Section 207 Section 207 responsible for replacing or repairing the settlement plate(s) to the satisfaction of the Engineer at no additional cost to the State.
207.03.2 Monitoring. Monitoring of the settlement plate(s) will be done weekly
commencing immediately after each settlement pl ate is set and shall continue until a 180- day waiting period is completed. The 180-day waiting period does not begin until the surcharge construction is complete. The data shall be reported weekly to the Project Engineer for review. The data from the se ttlement plate(s) shall be forward to the Geotechnical Engineer, w ith copies to the Project Engineer , every 30 days for evaluation. Monitoring shall be performed from an esta blished survey location outside the limits of anticipated settlement.
207.04 Method of Measurement. Settlement plate, complete and accepted, will be
measured per each. No separate payment will be made for maintain ing, monitoring or reporting the settlement plate(s) data for the 180-day waiting period. Cost associated with maintaining, monitoring, and reporting se ttlement plate(s) data shall be included in the cost of the settlement plate. 207.05--Basis of Payment. Settlement plate, measured as prescribed above, will be paid for at the contract unit price per each, whic h shall be full compensation for furnishing labor, materials, equipment and services necessary to install, maintain, and monitor each settlement plate. Payment will be made under: 207-A: Settlement Plate - per each SECTION 209 - GEOTEXTILE STABILIZATION
209.01 Description. This work consists of furnishing and installing geotextile for
stabilization of embankments and subgrades as shown in the plans and in conformance with these specifications.
209.02 Materials . The geotextile and incidental materials for this work shall meet the
requirements of Subsection 714.13.
209.03 Construction Requirements . A subgrade that is to receive geotextile shall be
shaped and compacted to a smooth finish and free of loose material and sharp objects. An embankment site shall be cleared and grad ed to establish a relatively smooth surface. Trees and stumps are to be cut off at ground line and sawdust or sand placed over these areas to provide a cushion for the geotextile. The geotextile shall be placed as smooth as pos sible and free from tens ion, stress, folds, wrinkles or creases. Where more than one layer of geotextile is required, all joints of the bottom layer shall be sewn to develop the required geotextile strength perpendicular to the joint. The top layer and single layer installations of geotextile may be overlapped a minimum of two feet at each joint or sewn. Geotextiles that weigh less than eight ounces per square yard shall be factory or field sewn with a "J" type seam. Heavier weight geotextiles shall be factory sewn with two parallel bag type seams approximately one-four th inch apart or field sewn with an additional seam zigzagged across the two parallel seams. Securing pins with washers shall be inserted along a line through the mid-point of any overlap or sewn seam at intervals required by the Engineer to prevent movement of the geotextile until covered. The subsequent course of material shall be back-dumped in such a manner as to avoid damage to the underlying geotextile. No equipment will be allowed to operate over the geotextile until it is covered with a layer of material of sufficient thickness to protect the geotextile installation. When the underlying soil is very unstable, the two outer one-third portions of an embankment layer shall be pl aced approximately 25 feet in advance of the center one-third portion to prevent excessive mudwave movements and damage to the geotextile installation. The Contractor shall provide equipment necessary for placing the geotextile in the position and location as detailed on the plans. The geotextile shall be protected from contamination and damage during installation and placement of the specified cover material. Contaminated geotextile shall be replaced, and damaged geotextile shall be repaired or replaced as directed at no co st to the Department. The geotextile shall be covered with a layer of the specified material within 14 calendar days after placement. Geotextile not covered within this time period shall be removed and replaced at the C ontractor's expense.
209.04 Method of Measurement . Geotextile stabilization, placed in accordance with
these specifications and as directed by the Engineer, will be measured by the square yard of surface area covered. Any over width of material installed and additional material required for laps or sewing will not be measured.
209.05 Basis of Payment . Geotextile stabilization, measured as prescribed above, will
be paid for at the contract unit price per square yard, which price shall be full compensation for furnishing and placing the geotextile, pins, lapping, sewing, maintaining the geotextile until covered, and satisfactorily completing the work. Payment will be made under: 209-A: Geotextile Stabilization, Type ____, AOS * - per square yard * When not designated, see 714.13. SECTION 210 - ROADSIDE DEVELOPMENT
210.01 General Provisions . Where the term "plant establishment" is used, it shall be
understood to mean the work and time necessary to provide fully established, healthy vegetation.
