Approval of a City Council resolution authorizing the City Manager to enter into a
contract with Jimmy D. Dunham, P.E., for engineering services for rehabilitation of the
500,000 g. elevated storage tank located at 3519 Liberty Dr.( directly behind City Hall)
History:
The 1999-2000 City Budget includes a line item for the rehabilitation of the elevated water
storage tank located directly behind City Hall. On August 26, 1999, the annual inspection was
performed by Jilmny Dunham, P.E., a certified elevated and ground tank consultant. This
inspection showed the tank to be in good condition with no water quality deficiencies. However
the protective coatings are the original coatings applied 16 years ago and have exceeded their life
span. The coatings should be replaced to prevent corrosion damage to the steel. Two options
were provided to properly rehabilitate the tank:
* Option One - encapsulate the lead paint on the exterior, provide new exterior and interior
coating and perform miscellaneous repairs - $165,000.00
* Option Two - remove the lead paint from the exterior and provide new exterior and interior
coating, with miscellaneous repairs - $300,000.00.
It is important to note that the lead paint does not have to be removed at this time BUT eventually
it will need to be, once it starts chipping and flaking. The major differences in costs are attributed
to the procedures as prescribed by the TNRCC and the EPA to protect the environment when it is
removed.
Summary:
After meeting with Mr. Dunham and discussing the two options with regards to the long term, it
is the recommendation of staffto select Option Two in the amount of $300,000.00. At this time
the lead primer is in good shape but it could start to chip or flake at any time. At present there is
3519 LIBERTY DRIVE · PEARLAND, TEXAS 77581-5416-19 · (281) 485-2411 · www. ci.pearland.tx.us
approximately 15% flaking and chipping in progress at some of the stress points and this will only
increase. Also if we chose Option One it will be necessary to repaint in 5 - 8 years since we did
not remove the lead primer. A repaint will cost approximately $60,000 to $80,000. And the
bottom line is there is still the lead paint to deal with at a later date. Envkonmental issues and
regulations will not only get tougher hut the cost of disposal of this hazardous material could
escalate.
Total Option One ~ $100,000 (coating) + $13,500 (repairs) = $113,500 (direct costs) x 1.25
(indirect cost) = $142,000 + $21,300 Engineering (design and inspection) =- $163,000
Total Option Two = $195,000 (coating) + $13,500 (repairs) = $208,500 (direct cost) x 1.25
(indirect cost) = $260,000 + $38,800 Engineering (design and inspection) = 298,800
Recommendation:
Approval of a City Council resolution authorizing the City Manager to enter into a contract with
Jimmy D. Dunham, P.E. for engineering services for the rehabilitation of the 500,000g. elevated
storage tank located at 3519 Liberty Dr. in the estimated amount of $38,800. Current monies are
available in account 030-4042-554.15-00 with overdraft issues directed to account 030-4442-
555.11-00.
