RFP#6540- ADDENDUM #1
1. The previously sealed joints on the concrete streets look to be in fairly good
shape, missing partial tar, or having some low/sunken tar. From a value standpoint,
rather than cut out the remaining tar, which appears to be well adhered yet, can
these be blown and resealed using a narrow (2”) over band? Or will all 50,000 lf
need to be cut out and refilled?
These Streets need to be cut out and repaired properly, per our specification. No short
cuts
2. Will the excessively spalled areas on Bell Street be omitted from crack sealing?
Manufactures installation specifications state that reservoir should not exceed 1 ½
inches in width.
If the reservoir is larger than 1 ½”, do not fix it.
3. Considering the average random concrete cracks account for a small percentage
of the overall LF, would the city consider over banding only vs. routing the random
cracks, again (from a value standpoint)?
No.
4. If the 50,000 LF is not used up on Bell and Colorado St, will the additional
amount be added to asphalt streets or additional concrete streets?
Yes
5. On page 50 of exhibit 2, there is reference to project signs. Due to the nature of
the project being in a multitude of locations, can these signs be omitted from the
project?
No. Signage cannot be omitted. Mobile Arrow boards can be used instead.
6. Will the curb joint between the concrete curb pan and the asphalt street be sealed
on the asphalt streets? It appears it was done on Montecito to some extent and a
couple other streets that had been sealed previously, but not all.
If it needs to be sealed, then yes please seal the curb joints.
7. Is there a requirement for a Bid bond on this RFP/ Project?
No Bid Bond is required. Payment and Performance Bonds are required upon
execution of the contract (at 100% of the contract value).
8. Does City of Denton provide a Street Map for these projects?
No.
9. Can I get a “Plan Holders” list by chance, as this would allow me to quote any
other contractor who may intend to bid?
The City of Denton utilizes the Centralized Master Bidders List (CMBL) provided by
the State of Texas for the vendors listed under NIGP Code #745-80, located at
https://mycpa.state.tx.us for email notification of this Request for Proposal. The
