Construction Method. Excess material shall not be sidecast onto slopes greater than 65%. On side slopes exceeding 50%, new roads shall be full bench construction, keeping sidecast to less than three feet in thickness by drifting excess excavated material along the road surface or utilizing it as fill elsewhere. Length of through-cut sections shall be minimized, and shall in no case be longer than the standard waterbar spacing unless provision is made for disposal of road surface water.
Construction Method. 2.4.1.1 Construction of the promenade with public landing facility and the breakwater will mainly involve dredging of seabed, underwater rock excavation, construction of sloping seawall, pile construction and construction of deck structures. The improvement works for the existing lookout points and the existing viewing platform will involve demolition of existing structures, installation of new concrete structures and backfilling. To minimise the potential environmental impacts, the following construction methods and sequences have been considered and adopted for the Project as far as possible: Minimise active marine works area by phased construction and adopting piled deck structure for the public landing facility and breakwater to reduce the amount of dredging works; Utilise pre-cast elements for construction of the public landing facility and breakwater as far as practicable to minimise in-situ construction works so as to reduce the construction period and environmental impacts, such as waste generation, noise and dust impacts; Incorporate ecological features such as seawall enhanced with rough texture and irregular pattern into the design of vertical seawall as far as practicable to provide shades and refuge for organisms. A submission on the detailed design of the ecological features to be adopted will be prepared subject to comment by the AFCD prior to the installation of the ecological features; Install silt curtain and restrict dredging operation to a production rate of no more than 100m3 per hour to minimise the potential water quality impact (e.g. prevent the dispersion of suspended sediments) arising from the dredging works; and Implement good site practice and appropriate environmental mitigation/control measures.
Construction Method. Demonstrate the ability to achieve desired surface inside each depression without tearing or snagging the asphalt prior to beginning the work. Provide rumble strips that shall have finished dimensions of seven inches (± ½ inch) long in the direction of travel and are a minimum of 12 inches wide measured perpendicular to the direction of travel. Provide rumble strips having depressions with concave circular shape with a minimum ½-inch depth at center (maximum allowable depth of 5/8-inch). Place rumble strips in relation to the roadway according to the patterns shown in Standard Drawing 665.01 and the Rumble Stripes Detail included herein. Material resulting from the operation shall become the property of the Contractor. Remove and dispose of this material in accordance with Section 802 of the current edition of the Standard Specifications. At the end of each working day, remove all equipment to a location where it does not present a hazard to traffic, clean the pavement by sweeping or flushing, and reopen the work area to traffic. Measurement and Payment
Construction Method. SBH shall collaborate with the City and consider in good faith the City’s input on choosing the construction method that minimizes the likelihood of exceeding the Approved Budget while at the same time ensuring completion of the ESC by the Outside Completion Date.
Construction Method. Turbidity Barrier shall be installed and maintained conforming to WI DNR Conservation Practice Standard 1069 – Turbidity Barrier.
Construction Method. E23.5.1 Handle and use treated and non-treated wood in a manner which will avoid damage or field fabrication causing alteration in original treatment.
Construction Method. E28.3 The Contractor shall supply, place and compact the 6 mm down limestone material in accordance with CW 3110, Base Course. MEASUREMENT AND PAYMENT
Construction Method. Demonstrate the ability to achieve desired surface inside each depression without tearing or snagging the asphalt prior to beginning the work. Provide rumble strips that shall have finished dimensions of seven inches (± ½ inch) long in the direction of travel and are 8 inch or 12 inches (± ½ inch) wide measured perpendicular to the direction of travel. Provide rumble having depressions with concave circular shape with a minimum ½-inch depth at center (maximum allowable depth of 5/8-inch). Place rumble strips in relation to the roadway according to the patterns shown in Standard Drawing 665.01. The Contractor’s attention is directed to the fact that the existing paved shoulders vary in width. The Contractor shall install 8 inch wide shoulder rumble strips in sections that have less than 2 ft. paved shoulder, 12 inch wide shoulder rumble strips in sections that have a 2 ft. to less than 4 ft. paved shoulder and 16 inch wide shoulder rumble strips in sections that have a 4 ft. or greater paved shoulder, or as directed by the Engineer. Material resulting from the operation shall become the property of the Contractor. Remove and dispose of this material in accordance with Section 802 of the Standard Specifications. If milled rumble strips are installed with the intent of placing thermoplastic pavement markings over the milled-in rumble strips, the Contractor shall remove all debris after milling to ensure optimum adhesion between the surface and the thermoplastic. At the end of each working day, remove all equipment to a location where it does not present a hazard to traffic, clean the pavement by sweeping or flushing, and reopen the work area to traffic. Measurement and Payment
Construction Method. The production borehole shall be constructed using reverse rotary drilling equipment. The borehole shall be drilled at a diameter of 30-inches to a depth of 370 feet.
Construction Method. At the completion of the drilling and geophysical operations, the Contractor will prepare the borehole for casing installation. The Contractor shall insure that all cuttings have been removed from the borehole. During the electric log and caliper survey, the borehole shall be kept full of drilling fluid. The Contractor will not be required to return to bottom with the drilling tools if casing installation immediately follows the caliper survey, assuming acceptable results are achieved.
