713.01 DESCRIPTION. Furnish, install, maintain, and remove

temporary construction barricades, precast concrete barriers, lights, signals, pavement markings, and signs; provide flaggers; and comply with all other requirements regarding the prote ction of the work, workers, and safety of the public. Unless otherwise noted in the plans or special provisions, this work also provides for traffic control management in compliance with the Manual On Uniform Traffic Control Devices (MUTCD), including the installation, inspection, maintenance, and removal of all traffic control devices relative to work on the project. Signs, barricades, barriers, channelizing devices, pavement markings, or any other temporary traffic control measures shall comply with pla n details, Temporary Traffic Control Standards , the MUTCD, and these specifications. Signs, barricades, barriers, channelizing devices, pavement markings, and arrangements thereof, as shown on the plans, are minimum requirements. Furnish and install appro priate signs for special conditions as directed. Requirements for proper signs, barricades, barriers, channelizing devices, or other safety precautions promulgated by the contractor ’s insurers are not negated by these specifications. These specifications shall not be construed to relieve the contractor of responsibilities for the safety of the public, for liability in connection therewith, or compliance with state and local laws or ordinances. Assign one or more authorized Traffic Control Supervisors (TCS) to provide traffic control management for the project. If assigning more than one TCS, then submit a weekly schedule identifying who will be in charge of providing traffic control management on a daily basis to the engineer. The TCS shall have a set of all contract documents relating to traffic control (and traffic staging if applicable), a current copy of the MUTCD, and a current copy of Temporary Traffic Control Standards readily available at all times. If a subcontractor provides traffic contro l management, the subcontractor’s TCS shall meet all the requirements set forth herein. The contractor may assign one or more Traffic Control Technicians (TCT) to assist the TCS in inspection and maintenance of Traffic Control Devices.

In case of a dispute over a rejected used sign, the engineer may take such measurements or review retroreflectivity and color data obtained by the contractor to determine if the sign meets minimum standards for new materials. Replace signs that do not meet the minimum standards for new materials at no direct pay. Rejected signs will be marked on the back “NOT FOR USE ON STATE PROJECTS. ” Remove signs placed by the contractor according to the Traffic Control Plan. The Department will ensure that all permanent highway signs are in place upon completion and prior to final acceptance of the project. On projects where constructing the surface course with asphalt concre te or portland cement concrete, install permanent striping and raised pavement markers (when required) prior to removal of barrica des. Upon removal, signs, barricades, and related devices furnished and placed by the contractor shall remain the contractor’ s property.

714.01 DESCRIPTION. Furnish, haul, plant, roll, water, and maintain

live grass sod at locations shown on the plans or as directed.

714.02 MATERIALS. Use approved sod consisting of either field grown

grass or nursery grown grass delivered in rolls or slabs. Field grown sod shall be Bermuda grass, carpet grass, or other approved grass native to the sodded area. Nursery grown sod shall be Centipede, Tifway Bermuda, Nomow Bermuda, Common Bermuda, or St. Augustine grass. Fertilizer shall comply with 1004.01 and agricultural lime shall comply with 1004.02 . Sod shall be free from noxious weeds or other vege tation. Obtain water from any source. Do not use brackish, chemically contaminated, or oily water.

714.03 GENERAL CONSTRUCTION REQUIREMENTS. Cut sod

with approved sod cutters. Mow the designated area when necessary. Cut sod to a minimum soil depth of 11/2 inches for field grown grass and 1 inch for nursery grown grass. Cut to a uniform width and in convenient lengths for handling. Retain soil on roots of sod when excavating, hauling, and planting. Obtain the services of an established soil testing entity to coordinate soil sampling, perform testing and analyses, and prepare recommendations for materials and procedures to be used during the pre- planting phase of new turf establishment. When practical, perform soil testing early enough to permit agricultural lime or other additives (if required) to be applied sufficiently in advance of planting so that the soil pH adjustment will occur before planting. Test and analyze samples to determine pH and fertility conditions. Use the test results and recommendations to determine the quantities of agricultural lime and fertilizer required for pre-planting applications. Furnish a copy of the test report with recommendations to the engineer. Testing will be at no direct pay. Consider probable time of application when making agricultural lime recommendations. Do not use sod cut more than 48 hours before placing unless authorized. Inferior appearing sod will not be accepted.
