934.01 DESCRIPTION. This work consists of establishing, on the ground, all required Field Control
and Construction Layout. Project Field Control and Lay out is defined as accurately providing all necessary computations, stakes and marks required to establish lines, slopes, elevations, points, and continuous profile grades in order to perform a ll the required work for the project in accordance with the Contract requirements. Field Control and Layout is required to enable the Engineer to complete all necessary inspection, checks, verification of quantities and Contract Administration duties. The staking shall include, but not be limited to, clearing and grubbing, grading, drainage, culverts, embankments, borrow, aggregate base c ourse, pavements, bridges, utilities, signs, pavement markings, erosion control, and turf establishment items to complete the project as represented in the plans. The Surveying must be done in a way that is timely, and that is reflective of the continuing and ongoing nature of construction and inspection activities which will generally require frequent, separate project visits by the C ontractor’s survey crew, to the project to accommodate the various stages of construction and inspection activities that will occur. Field Control shall also include all survey required to accurately generate standard cross sections, measure quantities, layout for utility companies, and generate as-built drawings.
934.02 MATERIALS. All survey wedges and survey stakes shall be of seasoned oak and free of
knots. Survey wedges used for control staking shall be 1-¾” x 1-¾” and 18-inches in length. For slope limits, pavement edges, gutter lines, etc., the use of survey stakes shall be acceptable and shall be 1” x 1” and 4’-0” in length.
934.03 Construction Layout
934.03.1 General Responsibilities. It is the responsibility of the Contractor to establish field control
and to lay out the work which is proposed within the Contract. The Engineer will furnish the Contractor with basic field control and survey data for all projects except for resurfacing projects, as basic field control is not necessary to perform the work on these projects.
934.03.02 Department's Responsibility. The Engineer will furnish the Contractor with basic field
control and survey data for all projects, except re surfacing projects, upon Contract Award. This shall include confirming and re-establishing c ontrol, in the field. The basic field control will include control points, benchmarks, survey data files, survey plan sheets, and other data, which may be required for the Contractor to perform construction staking, layout, and maintenance of the basic field control. Survey work may be monitored by the E ngineer for conformance to standard survey practices. The Engineer shall be notified, by t he Contractor, 24 hours prior to any survey work being performed in the field. The Engineer/Surveyor may check the control of the work, as established by the Contractor, at any time as the work progresses. 9−74 At the discretion of the Engineer, spot checks may be performed upon the Contractor’s surveying calculations, records, field procedures, or actual staking. If the Engineer determines that the work is not being performed in a manner that will assure proper controls and accuracy, the Engineer will direct the Contractor to redo such work to the standards specified in the contract at no additional cost to the State. Also, should the Department sustain costs checking and/or correcting Contractor survey and resultant product caused by Contractor survey errors and/or omissions, the Engineer will deduct those related actual costs incurred by the Departm ent from any payments owed the Contractor.
934.03.3 Contractor's Responsibilities. The Contractor shall be responsible, at a minimum, for
the following:
a.Pre-Construction Surveys shall be submitted to the Department five (5) working days prior to the commencement of any clearing and grubbing, or earthwork. These surveys shall accurately record the existing conditions of areas where work is proposed. Pre-Construction Surveys shall be submitted to the Engineer elec tronically in both CADD and survey data files. Pre-construction surveys shall accurately record the existing conditions, as identified in the Contract Documents, and areas where work (disturbance) is proposed. This shall include original grades; curb line and grades, sanitary and drainage stru ctures and inverts; eas ements; visible utility locations; etc. The Contractor shall notify the Engineer, in writing, of any discrepancies between the Design Plans and their pre-construction survey. The Contractor shall not disturb the areas in question, until the Engineer responds to the Contractor’s notification. The Engineer will respond to Contractor within five (5) working days. Furthermore, should the Contractor fail to comply with these requirements, all time, rework and delay costs associated with survey inaccuracies shall be borne solely by the Contractor; no additional payment will be allowed.
b.Construction stakes shall be set for all project construction, and shall be installed as reference points, as needed, for the use of any public utility crews that are staking or accomplishing utility relocations, or construction associated with th is contract. References to staking, additional or replacement thereof, which may be required for the construction operations shall be furnished, set and properly referenced by the Contractor. Cons truction stakes shall be clearly labeled by referencing station, offset, and purpose. The intent of the labeling is so both the Contractor and Engineer may accurately interpret the field control. In particular, the Department’s personnel need to be able to orientate themselves in the field based on the staking to confirm construction operations are in conformance with design plans and specifications.
c.Re-staking shall be performed, as needed, due to progressive change in operation including, but not limited to:
1.Identification of Limits 2. Staking for Excavation 3. Staking for Grading 4. Staking for new Drainage and Utilities including center of proposed structures and elevation.
5.Staking for curbing and final pavement 9−756. Staking of easements
d.Structures and Bridges construction staking which includes setting and reestablishing Working Points and Reference Points by XYZ coordinates to provide line and grade during all stages of work, and at all substructures and segments of Bridge or Structure Construction, as shown below:
1.Establish Working Points or Reference Points, approved by the Engineer, on the ground as shown on the Bridge Layout sheet in the Plans.
