The instructions and sample notes represent the best practicable blending of the many existing note formats to fit the needs of the NRCS. Engineering surveys, staking, notekeeping, calcula- tions, and note interpretations are part of the daily activities of many NRCS personnel, as well as contrac- tors, consultants, district employees, and others. It is important, therefore, that these operations are performed with the greatest possible efficiency and in a manner that will result in maximum usefulness of the information obtained. This calls for uniformity in methods and procedures between States and between workstations within States. General Field notebooks and special forms Bound and loose-leaf field notebooks are both satisfac- tory for most NRCS engineering surveys. However, the loose-leaf notebooks should not be used for project or other contract work where the notes might be used as evidence or supporting data in court actions. Loose- leaf notes are not generally acceptable to the courts. The use of special forms is recommended for re- cording engineering notes and design data for such practices as terraces, diversions, waterways, small pond dams, and similar work. It is extremely impor- tant, however, that the method be uniform and forms provide for at least the minimum construction check information shown in the sample notes. Numbering, identifying, indexing, and filing Numbering bound notebooks Bound field notebooks should be numbered consecu- tively for each broad activity. Use one series of num- bers for ordinary on-farm work (including cost-share programs} in each field office. The numbering may run consecutively from year to year or may start with num- ber 1 at the beginning of each year. In the latter case, the year should precede the number such as 2010–1, 2010–2, etc. Design and construction notebooks for project instal- lation will be numbered in a separate series for each structure. Place the name of the project and the name (if there is one) and number of the structure site on each notebook. All notebooks used to record notes during the project planning stage may be numbered in one continuous series for the project area. A separate series of numbers will be used for each group project. Books containing notes of surveys made for other agencies should be numbered and identified as out- lined for group or project type work. In all cases, the identifying name should be lettered with indelible ink or its equivalent. Identifying notebooks Identify all field notebooks, both bound and loose-leaf, so that they can be returned to proper headquarters if lost. Place this identification on the inside on the front cover or on the flyleaf of bound notebooks. For most loose-leaf notebook binders, it will be necessary to paste a white tab to the inside front cover. The following identification should be used: U.S. GOVERNMENT PROPERTY Finder please return to NATURAL RESOURCES CONSERVATION SERVICE (Street or P.O.

Cross sections, slope stakes, and notes are directed left and right as viewed in the direction of increasing stations. Grade rod The notes for construction layout and check surveys illustrate the use of the grade rod. The grade rod is a time saver and has wide application in NRCS work. It eliminates the need for converting rod readings to elevations and facilitates computations since they may be made directly from the field notes. This eliminates copying time, reduces the time for checking, and the chance for errors. The grade rod is obtained by subtracting the planned elevation at each station from the height of instrument (grade rod = H.I. – planned elev.). When the height of instrument is above the planned elevation, the grade rod has a plus value and is so marked in the notes, such as +5.2. If the height of instrument is below planned elevation, the grade rod has a minus value and is so marked, such as –8.3. To find the cut or fill in construction layout surveys, subtract the actual rod reading from the grade rod. If the result has a minus value, a fill is indicated. If the result has a plus value, it indicates a cut. Example A: H.I. = 249.3 Planned elev. = 243.0 Grade rod = 249.3 – 243.0 = +6.3 Foresight = 9.8 +6.3 – 9.8 = –3.5 a fill Example B: H.I. = 127.4 Planned elev. = l32.6 Grade rod = 127.4 – l32.6 = –5.2 Foresight = 4.2 –5.2 – 4.2 = –9.4 a fill Example C: H.I. = l34.6 Planned elev. = 128.4 Grade rod = 134.6 – 128.4 = +6.2 Foresight = 2.9 +6.2 – 2.9 = +3.3 a cut In construction check surveys, the grade rod for each station is computed as explained. The foresight at each station is mentally compared with the grade rod for that station. Thus, the work can be checked rapidly without the necessity of converting rod readings to elevations. Standard note samples for ordinary on- farm work The following sample notes illustrate the format for several types of surveys used for ordinary on-farm activities. The intent of these samples is to illustrate notekeeping methods, format, identification, content, and completeness. In a limited number of instances, the sample notes include design information for the simpler projects. These design data were used only for illustration and do not establish design criteria. Each set of notes is preceded by explanatory state- ments that should be studied carefully.

The design survey and the construction layout survey were combined in one operation. A reference hub was set at spillway elevation, and the following information was given to the landowner for use by him and the contractor: 1. Total fill height (design height plus allowance for settlement) at each station as measured from the reference hub. 2. Spillway dimensions and its elevation in relation to the reference hub. 3. Top width of fill. 4. Side slopes of fill. 5. Standard specifications for site preparation and placement of fill. Soil investigations and fill volume computations were made and recorded in accordance with State NRCS procedures. Clear River Rayville W.F. Jones Pond 42-010-718 3 mi.

It was determined by taking a few random shots that a ditch with bot- tom elevation at outlet end 1 foot above bottom of the main ditch and having a 0.05 percent bottom grade would give the desired drainage. With this information, the planned bottom elevation and grade rod at each station were calculated. Spoil is to be spread uniformly along each side of ditch during construction. For that reason, reference hubs showing cut from top of hub were offset 50 feet, so they would not be disturbed during construction. The topography was reasonably uniform; therefore, slope stakes were set at 200-foot intervals. Line stakes were set on the centerline at 100-foot inter- vals. SCD Date Field Oce Name Job Design Sur.

