e. Progress updating.  


(1) The Contractor and CO's representatives shall meet monthly at the Government project office at a time mutually agreed upon by both parties for the express purpose of reviewing the actual progress made to date on the contract work as shown in the current schedule update. The review shall focus on the dates activities were actually started and completed and the remaining duration for each activity started but not completed during the period. In addition to the above, changes in logic and schedule shall be discussed and mutually agreed upon. Upon completion of the progress review meeting, the Contractor shall revise the update to reflect any changes mutually agreed upon at the review meeting.


(2) The Contractor shall report the current project status to the COR by providing the following diagrams, reports, tables, and graphs.


(a) A narrative report specifically stating the status of the project in terms of total float. If negative float exists, specific actions and conditions shall be cited which caused the "behind schedule" condition and the Contractor shall provide a course of action to complete the project within the delivery time specified in the contract. The report shall also include the following:


(aa) A listing of Contractor initiated changes to the current detailed logic diagrams or schedule stating the reason for the action taken. The Government reserves the right to disapprove Contractor initiated changes to the current detailed logic diagrams and schedule which negatively impact any Government action which was initiated on the basis of the current detailed logic diagrams or schedule.


(bb) Unresolved issues relating to the Construction Program.


(b) Updated total float report.


(c) 60 day look ahead report which shall be a listing of all activities or milestones which are scheduled to start, finish or continue during the next 60 day period.


(d) Updated Construction Program database which shall be submitted in the format and media as specified in subparagraph d. of this paragraph.


f. Time impact evaluation (TIE).  


(1) TIE shall be used by the COR in determining if a time extension or reduction to the contract milestone dates is justified. The Contractor shall provide a TIE to the COR for any contract change, e.g., change order, proposed modification, or value engineering proposal. The Contractor shall also provide a TIE to the COR for any delay to support the Contractor’s request or claim for an equitable adjustment to the contract.


(2) A TIE is applicable whether the Contractor's current scheduled milestone dates are the same as, earlier, or later than those required under the contract. Changes, additions, or deletions to activities; activity durations; or activity time frames shall not automatically mean that an extension or reduction of contract time is warranted or due the Contractor. Time extensions for performance shall be considered only to the extent that the Contractor's current scheduled milestone dates exceed the contract milestone dates. Float is not for the exclusive use by or benefit of either the Government or the Contractor.


(3) TIE shall be performed using the data available in the current detailed logic diagrams and schedule.


(a) Each TIE shall demonstrate where the Contractor proposes to incorporate the change or delay in the current schedule update. The schedule shall show the current activity logic relationships for all activities directly affected by the change or delay, and the proposed activity logic relationships due to the change or delay highlighting the added, changed, and deleted activities. For all activities directly affected by the change or delay, the current and proposed activity description; type and quantities of major pieces of equipment, principal manpower, placing material; duration; and earnings shall be provided with the TIE. A narrative shall be provided containing the rationale used in developing the proposed logic relationships and activity data.


(b) The TIE shall be based on the status of work and the available float at the time the COR directs or proposes a change to the work, the Contractor submits a value engineering proposal, or when a delay occurs.


(4) Following the Contractor's receipt of an executed contract modification, the activity data and logic relationships stipulated in the modification shall be incorporated into the schedule during the next scheduled progress update.


(5) The Contractor shall prepare a single TIE for all modifications issued after NTP and prior to approval of the revised baseline schedule. The TIE shall be submitted with the first progress update.


g. Payment for construction program. – No direct payment by a separate bid item shall be made to the Contractor for developing, maintaining, and using the Construction Program. The cost for developing the detailed logic diagrams and baseline schedule shall be included in the lump sum price bid for mobilization and preparatory work. The cost of maintaining, updating, and using the construction program shall be included as an element of the Contractor's overhead.


1.1.4 LAYOUT OF WORK AND QUANTITY SURVEYS


a. General.   The Government has established the primary control to be used for establishing lines and grades required for the work.


Primary control consists of bench marks and horizontal control points established at the site of the work. Before beginning work, the Contractor shall check and verify all control points established by the Government and shall advise the Government in writing that the points are acceptable or, if they are not acceptable, the reasons therefore.


The Contractor shall be responsible for maintaining and preserving all control points established by the Government until authorized to remove them.

The Contractor shall furnish the services of experienced construction surveyors. All Contractor survey work shall be under the direction of a surveyor or engineer who is qualified to supervise the work required by this paragraph. The Contractor shall furnish to the Construction Engineer the resume of the surveyor or engineer responsible for the surveys showing appropriate construction survey and engineering experience. This experience shall include a minimum time of 2 years in responsible charge of construction surveys relating to water distribution systems or similar types of construction surveys. The number of surveying personnel required will vary with the workload; however, the Contractor shall maintain sufficient qualified survey personnel to perform the work required by this paragraph.


All survey work performed by the Contractor shall be subject to field and office review by the COR.


b. Layout of work.   From the primary control points, the Contractor shall lay out the work by establishing all lines and grades at the site necessary to control the work and shall be responsible for all measurements that may be required for the execution of the work, to the location, limit marks, and tolerances prescribed in these specifications or on the drawings.


