I. Respond to Questions

1. Question: Jacobs Runway 17-35 Demolition Construction and Safety Plan dated August 23, 2019,Project No. 770 is submitted without any warranty. How does the Contractor undertake findinginformation that it can rely on related to this plan?

Response: The Construction Safety and Phasing Plan (CSPP) is a document prepared by the airport

operator, that is submitted to and approved by the FAA, as a tool to ensure safety compliance when

coordinating construction activities. The CSPP includes requirements that must be implemented by the

contractor during construction to safely construct the work. The contractor is responsible for preparing

a Safety Plan Compliance Document (SPCD) in accordance with the requirements of the CSPP and

FAA AC 150/5370-2G. The SPCD may be relied upon once approved.

2. Question: Jacobs Runway 17-35 Demolition Construction and Safety Plan dated August 23, 2019,Project No. 770, requires that revised to scope or schedule to the project may necessitate revisions tothe construction safety phasing plan (“CSPP”). Are revisions to the CSPP and approvals accomplishedthrough a Change Order?

Response: Revisions to the CSPP are a matter between the airport operator and the FAA. Such

changes may or may not require revisions to the SPCD, Safety and Phasing Plans, General Notes, or

other contract documents, that may or may not result in the need for a change order being issued.

3. Question: Jacobs Runway 17-35 Demolition Construction and Safety Plan dated August 23, 2019,Project No. 770, Appendix E, Under General Contractor Notes Nos. 3 and 9, who is responsible if theutility company makes an error in flagging and the contractor damages the utility?

Response: There is insufficient information in this hypothetical situation to determine who might be

responsible for damages to a utility. However, the contractor would only be responsible if the utilities

are located on the drawings, markings by the utility owner, or other clear indicator that the utility is in

that location.

CONSTRUCTION

101-3.1 Removal of existing pavement.

The Contractor’s removal operation shall be controlled to not damage adjacent pavementstructure, and base material, cables, utility ducts, pipelines, or drainage structures which are toremain under the pavement.

a. Concrete pavement removal. Full depth saw cuts shall be made perpendicular to the slabsurface. The Contractor shall saw through the full depth of the slab including any dowels at thejoint, removing the pavement and installing new dowels as shown on the plans and per thespecifications. Where the perimeter of the removal limits is not located on the joint and there areno dowels present, the perimeter shall be saw cut the full depth of the pavement. A second sawcut shall be made at 12 inches to 18 inches away from the pavement to remain, so that themajority of the pavement may be removed without damage. The pavement inside the saw cutshall be removed by methods which will not cause distress in the pavement which is to remain inplace. Concrete slabs that are damaged by under breaking shall be repaired or removed andreplaced as directed by the RPR.

The edge of existing concrete pavement against which new pavement abuts shall be protectedfrom damage at all times. Spall and underbreak repair shall be in accordance with the plans. Anyunderlaying material that is to remain in place, shall be recompacted and/or replaced as shownon the plans. Adjacent areas damaged during repair shall be repaired or replaced at theContractor’s expense.

b. Asphalt pavement removal. Asphalt pavement to be removed shall be cut to the full depthof the asphalt pavement around the perimeter of the area to be removed.

c. Removal of Base, Subbase, and/or Subgrade. All stabilized base and/or subbasematerial beneath concrete or asphalt pavements to be removed shall be removed. Stabilized baseshall mean any cemented material, including, but not limited to cement-treated base, bituminousbase, lean concrete base, or soil-cement base.

101-3.2 Preparation of joints and cracks prior to overlay/surface treatment. Remove allvegetation and debris from cracks to a minimum depth of 1 inch (25 mm). If extensive vegetationexists, treat the specific area with a concentrated solution of a water-based herbicide approvedby the RPR. Fill all cracks greater than 1/4 inch (6 mm) wide) with a crack sealant per ASTM




D6690. The crack sealant, preparation, and application shall be compatible with the surfacetreatment/overlay to be used. To minimize contamination of the asphalt with the crack sealant,underfill the crack sealant a minimum of 1/8 inch (3 mm), not to exceed ¼ inch (6 mm). Anyexcess joint or crack sealer shall be removed from the pavement surface.

Wider cracks (over 1-1/2 inch wide (38 mm)), along with soft or sunken spots, indicate that thepavement or the pavement base should be repaired or replaced as stated below.

Cracks and joints may be filled with a mixture of emulsified asphalt and aggregate. The aggregateshall consist of limestone, volcanic ash, sand, or other material that will cure to form a hardsubstance. The combined gradation shall be as shown in the following table.

Gradation

Sieve Size Percent Passing

No. 4 (4.75 mm) 100

No. 8 (2.36 mm) 90-100

No. 16 (1.18 mm) 65-90

No. 30 (600 µm) 40-60

No. 50 (300 µm) 25-42

No. 100 (150 µm) 15-30

No. 200 (75 µm) 10-20

Up to 3% cement can be added to accelerate the set time. The mixture shall not contain morethan 20% natural sand without approval in writing from the RPR.

The proportions of asphalt emulsion and aggregate shall be determined in the field and may bevaried to facilitate construction requirements. Normally, these proportions will be approximatelyone part asphalt emulsion to five parts aggregate by volume. The material shall be poured orplaced into the joints or cracks and compacted to form a voidless mass. The joint or crack shallbe filled to within +0 to -1/8 inches (+0 to -3 mm) of the surface. Any material spilled outside thewidth of the joint shall be removed from the pavement surface prior to constructing the overlay.Where concrete overlays are to be constructed, only the excess joint material on the pavementsurface and vegetation in the joints need to be removed.

