Drawing C-501 showing a detail that appears to be an Ameristar Impasse II cabled System does meet any crash rating. The cables DO NOT have the proper spacing and are located too low on the fence. There are 3 rated systems on Keesler AFB. Below are the ratings and the requirements that must be kept for each specific K- rating.

From the three listed Ameristar Systems listed below, which system or rating would the scope of work need to be based upon?

a.K-4 rated system 15,000 lb. vehicle@ 30 mph. This system can have spans of rated Fence line of 29 feet in length and up to a 40 foot in length and will maintain this rating. This is a 2-cable system.

b.K-8 rated system 15,000 lb. vehicle@ 40 mph this system has to be maintain at a 32-foot span only between the Anchor posts. This is also a 2-cable system. If you have a run that is that is below 29 feet or larger than 36 feet it will require to have a Ameristar bollard system behind the that line of fence.

c.K-12 rated system 15,000 lb. vehicle @50 mph This system must be kept to 32' runs to maintain the crash rating. This system requires 3 cables on the fence and rebar cages on the Anchor Posts Footers. If any run is less than 29 feet or over 36 feet, this will require an Ameristar Bollard system behind that run of fence. Any place that you have a section of 4' or less no cable or bollards are required.

Drawi ng C-

K-4 rated system is the system that the scope of work needs to be based upon. The system shall also be in compliance with ASTM F2656 (M30).

The bollard system behind the fence is not needed.

Drawing sheet C-501 is for reference only, contractor is to follow the manufacturer requirements for the fencing.

Drawing sheet C-103 will be used for schematic purposes only, please disregard the coordinate points for post locations and follow the manufactuer requirements to meet K-4/M30.

All of the above Ameristar systems include Ameristar accessories and hardware that have been tested which are carbon steel with their Armor-Galv. Black coating. They do not use Stainless steel due the strength. Would this be acceptable?

Material may vary by manufacturer, fence must meet K-4/M30 rating and aesthetically match the existing fence.

Will Keesler have personnel onsite to provide utility locates for utilities inaccessible to 811 One Call?

811 is directed to Keesler and all known utilities will be located.

Please identify acceptable areas for contractors’ laydown/staging/storage yard.

The location will be coordinated with the Construction Manager to be located adjacent to jobsite.

Please provide a Geotech report and water table level for this project.

That information is not available.

What are the contractors requirements for maintaining accessibility to building 4605? Is it anticipated that a temporary access will be needed? Per Sheet C-401, General Sheet Notes #1…States that the demolition at White Ave & Judge Sekul is to take place after the perimeter fence is installed, therefore eliminating access currently being used for building 4605.

C-401

Contractor is required to provide a traffic control plan that will show how access to B4605 will be maintained throughout the duration of the project.

Once fenceline is closed, access to B4605 will be through White Ave. gate during demoltion phase.

Please clarify General Note #7 on Sheet C-100…Is the contractor required to provide separate individuals for the roll(s) of Project Superintendent, Quality Control Representative and Safety Representative. Will sharing of responsibilities be allowed?
