CONSTRUCTION STAKING 02001-5

C. Method of survey for new survey control points:

1. New control points will be set by traversing through the new points and two (2) existing control points and measuring the closing angle at the second existing point.

If ratio of closure meets the precision and accuracy standards defined in paragraph 3.3 above, the coordinates of the new points will be adjusted by any standard traverse adjustment method.

2. Where single control points are added between two (2) existing points, the new point may set as in C.1, or by locating the new point from two (2) existing points. If the error circle for the two different coordinate positions meets the precision and accuracy standards defined in paragraph 3.3 above, the coordinates of the new point will be the mean of the two observed positions.

3. Conventional differential levels or three-dimensional traverse (“trig. levels”) may be used to determine elevations as long as closures meet the precision and accuracy standards defined in paragraph 3.3 above.

Differences in elevations exceeding 1/2 foot at any two or more consecutive points shall be reported to the Contracting Officer for evaluation and possible revision. Staking of these areas shall be deferred until the Contracting Officer resolves these differences.

3.6 CLEARING LIMIT, SLOPE, AND REFERENCE STAKES

A. Clearing limits shall be staked when requested by the Contracting Officer.

1. The clearing limits shall be located on the ground to the dimensions AS SHOWN ON THE DRAWINGS or specified by the Contracting Officer.

2. The location shall be within the tolerances specified in paragraph 3.3.

3. The clearing limits shall be marked with lath, flagged, or other methods approved by the Contracting Officer.

4. Method for recording clearing limit data on stakes shall be approved by the

1. Method for recording slope stake information on stakes shall be approved by the

C. The Contractor shall establish slope reference stakes at a minimum horizontal distance of 10 feet beyond the slope catch point (or clearing limits).

1. The elevation and location of slope reference stakes shall be verified for accuracy by differential leveling between slope reference stakes of adjacent points.

a. Where the difference in reference stake elevation between that established by slope staking and that observed by differential leveling exceeds the allowed tolerance, the slope stake shall be reset.

2. Record on the reference stakes the horizontal distance to the nearest coordinate point and the vertical distance to the construction grade.

3. The offset from the slope stake catch point and slope stake catch point information shall be recorded on the reference stake and in the slope stake book.

4. Method for recording slope stake information on reference stakes shall be approved by the Contracting Officer.

3.7 MONUMENTS OF PROPERTY BOUNDARIES OR SURVEYS OF OTHER AGENCIES

A. If property boundary or survey monuments, or survey markers of other agencies, are found within or adjacent to the construction limits, the Contractor shall immediately notify the

1. Existing Monuments shall be protected at all times and tied to the control survey as references.

3.8 STAKING DRAINAGE AND OTHER STRUCTURES

A. Stakes shall be set at all drop inlet and manhole locations. A reference stake and hub shall be set on the centerline 10 feet from each end or beyond the clearing limit, whichever is greater.

The following shall be recorded on these stakes:

1. Diameter, size and type of structure.

2. The vertical and horizontal distance from hubs to the centerline invert.

CONSTRUCTION STAKING 02001-7

B. The Contracting Officer prior to commencement of construction shall review other structures located in conjunction with site staking. Adjustments necessary for any relocation of said structures shall be furnished to the Contractor. This shall be considered a changed condition.

3.9 GRADE FINISHING STAKES

A. Finishing stakes shall be set. Sub grade finishing stakes shall be blue tops. Base course finishing stakes shall be red tops.

B. Stakes shall be nominal 1-inch by 1-inch hubs and shall be of sufficient length to provide a solid set.

C. Finishing stakes shall be placed at all centerline stations established. Stakes shall be set at Centerline and at the edge of finished surface.

D. Finishing stakes shall be set when sub grade is within 0.5 feet, or base course is within 0.2 feet of final grade. The stakes shall be set to the nearest 0.02 feet of the measured grade line.

3.10 STAKE APPROVAL AND MAINTENANCE

A. Construction work shall not begin within an area of the site until the Contracting Officer has approved the stakes, marks, and controls established by the Contractor in writing. The minimum segment for approval shall be 20,000 sq. ft. of the project.

B. Approval of the construction staking will not relieve the Contractor of the responsibility for maintaining the survey work and for correcting errors, whether the errors are discovered during the actual survey work or in subsequent phases of the project. Stakes will be maintained or referenced with the appropriate staking format.
