All requirements with respect to the Contractor's use of the lock guide wall are in the Contract Specifications, Section 01 35 13, Paragraph

1.5.1.

LDC CONSTRUCTION (Received 8/31/17)

1. At the pre‐bid it was mentioned that the blacktop walkway from the parking lot over to the seawall was only to be used for light duty equipment. What is the maximum weight that can go across or down that path?

The first sentence of Note 2 on Contract Drawing Sheet C‐101 has been revised as follows: "ACCESS ACROSS THE CAUSEWAY IS LIMITED TO ONLY

PEDESTRIAN TRAFFIC AND LIGHT‐WEIGHT VEHICLES WITH A MAXMUM

WEIGHT OF 6000 POUNDS WHEN LOADED." A PDF file of the revised

Contract Drawing Sheet C‐101 is provided.

7. In addition to the weight restriction (300lbs/sf) to be used on the lock for transloading equipment, are there any other location or equipment‐ type restrictions for use of the lock as a temporary work platform.

4. Please provide details related any turbidity monitoring requirements or water quality standards that could impact operations.

5. Please provide any boring logs collected for the material being dredged and placed into North Pond.

6. What specific requirement – if any – exist for the use of divers?

The .xyz file "Existing North Pond.xyz" that was used to create the existing contours on Contract Drawing Sheet C‐101 is provided.

The Autocad file "Existing Contours.dwg" and the Microstation file

"Existing Contours.dgn" that was used to create it are provided.

The following sentence has been added to the end of paragraph 1.3.1.1:

"The 60% payment will be made after the initial mobilization during calendar year 2018 and the 40% payment will be made after the final demobilization at the end of calendar year 2018. " See amended specifications.

The requirement to install a turbidity curtain on the North Pond side of the opening in the existing stone dike has been added as an option bid item. For the added turbidity curtain requirements, see the amended

Contract Specifications, Section 01 22 00.00 02, Paragraph 1.3.6 and

Section 01 35 13 Paragraph 1.3.1 b. The dredging contractor, this fall, will install a turbidity curtain on the North Pond side of the existing concrete box culvert. Contract Specifications Section 01 22 00.00 02, Paragraph 1.3.1.1 and Section 01 35 13, Paragraph 1.3.1 have been revised to require the Unity Island Ecosystem Restoration contractor to maintain this turbidity curtain, and replace it (if functionality cannot be maintained), throughout the duration of the contract and remove as directed.

No borings were obtained in the Buffalo River dredging area. Five (5) surface grab samples (BRD17‐1 through BRD17‐5) were obtained using

Ponar dredge. Locations are shown in the plan as part of this amendment . Sieve analysis was performed on only 1 sample (BRD17‐1) as this sample was the only one that had gravel/sand. Gradation (sieve) and Atterberg limits were performed on these samples with results summarized in the table and figure that is attached to the original solicitation. All other samples were fine grained (silt & clay) as shown in the summary table that is attached to the original solicitation.

Photographs of teste performed by USACE personnel are also part of this amendment.

2. Please provide existing AutoCAD drawings of North Pond at Unity

Island.

3. Section 01 22 00, 1.3.1.1 states that costs associated with mobilization and demobilization will be paid as one line item. This section additionally acknowledges that multiple mobilization/demobilizations may be required as it relates to crews returning for additional planting seasons.

Please clarify whether after the initial mobilization the successful contractor will be compensated for 60% of Bid Schedule Item 1. If that is not the case, please detail how the 60% compensation for mobilization is spread among the mobilizations, and further define “mobilization”.

The definition of "mobilization" is:

'The movement of any Contractor plant and equipment to be used to complete the work required .'

1.4.8.1 Payment

Payment will be made at the contract unit price ton in place for the following items, which will constitute full compensation for providing all plant, labor, and materials, and performing all operations required to complete the work as specified herein, and as shown on the drawings. All stone materials must be new quarried materials. Placement of new stone in the opening is paid for under the line item "Opening In Existing Stone Dike: Construction and Associated Work".

