“10. Section 03 30 00 CAST-IN-PLACE CONCRETE is revised as follows:

a. Paragraph 1.1 REFERENCES, ASTM International (ASTM), add the following after ASTM C78/C78M (2018) Standard Test Method for Flexural Strength of Concrete (using Simple Beam with Third –Point Loading):

ASTM C685/C685M- (2017) Standard Specification for Concrete Made by Volumetric Batching and Continuous Mixing

b. Paragraph 1.3 SUBMITTALS, add the following as noted:

SD-03 Product Data, add: Batching and Mixing Equipment

SD-06 Test Reports, add: Concrete Mix Proportions; G

c. Paragraph 3.6 BATCHING, MEASURING, MIXING, AND TRANSPORTING CONCRETE is revised to add the following paragraph as the second paragraph:

The option of using an on-site batching and mixing facility conforming to the requirements of either ASTM C94/C94M or ASTM C685/C685M is available. The facility must provide sufficient batching and mixing equipment capacity to prevent cold joints. Submit the method of measuring materials, batching operation, and mixer for review, and manufacturer's data for batching and mixing equipment demonstrating compliance with the applicable specifications.

12. Section 31 23 00.00 20, Paragraph 3.6.2 is revised to add the following after the first sentence:

Base bids on the assumption that the crushed/manufactured on-site soil is suitable to meet fill specifications.”

2. Section 01 30 00, ADMINISTATIVE REQUIREMENTS, is revised as follows:

a. Paragraph1.4.2.1 Workforce Housing Facilities for “Temporary Resident Workers” is revised to add the following paragraph b.:

b. Information on man-camps that may be available for rent on Angaur is attached at the end of this section.

b. Add paragraph 1.14 Registered Professional Engineers and Registered Architects as follows:

1.14 Registered Professional Engineers and Registered Architects

All references to the terms ‘professional engineer’ or ‘registered architect’ throughout this Specification refer to professional engineers and registered architects licensed in the United States, unless otherwise specified.

3. Section 01 57 19 TEMPORARY ENVIRONMENTAL CONTROLS is revised to delete the following from paragraph 1.5.2:

Base bids on the assumption that the Soil Disposal Site SD1 is sufficient to accommodate the excavated basalt and excess soil. Base bids on no fees or costs for the terms of use of SD1. Any fees of costs associated with the terms of use of the SD sites, SD1 or SD2, incurred will be handled as a changed condition. Submit the negotiated terms of use and any costs associated with complying with the terms of use to the Contracting Officer prior to commencing work.

4. Section 03 30 00 CAST-IN-PLACE CONCRETE is deleted in its entirety and replaced with the attached Section 03 30 00 CAST-IN-PLACE CONCRETE, AMENDMENT No. 0005, dated April 19, 2022.

5. Section 31 05 22 GEOTEXTILES USED AS FILTERS, paragraph 2.2.2 Site Verification and Testing is deleted in its entirety and not replaced.

6. Section 31 23 00.00.20 EXCAVATION AND FILL, paragraph 3.6.1 Common Fill Placement at Babeldaob Site is revised to delete paragraph 3.6.1 in its entirety and to replace it with the following:

The on-site excavated materials from Babeldaob site, conforming to satisfactory material, may also be used for fill below the top 0.6 meter of finished grade in non-load bearing areas, provided the contractor can achieve 85 percent of maximum dry density of the compacted soil. Place in lifts of 254 mm in loose thickness. Aerating on-site cohesive clayey and silty excavated material from Babeldaob excessively moistened by rain to satisfactory moisture content may not be practical due to inherent high moisture content. Mixing with drier soils may not be practical as cohesive clayey and silt soils are hard to break up sufficiently for mixing. On-site excavated materials form Babeldaob site must not be placed below antenna pad, antenna foundations, concrete slab foundations, spread footings, MSE Wall, concrete pavements, asphalt pavements, and tank foundations.

The Contractor shall base their bids on importing common fill that meets this specifications for placement at the Tx Babeldaob Site .

Provide aggregates consisting of crushed stone, crushed gravel, crushed slag, screenings, natural sand and mineral filler, as required. Submit sufficient materials to produce 90 kg of blended mixture for mix design verification. The portion of material retained on the 4.75 mm sieve is coarse aggregate. The portion of material passing the 4.75 mm sieve and retained on the 0.075 mm sieve is fine aggregate. The portion passing the 0.075 mm sieve is defined as mineral filler. Submit all aggregate test results and samples to the Contracting Officer at least 14 days prior to start of construction.

When a test panel does not meet one or more of the requirements, the test panel must be rejected, removed, and replaced at the Contractor's expense. If the test panels are acceptable, they may be incorporated into the project with the approval of the Contracting Officer.

b. Paragraph 3.4.4 Fixed Form Paving is deleted in its entirety and replaced with the following:

Forms may be steel or wood. Forms may be built up with metal or wood, added only to the base, to provide an increase in depth of not more than 25 percent.

Forms must be set on firm material cut true to grade so that each form section when placed will be firmly in contact with the underlying layer for its entire base. Forms must not be set on blocks or on built-up spots of underlying material. Forms must remain in place at least 12 hours after the concrete has been placed. Forms must be removed without injuring the concrete.

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 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 70 degrees C within the first 72 hours of placement.

In addition, it includes all concrete elements with a section thickness of 1 meter 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).
