Pump Station City of Denton, Texas Dear Mr Arora: We are pleased to present the scope of work and fee proposal for the preliminary design phase of the re -design of the Hardee Field Road Pump Station Attached are the following for your review a) Our Proposed Scope of Work b) As shown on the attached spreadsheets, our proposed lump sum fee is $41,300 As we discussed, we will develop a proposal for the final design and construction phase services after the scope and schedule are determined c) As shown on the attached memorandum, our opinion of probable construction cost is $7,136,000, including a 10%contingency Based on our discussions with the City of Denton and our review of the original plans and specifications, we note the following observations a) The original design of the pump station had an ultimate capacity of 35 mgd The revised design will have an ultimate capacity of 60 mgd, with the capability of serving two pressure planes Tlus may require the use of multiple medium voltage vanable frequency dnves The larger pump capacities will also require larger pump cans, piping, pump control valves, switch gear and starters, more space for pumps and motors, heavier structural loads, larger chemical facilities, and larger HVAC systems We estimate the building will be approximately 25% larger in size Therefore, the pump station will require an almost complete re -design Freese and

August 19,1999 Page 2 b) The 3 mg storage tank will have curtain bathes, or provisions for adding curtain bathes The site will be adaptable to 2 additional 3 mg tanks This will require revisions to the tank inlet and outlet piping, and possibly overflow and chemical feed Piping c) The site plans and details will be revised for the following • Changed off -site drainage conditions • Revised suction piping • Provisions for future multiple discharge pipelines • Revised chemical piping • Revised tank inlets and outlets • Revised on -site roads and parking • Revised site electrical • Changes to site drainage, landscaping, waste systems, and fencing due to other site changes d) The 42-inch pipeline will be revised to a larger size We assume that any additional topographic survey will be provided by the City of Denton, as was done in the original design Some minor reroutes of the pipeline are expected for changed conditions e) The chemical facilities will require larger equipment, larger piping and more space for equipment f) The ventun flowmeter and vault will probably be revised to more current technology, such as ultra -sonic g) The instrumentation and SCADA systems will require an almost complete re -design A station plc will be used Some additional instrumentation may be required This will require adding several sheets to the drawings We assume Denton will want to add electrical bulkheads for motor and control leads, so that the vfd's can easily be switched to alternate pumps h) The standard details and specifications should be updated to current standards Mr P S Arorn.

The revised design will be based on the ultimate future capacity of 60 mgd. Initial pumps will be selected to serve the upper (826) pressure plane Future pumps will be selected to serve the upper and lower (745) pressure planes b) Revise the piping, valves, and power systems for the higher capacity pump selections Make the piping compatible with the future split in flow between the upper and lower pressure planes c) Revise the building layout for larger primps, piping, motors, and power systems (this will affect civil, structural, electrical, mechanical, architectural, and w/ww) d) Review the original design for using the 3 mg storage tanks at HFPS to take excess capacity from the distribution system at night, and pump back into the distribution system during the day Review the piping and valve arrangement i for this scenario e) Provide space for 2 additional 3 mg ground tanks for the future The revised design will include one 3 mg storage tank, as originally designed f) Review the site layout for a bigger btulding, revised chemical facilities (bulk storage and possible relocated chemical facilities), revised drainage for the wider existing City Street, cut and fill issues, 2 additional future tanks, revised site roads, and the revised piping layouts g) Provide baffles in the storage tanks to permit plug flow As a minimum, the tanks will be capable of retrofitting curtain baffles This may require revising the tank inlet and outlet piping and chemical feeds h) Investigate ways ofreductagcosts ofthearchitectural enhancements, without sacrificing substantial aesthetic value. i) Revise the roof skylights for the larger motors, or provide other means of pulling the pumps J) Review the plans and specs for current code requirements k) Review the communication methods including fiber optic and radio between HFPS and Spencer Denton wants open arclutecture SCADA systems and plc's, where feasible 1) Investigate providing facilities for a second power feed at the pump station The electrical substation will be designed and constructed by others as originally planned FNI will coordinate site requirements with the utility company 3) FNI will provide cost estimates for various alternatives as appropriate 4) FNI will provide five copies of a preliminary design report with summaries, recommendations, and cost estimates 5) FNI will attend two meetings with the City of Denton staff to coordinate the preliminary design phase FNI will also attend one meeting with the Public Utility Board to present the findings of the preliminary design phase [dm99351]t Memu,rps,CW wpd ��H�aamvvommme�&gym C O a E 7 a m K IIINRNIIdI� IIIIIIIIIIIIIIH immmmnu �AR� Irl� IBIAnY�I� �I�IIIIIII�III IY� � WIN E n n � n nViO0�11 81 �a8� ° R � va j R i NN P ?
