395 ALASKA 2020 SECTION 642 CONSTRUCTION SURVEYI NG AND MONUMENTS
642-1.01 DESCRIPTION . Perform surveying and staking essential for the completion of the
project and perform the necessary calculations required to accomplis h the work in conformance with the Plans and Specifications and standard engineering and survey practice. Furnish and install survey monuments and monument cases in conformance with the Plans or as directed. Adjust existing monuments and monument cases to conform to the new elevations.
642-1.02 Definitions .
1.Monument : A fixed physical object marking a point on the surface of the earth; used to commence or control a survey; mark the boundaries of a parcel of land; or the centerline of a right-of-way corridor . Monuments will be Primary or Secondary, as shown on the Plans.
2.Point : An identified spot located on the surface of the earth. For purposes of this definition, a point can be a PK nail, wooden hub, rebar, large nail or other structure capable of being utilized as a marker.
3.Witness Corner : A material mark or point usually placed on a property or survey line, at a known distance from a property corner or other survey point. A witness corner is employed to witness the location of a corner/point that cannot be monumented at its true location.
4.Reference Monument : A material mark or point placed at a known distance and direction from a property corner or other survey point, usually not on a property or survey line. A reference monument is employed to perpetuate a corner/point that cannot be monumented at its true location or where the corner monument is subject to destruction.
5.Surveyor : The Contractor’s Professional Land Surveyor, currently registered in the State of Alaska.
642-2.01 Materials.
1.Monument Cases : Use castings meeting AASHTO M 105, Class No. 30A. Coat castings with a bituminous damp- proof coating. Use tops that bear evenly on the frames.
2.Primary Monument : A minimum 2 -inch diameter nonferrous pipe at least 30 inches long, with a minimum 4 -inch flange at the bottom and having magnets attached at the top and bottom. A minimum 2 -3/8 inch diameter nonferrous metal cap must be permanently attached to the top. Mark the cap around the outside edge with the words “STATE OF ALASKA DOT&PF". Permanently stamp every monument with the Surveyor’s registration number, the year set, and the point/corner identification. Orient cap so that the data may be read when the reader is facing north, except for centerline monuments that will be oriented to be read facing up-statio n.
3.Secondary Monument : A minimum 5/8 inch x 30 inches rebar with a 2- inch aluminum cap attached to the top. Permanently stamp every secondary monument with the Surveyor’s registration number, the point/corner identification, and the year set. CONSTRUCTION REQUIREMENTS
642-3.01 GENERAL. Use competent, qualified personnel and suitable equipment for the layout
work required and furnish traffic control, stakes, templates, straight -edges and other devices necessary for establishing, checking and maintaining the required points, lines and grades. 396 ALASKA 2020 Furnish computer services to accomplish the work. Check data received from the computer for completeness and accuracy. As soon as practical after completion of the work, and in no case later than acceptance of the project , deliver field books, computer forms and computer output data to the Engineer. This data becomes the property of the Department. Supervise construction surveying personnel. Correct errors resulting from the operations of said personnel at your expense. The Contractor is responsible for the accuracy of the work. Work classified as Land Surveying under AS 08.48, and work involving the location, control, and monumentation of construction centerline and right -of-way, must be performed by or under the responsi ble charge of a Professional Land Surveyor. Follow the Department’s Construction Surveying Requirements . The Department will provide sufficient centerline or reference thereto, and at least 2 benchmarks per mile to enable the establishment of planned eleva tions and centerline. Keep field notes in standard hardbound notebooks in a clear, orderly, and neat manner consistent with Departmental procedures, including titles, numbering, and indexing. Make field books available for inspection by the Engineer’s proj ect personnel at any time. Store the field books in the Engineer’s Project Office during periods of non- use. Perform the following:
1.Staking necessary to delineate clearing and/or grubbing limits.
2.Cross sections necessary for determination of excavation and embankment quantities, including intermediate and/or remeasure cross sections as needed. Take cross sections after clearing and grubbing has been completed.
3.Slope staking.
4.Staking of signs, culverts, minor drainage structures and other appurtenances, incl uding the necessary checking to establish the proper location and grade to best fit the conditions on site.
5.Bridge staking.
6.Setting finishing stakes.
7.Measurement of pay quantities that require measurement.
8.Staking of right -of-way and material source limits .
9.Staking, referencing and other actions required to preserve or restore land monuments and property corners.
10.Other surveying and staking necessary to complete the project. When the project centerline points have been established as a part of the Department’s Preconstruction surveys, the Department will furnish the Contractor with copies of the reference field books or control sheets depicting reference point information. Recover these control points and independently verify these references. Reestablish mi ssing points from the Department’s references before clearing, grubbing, or excavation. When the Department has not established the project centerline points but the survey control points were established as a part of the Department’s Preconstruction surv eys (as detailed on the project Survey Control Sheet) recover these points and use them as the basis for establishing the 397 ALASKA 2020 project centerline. Verify the position of these points and establish new points where required to replace missing points, before clearing, grubbing, or excavation. Notify the Engineer immediately if a Department -established reference point is discovered to be in error or a reset point is not in harmonious relationship to the adjacent centerline points. Furnish a notekeeper to record field survey notes, including documentation for quantity computations for payment. Ensure that the notekeeper is thoroughly familiar with generally accepted standards of good survey notekeeping practice and the Department’s Construction Surveying Requirement s. The Engineer may randomly spot check surveying, staking and computations. After the survey or staking has been completed, provide the Engineer with a minimum of 72 hours notice before performing work, and furnish the appropriate data, to allow for random spot checking. The Department assumes no responsibility for the accuracy of the work.
