RFP FOR TRUCK-BASED LARVICIDING ACTIVITIES
QUESTIONS AND RESPONSES 1.
Page 14, Section E. 6. RFP states an automatic monitoring record is a required part of the certified reports made available to TCPH after application(s). Some of the machinery utilized for these types of applications are capable of automatic monitoring systems while some are not. This application technique is novel for this type of urban application and so the automatic monitoring systems have not been fully integrated into the machinery as of this date. The pumping systems and electronics used for certain brands of machinery make automatic monitoring and dosage control difficult to achieve. Is this Automatic Monitoring Record a requirement or only desired when available? Response: Automatic Monitoring Record is preferred but not mandatory.
2.
Page 14, Section E. 6a. Given known issues pertaining to consistency of surveillance methods, who will be setting pre-application traps and the mentioned post-application traps? Response: The Vendor doing the application is responsible for setting up the cups beforehand.
3.
Should dry petri dishes be utilized to assess droplet and material deposition throughout the treatment area and then larvae introduced into the dishes in a laboratory setting? Are these larvae field collected from this area or reared? Response: Field-collected larvae are preferred.
4.
If reared larvae are to be utilized, who is responsible for supplying larvae and should these larvae be field-collected strains or susceptible laboratory strains? Please provide clarification for efficacy testing. Response: The vendor is responsible for supplying larvae for which field-collected strains are preferred.
5.
Page 16, Section B. 2. This section states the requirements of the GPS technology on the spray system. The chemical application rates are recorded through the automatic variable flow which is not available on all the types of machines that may be utilized for this scope of work. All other features stated in this section are attainable. Will the chemical application rates recorded by the automatic variable flow control system be required for this? Response: No. The recording of chemical application rates by the automatic variable flow control system is not required but preferred.

RFP FOR TRUCK-BASED LARVICIDING ACTIVITIES
QUESTIONS AND RESPONSES 6.
Page 16, Section B, 3. This section states automatic variable flow control is required, if possible. Again, as stated in Question 1, some of the machinery is capable of incorporating this feature while other machines are not. Will the RFP require this feature as stated on Page 14, Section E, 6. or is this feature optional as stated in Page 16, Section B., 3? Response: The recording of chemical application rates by the automatic variable flow control system is not required but preferred.
7.
Page 35 and 36, Pricing Tables. The product labels mentioned in this RFP specify the product usage rates as oz/acre. Will the Rate Recommendation section of the pricing table be changed to reflect oz/acre to standardize with the product labels? Response: Yes. The Rate Recommendation has been changed to “oz/acre” to standardize with the product labels.
8.
Please clarify the intent of “24 hour response time.” Does the Vendor have to reply to Tarrant County within 24 hours to state the planning for activating operations has begun? Does the application of larvicide product have to begin within 24 hours of notification? What is Tarrant County’s expectation as to when truck larviciding should be started? Response: Twenty-four (24) hours is the preferred response time.
9.
Can previous truck LV larviciding efficacy evaluations suffice for this requirement? Can an alternative efficacy protocol be proposed in lieu of Page 14, Section E, 6a? Response: No. Data must be obtained in current treatment location.
10.
We do not recommend or support the use of Vectobac 12AS for truck, ATV or backpack low volume (LV) larvicide spraying. We recommend the use of VectoBac WDG for this RFP. Will Tarrant County make this change to VectoBac WDG for this RFP #2017-118? Response: The desired larvicide product listed has been changed from “VectoBac 12AS or comparable” to “VectoBac WDG or comparable.”