101-3.3 Removal of Foreign Substances/contaminates prior to seal-coat and/or remarking.Removal of foreign substances/contaminates from existing pavement that will affect the bond ofthe new treatment shall consist of removal of rubber, fuel spills, oil, crack sealer, at least 90% ofpaint, and other foreign substances from the surface of the pavement. Areas that require removalare designated on the plans and as directed by the RPR in the field during construction.

Chemicals, high-pressure water, or sandblasting may be used. If chemicals are used, they shallcomply with the state’s environmental protection regulations. Removal methods used shall notcause major damage to the pavement, or to any structure or utility within or adjacent to the workarea. Major damage is defined as changing the properties of the pavement, removal of asphaltcausing the aggregate to ravel, or removing pavement over 1/8 inch (3 mm) deep. If it is deemedby the RPR that damage to the existing pavement is caused by operational error, such aspermitting the application method to dwell in one location for too long, the Contractor shall repairthe damaged area without compensation and as directed by the RPR.




Removal of foreign substances shall not proceed until approved by the RPR. Water used for high-pressure water equipment shall be provided by the Contractor at the Contractor's expense.

ACCEPTABLE FILL MATERIALS: POLYPROPYLENE CORRUGATED WALL STORMWATER COLLECTION CHAMBERS

PLEASE NOTE:

1. THE LISTED AASHTO DESIGNATIONS ARE FOR GRADATIONS ONLY. THE STONE MUST ALSO BE CLEAN, CRUSHED, ANGULAR. FOR EXAMPLE, A SPECIFICATION FOR #4 STONE WOULD STATE: "CLEAN, CRUSHED, ANGULAR NO. 4 (AASHTO M43) STONE".

2. STORMTECH COMPACTION REQUIREMENTS ARE MET FOR 'A' LOCATION MATERIALS WHEN PLACED AND COMPACTED IN 6" (150 mm) (MAX) LIFTS USING TWO FULL COVERAGES WITH A VIBRATORY COMPACTOR.

3. WHERE INFILTRATION SURFACES MAY BE COMPROMISED BY COMPACTION, FOR STANDARD DESIGN LOAD CONDITIONS, A FLAT SURFACE MAY BE ACHIEVED BY RAKING OR DRAGGING WITHOUT COMPACTION EQUIPMENT. FOR SPECIAL LOAD DESIGNS, CONTACT STORMTECH FOR

COMPACTION REQUIREMENTS.

4. ONCE LAYER 'C' IS PLACED, ANY SOIL/MATERIAL CAN BE PLACED IN LAYER 'D' UP TO THE FINISHED GRADE. MOST PAVEMENT SUBBASE SOILS CAN BE USED TO REPLACE THE MATERIAL REQUIREMENTS OF LAYER 'C' OR 'D' AT THE SITE DESIGN ENGINEER'S DISCRETION.

NOTES:

1. CHAMBERS SHALL MEET THE REQUIREMENTS OF ASTM F2418-16a, "STANDARD SPECIFICATION FOR POLYPROPYLENE (PP) CORRUGATED WALL STORMWATER

COLLECTION CHAMBERS".

2. CHAMBERS SHALL BE DESIGNED IN ACCORDANCE WITH ASTM F2787 "STANDARD PRACTICE FOR STRUCTURAL DESIGN OF THERMOPLASTIC CORRUGATED WALL

STORMWATER COLLECTION CHAMBERS".

3. THE DESIGN ENGINEER IS RESPONSIBLE FOR ASSESSING THE BEARING RESISTANCE (ALLOWABLE BEARING CAPACITY) OF THE SUBGRADE SOILS AND THE DEPTH OF

FOUNDATION STONE WITH CONSIDERATION FOR THE RANGE OF EXPECTED SOIL MOISTURE CONDITIONS.

4. PERIMETER STONE MUST BE EXTENDED HORIZONTALLY TO THE EXCAVATION WALL FOR BOTH VERTICAL AND SLOPED EXCAVATION WALLS.

5. REQUIREMENTS FOR HANDLING AND INSTALLATION:

· TO MAINTAIN THE WIDTH OF CHAMBERS DURING SHIPPING AND HANDLING, CHAMBERS SHALL HAVE INTEGRAL, INTERLOCKING STACKING LUGS.

· TO ENSURE A SECURE JOINT DURING INSTALLATION AND BACKFILL, THE HEIGHT OF THE CHAMBER JOINT SHALL NOT BE LESS THAN 2”.

· TO ENSURE THE INTEGRITY OF THE ARCH SHAPE DURING INSTALLATION, a) THE ARCH STIFFNESS CONSTANT AS DEFINED IN SECTION 6.2.8 OF ASTM F2418 SHALL

BE GREATER THAN OR EQUAL TO 550 LBS/IN/IN. AND b) TO RESIST CHAMBER DEFORMATION DURING INSTALLATION AT ELEVATED TEMPERATURES (ABOVE 73° F /

23° C), CHAMBERS SHALL BE PRODUCED FROM REFLECTIVE GOLD OR YELLOW COLORS.
