Site work for a water / sewer project in Athens, Texas. Completed plans call for site work for a water / sewer project.

Contractor shall provide all materials, equipment, and labor to construct a precast concrete manhole configured as shown on the attached sketch. Contractor shall install a seven (+-7) foot deep, 60-inch diameter manhole, including extension of an existing 8-inch, SDR 26 PVC sewer pipe to the newly constructed manhole and extend one full section of 10-inch, SDR 26 PVC sewer pipe on the discharge side of the manhole. Contractor shall apply a corrosion inhibiting coating to all interior surfaces of the new manhole. Contractor is advised that the existing 6-inch forcemain shown on the attached sketch has been relocated and will not interfere with the installation of the manhole described in this notice. Contractor shall indicate total time to complete the work for consideration in awarding this work. 1. Contractor shall place the proposed 60-inch diameter, precast concrete manhole at the location indicated on the attached sketch, shown as N 6770426.72 by E 2802161.84 with a RIM EL +- 507.50. 2. Manhole base shall be placed on screened, one-inch utility rock placed over undisturbed soil with a minimum thickness of 12 inches. 3. Contractor shall locate the end of the existing 8-inch PVC gravity sewer main and extend and connect to the proposed manhole. Contractor shall maintain the 3.65% slope of the existing 8-inch PVC gravity sewer to the proposed manhole. Flow line elevation of the existing 6-inch into the manhole shall be +- 500.0 (contractor to verify). 4. The 10-inch discharge pipe shall be placed on 4.0% slope and ended with a water tight plug or cap. Flow line elevation out of the manhole shall be 499.00. Stub out shall be aligned from the proposed manhole to a future manhole to be located at N 6770506.24 by E 2802100.69 1. Manhole base shall be fabricated to include a channel to accept flow from an internal drop connection of the existing forcemain shown on the sketch at a future time. 2. All piping used shall be SDR 26, PVC. 3. Manhole cover and frame shall be minimum 30-inch clear opening, composite construction, as manufactured by Composite Access Products model code A-1BK30X4-C01CPGSS-H1. 4. Contractor shall coordinate the application of a minimum dry film thickness of 250 mil, corrosion protective coating on all interior surfaces of the manhole following construction. Coating shall extend over any concrete risers needed to set the cover and frame at finish grade to protect surfaces from corrosive gases. Acceptable coatings are: a. RAVEN 405 b. SprayRoq, Spraywall c. Warren S-301 Epoxy 5. Manhole corrosion coating shall be applied by a certified applicator for that coating system and shall have a minimum 10 year, 100% guarantee from date of completion. 6. Contractor shall provide a 2-year, 100% Maintenance Bond for the completed work. *The list of planholders and/or interested bidders is not being tracked by the stakeholders involved with this project.