1.4.8.2 Measurement

Stone will be measured for payment by the ton (2,000 pounds) by weighing each truckload to the nearest 0.1 ton, and the final quantity of the whole sum will be rounded to the nearest whole ton. Surveys will not be used for measurement purposes other than to determine excess quantities to deduct from payment. The stone will be measured for payment by being weighed on approved scales before being placed in the work. Quarry weights will not be accepted. Scales must be of sufficient length to permit simultaneous weighing all axle loads and must be inspected, tested and sealed as

SECTION 01 22 00.00 02 Page 1009 directed to assure accuracy with 0.5 percent throughout the range of the scales. The scales, located at the site of the work, must be certified as to accuracy by an acceptable scales company representative prior to weighing any stone. Scales will be checked and certified before stone hauling and rechecked and recertified whenever a variance is suspected.

The Contractor must furnish the scales. If commercial scales are readily available in close proximity 10 miles of site of work, the Contracting Officer may approve the use of the scales. The stone must be weighed in the presence of the Government representative. The Contracting Officer may elect to accept certified weight certificates furnished by a public weighmaster in lieu of scale weights at the jobsite. New stone materials will be measured for payment will be by the ton (2,000 pounds) of material acceptably placed in the work. as determined by carrier displacement or certified scale weight tickets, as approved by the Contracting Officer.

Material placed beyond the tolerance limits will not be paid for. Any length of repair not completed will all types of stone specified will not be paid for The method of determining the quantity of material placed beyond tolerance limits will be made in accordance with paragraph, "Determination of Excess Stone" and the use of the conversion factors outlined in paragraph "FACTORS USED FOR CONVERTING IN-PLACE VOLUME TO WEIGHT." Any material wasted or used by the Contractor for other purposes and any material not placed in the required work in accordance with the requirements of the specifications and drawings will not be measured or paid for.

1.4.8.2.1 Method of Determining Weight with Delivery by Vessel or Barge

A Bill of Lading must accompany every vessel or barge loaded at a quarry to indicate indicating the origin, specific type of stone and draft/freeboard readings on the vessel or barge. Only one type of stone will be allowed per vessel or barge.

1.4.8.2.1.1 Displacement Gauges

If stone is delivered by vessel or barge, the carrier must, prior to use in connection with this work, be fitted by the Contractor at its own expense with gauges or such other facilities for determining displacement as may be required by, or be satisfactory to, the Contracting Officer. Carriers, which owing to their model or other cause cannot be accurately gauged for displacement, must not be used on this work. Gauges must be graduated to the tenth of a foot, or to other suitable unit approved by the Contracting Officer. They must be six (6) in number and must be located as follows:

two (2) near each end on opposite sides and two (2) amidship on opposite sides. The gauges must be attached solidly to the hull itself, and wherever practicable, must be located inside the hull. If located inside the hull, provisions must be made for the free passage of the outside water to a vertical tube and for the ready measurement of the depth of the water within the tube. If located outside on wood hulls, the gauges must be protected by solid fenders or be recessed into the planking, or if on steel hulls, the gauge marks may be placed directly on the plates and identified by punch marks. Gauges must be so placed that their zeros are below water when the carrier is in its normal trim, light and free from water. The installation of the gauges must be subject to the approval of the Contracting Officer. The Contracting Officer must be allowed to be present at the installation of gauges and (s)he must be notified a minimum of five

(5) days prior to installation of gauges.

SECTION 01 22 00.00 02 Page 1010

1.4.8.2.1.2 Gauging Tables

To facilitate the determination of the weight of each load, a gauging table for each carrier employed must be prepared by an accredited agent satisfactory to the Contracting Officer. The gauging table must show the cargo weight, in tons of 2,000 pounds, for each unit of measurement of the draft. If the lines of the carrier are such that the cubic feet of displacement for each measured unit of draft can be accurately calculated, the gauging table must be based upon the data, using 62.4 pounds as the weight of one (1) cubic foot of water. If the lines of the carrier to be gauged are such as to render impracticable the preparation of the gauging table by the above described method, the weight for each unit of draft must be determined by measurement of displacement by actually loading stone of known weight and the weight thus obtained must be entered in the table for use in subsequent gauging. If alterations are made in any carrier which will affect the accuracy of the gauging table, after it has been prepared, or if otherwise deemed necessary at any time by the Contracting Officer, the carrier must be remeasured, and a new gauging table prepared. The Contractor must furnish such labor and material as may be required in collecting data for the preparation of gauging tables, and the cost of the labor and material so furnished must be included in the contract unit price per ton for the items as applicable. Existing stone placed in lieu of new stone is excluded from measurement for payment for new stone.

1.4.8.2.1.3 Reading of Draft Gauges

Readings to determine the draft will be taken before and after unloading.

