ADDITIONAL SPECIAL CONTRACT REQUIREMENTS

PART 1 GENERAL

1.1 STATEMENT OF WORK

1.1.1 Dredging: The scope of work of the contract is to perform maintenance dredging in Mobile Harbor including disposal of dredged material into the Ocean Dredged Material Disposal Site (ODMDS). The base bid for maintenance dredging will be from Station 244+66 to 267+73 (turning basin), Station 267+73 to 600+00, and Station 1250+00 to 1370+00. A 100ft buffer will be applied to the red-side channel toe of the turning basin (Station 244+66 to 267+73). The buffer area will not be included in the required dredging prism; however, if material is removed/dredged from the 100ft buffer area it will be paid at the contract unit price for dredging.

Optional dredging assignments from Station 9+30 to 32+76, Station 105+00 to 150+00, and Station 164+00 to 212+00 may be included in the contract if funding becomes available and approved by the Contracting Officer (KO).

Should additional areas within Mobile Harbor require maintenance dredging during the contract period, such work may be included under this contract at the discretion of the Contracting Officer. The contractor is to perform such additional dredging in accordance with the same terms, conditions and specifications set forth in this contract.

The scope also includes supplying dredge-related supplies and equipment such as tugs, barges, cranes, attendant plants, and other marine equipment associated with channels and coastal restoration projects.

1.1.2 Dredge Material Disposal: All dredged material will be placed into the Ocean Dredged Material Disposal Site (ODMDS) located approximately 5-miles south of Dauphin Island, Alabama as shown in the contract drawings.

1.1.3 Project Duration and Completion: The work under this contract shall commence upon issuance of the Notice to Proceed and shall be completed within 180 240 calendar days following the Notice to Proceed (NTP).

(a) The Contractor will be furnished with a digital copy of the advertised solicitation, including all contract clauses, drawings, and specifications. Paper copies of the specifications and drawings will be the responsibility of the Contractor. The work shall conform to the

SECTION 01 00 00

technical provisions outlined in the specifications and the contract drawings.

(b) Omissions from the drawings or specifications or the misdescription of details of work which are manifestly necessary to carry out the intent of the drawings and specifications, or which are customarily performed, shall not relieve the Contractor from performing such omitted or misdescribed details of the work, but they shall be performed as if fully and correctly set forth and described in the drawings and specifications.

(c) The Contractor shall check all drawings furnished them immediately upon their receipt and shall promptly notify the Contracting Officer of any discrepancies. Figures marked on drawings shall in general be followed in preference to scale measurements. Large scale drawings shall in general govern small scale drawings. The Contractor shall compare all drawings and verify the figures before laying out the work and will be responsible for any errors which might have been avoided thereby.

(d) The list of drawings and maps provided in the Index Sheet of the Plans for this solicitation are hereby incorporated by reference into these specifications.

NOTE: Refer to the folio of drawings for the index of drawings in this solicitation.

1.4 PHYSICAL DATA

Data and information furnished or referred to below is for the Contractor's information. The Government will not be responsible for any interpretation or conclusion drawn from the data or information by the Contractor.

1.4.1 General: The indications of physical conditions on the drawings and in the specifications are the result of site investigations and surveys.

1.4.2 Location: The work to be done under these specifications is located within the limits of Mobile Harbor federal navigation channel. Work assignments include Station 244+66 to 267+73, Station 267+73 to 600+00 and Station 1250+00 to 1370+00. The Ocean Dredged Material Disposal Site (ODMDS) is located approximately 5-miles south of Dauphin Island, Alabama. Optional dredging assignments are located in the Mobile River at Station 9+30 to 32+76, Station 105+00 to 150+00, and Station 164+00 to 212+00.

1.4.3 Contractor’s Investigation Responsibility: The Contractor should investigate submerged, surface, and overhead structures in the work areas and other locations which may be necessary to traverse. The exact location, depths, and height of submarine cables, pipes, highlines, etc. (as applicable), are not known and it will be necessary for the Contractor to ascertain interference problems and notify the respective owners in advance of dredging operations. The Contractor shall make all arrangements with the respective owners of the structure to assure satisfactory completion of dredging in the vicinity with a minimum interruption of service and shall perform operations in such a manner as will avoid damage to these facilities.

