Request for Information Question #001:

RFP Section 00010 Solicitation Contract Form - BASE BID Item No. 0001 and Upgrade Main Gate Barriers SOW (May 2020) Page 4, Base Bid Scope of Work Section 1,a., states “Two

(2) in-pavement barrier systems (including 4 individual pop-up barriers)” .

1. Confirm that Base Bid includes only two (2) new, electrically powered, vertical drop arm crash beam systems to be furnished and installed as the two (2) new “in-pavement” barrier systems.

This is correct. The 4 in-pavement pop-up barriers are existing and will be removed as part of the base bid.

Request for Information Question #002:

RFP Section 00010 Solicitation Contract Form - BASE BID Item No. 0001 and Upgrade Main Gate Barriers SOW (May 2020) Page 4, Base Bid Scope of Work Section 1,a., states “Two

(2) in-pavement barrier systems (including 4 individual pop-up barriers)”.

1. Confirm the wording “including 4 individual pop-up barriers” refers to the demolition of existing four (4) units steel-plate wedge barrier systems and that there are not any additional “four units” of a specific type AVB system to be furnished and installed under the Base Bid requirements.

Question #0002 Response:

This is correct. Demolition includes existing four (4) steel-plate wedge barriers.

Request for Information Question #004:

RFP Section 00010 Solicitation Contract Form - BASE BID Item No. 0001.

Upgrade Main Gate Barriers SOW (May 2020) Page 5, Base Bid Scope of Work Section 3.0, states, ‘Furnish and install two complete and operational electrically powered vertical beam barriers that will provide anti-ram vehicle barricades tested and certified to meet ASTM

F2656 impact designation M50, P1 with the capability to stop and destroy a 15,000 lbs.

vehicle traveling at speeds up to 30 mph….( which is less than a M50 designation crash rating)” RFP Drawing C2 states requirement for ASTM M50 Crash Rating but does not state a required penetration rating. The RFP specified crash vehicle weight/speed contradict themselves.

Upgrade Main Gate Barriers SOW (May 2020) Section 347513, Powered Vehicle Barrier Beam, sub-paragraph 1.2.A and 2.1.A.2 state electric powered vertical beam barriers shall be tested and certified to meet ASTM M50/P1

1. What is the required crash rating (vehicle weight and speed)?

2. What is the required penetration rating?

3. Are either Department of State or ASTM crash tested and certified barrier solutions acceptable to be proposed, furnished, and installed?

4. Are the proposed barrier solutions to be proposed, furnished, and installed required to be listed on the most current dated USACE Department of Defense Protective Design Center (PDC) Certified Barrier List?

5. RFP Drawing C2 depicts an 18 ft. clear opening crash beam requirement per lane.

Are the proposed barrier solutions to be proposed, furnished, and installed required to be same as crash tested and certified for the specified clear opening size length?

Example if manufacturer make/model is only listed per DOD Certified Barrier List as a 12 ft. clear opening solution, a proposed 15 ft. or 18 ft. clear opening would not be deemed an acceptable system as not actual crash tested and certified nor listed as a DOD Certified Barrier system for respective clear opening length.

Internationally recognized Testing Methods such as DOS and ASTM provide a structured testing method and procedure to establish a penetration rating for perimeter barriers subjected to a vehicle impact. Knowing the penetration rating provides the ability to select an appropriate barrier for site-specific conditions around a facility. The barrier penetration rating does not imply that a barrier will perform as rated in / under all site conditions, approach routes, points of impact, and topography.

Crash Certification Impact (Weight & Speed) Rating Schedules for Selection.

United Stated Department of State “K” indicates the DOS certified barrier's weight class (15,000 lbs.) vehicle impact speed rating:

K12 = 50 mph (47.0-above mph) K8 = 40 mph (38.0-46.9 mph) K4 = 30 mph (28.0-37.9 mph)

ASTM “M” indicates ASTM certified barrier’s weight class (15,000 lbs.) and vehicle impact speed rating:

M50= 50 mph (47.0-above mph) M40 = 40 mph (38.0-46.9 mph) M30 = 30 mph (28.0-37.9 mph)

Crash Certification Penetration Rating Schedules for Selection.

