S010 6/23/2017 Consigli 0 We are respectfully requesting a 1 week extension to the current bid date (July 11, 2017). We are discovering many subcontractors are declining bid requests, due to the July 4th holiday week. We feel that the project will benefit from stronger subcontractor coverage if the bid date is extended. However, its important to provide notice to the subcontracting community, in well in advance of the current bid date, so subcontractors can work this project into their bid schedules

Bid has been extended in FedBizOpps.

1 Retractable bollards: Specifications, 11 12 34, reference for electric operable retractable bollards and manufacturer’s basis of design is electric operable. Details on LS551 reference manual operable retractable bollards. Are bollards to be manually operable or electric operable? If electric operable, please provide Electric

Power Unit (EPU) location(s) and push button control station location(s).

New bollards are manually retractable. The design for the manual retractable bollard is based off of the design for electrical retractable without the electrical hook-up, so no EPU or controls are required.

2 Retractable bollards: End-User to provide sequence of operation (SOO). Also, End-

User to specify what new or existing equipment retractable bollards are to integrate/interface with – makes, model #’s, control programs etc.

Retractable bollards are manual in nature and do not require a sequence of operation for their operation, nor integration with existing retractable bollards on site.

3 Retractable bollards: Specifications, 11 12 34, reference ASTM M40/DoS K8 rating;

what is the desired penetration rating? Reference additional supporting documentation attached herein.

The desired penetration rating is P1.

4 Retractable bollards: Reference specification section 11 12 34 1.8.A; what is the duration of manufacturer maintenance required? Monthly, Quarterly or Semi-

Annually? Manufacturer’s maintenance guidelines typically call for shift change inspections, daily inspections, weekly inspections and monthly inspections. What will be handled by end-user maintenance team vs. Manufacturer’s certified technician?

There will be limited times the bollards are retracted manually; this will be done primarily for maintenance. Assume the bollards will be retracted monthly.

5 Retractable bollards: The specified manufacturer’s product is not listed on the most recent Department of Defense (DoD) Anti-Ram Vehicle Barrier List. Please confirm that this is not a requirement despite the request for a certified M40/K8 system.

The specified manufacturer's product is not listed as it has not been through a physical crash test. The units should be engineered for the intended rating as with the specified product.

6 Retractable bollards: Metal Fabrications specifications, 05 50 00, do not reference a crash rating for fixed bollards. Are fixed bollards to be crash rated?

Fixed bollards are to have comparable crash ratings to the retractable bollards.
