    SHORING AND BRACING

   PART 1 - GENERAL

   1. . SECTION INCLUDES

    A. Sheet piling, shoring and bracing necessary to protect existing buildings, streets, walkways, utilities, and other improvements and excavation against loss of ground or caving embankments.

    B. Maintenance of bracing, as required.

    C. Building excavation is specified in another Division-2 section.

   1. . QUALITY ASSURANCE

    A. Supervision: Assign supervision of shoring and bracing work to a qualified foundation consultant.

    B. Regulations: Comply with local codes and ordinances of governing authorities having jurisdiction.

   1. . SUBMITTALS

    A. Design Drawings: Provide design drawings for shoring and bracing system and other data prepared and sealed by a registered Professional Engineer. System design and calculations must be acceptable to local authorities having jurisdiction.

   1. . JOB CONDITIONS

    A. Before starting work, check and verify governing dimensions and elevations. In company with Engineer, jointly survey condition of adjoining properties. Take photographs, as directed by Engineer, recording any prior settlement or cracking of structures, pavements, and other improvements. Prepare a list of structures, pavements, and other improvements. Prepare a list of such damages, verified by dated photographs, and signed by Contractor and Engineer and others conducting the investigation.

    B. Survey adjacent structures and improvements, establishing exact elevations at fixed points to act as benchmarks. Clearly identify benchmarks and record existing elevations. Locate datum level used to establish benchmark elevations sufficiently distant so as not to be affected by movement resulting from excavation operations.

    C. During excavation, resurvey benchmarks weekly, employing a licensed Land Surveyor or registered Professional Engineer. Maintain accurate log of surveyed elevations for comparison with original elevations. Promptly notify Engineer if changes in elevations occur or if cracks, sags or other damage is evident.

   1. . EXISTING UTILITIES

    A. Protect existing active sewer, water, gas, electricity and other utility services and structures.

    B. Notify municipal agencies and service utility companies having jurisdiction. Comply with requirements of governing authorities and agencies for protection, relocation, removal and discontinuing of services, as affected by this work.

   PART 2 - PRODUCTS

   2.01 MATERIALS

    C. General: Provide suitable shoring and bracing materials which will support loads imposed. Materials need not be new, but should be in serviceable condition.

   PART 3 - EXECUTION

   3.01 SHORING

    D. Protect the site from caving and unacceptable soil movement. Wherever shoring is required, locate the system to clear permanent construction and to permit forming and finishing of concrete surfaces. Provide shoring system adequately anchored and braced to resist earth and hydrostatic pressures. Contractor shall be responsible for tying sheet piling back to bulkhead.

    E. Shoring systems retaining earth on which the support or stability of existing structures is dependent must be left in place at completion of work. If wood is part of the shoring system near existing structures, use pressure preservative treated materials or remove before placement of backfill.

   3.02 BRACING

    F. Locate bracing to clear columns, floor framing construction, and other permanent work. If necessary to move a brace, install new bracing prior to removal of original brace.

    G. Do not place bracing where it will be cast into or included in permanent concrete work, except as otherwise acceptable to Engineer.

    H. Install internal bracing, if required, to prevent spreading or distortion to braced frames.

    I. Maintain bracing until structural elements are rebraced by other bracing or until permanent floor construction is able to withstand lateral earth and hydrostatic pressures.

    J. Remove sheeting, shoring and bracing in stages to avoid disturbance to underlying soils and damage to structures, pavements, facilities, and utilities.

    K. Repair or replace, as directed by Engineer, adjacent work damaged or displaced through the installation or removal of shoring and bracing work.

    END OF SECTION

Rembco Geotechnical Contractors specializes in slope stabilization, foundation repair and support, shoring, grouting, soil nails, micropile installations, and sinkholes. We are experienced in these applications: micro piles, sinkhole repair, permeation grouting, pressure grouting, soil nails, chemical grouting, micropiles, compaction grout, rock anchors and compaction piles. Our specialties are rock anchor, chemical and compaction grouting, mini piles, sinkhole repair, micropiles, and soil nailing. We use a problem-solving approach in the geotechnical portions of buildings, bridges, water plants, sewage plants, tunnels, sinkholes, caisson, and roads. Rembco techniques apply when adding new real estate structures: especially rock anchor, microfine grouting, soil nailing, micropile installations for foundation support.