The difference in tonnage found between loaded and light, will be used to determine the net weight to be paid. The draft must be determined from the average of all six (6) readings, weighting the readings of the middle gauges at double those of the end gauges. (G1 + G2 + 2xG3 + 2xG4 + G5 + G6) divided by 8 = average draft. The Contracting Officer must be present at all draft gauge readings.

1.4.8.2.1.4 Uniform Loading

The carrier must be so loaded as to cause uniform submergence. The increase in draft on the middle gauges, as a result of the load, must not differ by more than 0.5 feet from each other and that between any bow gauges and any stern gauges must not differ more than 1.5 feet from each other. If such is not the case, the Contractor must trim the carrier by shifting the stone until this limit is reached, before the stone will be accepted. If, however, the carriers proposed to be used by the Contractor are so built that they cannot be loaded as prescribed, and yet can be calibrated accurately for displacement under varying loads, such other method of determination of displacement as may be approved by the Contracting Officer may be used.

1.4.8.2.1.5 Readings in Still Water

All measurements for determining gauging table data and for load depths must be made in still water as close to the work as is possible. The Contractor is required to place the carriers where such measurements can be accurately made.

1.4.8.2.1.6 Leaks

All carriers used in transporting stone must be free of leaks such as would render accurate gauging difficult. Facilities for inspecting the hold of

SECTION 01 22 00.00 02 Page 1011 each carrier to determine whether leakage is occurring must be provided.

Each carrier must also be provided with adequate pumping facilities, and if water is found to be accumulating in the hold, the carrier must be pumped dry before each gauging, both before and after unloading.

1.4.8.2.1.7 Variations During Unloading Operations

Lightening by pumping or by transfer of crews or supplies will not be permitted while stone is being discharged. Should any lightening become necessary, the unloading of stone must be suspended and the draft readings taken before and after lightening, or, upon approval of the Contracting Officer's onsite representative, other record made of the amount removed.

The amount determined by the Contracting Officer, as having been removed must be excluded from the net tonnage paid.

1.4.8.2.1.8 Carrier Designations

Each carrier must be plainly marked by a distinctive number, letter, or name, which must not be changed or given to any other carrier during the contract period.

1.4.8.2.1.9 Verification of Measurements

The readings, other data, and calculations from which the gauging table and the tonnage are determined will be open to verification by the Contractor and must be subject to the approval of the Contracting Officer. The Contractor is invited to be present in person or to be represented by an authorized agent during the measuring of carriers. When the displacements of the carriers are determined or redetermined, a record of allowed displacement for quantity determination will be sent to the Contractor. If the Contractor protests within five (5) days, the carrier will be remeasured and the Contractor must be present in person or be represented by an accredited agent so that correct measurements can be agreed upon.

The Contractor will be given the weight of each load, as it is determined.

Failure to protest within five (5) days will be taken as equivalent to expressing satisfaction with the measurements and weight of stone determined by the Contracting Officer.

1.4.8.2.1.10 Carriers Not Measured

In case any stone is delivered by carriers not measured for displacement and marked as herein described, the Contractor must, with the Contracting Officer's approval and at the Contractor's expense, furnish means for properly and conveniently weighing such stone at the work site.

1.4.8.2.2 Method of Determining Weight with Delivery by Truck

The method of measurement for determining the weight of stone materials delivered by truck must be certified weigh bills provided by the Contractor at the job site from either on-site or off-site scales. Weigh bills and the scales used for weighing of trucks and materials contained therein must, unless otherwise approved by the Contracting Officer, conform to the following requirements:

a. Scales must conform to the requirements of the National Bureau of Standards (NBS) Handbook NIST HB 44. The tolerance applications of the Handbook, as applicable to under registration and over registration and to tests involving digital indications or representations, must apply.

The manufacturer may not use a scale for weighing a load totaling more

SECTION 01 22 00.00 02 Page 1012 than the nominal capacity marked on the scale. Any portion of the load in excess of the nominal scale capacity will not be considered for payment.

(1) The accuracy of the scale must be checked. When a State scale inspector is not immediately available for checking the scale, the Contractor may, at its own expense, secure a check from a local official sealer of weights and measures, or the Contracting Officer, may give tentative approval, based on check truckloads weighed on other scales which bear an official seal placed in the current calendar year.

b. The total weight of a single highway vehicle must be weighed as a single draft and may not be determined by adding together the results obtained by separately weighing each end of such vehicle, except that weighing of a coupled combination may be determined without uncoupling under the following conditions:

(1) The brakes are released.

