IFB 161015 Traffic Control and Incident Response Service Question and Answers

1. From looking at the pictures, it is showing the access point is a manhole. Is that correct? If so, a compact excavator will not fit.

See Addendum 1: The access point is not a manhole. Refer to paragraph IV.B of the Scope of Work, which states, “A portion of the pipe at the lower end will be removed by VDOT prior to contractor beginning pipe cleaning work to allow safe access for excavation and to provide room for loading material into trucks, without encroaching on Big Prater Creek.”

2. This QQ provides minimal information is there a technical POC we can talk to about the scope of work?

Refer to the following paragraphs of the Scope of Work:

Section II of the Scope of Work regarding questions for this IFB, which states, “Any questions regarding this invitation for bid shall be addressed to Chelsa Taylor at

Chelsa.taylor@vdot.virginia.gov.”

IV.D which states, “All work shall be performed following the direction given by the VDOT Contract

Administrator, or designee.”

IV.F.3 which states, “The Contract Administrator, or designee, will review the work site with the

Contractor prior to the start of work. The Contractor shall work any costs for review of the worksite into the bid rate.”

3. The QQ mentions 250’ of pipe, is there an access point at both ends of the pipe?

Refer to paragraph IV.B of the Scope of Work which states, “A portion of the pipe at the lower end will be removed by VDOT prior to contractor beginning pipe cleaning work to allow safe access for excavation and to provide room for loading material into trucks, without encroaching on Big Prater

Creek. The access point is at one end which will be excavated by state forces prior to cleaning the culvert.”

4. We typically clean 48” x 36” elliptical pipe with a hydro vac truck and special nozzles.

See Addendum 1: VAC truck has already been tried for this application and was unsuccessful. Refer to the following paragraphs of the Scope of Work:

mailto:Chelsa.taylor@vdot.virginia.gov

IV.A which states, “VDOT has a 36" x 48" x 250' elliptical reinforced concrete cross pipe that is completely plugged with rock and sediment.”

IV.B which states, “The equipment shall be a radio remote-controlled confined space track loader maximum measurement 34” high x 34” wide , with the capability to fit into this 36” x 48” elliptical drainpipe and adequately remove built up, densely packed sediment, rock and debris from the confined space.”

5. Has VDOT cleaned these pipes with a compact wireless excavator before? If so, who was previous contractor and what brand was used?

See Addendum 1: VDOT has utilized the Microtraxx 3234 or Microtraxx 3434 for similar applications. See Addendum 1. Refer to paragraph IV.B of the Scope of Work which states, “The equipment shall be a radio remote-controlled confined space track loader maximum measurement 34” high x 34” wide, with the capability to fit into this 36” x 48” elliptical drainpipe.”

6. We are requesting more pictures of the section of pipe that needs cleaning from both ends of pipe.

Refer to Attachment C for photos of the work site.
