152 - Construction Survey and Staking
Delete Section 152 in its entirety and replace with the following.
Description
152.01 This work consists of furnishing qualified personnel and necessary equipment and material to survey, stake, calculate, and record data for the control of work. See FAR Clause 52.236-17 Layout of Work.
Personnel, equipment, and material shall conform to the following:
(a) Personnel. Furnish technically qualified survey crews experienced in highway construction survey and staking. Provide personnel capable of performing in a timely and accurate manner. An acceptable crew supervisor shall be on the project whenever surveying/staking is in progress.
Conduct construction staking under the direct supervision of a professional engineer registered for the state in which work is completed.
(b) Equipment. Furnish survey instruments and supporting equipment capable of achieving the specified tolerances.
(c) Material. Furnish acceptable tools, supplies, and stakes of the type and quality normally used in highway survey work and suitable for the intended use. Furnish stakes and hubs of sufficient length to provide a solid set in the ground with sufficient surface area above ground for necessary legible markings.
Use required stake dimensions and materials. Pre-paint the top 2 inches of all stakes and lath, or mark them with plastic flagging. Use designated colors for paint or flagging. Mark all stakes with a stake pencil that leaves a legible imprint, or with waterproof ink.
Do not use aerosol spray paints in the field. Provide for the safe storage use and clean-up of paint when on National Forest System Lands. Immediately report all spills to the CO, clean-up and disposal of spills and painting waste shall be in accordance with Federal state and local requirements.
Use moisture-resistant paper for survey notes. Keep notes in books with covers that will protect the contents and retain the pages in numerical sequence. At the conclusion of each road segment, the registered engineer shall affix the state authorized seal and sign all field books and drawings and attest in writing to the satisfactory completion of the project.
152.02 General. When indicated on the plans, a preliminary survey line has been established on the ground. The project location line is established by offsets from this preliminary line. Data relating to horizontal and vertical alignment, theoretical slope stake catch points, and other design data will be furnished.
Before beginning construction, notify the CO of any missing initial reference lines, control points, or stakes. Reestablish missing reference, control lines, or stakes as necessary to control subsequent construction staking operations
Appendix D, Page 15 of 64
Perform additional calculations for convenient use of Government-furnished data. Provide immediate notification of apparent errors in the initial staking or in the furnished data.
Preserve all initial reference and control points. After beginning construction, replace all destroyed or disturbed initial reference or control points necessary to the work.
Before surveying or staking, discuss and coordinate the following with the CO:
(a) Surveying and staking methods;
(b) Stake marking;
(c) Grade control for courses of material;
(d) Referencing;
(e) Structure control; and
(f) Any other procedures and controls necessary for the work.
Survey and establish controls within the tolerances shown in Table 152-1.
Prepare field notes in an approved format. Furnish all survey notes at least weekly. All field notes and supporting documentation become the property of the Government upon completion of the work.
Start work only after staking for the affected work is accepted.
The construction survey and staking work may be spot-checked for accuracy, and unacceptable portions of work may be rejected. Resurvey rejected work, and correct work that is not within the tolerances specified in Table 152-1. Acceptance of the construction staking does not relieve the Contractor of responsibility for correcting errors discovered during the work and for bearing all additional costs associated with the error.
Remove and dispose of all flagging, lath, stakes, and other staking material after the project is complete.
152.03 Survey and Staking Requirements. Perform all survey, staking, recording of data, and calculations as necessary to construct the project from the initial layout to final completion.
Reset stakes as many times as necessary to construct the work.
(a) Control points. Relocate initial horizontal and vertical control points in conflict with construction to areas that will not be disturbed by construction operations. Furnish the coordinates and elevations for the relocated points before the initial points are disturbed.
(b) Roadway cross-sections. Take roadway cross-sections normal to centerline. When the centerline curve radius is less than or equal to 200 feet, take cross-sections at a maximum centerline spacing of 25 feet. When the centerline curve radius is greater than 200 feet, take cross-sections at a maximum centerline spacing of 80 feet. When the centerline curve radius is greater than 500 feet, take cross-sections at a maximum centerline spacing of 50 feet. Take additional cross-sections at significant breaks in topography and at changes in the typical section. Along each cross-section, measure and record points at breaks in topography, but no further apart than 20 feet. Measure and record points to at least the anticipated slope stake
Appendix D, Page 16 of 64 and reference locations. Reduce all cross-section distances to horizontal distances from centerline.
(c) Slope Stakes and References. Locate slope stakes on designated portions of the road.
Locate the slope stake catch points and use them to establish clearing limits and slope stake references.
Mark slope stakes with the station, the amount of cut or fill, the horizontal distance to centerline, and the slope ratios.