2.Transfer of 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, the Contractor’s Surveyor sha ll mark a curved line on the footings, forms, or deck slab, to the proper degree of curvature within 1/8" in ten (10) feet, as needed for construction and inspection activities.
3.Transfer required points to the top of all finished structures. 4. Transfer required points to the superstructure deck forming. 5. Measurements and marks for plumbness are also required.
e.Establish and Protect adequate ties to all control points such that they can be conveniently re-established if disturbed or destroyed. This includes the preservation of all reference points, monuments, horizontal and vertical control points, stakes, and marks that are established by the Department or their representatives, within the project limits. If the Contractor or its surveyor fails to preserve these items and if they must be reestablished it will be the responsibility of the Contractor to do so at no additional cost to the State.
f.A Rhode Island Registered Land Surveyor (RLS) shall be retained by the Contractor to be responsible for all survey work; which shall be performed in accordance with the Department’s procedures and the procedures established by the “Procedural and Technical Standards for the Practice of Land Surveying in the State of Rhode Island and Providence Plantations” prepared by the Rhode Island Society of Professional Land Surveyors and adopted by the Rhode Island Board of Registration for Professional Land Surveyors. The Contractor shall submit to the Engineer for approval the RLS who will be responsible for t he survey work on the project. The Engineer will review the qualifications of the RLS and respond, in writing, to the Contractor within five days as to the acceptance of the candidate. The Contractor must notify the Engineer prior to any changes to the RLS in charge. While all work must be overseen by an RLS, the survey Party Chief shall also be an RLS. Any surveying or measurements necessary fo r the computing of pay quantities shall be performed by the Contractor’s RLS in the field. The Contractor shall notify the Engineer at least five (5) working days prior to disturbing any areas where survey will be used to calculate pay quantities. Additionally, the Contractor shall afford the Department five (5) working days for verification, upon receipt, of cross sections stamped by the RL S. Where the Department deems it necessary and appropriate to check the Contractor’s quantity-relat ed field survey data, the Contractor shall not perform any operations during the five (5) day peri od that may render Department’s efforts to check the Contractor’s survey ineffective. The final monumentation of the project must be supervised by the Contractor’s RLS. 9−76 g. Field Records shall be maintained by the Contractor in Department approved field books. Copies of field book pages, survey documentation and calculations shall be submitted to the Engineer, in a form acceptable to the Department, on a daily basis. Upon completion of the construction work, original field books and records shall be submitted to the Department. The copies shall be submitted in both hard copy and electronic files (Adobe PDF format, latest edition on approved DVD media). The survey documentation shall include: 1. Control station monumentation with reference ties. 2. Field notes that were used to set construction stakes, control the Project, and document monument locations. The Contractor shall use bound, hard cover field books for recording survey data and field notes, and/or store field notes on an electronic medium. If an electronic medium is used, the raw field data files must be made available, and the Contractor shall make all files and data available in the Standard formats used by the Department.
h.As-Built surveys shall be performed and drawings submitted to the Engineer to document all changes to the proposed Contract work. The Contractor shall provide the Engineer with the as-built data in both hard copy reproducible material and electronic files. This data shall be provided to the Engineer as changes/additions occu r. The Engineer may request verification of any and all survey data. The Contractor shall be responsible for submitting this data within five (5) working days of the request. The as-built data shall include the following:
1.Construction changes/additions in alignment, profiles, typical sections, structures, drainage, tapers, roadway widths, utilities, and curb types pertaining to location and elevation, on the copy of the appropriate construction Plans.
2.Revised coordinates for any of the above items. 3. Revisions in centerline station and offset. 4. Pile cut-off elevations. 5. Bearing elevations.
i.Miscellaneous.
1.The Engineer’s acceptance of all or any part of the Contractor’s layouts shall not relieve the Contractor of responsibility to secure proper dimensions for the completed work.
2.The Contractor shall bear all costs, including but not limited to the cost of actual reconstruction of contract work, that may be incurred due to errors in the Contractor’s field control and construction layout.
3.No claims for extensions of time or additional costs associated with delays as the result of this work will be allowed. 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 in order to stake these components. 9−77 All level runs, traverses, or GPS control su rveys, shall start and end from known control. Complete all control surveys in accordance with “Procedural and Technical Standards for the Practice of Land Surveying in the State of Rhode Island and Providence Plantations”.
934.04 METHOD OF MEASUREMENT. The field control and construction layout work is deemed
incidental to the contract and will not be measur ed for payment. The incident al survey and survey- related work shall include, but not be limited to, all on-site field work as well as on-site and off-site office work such as calculations, sketches, drawings, tabulations, correspondence, research and any other tasks required to complete the work to the satisfaction of the Engineer. Re-work, including re-staking, performed for any and all reasons, is deemed incidental and will not be measured for payment.
a.Measurement for Extra Work. Survey work performed outside the scope of the original contract at the direction of the Engineer will be deemed Extra Work, and will be documented and paid for on a Force Account basis as set forth in Subsection 934.05.