The Contractor shall perform all layout surveys, final quantity surveys, and all intermediate surveys required for the control and completion of the work. All borrow areas require complete cross sections by the Contractor prior to excavation and after use, yet prior to shaping the area to conform to adjacent natural contours.


The Contractor shall place and establish or replace such additional stakes, markers, or make complete surveys as may be necessary for control, intermediate checks, and guidance of the Contractor's construction operations.


Prior to beginning any phase of the survey work, the Contractor shall submit to the Construction Engineer a plan for establishing lines and grades for control of the work, including the Contractor's plans and timetable for submitting data to the Government.


The data shall include, but are not limited to, original cross sections on structural excavations, roads, pipelines, and appurtenant structures, and final cross sections for all completed features.


c. Quantity surveys.   The Contractor shall perform all necessary surveys to compute the quantities of work performed or finally in place. The Contractor shall obtain original terrain data and perform the computations to determine the final quantities of work and materials based on this original terrain data and design lines and grades or quantity survey measurements. All computations will be subject to review by the COR. The Contractor will be required to submit detailed computations, if directed by the COR. The COR may also direct the Contractor to perform surveys of the final ground, regardless of what the payment paragraphs state.


All surveys performed for measurement of final quantities of work and material shall be subject to the approval of the COR. Unless waived by the COR in each specific case, quantity surveys made by the Contractor shall be made in the presence of the COR. The Contractor shall notify the COR 24 hours in advance of the performance of any quantity survey.


The Contractor shall make such surveys and computations as are necessary to determine the quantities of work performed or placed during each period for which a progress payment is to be made. Such quantities shall include excavation, backfill, and all other items included in the schedule for which payment is to be made. The Contractor shall furnish a copy of the quantity computations and an itemized statement for each progress payment period.


d. Contractor surveys.   In accordance with the requirements of subparagraphs b. and c., the Contractor shall perform the following:


(1) Stake station alignment each 50 feet on tangent and each 25 feet on curves.


(2) Slope stake each 50 feet on tangent, each 25 feet on curves, and restake every 10 feet in elevation.


(3) Stake out all structures and perform all checkouts prior to and during construction.


(4) Blue tops for road, every 50 feet on tangent and 25 feet on curves.


(5) Take cross sections as needed and on all structure sites, original and final. Random survey points that can be used to generate a Digital Terrain Model (DTM) if they are of adequate spacing and detail so that cross sections that meet the requirements of this paragraph can be obtained from the DTM. The DTM shall be compatible with the Four Corners Construction Office's present software.


(6) Perform as built surveys as required for all phases of the work.


e. Records.   All survey data shall be recorded in accordance with standard methods approved by the COR. All original field notes, computations, and other records for the purpose of layout and quantity surveys shall be recorded in Government furnished field books. The Contractor, immediately upon completing and reducing the notes for a survey or portion of survey, shall furnish a copy to the Government. A copy of the notes for each workday shall be furnished to the Government at the conclusion of each workday. Upon completing a field survey book, the original field survey book shall be submitted to the Government. Notes not in accordance with acceptable formats will be rejected. Illegible notes or erasures on any pages of notes in any field book will be considered sufficient cause for rejection by the COR of a part or all of the field book containing the illegible notes or erasures. Copied notes will not be accepted; therefore, rejection of a field notebook may necessitate resurveys of the rejected portions. Corrections made by ruling or lining out errors will be acceptable. If prior approval is given by the COR, notes may be collected on an electronic data collection device. The notes shall be transferred to the COR in a previously approved format. If the Contractor submits their data by an approved electronic format, hard copies of the data will not be required unless otherwise directed by the COR.


f. Degree of accuracy.   The degree of accuracy shall be of an order high enough to satisfy the desired tolerances for various types of work. Accuracy of other survey work shall be within the following tolerances:


Points for cross sections shall be located to the nearest 0.1 foot horizontally and vertically.


Vertical elevation surveys shall close within 0.05 foot times the square root of the length of the circuit in miles.


All grade stakes (blue tops) shall be set to 0.01 foot.


Alignment of tangents and curves shall be within 0.1 foot.


Points for structures shall be set to the nearest 0.01 foot, except where operational function of special features or installation of metalwork and equipment require closer tolerances.


g. Equipment and materials.   The Contractor shall furnish all equipment and materials, including instruments, stakes, spikes, steel pins, templates, platforms, tools, and other accessories as may be required in laying out any part of the work from the primary control points established by the Government, and in performing quantity surveys. Instruments shall be accurate and shall be subject to rigid inspection, and any defective instrument, as determined by the COR, shall be promptly replaced, repaired, or adjusted as directed.


h. Cost.   The cost of all materials furnished by the Contractor and all work performed by the Contractor for layout of work, quantity surveys, and related work as herein required shall be included in the prices bid in the schedule for the items of work which require surveys.


1.1.5 SUBMITTAL REQUIREMENTS


a. General.   The Contractor shall furnish all materials and perform all work required for furnishing submittals to the Government, in accordance with the clauses entitled "Technical Data Submittal Requirements," "Specifications and Drawings for Construction" and "Administration of Specifications and Drawings for Construction," this paragraph, Table 1A, and the requirements in the provisions, clauses, and paragraphs of this solicitation.
