A: There are no existing pipes to be abandoned in the project.

Q: #21. On sheet C-3, a 12" steel pipe is shown but it is unknown as to whether this pipe is existing or to be installed by the contractor. Please confirm whether this is an existing pipe that is just to be tied into or if this is a new install. Please also confirm the wall thickness for this pipe as it is only shown as "STD WALL STEEL PIPE".

A: The pipe is to be new at a thickness of 0.375”. Please see revised C-3.

A plan sheet showing a profile and section view of the proposed embankment. The drawing shall clearly indicate the size, type, location and orientation of all Geofoam blocks.

The location and type of connectors Proposed ballasting or guying techniques Proposed placement methods

Prior to the delivery of the EPS Geofoam blocks, CONTRACTOR shall furnish ENGINEER with a copy of manufacturer’s test reports or a third party’s certified test report showing that the Geofoam blocks meet the physical properties and standards listed below in Table 1.

The Contractor shall submit to ENGINEER a Manufacturer’s Certificate of Compliance for the first 100 cubic yards and for every 1,500 cubic yards thereafter before the Geofoam is delivered to the site.

The Certificate of Compliance shall include current inspection reports showing that the Geofoam manufacturer is in compliance with a UL follow-up service program for both flame and physical properties. In addition, computer generated stress-strain data and the accompanying curves shall be produced from compressive testing and supplied to ENGINEER. The curves and/or data shall clearly indicate the stress at 1% strain and the modulus of elasticity.

HANDLING, DELIVERY, AND STORAGE

CONTRACTOR shall prevent damage to the Geofoam blocks during delivery, storage, and construction. Prior to delivery of Geofoam block fill to the project site, CONTRACTOR shall review and be thoroughly knowledgeable with the manufacturer's care and handling recommendations. Any Geofoam block that is exposed to sun light for more than six months shall be covered with an opaque material to prevent ultraviolet light degradation.

CONTRACTOR shall protect the Geofoam blocks from: (1) Organic solvents such as acetone, benzene, and paint thinner; (2) Petroleum based solvents such as gasoline and diesel fuel; (3) Open flames.

Placement of embankment soil cover material will require special procedures and careful selection of appropriate construction equipment to prevent damage to the Geofoam fill.

No heavy construction equipment or vehicles shall be allowed directly on the Geofoam.

Any damage to the Geofoam blocks resulting from CONTRACTOR’s vehicles, equipment or operations, shall be replaced by CONTRACTOR.

Damage to Geofoam shall be corrected as follows:

083.43.210 31 23 23.43 - 3

Slight damage less than 1 cubic foot may be left in place as is.

Moderate damage between 1 cubic foot and 35.3 cubic feet shall be filled with sand.

Geofoam blocks with excessive damage (i.e. exceeding the "moderate" category) shall be replaced with Geofoam blocks which meet the damage material design properties.

Geofoam blocks not meeting the damage criteria may be cut to eliminate the excessive damage and the remaining, undamaged, portion of the block may be used within the fill, provided the undamaged portion of the block meets all other design requirements.

QUALITY ASSURANCE

Quality assurance testing and sampling, to monitor the conformance of the Geofoam fill with the specification requirements, will be completed as directed by ENGINEER. Density, compression and geometry (dimensional tolerances) testing shall be conducted using 2-inch cubes cut from representative blocks. Blocks in conformance with contract requirements can be used to make required fills.

Testing shall be conducted on samples taken from the first 100 cubic yards of each Geofoam type manufactured for project delivery and at a rate of one test per 1,500 cubic yards thereafter. No more than 100 cubic yards of Geofoam shall be manufactured until ENGINEER has approved the material.

ENGINEER has the right to randomly sample the manufacturing plant. If any block does not conform to the physical requirements, it may be rejected by ENGINEER.

MEASUREMENT AND PAYMENT

The completed EPS Geofoam fill-work will be measured by the in-place volume in cubic yard. No credit will be given for wasted material.

PART 3 EXECUTION

SUBGRADE PREPARATION

Clear and grub the site in accordance with Section 31 11 00 – Clearing, Grubbing, and Stripping.

Dewater the site in accordance with Section 31 23 19 – Dewatering.

The grade on which the Geofoam fill will be placed shall be graded to the elevations shown in the contract drawings. The finish-grade shall be smooth and free from holes and protruding objects. An 8 inch leveling pad shall be constructed over the prepared grade.

The leveling pad material shall be sand, pea gravel or any locally available permeable material approved by ENGINEER.

PLACEMENT

EPS Geofoam fill shall be placed to the lines and grades shown in the plans and as directed by ENGINEER. The surface of a layer of Geofoam blocks to receive additional Geofoam blocks shall be constructed with a variation in surface tolerance of no more than

0.05 feet in any 10 ft interval. All blocks shall accurately fit relative to adjacent blocks. No gaps greater than 0.07 ft will be allowed on vertical joints.

083.43.210 31 23 23.43 - 5

The finished surface of the Geofoam immediately beneath pavement sections shall be constructed to within the tolerance of zero to minus 0.20 ft of the indicated grade.

The finished surface of the Geofoam on side slopes that receive soil cover shall be constructed to within a tolerance of plus 0.30 ft to minus 0.30 ft of the indicated grade.

Blocks placed in a row in a particular layer shall be offset 2.0 ft relative to blocks placed in adjacent rows of the same layer as shown on the plans. In order to avoid continuous joints, each subsequent layer of blocks shall be rotated on the horizontal plane 90 degrees from the direction of placement of the previous layer placed.

When needed to prevent blocks sliding during embankment construction, Insulgrip by Insulfoam, Geogripper by Foam Control, or approved equal, plates or a urethane adhesive such as Flexible Fast should be placed between horizontal layers of blocks. For the number required, refer to Paragraph 3.3 of this specification.

Blocks shall be cut using a hot wire.

Because of the light unit-weight of the geofoam fill, it is CONTRACTOR's responsibility to provide temporary weighting and/or guying as necessary until all the blocks are built into a homogeneous mass, and the pavement section as well as any soil cover are in place.

Embankment over the side slopes of the Geofoam fills shall be placed starting at the bottom of the slope in such a manner to prevent damage to the Geofoam. Finished Geofoam on side slopes shall have a minimum of 2 ft embankment cover.

The embankment material, in areas beyond the lateral distances necessary to protect Geofoam from damage, shall be compacted according to Section 31 23 23 – Excavation and Backfill for Structures. The intent of this requirement is to minimize the encompassed zone around the Geofoam fill.

During placement of the load distribution slab over the top surface of the Geofoam fill it is permissible to use rebar supports to support the reinforcing steel during concrete placement.

CONNECTORS

Connectors shall be galvanized steel multi-barbed connectors or a urethane adhesive.

Each connector shall have a lateral holding strength of at least 60 lbs when tested with an EPS15 Geofoam.

Install a minimum of 2 connectors for each 4 ft x 8 ft section of Geofoam material or as shown on contract drawings or directed by ENGINEER. Press firmly into the rigid foam until the connector is flush with the surface. Position the next foam block as specified and seat firmly before placing subsequent blocks.