1.4.4 Weather Conditions: The sites of the work are exposed to local disturbances in the Mobile Harbor, which may cause suspension of the work for short unknown periods of time. During tropical hurricanes which may occur from June to November, inclusive, the project channels do not afford a safe refuge for floating plant. There are no unusual currents except during floods, when velocities of 2 to 4 miles per hour may be expected; however, the Contractor should investigate all sites of work and determine for themself the requirements of the work. Under ordinary conditions, the Mean Tidal Range is 1.2 feet. The working season extends over the entire year. Tides in Mobile Harbor are affected by extended periods of strong north or south winds.

1.4.5 Transportation Facilities: The work areas are accessible by water via the Gulf Intracoastal Waterway and the Gulf of America. The Contractor shall investigate any limitations imposed by bridges or other structures on water access to the project site. Highway access (Federal, state, and local) is available to the near vicinity of all work areas. Rail and highway transportation is available to Mobile, Alabama. Water transportation is available to the site of the work. The Contractor shall make their own investigation of available roads for transportation, load limits for bridges and roads, and other road conditions affecting the transportation of materials and equipment to the work sites.

1.4.6 Channel Traffic: The traffic using the Mobile, Alabama Shipping Channel is considered to be a combination of heavy and large commercial vessels, and various sized recreational craft, respectively. The type of traffic consists of general container ships, bulk carriers, fuel tankers, tow boats, Navy ships, charter fishing boats, passenger boats, and pleasure craft.

CAUTION: When navigation conditions become hazardous due to inclement weather (fog, storm, etc.) or other circumstances, the Contractor shall maintain appropriate communication with project traffic. The Contractor shall particularly comply with all U.S. Coast Guard regulations pertaining to proper activation of fog (and any other) signaling devices (sound, light, etc.).

1.4.7 Obstruction of Navigation Channels: The Government will not undertake to keep the work areas and navigation channels free from vessels or other obstructions, except to the extent of such regulations, if any, as may be prescribed by the Secretary of the Army, in accordance with the provisions of Section 7 of the Rivers and Harbors Act approved 8 August 1917. The Contractor will be required to conduct the work in such manner as to obstruct navigation as little as possible, and in case the Contractor's plant so obstructs any navigation channel as to make difficult or endanger the passage of vessels, said plant shall be promptly moved on the approach of any vessel to such an extent as may be necessary to afford a practicable passage. Upon the completion of the work the Contractor shall promptly remove their plant, including ranges, buoys, piles, and other marks placed by them under the contract in navigable waters or on shore.

1.5 TIME EXTENSIONS

Notwithstanding any other provisions of this contract, it is mutually understood that the time extensions for changes in the work will depend upon the extent, if any, by which the changes cause delay in the completion of the various elements of construction. The change order granting the time extension may provide that the contract completion date will be extended only for those specific elements so delayed and that the remaining contract completion dates for all other portions of the work will not be altered and may further provide for an equitable readjustment of liquidated damages under the new completion schedule. Change orders involving time extensions must be obtained in writing from the Government's Representative.

1.12 FINAL EXAMINATION AND ACCEPTANCE

As soon as practicable (within 14 calendar days or less if agreed to by the Contracting Officer) after completion of the entire work or any designated section thereof (if the work is divided into sections), as in the opinion of the Contracting Officer, the work in this section will not be subject to damage by further operations under the contract, such work will be thoroughly examined at the cost and expense of the Government by sounding or by sweeping, or both, as determined by the Contracting Officer, for determination of ACCEPTABILITY of PERFORMANCE by the Contractor. In order to ensure a feasible “face” of material for efficient dredging operations, work sections will be considered accepted if 90% of the material from the required dredging prism is removed;