United Stated Department of State “L” indicates the distance of penetration of the cargo bed beyond the pre-impact edge of the inside of the barrier:

L3 = 3 ft. (915 mm) or less

L2 = 3 ft. to 20 ft. (915 mm to 6.1 m) L1 = 20 ft. to 50 ft. (6.1 m to 15.3 m)

ASTM “P” indicates the test vehicle's distance of penetration upon impact with barrier:

P1 = < 1 m (3.3 ft.)

P2 = 1.01 to 7 m (3.31 to 23.0 ft.)

P3 = 7.01 to 30 m (23.1 to 98.4 ft.)

P4 = 30 m (98 ft.) or greater

Question #0004 Response:

1.-3. Either the K12 or the M50 are acceptable. We understand the ratings. The P1 3.3 ft penetration is acceptable even though it is slightly less stringent than the L3.

4. Yes.

5. The manufacturer should provide the product based on meeting the crash rating requirement for the width required. In accordance with UFGS-34 71 13.19 (February 2020) DOD requires all crash-rated active vehicle barriers (anti-ram) be on the DOD list (which we understand barrier manufacturers are aware of and have access to).

Request for Information Question #008:

Upgrade Main Gate Barriers SOW (May 2020) Section 347113, Non-Powered Vehicle Barrier Beam, sub-paragraph 1.2.C states Bid Option #3-#5 does not require “stopping” post assembly when in the unsecure or open position.

1. Confirm this is not required. It is recommended to have furnished and installed the stopping post so when in the unsecure position, winds or other interferences prevent beam boom arm from closing to secure or swaying into traffic lanes.

Question #0008 Response:

The stop post is not required.

Request for Information Question #009:

Upgrade Main Gate Barriers SOW (May 2020) Section 347513, Powered Vehicle Barrier Beam, sub-paragraph 2.1.B.2, open/close cycles at 7-10 seconds per cycle open or close.

1. What data from what basis of design make/model of a 27 ft clear opening, M50/K12 crash tested, powered, vertical drop arm barrier system was this normal open/close cycle speed derived?

Question #0009 Response:

We do not specify manufacturers.

Request for Information Question #010:

Upgrade Main Gate Barriers SOW (May 2020) Section 347513, Powered Vehicle Barrier Beam, sub-paragraph 2.1.B.3, emergency close to secure cycle of less than 7 seconds.

1. What data from what basis of design make/model of a 27 ft clear opening, M50/K12 crash tested, powered, vertical drop arm barrier system was this emergency cycle speed derived?

2. What is deemed an acceptable emergency cycle less than seven (7) seconds?

3. If the normal close to secure and emergency cycle speed remain unchanged, the same, is this acceptable?

Question #0010 Response:

1. We do not specify manufacturer.

2. Less than 7 seconds means less than 7 seconds. Presumably not 6.9 but technically that would be acceptable. We will evaluate it. The intent is that emergency is faster than normal.

3. Yes, it may be acceptable that the normal operation and emergency operation are the same speed, however; that would mean both are 7 seconds or less. It’s more likely that the normal operation will not be as fast.

1. Appears there are several varying RFP specifications requiring a direct Employee of the proposed Vertical (powered) and/or Horizontal Crash Beam manufacturer vendor to be provided. Confirm all of the above specified scopes require an actual Manufacturer vendor of proposed AVB systems to be a direct Employee(s) and to participate in each of the above scopes of work.

Question #0011 Response:

These are very special systems. Yes, a representative of the manufacturer must install or oversee or guide the installation and certify that their product is installed according to their instructions and that it\they operate safely and correctly. There must also be training for proper and safe operations and maintenance. The GC or subcontractor may install them with the proper direction and inspection.
