Correct the data required by safety signs daily.

2.2 TEMPORARY TRAFFIC CONTROL

2.2.1 Haul Roads

Contractor shall utilize existing haul roads constructed at the project site. Contractor is responsible for maintenance of these haul roads including providing dust control measures and repair of roads damaged by Contractor vehicle access.

Amendment 0002*************************************************************

Any and all access to the Mt Eden gate must be coordinated in advance with Ft Knox Resident Office. A weight limit of 15 tons is enforced on this road and there is not an option to bond that roadway in order to increase that weight limit.

The Rodgers Hollow range area will not be accessible via the main entrance

SECTION 01 50 00 Page 4 during flooding/high water events. The road becomes inaccessible when the Ohio River McAlpine Lower gauge reaches approximately 48 ft. It is common for this situation to occur annually, and sometimes more often. The construction site would still be accessible to smaller vehicles via an alternate road but no deliveries, semis, etc. would be allowed. If this situation does occur, this period of time will be treated as an unusually severe weather event and the Contractor may be entitled to a Contract time extension in accordance with the paragraph titled "Time Extensions for Unusually Severe Weather" (ER-415-1-15) and FAR 52.249-10 "Default (Fixed Price Construction)"

************************************************************Amdendment 0002

Fencing must remain rigid and taut with a minimum of 200 pounds of force exerted on it from any direction with less than 4 inches of deflection.

2.3.2 Chain Link Panel Fencing

Temporary panel fencing must be galvanized steel chain link panels 6 feet high. Multiple fencing panels may be linked together at the bases to form long spans as needed. Each panel base must be weighted down using sand bags or other suitable materials in order for the fencing to withstand anticipated winds while remaining upright. Fencing must remain rigid and taut with a minimum of 200 pounds of force exerted on it from any direction with less than 4 inches of deflection.

1.2 DEFINITIONS

a. "Cementitious material" as used herein must include all portland cement, pozzolan, fly ash, and slag cement.

b. "Exposed to public view" means situated so that it can be seen from eye level from a public location after completion of the building. A public location is accessible to persons not responsible for operation

SECTION 03 30 00 Page 11 or maintenance of the building.

c. "Chemical admixtures" are materials in the form of powder or fluids that are added to the concrete to give it certain characteristics not obtainable with plain concrete mixes.

d. "Supplementary cementing materials" (SCM) include coal fly ash, , slag cement, natural or calcined pozzolans, and ultra-fine coal ash when used in such proportions to replace the portland cement that result in improvement to sustainability and durability and reduced cost.

e. "Design strength" (f'c) is the specified compressive strength of concrete at time(s) specified in this section to meet structural design criteria.

f. "Mass Concrete" is any concrete system that approaches a maximum temperature of 158 degrees F within the first 72 hours of placement.

In addition, it includes all concrete elements with a section thickness of 3 feet or more regardless of temperature.

g. "Mixture proportioning" is the process of designing concrete mixture proportions to enable it to meet the strength, service life and constructability requirements of the project while minimizing the initial and life-cycle cost.

h. "Mixture proportions" are the masses or volumes of individual ingredients used to make a unit measure (cubic meter or cubic yard) of concrete.

i. "Pozzolan" is a siliceous or siliceous and aluminous material, which in itself possesses little or no cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties.

j. "Workability (or consistence)" is the ability of a fresh (plastic) concrete mix to fill the form/mould properly with the desired work (vibration) and without reducing the concrete's quality. Workability depends on water content, chemical admixtures, aggregate (shape and size distribution), cementitious content and age (level of hydration).
