PAINTING EXISTING STOCKADE WWTP
PICKENS COUNTY, SOUTH CAROLINA
GENERAL PART 1 -
SCOPE AND SCHEDULE 1.1
The Pickens County Stockade Wastewater Treatment Plant (WWTP) in Pickens, South
Carolina is a package wastewater treatment system consisting of side-by-side treatment
trains that make a 24’ x 54’ x 11’ rectangular tank (see Addendum A and B). The tanks
are partially buried in the ground: the tanks extend approximately 4 feet above the
ground.
A. The work of this section includes the surface preparation and painting of all surfaces
(excluding buried, outside of tank) of the WWTP, including all painted surfaces on
the catwalk excluding galvanized surfaces, and as specified herein.
B. All surfaces are to be blasted and will receive a three-coat system (see Part 2,
Section, 2.2 and 2.3). The interior surfaces will also receive a stripe coat after the
first coat.
C. To the best of the Owner’s knowledge, the current coating system does not contain
lead, but measures may be required to control work-in-process from affecting
surrounding properties. The nearest property improvements or roadways are 450’
from the tanks.
D. The Contractor shall provide all materials, labor, equipment, and tools, required to
perform the work listed in these specifications, including disposal of generated waste.
Cost of work is per CONTRACT BASE BID unless otherwise stated.
E. The bids will be due on March 18th
2015 at 2:00 pm in the boardroom at the
Administration Office. (222 McDaniel Avenue B-4 Pickens SC 29671) Bids shall
arrive in sealed envelopes with “Tank Painting” clearly labeled on the envelope.
F. All bids must be accompanied with a bid bond in the amount of 5% of the contractors
bid.
G. The successful contractor will be required to submit a Pay and Performance bond in
the amount of 100% of the contract price. The successful contractor will also be
required to supply the County with their Certificate of Insurance document.
H. The completion date will be October 15, 2015. The ability to perform the
improvements sooner will be preferred in the selection of the Contractor. (See
Special Conditions D & E).

SPECIAL CONDITIONS 1.2
A. The condition of the steel tanks at the Stockade WWTP is uncertain. If, in the
Owner’s sole opinion, the repairs necessary to successfully coat the tanks would be
inordinately expensive, the Owner reserves the right to cancel the contract. In this
event, payment will be made to the contractor on a percent-complete basis for work
complete at the time of cancellation, plus any payable unit-price items and reasonable
demobilization fees.
B. The Stockade WWTP will remain in operation during painting operations. One tank
at a time will be emptied and painted while the other remains in service. The
Contractor shall protect the portions of the WWTP remaining in service from the
entry of blasting materials, paint overspray, and other foreign materials resulting
from painting activities.
C. The Owner will have the first tank prepared for the Contractor by a date to be
established at the Pre-Bid Conference. Tank preparation will be limited to
withdrawing as much wastewater from the tanks as possible with a 2” sump pump.
After this tank has been completed by the Contractor (including curing time), the
Owner requires three (3) days to prepare the second tank for painting.
D. The Bidder shall submit a milestone schedule with the Bid showing completion by
the designated completion date. The milestone schedule shall include allowances for
the Owner’s preparation time for the second tank in addition to a reasonable number
of delay days for rain, mud, and other adverse weather conditions. The successful
Bidder will be required to adhere to this schedule.
E. Liquidated damages for failure to complete the project by the deadline in Section
1.1.E. shall be $250.00 per day.

maximum allowable thickness, with poor application appearance as
determined by the Owner, will be considered unacceptable and shall be
removed by the Contractor at no additional cost to the Owner.
4. Application of the coating shall provide a tight film of specified uniform
thickness, well bonded to the substrates or underlying coat. This is to
include crevices and corners. The coating shall be free from runs, sags,
dry spray, over spray pinholes, excessive roller nap, skips, excessive film
build-up, mud cracking or other irregularities.
5. Primer coat shall have sufficient thickness to cover anchor profile.
6. Coating thickness measurements will be in accordance with SSPC-PA-2.
However, no spot measurement reading lower than the minimum
thickness will be allowed.
7. Coating thickness in excess of 20% over maximum dry film thickness is
acceptable provided it is isolated and the coating is uniform in
appearance.
8. Low film thickness shall be corrected by the application of an additional
coat or coats of the same material, at no additional cost to the Owner.
C. Stripe Coat: After primer coat has been applied and prior to full intermediate
coat, brush or roll intermediate coat thinned at least 5 percent on bolts, nuts,
edges, welds, seams, steel to steel interface and any irregular surfaces, to cover
visible voids in coatings.
D. Any blasted spot repairs shall have the coating around the repair areas feathered
back to remove loose coating and to give a uniform appearance. The spot repair
Request for Bid 2015-17