A small trickle of water along the ditch bottom indicated uniform grade except at one or two points. These facts were taken into consid- eration in deciding how intensively the work should be checked. Design data from the plan such as bottom width, side slopes, and the planned bottom elevation at each station were listed on a sheet of paper so it would be convenient for reference.

The design was prepared from a survey and soils investigations made during development of an overall plan for the district. The construction check notes illustrate a simple method of checking from the reference hubs. It is simpler and faster than carrying elevations from bench marks, and it is satisfactory for most jobs if reference hubs are offset a safe distance where they will not be disturbed during construction. In using this method, the person who is to do the checking must be given the following information: 1. Planned cut from top of reference hub to bottom of trench at each station. 2. Outside diameter of each size pipe used in the line. SCD Date Field Oce Name Job Design Sur. Const. Check Indent. No. Location Const. Layout Other Field No. Individual Group Unit of Govt.

Every situation is not covered. The samples show format and procedure in sufficient detail for the field engineer or survey party chief to apply them to the particular job. Construction staking must be consistent with contract provisions, and some of the samples may represent portions that are the responsibility of the contractor. Unless otherwise specified, basic staking for embank- ments and excavations includes centerline, slope (toe of slope or edge of cut), and offset reference stakes with hubs at each station and more frequently on curves along the axis of the embankment or excava- tion. Stakes at significant breaks in topography or changes in section of the planned work are also in- cluded. Basic staking for structures includes alignment and grade along the principal axis and may include offset stakes for linear structures, such as a principal spillway through a dam. Computations are closely related to notekeeping. These samples can be used to compute quantities di- rectly from the field notes. Placing the cut or fill above the distance from centerline or reference point facili- tates direct computations. A sample plotted dam cross section and computation are shown. Samples D–15 through D–18 show components of a typical floodwater retarding structure. These exhibits are referred to in the presentation of the sample field notes for layout and also for calculations. Although these figures and the field notes presented are for an earth dam, the content, procedures, and completeness of notekeeping are directly applicable to other major construction work. Elevations for earthwork are usually computed to the nearest one-tenth (0.1) foot. Where grades or control elevations are not shown on the drawings, sufficient information for rough grading may be established by scaled measurements taken from the drawings. A standard practice is to set grades for the various elements of structures to the nearest hundredth (0.01) of a foot. All construction stakes should be set and marked to show finish elevation. Additional information may be added to stakes and notes for subgrades or other specific construction datums as needed. Engineering notes—Construction stakeout Sample D–24 illustrates a format for stakeout notes for dams or other embankments. The elevations and structure dimensions illustrated are from plan data in samples D–l5 through D–18 and field notebook sample D–20. The example shows the original cross section and embankment staking. The foundation was stripped and a second cross section was taken concurrently with setting the cutoff trench cut stakes. This is an optional procedure and, in some cases, one cross section will be sufficient. The (T) denotes the edge (toe) of fill or cut. Sample D–24 illustrates a format that may be used for recording the layout notes for the construction of principal spillways for flood control dams and can also be readily adapted for use in laying out other types of closed conduits or culverts. Sample D–25 illustrates a format that may be used for recording notes for the cross sections and the layout of the auxiliary spillway or other earthwork. The work may consist of excavation or sections that combine excavation and embankment. The layout, including curve data, and the elevations for this example were taken from sample D–22. Simple curves are frequently required in the layout of embank- ments, excavations, or elements of structures. Sample D–35 shows how a correction for curvature is made for an excavation between two asymmetrical sections located in the curve of an auxiliary spillway. Stationing for the project should be continued along the centerline of the curve at the time of stakeout, and these stations should be used as control points for cross sections and the staking of the structure limits. Transverse measurements are made normal to the tangent to the curve at the point under consideration. This measurement line parallels an imaginary line that passes through the centerline station and the refer- ence or radius point for the curve. Plotting and considerations Sample D–26 shows the plotted cross section of dam centerline station 15+10. Fill height and distance from the centerline are the parameters used for plotting. D–75(210–VI–NEH, Amend. 51, March 2012) Part 645 National Engineering Handbook Appendix D Sample Engineering Notes and Computations Calculations should normally be made directly from field notes. It may be necessary in cases of complex geometry to plot cross sections to visualize the ele- ment. However, copying numbers and plotting cross sections should be kept to the minimum. They may be used were appropriate. Sample D–27 shows a con- venient way of tabulating field notes for calculations where it is not convenient to compute directly from the field notebook. Setting and marking stakes Sample D–28 shows an example for staking embank- ments. This is the same cross section as recorded on sample D–23 shows an example for staking an open channel spillway. This is the same cross section as recorded for auxiliary spillway station 9+12 on sample D–25. The berm was added to the sketch to show the procedure (not in notes.) Stake location and markings must convey the necessary information. The examples show proven methods but may be varied to accom- plish this objective. Sample D–30 shows stake marking for various pur- poses applicable to construction. Samples D–31, D–32, and D–33 show methods of staking various other structures. Engineering notes—checking completed work Sample D–34 shows an example of recording a check of completed construction and, although an embank- ment is shown, the principles are applicable for all construction work. Some technicians develop a checkout schedule simi- lar to the stakeout schedule based on constructed fill height to the dam centerline. Use of such schedules may be appropriate for large complex dams. The notes shown, along with good visual judgment, should be sufficient for the ordinary dam. A plot of the planned embankment section overlain with the constructed cross section can also be made to visually compare the two.
