SECTION 934 — FIELD CONTROL AND CONSTRUCTION LAYOUT — FIELD CONTROL AND CONSTRUCTION LAYOUT
934.01 Description.
This work includes verifying existing survey control points provided in the Contract documents and establishing additional survey field control, computations, construction layout, worksheets, plans, as-builts, and certifications to fulfill Contract requirements. Complete all work according to RIDOT policy requirements and State Procedural and Technical Standards for the practice of Professional Land Surveying in the State of Rhode Island. Perform t he surveying in a timely manner and to reflect the ongoing nature of construction and inspection activities. This work will generally require frequent, separate site visits by the Contractor’s survey crew to the Project site to accommodate the various stages of construction and inspection activities that will occur.
934.02 Construction Layout.
Department’s Responsibility. The Engineer will provide the necessary horizontal and vertical control points distributed throughout the Project to support development of a field survey control network and subsequent construction layout for the design. The control points provided will be shown on a plan or report certified to the appropriate measurement specification by the designer ’s Professional Land Surveyor and deemed adequate for the construction layout. Contractor’s Responsibilities. The Contractor shall be responsible, at a minimum, for the following:
a.Professional Land Surveyor. Retain a Professional Land Surveyor (PLS) registered in the State of Rhode Island to be responsible for all survey work performed on the P roject. Perform all survey work according to the Department’s policies and procedures. Ensure that all survey work conforms to the current “Procedural and Technical Standards for the Practice of Land Surveying in the State of Rhode Island,” at the Rhode Island Department of Business Regulation website, (https://rules.sos.ri.gov/regulations/part/435- 00-00-1). Submit to the Engineer for approval the Company, Professional Land Surveyor , and current Certificate of Authorization (COA) to practice Professional Land Surveying in the State of Rhode Island. The Engineer will review the information and respond in writing to the Contractor within five days on the acceptance of the candidate . Notify the Engineer before any changes to the COA or PLS in responsible charge.
b.Pr e -Construction Surveys . Submit a Pre-Construction Survey to the Department , performed five working days before any significant disturbance of existing conditions at the site . Perform the necessary horizontal and vertical locations, calculations , and adjustments to verify the existing survey control points provided for construction of the Project. V erify significant existing features and elevations identified in the Contract Documents. Provide the data to the Engineer in an AutoCAD drawing file and report with the appropriate survey backup data. Ensure that the backup data includes a point listing and analysis of survey control points being used to construct the Project. The Professional Land Surveyor shall certify the preconstruction survey and shall deem the data appropriate

SECTION 934 — FIELD CONTROL AND CONSTRUCTION LAYOUT 900-95 for the verification of significant features and elevations and the verification of adequate survey control points. Notify the Engineer in writing of any significant discrepancies or concerns between the information provided in the Contract Documents and their preconstruction surveys . Do not disturb the areas in question until the Engineer responds to the notification.
c.Establish and Protect Survey Control. After existing survey control points have been verified, additional control points may be set and maintained as part of the survey control network for construction of the Project. Properly tie off all survey control points so that they can be conveniently re-established if disturbed or destroyed, including all reference points, boundary monuments, horizontal and vertical control monuments, stakes, and marks that have been established by the Department or their representatives . Set adequate survey control off locus to re-establish the survey control network as necessary. If the Contractor or its surveyor fails to preserve these items and if they must be re - established, perform this work at no additional cost to the Department.
d.G eneral Construction Layout . Set the c onstruction stakes or other appropriate monuments for all construction activities. In addition, install stakes as needed for the use of any utility crews that are staking or accomplishing utility relocations or construction associated with the C ontract. Furnish, set, and reference all stakes or replacement s thereof that may be required for construction operations. Clearly label construction stakes, and perform restaking as needed due to the progressive change in operation.
e.S tructures and Bridge Construction Layout . Structures and b ridge staking may include setting and re -establishing working points and reference points by XYZ coordinates provided in the Contract Documents. This information will be used to calculate and provide line and grade during all stages of work and at all substructures and segments of b ridge or structure construction, as shown below: ● Establish working points or reference points, approved by the Engineer, on the ground as shown in the Contract Documents. ● Transfer the required points from the ground to the top of footing after the completion of concrete footing construction. If the structure is a curved wall or bridge edge of slab, curb, coping, median, or railing, mark a curved line on the footings, forms, or deck slab to the proper degree of curvature within ⅛ in. in 10 ft, as needed for construction and inspection activities. ● Transfer the required points to the top of all finished structures. ● Transfer the required points to the superstructure deck forming. ● Measurements and marks for plumbness are also required.
f.Quantity Measurements . Certify a ny surveying or measurements necessary for the computing of pay quantities . Notify the Engineer at least five working days before disturbing any areas where survey will be used to calculate pay quantities . Additionally, provide the Department five working days for verification, upon receipt, of cross sections or other survey data certified and stamped by the PLS. Where the Department deems it

900-96 SECTION 934 — FIELD CONTROL AND CONSTRUCTION LAYOUT necessary and appropriate to check the Contractor’s quantity-related field survey data, do not perform any operations during the five- day period that may render the Department’s efforts to check the Contractor’s survey ineffective.
g.Field Records. Maintain and organize the records of all surveying work in Department approved field books, worksheets, raw data files, coordinate point files, and other formats approved by the Engineer . Submit copies of all survey documents upon request to the Engineer in a form acceptable to the Department on a daily basis to clearly identify survey services performed. Upon completion of the Contract, submit all field books, worksheets, raw data files, AutoCAD drawing files, coordinate point files, or other survey records to the Department. Submit t he copies in both hard copy and approved standard electronic formats used by the Department.
h.M iscellaneous . ● Notify the Engineer 24 hours before any survey work will be performed in the field. Survey work will be monitored by the Engineer for conformance to standard survey practices and procedures. ● The Engineer’s acceptance of all or any part of the Contractor’s survey services shall not relieve the Contractor of responsibility to secure proper documentation and as-built dimensions for the completed work. ● When required, the Engineer will, in writing, direct the Contractor to make the necessary minor surveying and staking adjustments to suit actual field conditions. In addition, some Plan details may be dependent upon actual field conditions at the time of construction. It may be necessary to perform some field survey and/or office computations to stake these components. ● At the discretion of the Engineer, verifications or backup information may be requested from the Contractor for any survey services performed throughout the Contract. If the Engineer determines that the work is not being performed to ensure proper controls and accuracy, the Engineer will direct the Contractor to redo such work to the standards specified in the C ontract at no additional cost to the Department . Also, if the Department sustains costs checking and/or correcting Contractor surveys and the resultant product contains survey errors and/or omissions, the Engineer will deduct the related costs incurred by the Department from any payments owed the Contractor.
934.03 Method of Measurement.
The Professional Land Surveying services, including field control, construction layout, as-built and associated calculations, plans, worksheets, reports, and certifications, are deemed incidental to the Contract and will not be measured for payment.
934.04 Basis of Payment.
The field control and construction layout work will not be paid for separately but will be included in the bid for the items of work to which the layout is incidental.
