J . - - CITY OJ!' 1lRDEN BILIS HEH:'RANOOIl morE: March 12, 1993 TO: DorotlIy Person, city l\dminist:rator FRCH: Dan Winkel, Public Works SUperint.......st IJ. vJ SUBJECT: Structure R"t"";1"S and PaintiDq Interior and Eld:erior of water Tower on Fernwood Avenue The city public works ereN discovered a rust problem inside of this tower while doing routine maintenance early last year. In October of 1992 the city authorized A.E.C Engineering to do a complete survey ani inspection of this tower . 'Ihe tower was =iginally erected in 1968 ani has had only min= interior painting done since that time. The exterior was last painted in 1981. 'Ihe A.E.C. report indicates that it is definitely time to make major changes ani updates to this tower. I have diSC"lSsoo this with other eI'Y,}ineers ani public works superintendents who indicated that these kinds of repairs may be . expected after a 25-year service life. In the future we will do a certiIied inspection of both towers every three to five years. 'Ihe A.E.C. report describes interior ani exteri= concerns including that of lead based paint. The interior wet coating above the high water nark ani exterior dry coating need to be painted within the next one to two years. Both of these areas currently have a lead based paint that should be removed as soon as is possible. The interi= wet coating below the high water nark ani also the interior dry coating need spot repair ani limited area replacement within one to two years. The interior area below the high water nark is not a lead based paint. Also, the interi= dry coating does not appear to be a lead based paint. The entire exterior surface is a lead based paint, ani should be replaced a=ding to Federal ani state regulations. The report also indicates that there are structural repairs that also need to be completed. We have some severe failure of some coated areas within the interior bowl of the tower. Soo\e of the structure support steel may also have to be replaced. During the inspection, a =nstruction deficiency was found, where the roof rafters are not connected to the tank shell. 'Ihis definitely needs to be =ected with the installation of gusset plates to connect the two. 'Ihe inspection report also lists some interior options that should be completed ani may help to extend the life of the tower SUPJXlrt structure ani also the coated, or painted areas. 'Ihe exterior of the tower has a lead based paint ani needs to be removed using a screen that would prevent paint from contaminating the surrounding areas. - It was also recommended to add two hinged roof manways to comply with a.S.H.A. confined space entry requirements. The aircraft warning light ani bracket also need to be updated. A neN tank vent is also recomrnencled.
