Xxxxxxxx and Bracing. 1. Design, furnish, place, maintain, and subsequently remove, to extent required, a system of temporary supports for cut and cover, open cut, or trench excavations, including bracing, dewatering, and associated items to support sides and ends of excavations where excavation slopes might endanger in-place or proposed improvements, extend beyond construction right-of-ways, or as otherwise specified or indicated.
2. Provide all materials on Site prior to start of excavation in each section, and make such adjustments as are required to meet unexpected conditions.
3. Space and arrange sheeting and bracing as required to exclude adjacent material and according to stability of excavation slopes.
4. Assess existing conditions including adjacent property and possible effects of proposed temporary works and construction methods; and select and design such support systems, methods, and details as will assure safety to the public, adjacent property, and the completed Work.
5. Use caution in areas of underground facilities, which shall be exposed by hand or other excavation methods acceptable to Design-Builder or Owner.
6. Perform sheeting, shoring, and bracing in accordance with safety and protection requirements of the Contract Documents. Inasmuch as earth retaining structures are required, whether temporary or permanent, these structures will be designed and stamped by a Professional Engineer registered in the state of Kansas in conformance with OSHA 29CFR1926.65.
7. Provide sheeting, shoring, and bracing for trench excavation in subgrade of excavation when required to prevent movement of the main excavation support system.
8. Provide shoring, sheeting, and bracing as indicated or as needed to meet the following requirements:
a. Prevent undermining and damage to all structures, buildings, underground facilities, pavements, and slabs.
b. Perform excavations with vertical banks where necessary for construction activities or as indicated, and also within all limits of excavation noted on Drawings.
c. Design excavation support system and components to support lateral earth pressures, unrelieved hydrostatic pressures, utility loads, traffic and construction loads, and building and other surcharge loads to allow safe and expeditious construction of permanent structures without movement or settlement of the ground, and to prevent damage to or movement of adjacent buildings, structures, underground facilities, and other improvements. Design shall account for staged removal ...
