<br /> Recommendations and Quoted Price Comments and Recommendations
<br /> 3, Pressure wash interior dry surfaces, A complete power wash is not necessary,
<br /> I spot repair a small area of peeled Cleaning isolated mildew spots is
<br /> paint; $9,500 recommended, and the small area of peeled
<br /> paint should be repaired, Estimated cost:
<br /> I $1,200,
<br /> 4, Install confined space entry signs near Not common practice, Not required since the
<br /> roof openings; "free with order" City closely controls access to the roof area
<br /> I and can ensure that only qualified personnel
<br /> are allowed to enter the tank,
<br /> I 5, Install lightning protection on the water Not common practice in this area. Not
<br /> tower; $1,250 recommended by Kaeding & Associates, our
<br /> electrical subconsultant.
<br /> I 6, Spot sandblast, spot prime, brush Based on the photos in the 1996 report and
<br /> blast all surfaces, stripe coat seams, on an inspection from the roof hatch, with the
<br /> and topcoat entire tank interior; tank full, it appears that the tank lining is in
<br /> I $95,100 good condition and that only minor spot
<br /> repairs are required, Repainting the entire
<br /> tank interior is not recommended at this time,
<br /> Ie Estimated cost: $15,000 to $30,000
<br /> 7, Pressure wash the tank exterior; Not necessary at this time,
<br /> I $13,500
<br /> 8, Install a new tank vent to relieve Ice build-up on the screen has not been a
<br /> vacuum or pressure in case of ice problem, Vent modifications such as
<br /> I build-up on the vent screen; $4,810 replacing the metal screen with a fiberglass
<br /> reinforced nylon screen would lower the
<br /> potential for ice build,up on the screen,
<br /> I Estimated cost: $500
<br /> I In summary, the recommendations and quotes made by Pittsburg Tank and Tower appear to be
<br /> excessive, high priced, and based, in part, on possible misinterpretation of OSHA and AWWA
<br /> codes and standards, The Pittsburg Tank and Tower recommendations and price quotes total
<br /> $147,211,
<br /> I Based on our evaluation, minor modifications and repair work are recommended, with an estimated
<br /> cost of $18,200 to $33,200, Since a detailed examination of the tank lining is not possible without
<br /> I draining and rigging the tank, the first step in a maintenance and repair contract should be to rig
<br /> the tank interior and thoroughly examine the tank lining, Since the need for additional work may
<br /> be identified after a detailed examination of the tank interior, the City should consider budgeting
<br /> I for a total construction cost of $50,000,
<br /> .. It is recommended that the maintenance and repair work be completed in 1997 or 1998, If the City
<br /> would like to proceed with the project, the City should authorize the preparation of specifications