(2) There is no tension or compression on the drawbar.

(3) The approaches are straight and in the same level plane as the scale platform.

(4) The approaches are paved at least fifty (50) feet in each direction with a seal coat or higher type surfacing.

(5) The approaches are of sufficient width and length to ensure level positioning of vehicles during the weighing operation.

c. When a printout system is employed on a platform or surge bin scale, it must be equipped with a printer, which must print the following information on a triplicate ticket for each truckload:

(1) Time.

(2) Date.

(3) Sequential ticket number (may be preprinted on ticket).

(4) Gross Weight.

(5) Tare Weight (trucks must be tare weighed at least twice daily).

(6) Net Weight.

(7) Net accumulated job daily total.

(8) Truck identification number (or license plate number).

d. The system must be so interlocked as to allow printing only when the scale has come to a complete rest.

1.4.8.2.2.1 Scales

For scales not equipped with the print-out system, as stated above, weigh bills must contain the same or equivalent data as specified for the

SECTION 01 22 00.00 02 Page 1013 print-out system. Weigh bills, including printouts, must be certified by the signature of the scale operator, which must attest that the information shown on the weigh bill is correct and is the weight(s) observed on the scale at the time of weighing. Each weigh bill must also be certified by the Contractor attesting that the entire load was properly placed in the work, and must show the time and date of weighing and the time and date of unloading. Each truck must be plainly marked by a distinctive number, letter, or name, which must not be changed or given to any other truck during the contract period. The Government reserves the right to periodically inspect the weighing operations at the scales. Copies of waybills and delivery tickets must be submitted during the progress of the work with the Contractor's daily Quality Control Reports. Before the final statement is allowed, the Contractor must file certified waybills and certified delivery tickets for all stone actually used.

1.4.8.2.2.2 On-Site Scales and Weigh Scale Certification

On-site scales must be certified by the applicable local weights and measures regulating agency and must be as approved by the Contracting Officer. Scales must be of the recording type and of the size required to weigh the materials and containers or vehicles. The scale must include housing for the instruments and scale operator, with heat, lighting and ventilation.

1.4.8.2.3 Determination of Excess Stone

All stone permitted by the Contracting Officer to remain outside the limits and tolerances of the cross sections of the structure, except variations so minor as not to be measurable, will be deducted from the quantity of new stone to be paid for. Weight of excess stone will be determined from the cross sections obtained by the method provided for in paragraph "Final Surveys," on the basis that the cubic feet of volume (including voids) for each type of stone listed in paragraph "FACTORS USED FOR CONVERTING IN-PLACE VOLUME TO WEIGHT", is equal to one (1) ton or 2,000 pounds for the bulk specific gravity and percentage of voids shown. If the bulk specific gravity of the stone furnished or the percentage of voids is other than as listed below, the cubic feet of volume equaling 2,000 pounds must be recomputed as described in paragraph "Revision of Bidding Schedule Quantities". Should any excess stone be disclosed above the tolerance line as defined in paragraph, "Tolerances," its volume will be computed by the average end area method, based on the cross sections in the following manner. The average end area of excess stone above the tolerance line for two (2) successive cross sections, multiplied by the distance between the cross sections will be accepted as the volume. The Contractor will not be required to remove such excess stone and deductions for the weights thereof will be made from contract payments for new stone. In addition to the above, stone which has been delivered to the site and has been lost or wasted or otherwise not properly incorporated into the final required work, must be deducted from the quantity to be paid for.

1.4.8.2.4 Surveys for Excess Volume

Survey work and measurements required for determination of excess volume computations for stone materials must be performed by the Contractor in the presence of the Government's on-site representative, unless the requirement for the Government's presence is waived. Additional cross sections, elevations and soundings may be taken if determined necessary by the Government's on-site representative. Prior to performing any work under this Section, the Contractor must coordinate all operations with the

SECTION 01 22 00.00 02 Page 1014

Government's on-site representative so that excess volume surveys will be made at the appropriate time. Stone quantity computations must be based entirely upon weights of new stone as determined from carrier displacement or certified scale weight tickets. Existing stone placed in lieu of new stone from off-site sources is excluded from measurement for payment.
