Scope of Work

Provide the design of the [soil] [rock] anchor system that will be completely the Contractor's responsibility. General design criteria are [shown on the drawings] [given in paragraph Design Requirements]. The materials, design, stressing, load testing, and acceptance must be in accordance with PTI DC35.1 and these specifications.

a. [Soil] [Rock] anchors may be threaded bar or strand type. The Contractor is responsible for the design of the anchor and bearing plate, [determining top of rock], determining drilling methods, and determining hole diameter and bond length. Submit design computations and data for the [soil] [rock] anchors, bearing plates, and bond zones.

b. Include computations with drawings, design assumptions, calculations, and other information in sufficient detail to verify the design proposed. The design must be certified by a registered Professional Engineer with proven experience in design of [soil] [rock] anchor components as stated in paragraph Qualifications. Include calculations for the stressing frames.

c. The Contracting Officer will approve the design calculations. Approval of the design calculations will not relieve the Contractor of responsibility for unsatisfactory performance of the installed [soil] [rock] anchors. Furnish all design computations at least [30] [_____] calendar days prior to the proposed commencement of drilling. The complete design, including design computations, fabrication and installation drawings and installation plan, must be certified by a registered Professional Engineer and must be submitted for approval.

d. Submit a plan for installing the [soil] [rock] anchors for review and comment. The proposal must describe the sequence for installation and other restrictions as outlined on the drawings or specified. Determine the anchor [and casing] installation procedures as part of the anchor design. Include the installation plan with descriptions of methods and equipment to be used for alignment checking of anchor holes [and casings].