642-3.02 CROSS -SECTI ON SURVEYS. When required, obtain right -angle cross sections to the
construction centerline at the interval detailed in the Department’s Constructi on Surveying Requirements . The Department will supply following:
1.Construction Plans and Specifications
2.Design Cross Sections, if any
3.State of Alaska Land Survey Monument Record forms
4.Department’s Construction Surveying Requirements (one copy)
5.Design centerline grades, unless Item 642.0002.____, Office Engineering is used Perform the following:
6.Furnish hardbound field books (Level, Cross -Section, Slope Stake, etc. ). Use “Rite- in-the- Rain” or similar weather resistant books. Field books become the property of the Department upon completion of the work.
7.Label the books and number the pages. Make a heading in the appropriate book (date, weather, names and duties of crew members) at the beginning of each day's work.
8.Update the index of the appropriate book at the end of each day's work.
9.Reduce, check, and adjust level notes.
10.The notekeeper shall compute the cross -section level notes and slope stake catches and a different crew member shall check the computation on a continual basis in the field.
11.Enter the grade data, shoulder width and/or ditch distance, stationing, slope, etc., in the slope stake books.
12.Maintain the position and identifying marks of slope stakes and reference points until used for their intended purpose.
13.Correct errors by drawing a line through them and writing the correct entry directly above. Erasures are not allowed. 398 ALASKA 2020 14. Return field books or copies of the field books to the Project office at the end of each work day or as directed.
15.Provide copies of grade sheets and temporary bench mark elevati ons to the Engineer 48 hours before beginning work on unclassified excavation or embankment.
16.Ensure that survey crews comply with approved traffic control plans. Coordinate crews activities with the Worksite Traffic Supervisor.
17.Keep a daily survey Party Chief diary, and give a copy of the diary to the Engineer each day. The diary shall contain the following information:
a.Date
b.Weather
c.Crew members’ names and duties
d.Type and location of work performed
e.Hours worked
f.Type of equipment used (brand) and date equipm ent was double centered or “peg” test was performed
g.Signature of person in responsible charge
18.Submit the survey field notes for the specific area, relating to monument referencing, before beginning clearing, grubbing, or excavation.
642-3.03 MONUMENTS. Install primary and secondary monuments, as called for in the Plans, at
the positions determined by the Department. Reference property markers/corners, monuments, or accessories that may be disturbed or buried during construction. Prepare and record Monument Record Forms in the appropriate Recorder’s Office before disturbing monuments. Monument Record Forms may be obtained from the Engineer. Reestablish monuments in their original position before completion of the project. Prepare and file a Monument Record F orm for each reestablished monument. Keep records and report to the Engineer evidence that a monument has been disturbed and is no longer reliable or cannot be located and is presumed to be lost or obliterated. Establish a minimum of two in- line reference points, or three swing- tie reference points in situations where in- line referencing is not desirable. Set reference points outside of the construction limits. Measure distances from the monument to the nearest 0.01 foot. Record referencing of monuments i n a separate field book stamped by the Surveyor. Replace existing monuments disturbed by construction with Primary or Secondary Monuments meeting the requirements of subsection 642- 2.01. When it is impractical to establish a monument in its original position, install a witness corner (WC). Place the WC to a property corner on the property line when the other property corner that defines said line is existing or there has been sufficient retracement to define said line. In other cases, place a reference monu ment (RM) perpendicular to the centerline at the station of the original position and at a distance from the original position measured in whole feet. Replacing monuments not shown on the Plans will be considered additional work and paid by 642.0003.____, Three Person Survey Party. Those monuments found that are not shown on the Plans will be recognized by the Department when the Surveyor provides timely field notes identifying type and location of the monument, and a description of the point the monument marks, with the reason to preserve its location. 399 ALASKA 2020 The Surveyor must complete and stamp a State of Alaska Land Survey Monument Record form for each primary and secondary monument removed, installed, relocated, or replaced. Provide the required survey information on the form in accordance with statutory requirements, including section, township, and range. Meet requirements for recording at the District Recorder’s Office in which the project is located for each monument record. Deliver conforming copies of the recorded forms to the Engineer before monument removal or disturbance and after setting any final monuments requiring monument records. Set each monument and monument case accurately to lines established at the required location and in a manner as to ens ure being held firmly in place. Set existing monuments and monument cases to be adjusted to new elevations in the manner and at the elevations directed.
642-3.04 OFFICE ENGI NEERING. Calculate finish grades for the roadway as specified according
to Plans and/or Specifications. Use information available in the field, on as -builts, or as provided by the Engineer. Perform the work by, or under the responsible charge of, a person registered in the State of Alaska as a Professional Land Surveyor or a Professional Engineer.
642-3.05 FINAL TRAVE RSE. Within 30 days after the Engineer receives a letter stating that
construction activities that may disturb the monuments have ceased, the Surveyor shall run a final closed traverse to verify the positional accuracy of ins talled survey monuments. Begin and end this traverse at different Department -provided control points. Tie into the traverse the primary and secondary monuments placed or replaced and undisturbed Department -provided control points. Do not run the final trav erse more than 2.5 miles without a tie to a Department -provided monument/control point. Meet the requirements of a secondary monument for traverse points established during this work. Have the Surveyor sign and stamp a letter that lists each monument and i ts coordinates and certify that the monuments are each located within 0.2 feet of their proposed position based on the project survey control points provided by the Department. Deliver the certification letter and field notes for this work to the Engineer.
