Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Service Center. This report summarizes the results of a detailedØevaluation of sliding isolation bearings,Ømanufactured by R.J. Watson, Inc. The report is part of a program to test the performance of 11 seismic isolators and dampers produced by several manufacturers. The devicesØwere tested for stability, response during earthquake simulations, and fatigue and weathering effects.

Presents the results of a detailed evaluation for one technology out of eleven that were evaluated. The evaluations were designed to test the performance of seismic isolators and dampers produced by several manufacturers.

Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF/IIEC Innovation Center This report describes a HITEC evaluation designed to determine the basic capabilites and limitations of the Geo-Con VERT Wall for use as a technically viable permanent excavation support retaining wall system. The evaluation was conducted based on design, construction, performance, and quality assurance information outlined in the HITEC Protocol. The Geo-Con VERT Wall System is an in-situ retaining wall system intended as an alternative to other types of cut walls such as soldier pile and anchored retaining walls. Geo-Con VERT Wall System is comprised of: deep soil mix columns consisting of overlapping or tangent soil-cement columns along the front face backed up by tangent rows of overlapping soil-cement columns; a soil-cement relieving platform overtop the columns; steel beams embedded in the front face soil-cement columns for support of the permanent facing; and permanent facing consisting of precast, reinforced concrete panels or reinforced cast-in-place concrete. The relieving platform is intended to provide internal stability by typing the soil-mix columns together and transferring the load to the bottom of the columns.

Prepared by the Environmental Technology Evaluation Center (EvTEC), a service center of CERF/IIEC. This Technology Verification report describes the nature and scope of the environmental evaluation of the performance of the Plasma Enhanced Melter? (PEM?) system for waste treatment. The evaluation was conducted through a cooperative program established in 1998 between the Washington State Department of Ecology, Integrated Environmental Technology Inc., Allied Technology Group, and the Civil Engineering Research Foundation. The goal of this report is to provide potential users and purchasers of the PEM? system with information they need to make more informed decisions regarding the performance of PEM? as an equivalent or alternative to incineration for treating hazardous waste.