however, the Contractor should make an attempt to dredge uniformly to not leave shoals and/or lumps. Should any shoals, lumps, or other lack of contract required dredging prism depth, width, or slope beyond the 90% acceptance criteria be disclosed by the Government’s examination, the Contractor will be required to remove said shoals by dragging or dredging the affected surface until the acceptable condition is corrected. Payment will be based on before-dredging (BD) and after-dredging(AD) quantity computations. Payment quantities and acceptance will be based on high frequency survey data run on 100-ft intervals including points of intersection. The contract drawings include typical sections showing the existing channel dimensions, the advanced maintenance, and the allowable overdepth. If the unacceptable shoal (work) area(s) of the channel bottom/slope is soft and the shoal (work) area(s) is small and forms no material obstruction to navigation, the removal of such shoal(s) may be waived at the discretion of the Contracting Officer. If re-dredging is required to correct the unacceptable work, the dredging will be paid at the current unit price for dredging, however, the maximum payment quantity (original and re-dredgings) will be the original computed pay quantity in the required dredging prism (plus any applicable allowable overdepth quantity, as applicable) based on the original before-dredging surveys. The Contractor or their authorized representative will be notified when soundings and/or sweepings are to be made and will be permitted to accompany the survey party. When the original or unacceptable area(s) is found to be in satisfactory condition, it will be accepted finally. Should more than two sounding or sweeping operations by the Government over an area be necessary by reason of work for the removal of unacceptable shoals disclosed at a prior sounding or sweeping, the cost of such third and any subsequent sounding or sweeping operations will be charged against the Contractor at the rate of $2,500.00 per day for each day in which the Government (or Government A-E Contractor) plant is engaged in sounding or sweeping and/or is enroute to or from the site or held at or near the said site for such operations.

For the purpose of acceptance, the work to be done will be divided into approximate 2,000-foot sections as defined below:

Dredging Reach No. From Station To Station 1 (partial) 244+66 260+00

2-18 260+00 600+00

19-24 1250+00 1370+00

Optional dredging assignments will be divided into approximate 2,000-foot sections as defined below:

Dredging Reach No. From Station To Station

Option 1:

1 (partial) 9+30 22+00

2 (partial) 22+00 32+76

Option 2:

1 (partial) 105+00 110+00

2-3 110+00 150+00

Option 3:

1 (partial) 164+00 172+00

2-3 172+00 212+00

1.12.1 Final acceptance of the whole or part of the work and the deductions or corrections of deductions made thereon will not be reopened after having once been made, except on evidence of collusion, fraud, or obvious error, and the acceptance of a completed section shall not change the time of payment of the retained percentages of the whole or any part of the work.

1.12.2 After acceptance by the Government, of the whole or part of the work, but before the Contractor has effected demobilization, should any shoals, lumps, or other lack of required contract depth be disclosed by an examination made by the Government, the Contractor may be requested to remove any such shoal by using the on-site dredging plant and process, to be paid at the original contract rate for dredging in this location.

This additional dredging is subject to a supplemental agreement under the contract and is only activated by the Contracting Officer (and if funds are available).

1.12.3 Shoaling in the dredging prism, which occurs in the whole or part of the work not yet offered by the Contractor as candidate for acceptance examination by the Government, is the responsibility of the Contractor (notwithstanding other clauses or provisions of this contract).

The Contractor should order the accomplishment of all the work of this contract in such a manner that causes the least exposure to such in-process shoaling.

1.13 PERFORMANCE EVALUATION OF CONTRACTOR

As a minimum, the Contractor's performance will be evaluated upon final acceptance of the work. However, interim evaluation may be prepared at any time during the contract performance when determined to be in the best interest of the Government.

The evaluation will be completed in the Contractor Performance Assessment Reporting System (CPARS), and the Contractor will be rated either exceptional, very good, satisfactory, marginal, or unsatisfactory in the areas of Quality, Schedule, Cost Control, Management, Small Business, Regulatory, and Other Areas. The Contractor will be advised of any unsatisfactory rating, either in an individual element or in the overall rating, prior to completing the evaluation, and all Contractor comments will be made a part of the official records. Performance Evaluation Reports will be available to all DOD Contracting offices for their future use in determining Contractor responsibility, in compliance with DFARS 36.201(c)(1).