Place slope reference stakes at least 10 feet outside the clearing limit and mark with the offset distance to the slope stake.
Prior to clearing and grubbing operations, move the slope stake outside the clearing limit to the slope reference stake. After clearing and grubbing and before excavation, reset the slope stakes in their original position.
Use the designated method to establish the slope stake catchpoint.
• Method I—Computed Method. Use the template information shown in the plans or other Government-provided data to calculate the actual location of the catchpoint.
The slope stake “catchpoint distance” provided may be used as a trial location to initiate slope staking. Recatch slope stakes on any section that does not match the staking report within the tolerances established in Table 152-2.
• Method II—Catchpoint Measurement Method. Determine the location of slope stake catchpoints by measuring the catchpoint distances shown in the plans or other Government-provided data.
(d) Clearing and grubbing limits. Set clearing and grubbing limits on both sides of centerline at roadway cross-section locations.
Establish clearing limits on each side of the location line by measuring the required horizontal or slope distances shown in the stake notes. Mark the clearing limits with flagging or tags on trees to be left standing, or on lath. Make markings intervisible, and no more than 90 feet apart.
After establishing clearing limits, move the location line stake outside the clearing limits for station identification purposes, and mark it with horizontal distance to location line
(e) Centerline reestablishment. Reestablish centerline from instrument control points. The maximum spacing between centerline points is 25 feet when the centerline curve radius is less than or equal to 200 feet. When the centerline curve radius is greater than 200 feet, the maximum distance between centerline points is 80 feet.
(f) Grade finishing stakes. Set grade finishing stakes, for grade elevations and horizontal alignment, on centerline and on each shoulder at roadway cross-section locations. Set stakes at the top of subgrade and the top of each aggregate course.
Where turnouts are constructed, set stakes on centerline, on each normal shoulder, and on the shoulder of the turnout. In parking areas, set hubs at the center and along the edges of the parking area. Set stakes in all ditches to be paved.
Appendix D, Page 17 of 64
When the centerline curve radius is less than or equal to 200 feet, the maximum centerline spacing for stakes is 25 feet. When the centerline curve radius is greater than 200 feet the maximum centerline spacing for stakes is 80 feet. The maximum transverse spacing between stakes is 20 feet. Use brushes or guard stakes at each stake.
(g) Culverts. Stake culverts to fit field conditions, the final locations may differ from the plans. Set a culvert reference stake on the centerline of the culvert 10 feet from each end or beyond the clearing limit, whichever is greater. Record the following on culvert reference stakes:
(1) Diameter, actual field measured length, and type of culvert.
(2) The vertical and horizontal distance from the reference stake to the invert at the ends of the culvert.
(3) Station of actual point where culvert intersects centerline.
Stake headwall for culverts by setting a hub with a guard stake on each side of the culvert on line with the face of the headwall. Perform this work after clearing is completed.
(h) Bridges. Set adequate horizontal and vertical control and reference points for all bridge substructure and superstructure components. Establish and reference the bridge chord or the bridge tangent. Also establish and reference the centerline of each pier, bent, and abutment.
(i) Retaining walls. Survey and record profile measurements along the face of the proposed wall and 5 feet in front of the wall face. Every 25 feet along the length of the wall and at all major breaks in terrain take cross-sections within the limits designated by the CO. For each cross-section, measure and record points every 25 feet and at all major breaks in terrain. Set adequate references and horizontal and vertical control points.
(j) Borrow and waste sites. Perform the work essential for initial layout and measurement of the borrow or waste site. Establish a referenced baseline, site limits, and clearing limits.
Survey and record initial and final cross-sections.
(k) Permanent monuments and markers. Perform all survey and staking necessary to establish permanent monuments and markers. Set permanent monuments according to Section 621.
(l) Miscellaneous survey and staking. Perform all surveying, staking, and recording of data essential for establishing the layout and control of the following, as applicable:
(1) Approach roads and trails;
(2) Curb and gutter;
(3) Guardrail;
(4) Parking areas;
(5) Paved waterways;

(m) Field Discrepancies. Immediately notify the CO if a discrepancy is encountered between the plans and field conditions which affect the final road location. Prepare recommendations, in writing, to the CO for adjustments to the design to better fit field conditions. Affix the state authorized seal and sign the recommendation attesting to the adequacy of the adjustment. Ensure that adjustments to the design follow all applicable regulations and are consistent with design standards and criteria. Adjustments shall minimize construction effort, such as clearing and embankment volumes. Gain written approval of the adjusted design from the CO before incorporating such adjustment in the field. Return to the original design as soon as practical.
