Title: CONTRACTING FOR TIEDBACK WALLS IN KENTUCKY
Accession Number: 00468617
Record Type: Component
Availability: Find a library where document is available Abstract: The Kentucky Transportation Cabinet has used a prebid design performance specification for two permanent tiedback walls. These walls were used for control or correction of active landslides. The walls comprised steel H-sections, timber lagging, and corrosion-protected tiebacks. Only approved tiedback wall contractors were permitted to participate in these projects. These approved contractors were given a packet of information on the projects. The packets contained all technical and administrative details deemed necessary to satisfactorily complete the work. Contractor input was solicited during development of the information packets. The contractors were to develop their own tiedback wall schemes. Tieback size, tendon type, bonded and unbonded length, and tieback location were their responsibilities. They were required to submit complete design calculations, construction plans, and any notes to the cabinet for review and acceptance 30 days before bids were opened. After design acceptance, the contractors were to prepare lump sum bids for their wall systems. On one wall contract the tiedback wall contractor was the prime contractor. On the other contract the wall contractor was a subcontractor. Both walls were completed satisfactorily. The cabinet is considering developing a post-bid design performance specification for tiedback walls. This would reduce the staff time involved in design review.
