III: OBSERVATION WELLS Tasks: 1. Based on the earlier reconnaissance, select locations for three pairs or nests of observation wells. Each nest would contain a total of approximately 40 lineal feet of well. (The installation, testing, and subsequent observation of these wells is intended to provide information on the nature of subsurface materials, location of the water table, the hydraulic conductivity of soils, pressure on the bottom of the pool and fluctuations in the water table.) 2. Install the three pairs of observation wells, obtain soil samples at close (1 foot or less) intervals, and perform a survey with City assistance to determine the vertical and horizontal locations of the wells. 3. Perform a slug test immediately after well installation for eventual determination of hydraulic conductivity of the soil. 4. Train City personnel in well observation and maintenance techniques. Training: Phase III could be conducted over an approximately two week period, perhaps during the spring or early summer of 1984. Product: A letter report summarizing well installation and startup procedures and observation and maintenance techniques. Cost: $6,500.00 to $7,700.00 Note: 1. In the event that the observation wells do not provide adequate subsurface groundwater and soils data, pumping tests may be necessary. The need for and cost of these tests cannot be determined at this time. 2. The well drilling and installation cost of approximately $1,600 for each of the three well nests could be budgeted and billed as a separate item. Labor for the slug tests, about $800, could also be budgeted and billed separately. Mr. Melford A. Dahl May 8, 1984 Page 3 , Donohue PHASE IV: DATA ANALYSIS Tasks: 1. Analyze the slug test data to determine hydraulic conductivity of the soil. 2. Analyze the soil samples to determine the nature of the soils. 3. Analyze the observation well data to determine the location of and fluctuations in the water table and to determine the hydrostatic pressure on the bottom of the pool. 4. Perform additional uplift calculations to determine if partial or full dewatering of the pool places excessive stress on the pool. Timing: Phase IV would be carried out during and shortly after Phase III and would be completed within four weeks after the completion of Phase III, that is, after all the data are collected. Product: A letter report describing analysis procedures, presenting results, and, as appropriate, making recommendations concerning changes in pool maintenance procedures and possible additional investigation. Cost: $2,000.00 to $2,800.00 Note: For budgeting and billing purposes, the analysis performed by the hydrogeologist (about $1,400) could be separated from the analysis performed by the structural engineer. PHASE V: ALTERNATIVES In the event that earlier phases identify potential solutions to the joint seepage problem or identify other potential problems, such as damaging uplift and solutions, and in the event that the solutions to those problems are not straightforward, such as changing the operation of the pool, preliminary engineering will be performed for alternative solutions. Tasks: 1. Evaluate alternatives such as installation of wells that could be used to - temporarily or permanently drawdown groundwater around the pool. Mr. Melford A. Dahl May 8, 1984 Page 4 Donohue 2. Estimate the cost of technically feasible alternatives. Timing: Phase V would be carried out after Phase IV and would require one month to complete. Product: A letter report presenting a description of technically feasible alternatives and their costs and a recommended course of action. Cost: Cannot be determined at this time. We trust that the ideas presented in this letter will be helpful to you in formulating an approach to the pool problem. We are not recommending that all phases be implemented nor are we suggesting that all phases will eventually be required. We are presenting the phases to suggest some of the efforts that may be required. We suggest doing Phase I and then deciding on the next course of action. Please contact us if you have questions or concerns. We would be pleased to provide any or all of the indicated services. Very truly yours, DONOHUE & ASSOCIATES, INC. ZS if•V t& t•A David P.
