674.01 Description.
This Section shall cover the work of furnishing, erecting, maintaining, and removing construction safety fence as shown on the plans, or directed by the Engineer, for the purpose of directing pedestrian traffic safely thr ough construction work areas.
674.02 Materials.
Construction Safety Fence shall consist of a plastic, open -mesh fencing material, which shall be bright orange in color, and mounted on posts by means of adjustable belts or loops or other means that will sec urely hold the fencing in an upright position. Posts may be of any type material that will adequately serve the intended purpose for the duration of the project. Fence material shall weigh at least 12 pounds per 100 foot long roll (four foot wide roll) { 5.4 kg per 30 meter long roll} ({1.21 meter wide roll}). The Department has established a list (List V -7) of acceptable Construction Safety Fences. The Contractor may furnish any of the safety fences shown on this list. The list is given in the Department 's manual, "MATERIAL, SOURCES AND DEVICES WITH SPECIAL ACCEPTANCE REQUIREMENTS."
674.03 Construction Requirements.
Construction Safety Fence shall be installed as shown in the plans and as directed by the Engineer. The fence shall be continuous, four feet in height above the ground surface, and shall be spliced together only at support posts with a minimum 6 inch {150 mm} overlap. The maximum spacing between posts shall be 10 feet {3 meters}. The Contractor shall maintain the integrity of the fence as long as the engineer deems necessary and while construction or associated activities are ongoing in the vicinity of the area enclosed or delineated by the fence. The Contractor shall routinely inspect the fence and correct any deficienci es immediately. The fence shall remain in place until the Engineer directs that it be removed. The fence materials shall remain the property of the Contractor and may be reused at other locations, provided they are in satisfactory condition for reuse as de termined by the Engineer. Posts and the hardware for attaching the construction safety fence to the posts shall be considered a necessary requirement of the construction safety fence installation and no direct payment will be made for such.
674.04 Method of Measurement.
Construction Safety Fence will be measured in linear feet {meters} to the nearest 0.1 of a foot {0.1 meter} along the line of the completed fence.
674.05 Basis of Payment.
a.General . The unit price for Construction Safety Fence shall be payment in full for furnishing all materials and for all labor, tools, equipment, and incidentals necessary for performing all work involved in constructing, maintaining, removing, and disposing of the construction safety fence.
680.03 Construction Requirements.
b.Payment will be made und er Item No .: 674-A Construction Safety Fence - per linear foot {meter} SECTION 680 GEOMETRIC CONTROLS
680.01 Description.
When this item is included in the proposal, it shall consist of the Contractor furnishing, placing, an d maintaining construction stakes, lines, and grades necessary for establishing the accurate location of all features of construction.
680.02 Materials.
All materials needed in the performance of the work of Geometric Controls shall be furnished by the C ontractor.
680.03 Construction Requirements.
a.Determination of Lines and Grades . The Engineer will furnish centerline control points (P.C.s, P.O.C.s, P.T.s, P.O.T.s, etc.) at intervals determined necessary by the Engineer for the Contractor to establish alignment on all roadways. Where ramps, cross roads, service roads, etc. are geometrically tied to the mainline roadway, the Engineer will only establish control points along the mainline of the roadways. The Engineer will stake breaks of rights -of-way an d mark the clearing limits. Bench marks will be furnished at intervals along the project for vertical control. Sufficient design roadway cross section information (elevations, slope ratios, etc.) will be provided to enable the Contractor to establish grade stakes and slope stakes. Alignment data and flowline data for drainage structures (including box culverts) will be furnished by the Engineer. For each bridge site, except box culverts, the Engineer will furnish a minimum of two horizontal control points a nd one bench mark for vertical control.
b.Contractor's Responsibility .
1.Contractor's Responsibility for Establishing Geometric Controls . The Contractor shall be responsible for all layout and geometric control work necessary for construction of all ite ms of work. The Contractor shall use the plans, controls and other data furnished by the Engineer in establishing the required location of all features of the work. The Contractor shall be responsible for the utilization and preservation of all furnished controls. The Contractor shall replace State furnished control stakes or marks that are disturbed by the Contractor during construction.
2.Contractor's Responsibility to Check Furnished Controls . The Contractor shall check all furnished controls as a fir st order of work to be assured that they are accurate. The Contractor's use of all furnished points and marks for construction of the project shall be acceptance of the responsibility for the accuracy of these controls. By acceptance of responsibllity for the accuracy of the controls the Contractor waives all claims for extra compensation for corrective work if the controls are later found to be incorrect. All discrepancies shall be reported immediately to the Engineer in writing.
3.Setting Geometric Controls for Roadway Construction . The Contractor shall mark or monument the locations of the finished subgrade along the centerline, at the edges of lanes and at breakpoints. Markings or monuments shall be provided at intervals of 100 feet {30 m } on tangent alignments and at intervals of 50 feet {15 m} on curved alignments. The type of marking or monument shall be suitable for the purpose of checking the vertical and horizontal position of the location against the required position shown in the plans. The type of marking or monument shall be approved by the engineer prior to being set. The Contractor shall also mark or monument locations on each layer of soil or aggregate base at transverse breakpoints on these layers at intervals of 50 feet { 15 m}.
4.Setting Geometric Controls for Bridge Construction . For all bridge work the Contractor shall establish and maintain all horizontal and vertical control points, and furnish all lines and grades necessary for the bridge construction from the initia l layout
