1.2 NOTES

NOTE 1: Offerors shall furnish unit prices for all items listed on the schedule of bid items, which require unit prices. If the offeror fails to insert a unit price in the appropriate blank for required items, but does furnish an extended total or an estimated amount for such items, the Government will deem his unit price to be the quotient obtained by dividing the extended estimated amount for that line item by the quantity. IF THE OFFEROR OMITS BOTH THE UNIT PRICE AND THE EXTENDED

ESTIMATED AMOUNT FOR ANY ITEM, THE BID WILL BE DECLARED NONRESPONSIVE.

In the event there is a difference between a unit price and the extended total, the unit price will be held to be the intended bid. If the offeror shows only the total price but fails to enter a unit price, the total divided by the estimated quantity will be held to be the intended unit price.

Any offer price for items indicated above which are unbalanced as to price may be rejected as non-responsive. An unbalanced offer is one which is based on price significantly less than cost for some work and price which is significantly overstated for other work.

Award will be made as a whole to one offeror.

AC = Acre CF = Cubic Feet CY = Cubic Yard DH = Miles EA = Each FC = 1000 Cubic Feet FT = Foot HF = 100 Feet HH = 100 Cubic Feet HL = 100 Linear Feet HR = Hours HS = 100 Square Feet HY = 100 Yards LB = Pound LF = Linear Foot LH = Labor Hour JA = Job (lump sum) LY = Linear Yard MO = Months SB = Square Mile SF = Square Foot SQ = Square SY = Square Yard TL = 1000 Linear Feet TN = Net Ton UN = Unit YD = Yard YL = 100 Linear Yards YM = Cubic Yards Per Mile

All quantities are estimated except where unit is given as "JA" or "EA".

NOTE 2: If an offer or modification to an offer based on unit prices is submitted and provides for a lump sum adjustment to the total estimated cost, the application of the lump sum adjustment to each unit price, including lump sum units, in bid schedule must be stated, or, if it is not stated, the offeror agrees that the lump sum adjustment shall be applied on a pro rata basis to every unit price in the bid schedule.

NOTE 3: Offerors are cautioned to read Contract Clause entitled "DFAR 252.204-7004, Alternate A, System for Award Management (FEB 2014) located

DOCUMENT 00 41 00.00 11 Page 5

SECTION 00700 - CONTRACT CLAUSES

The following have been modified:

52.211-10 COMMENCEMENT, PROSECUTION, AND COMPLETION OF WORK (APR 1984)

The Contractor shall be required to (a) commence work under this contract within 10 calendar days after the date the Contractor receives the notice to proceed, (b) prosecute the work diligently, and (c) complete the entire work ready for use not later than 545 calendar days for the base bid, 60 additional calendar days for option 1, and 130 additional calendar days for option 2 after the date of receipt by him of notice to proceed. The time stated for completion shall include final cleanup of the premises. If either option is exercised at the same time as the base award, the Contractor shall complete the options concurrently within the base contract time.

Due to the likelihood that river stages above 8 ft. to 10 ft. on the Holly Island gage (EL. 258 ft. to 260 ft.) may prevent channel cleanout excavation operations from continuing, river stages above those elevations, provided that they do impact the work in the opinion of the COR, will be treated like sever weather days.

(End of clause)

SECTION 00800 - SPECIAL CONTRACT REQUIREMENTS

The following has been modified:

Section 1.5: LAYOUT OF WORK

Paragraph d (4) & (5)

(4) Quantity Survey Method for Channel. Unless otherwise authorized by the Contracting Officer, the cross-section method shall be used to obtain the topography. Cross-sections shall be conducted to obtain the topography of constructed features including, but not limited to: height, width, grades, and slopes of excavation and/or embankments including berms and excavated material disposal areas. Individual cross-sections will depend upon the terrain but for pre-construction shall not exceed 500' intervals in straight segments and shall not exceed 250' intervals in curves and/or transitions as identified by the Contracting Officer. For post-construction surveys an interval of 500' is acceptable. The Pre-Construction Surveys and the Post-Construction Surveys shall be submitted in MicroStation.dgn format. Observations shall be recorded at all breaks in slopes with a maximum distance of 25' between observations. Cross sections shall be conducted at 90-degrees to the channel and at sufficient width to extend 50-feet beyond the limits of work or to the designated R.O.W. Annotated cross-sections shall be created and included in DGN format at 1"=10'. For work along the right bank, at a minimum, the cross sections shall extend from the existing top left bank to 50' past the proposed landside toe of the EME or 50' past the proposed top right bank whichever comes last. The annotated cross-sections shall indicate the Baseline; the theoretical grades and slope-lines as specified; and the actual grades and slope lines as constructed. The contractor shall plot cross sections from the survey data to visually depict the grade and sections obtained. The contractor shall use this survey data to develop the as-built drawings. During/or post-construction survey data shall be provided at the Contracting Officer's request.

(5) Quantity Survey Method for EME Removal. Unless otherwise authorized by the Contracting Officer, the cross-section method shall be used to obtain the topography of the existing EME. Cross-sections shall be conducted to obtain the topography of existing and constructed features including, but not limited to: height, width, grades, and slopes of excavation and/or embankments including berms and disposal/storage areas. Individual cross-sections will depend upon the terrain but for pre-construction shall not exceed 500' intervals in straight segments and shall not exceed 250' intervals in curves and/or transitions as identified by the Contracting Officer. For post-construction surveys an interval of 500' is acceptable.

The Pre-Construction Surveys and the Post-Construction Surveys shall be submitted in MicroStation.dgn format. Observations shall be recorded at all breaks in slopes with a maximum distance of 25' between observations. Cross sections shall be conducted at 90-degrees to the embankment and at sufficient width to extend 50-feet beyond the limits of work or to the designated R.O.W. Annotated cross-sections shall be created and included in DGN format at 1"=10'. The annotated cross-sections shall indicate the Baseline; the theoretical grades and slope-lines as specified; and the actual grades and slope lines as constructed. The contractor shall plot cross sections from the survey data to visually depict the grade and sections obtained. The contractor shall use this survey data to develop the as-built drawings. During/or post-construction survey data shall be provided at the Contracting Officer's request.
