The following are Questions and Answers from Pre-Bid Conference, June 26, 2019
through July 5, 2019:
1. What is the estimated cost range for this project?
Answer: Estimated annual cost for this project is $250,000. Bid Attributes,
Section 1, Contract Term states “contract for one (1) year, effective from
date of award. The City and the Supplier shall have the option to renew this
contract for an additional two (2) one-year periods.
2. In reviewing the equipment specifications list for the above referenced RFP,
the ‘resolution/detection required’ levels for the H2S meter and PID are
listed as 3 parts per billion volume (ppbv) and 1 ppbv, respectively. Is that
correct, as it seems that most meters have detectable limits of 1 to 3 parts per
million volume (ppmv) for H2S and 1 ppmv for PIDs?
Answer: The detection limits listed are accurate. For instance, TCEQ’s H2S
30-minute limit is 0.08 ppm. A detection limit of 1 ppm would not be
sufficient.
3. Measure upwind and downwind at the same time; simultaneously?
Answer: Upwind and downwind must be measured simultaneously in order
to measure the impact from the site while subtracting background
measurements.
4. Is visual equipment required?

on padsite continuous”.
6. On line item No. 9, “72 hour noise study”; is this real time?
