QUESTIONS AND ANSWERS – 01 JUL 2015

Question 11

RFP Section N/A Paragraph N/A

SOW/Technical Specification/Drawings paragraph/page:

Other (Specify):

Question:

There are several sites in this project that require contractor provided escorts. How many workers can one escort oversee and is the escort allowed to be a working member of the crew?

Answer 11:

(1) The number of people each escort can oversee is based on the scope of the work to be done at each project site. The escort must maintain positive control (line of sight) with each employee at all times. If the work crew is spread out over a distance such that a single escort can't maintain positive control over of all employees, then additional escorts would be needed. If all employees are working together and one escort can maintain positive control over all employees, then one is enough. Positive control at all times includes work, break, lunch, bathroom breaks, etc. A smaller work area with fewer workers would require fewer escorts at one time.

(2) There is no prohibition against a crew member serving as an escort, as long as that crew member is able to do their job and maintain positive control of all employees they’re escorting.

If the crew person/escort turns their attention to their job and an employee moves out of sight, it will cause a security response.

DBEH 11-1535K – REPAIR WATER LINES, LC41 FIRE SERVICE, CCAFS (LET)

No Asbestos Containing Material identified in Construction Flag Notes

Other (Specify): N/A

Question:

1. How is the asbestos containing pipe and/or connections to be quantified on the above referenced drawings > construction flag notes?

2. Drawing DBEH 11-1535J, sheet CD-103, Concrete Testing, indicates concrete shall be sampled for asbestos prior to saw cutting or demolishing. How is the number of samples and locations to be quantified? Will this requirement also include testing thrust blocks?

Answer 12:

(1) The contractor is responsible for determining the amount of asbestos pipe that can be abandoned in place and the amount that must be removed in order to safely make the connections between the new and existing pipe.

(2) The contractor shall, at his discretion, determine the location and number of samples that would be representative of common material. This note refers to an EPA requirement for recovered materials; it would only apply to thrust blocks if the blocks were to be recycled (which is not typical).

Question 13

RFP Section Paragraph

SOW/Technical Specification/Drawings paragraph/page: Dwg H, CD-111

Other (Specify):

Question:

Drawing "H", Page CD-111 refers us to Sheet CD-104. CD-104 is not in the package. Please advise.

SOW/Technical Specification/Drawings paragraph/page: Dwg H, CD-114

Other (Specify):

Question:

Note 68 says to sawcut, remove, & replace concrete curb and pavement at Building 411019.

Note 74 says directional bore. Are we boring under the sidewalks or removing and replacing them?

Answer 14:

For FAC 41109, flag note #68 applies and flag note #74 does not. The #74 is a typo; it should refer to flag note #73 on sod restoration. On page CD-114, View 12, flag note #75 is also a typo;

it should refer to flag note #74 for horizontal directional drill.
