purposes may be included in the plans. Design, fabricate, install, maintain , and remove the cofferdam system. The cofferdam system consists of temporary elements such as walls, supporting structural elements, and water control system. The cofferdam seal is part of the permanent structure designed by the EOR. The seal is designed to prevent water ingress and to provide vertical stability to the cofferdam system and foundation during all construction stages. Place the upper one foot of seal concrete in the dry to provide a level surface for forming and constructing the foundation footing. The plan seal and foundation have been designed for vertical stability under the plan specified maximum allowable water surface elevation for dry foundation construction. Flood the cofferdam when the water elevation exceeds the specified maximum allowable water surface elevation. Flooding under this condition will be considered an excusable compensable delay in accordance with 108.07.4 . Cofferdam flooding occurring at water elevations below the specified maximum allowabl e value will be considered a non-excusable delay in accordance with
108.07.5 .
Alterations to the plan seal and foundation will require a Contractor or VE Proposal. Submit the proposal for review. The specified maximum water surface elevation will not be altered. Department cost to review, redesign and detail the seal and foundation will be reimbursed to the Department through Change Order regardless of whether or not the proposal is constructed. Submit a Cofferdam Installation Plan to the Project Engineer for record. Include design assumptions, computations, details of cofferdam system elements, and sequences and methods of construction including excavation, installation of cofferdam system, and construction of seal and foundation, and cofferdam system removal. Include cofferdam system components to remain in the perman ent work, repair methods and repair materials. The Cofferdam Installation Plan shall be designed, sealed, signed and dated by a professional engineer registered in Louisiana. Design and construct cofferdam so that system and components safely perform under all aspects of global, external and structural stability during each stage of construction, including anchorage, embedment, and loads from balanced and unbalanced soil, water, and construction activities. Provide sufficient interior clearances for form construction, inspection of form exteriors, and to permit control of water. Cofferdams that tilt or move laterally shall be righted, reset, and enlarged as needed to provide necessary interior clearances. Control ingress of water so that construction can be performed in the dry. Dewater after seal concrete has cured. When weighted cofferdams are employed and the weight is utilized to participate in vertical stability of the system, provide anchorage to transfer cofferdam system weight to the seal. During placing and curing of seal, control the water elevation inside the cofferdam to prevent water flow through the seal. If the cofferdam is permitted by the engineer or required by the plans to remain in place, vent or port cofferdam at or below low-water level. Re-establish pre-construction ground elevations inside and outside of the cofferdam in accordance with Section 802 . Remove cofferdam system after completion of the work without damaging the finished work or existing adjacent structures. Portions of the cofferdam system which remain within concrete perman ent work in accordance with the Cofferdam Installation Plan shall be removed to at least 6 inches from the surface of the permanent work. Use block outs to facilitate removal and patch permanent work with compatible materials conforming to the plans and the Cofferdam Installation Plan.
817.03.2 5 Water Control Systems :
817.03.2 5.1 Well Point System : When required by plans or the
engineer, a well point system shall be designed, detailed, installed, maintained, and removed by the contractor. Install the well point system arou nd the perimeter of the excavated area in a location such that other operations will not be impeded.

When well poin ts are no longer required for water control, plug abandoned well in accordance with 202.06 . Install piezometers or other suitable means of monitoring within the exc avated area as required by field conditions. Make daily readings or measurements of the piezometers to verify that the well point system is operational. Excavation may begin when the level is 5 feet below the proposed excavation bottom surface for at least four hours. Provide the well point system with a back -up system of pumps and power units. If failure of the well point system occurs, add water to the excavation as rapidly as possible at no additional cost or time to the Department. Notify the enginee r after completing each excavation. Do not place concrete until the engineer has accepted the excavation.
817.03.2 6 Cleaning and Painting Containment Systems : General
containment system requirements for bidding purposes may be included in the Control ingress of water so that construction can be performed in the dry. Dewater after seal concrete has cured.
