Book Description
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report outlines the HITEC Technical Evaluation Plan for large seismic isolator and energy dissipation devices. The plan is designed to characterize the fundamental properties and performance characteritics of a wide range of devices produced by U.S. and overseas manufacturers. It describes a program of full-scale dynamic tests, the results of which should provide guidance to the transportation-engineering community regarding the performance of large seismic devices.

Book Description
Prepared by CEITEC, a CERF innovation center serving the engineering and construction industries. This report describes an evaluation of Sewer Scanner and Evaluation Technology (SSET) designed to determine the basic capabilities and limitations of SSET for use as a technicallly viable technology for inspecting sewer pipes. The evaluation focused on the performance and in-service demonstration of SSET. The technology involves digital scanning to obtain a flat, "unfolded" image of the pipeline's interior. This evaluation includes field demonstrations performed at 13 municipal public works agencies throughout North America. Subsequent to this evaluation, SSET was modified to include a fisheye lens camera and fiber optic gyroscope, which replaced the rotating mechanical scanner and mechanical gyroscope. The evaluation confirmed the operability of SSET and its viability in data presentation. A degree of enhancement was recognized with additional features, most notably the ability to produce a digital report of the sewer pipe, to identify vertical deflection in pipes, and to deliver easily comprehensible and manageable results. The evaluation also revealed that SSET cannot reproduce all the features typically available from closed-circuit television (CCTV) inspection. Such features include the ability to clearly see corrosion, infiltration rates, and ovality. The limitations in applicability were determined and an economic comparison of SSET and CCTV is provided.

Book Description
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.

Book Description
Prepared by the Environmental Technology Evaluation Center (EvTEC), a CERF Innovation Center. This verification report describes a field evaluation of the installation of a silt fence using the Tommy? Silt Fence Static Slicing Method and compares this method to traditional trenching methods. The slicing method has been used extensively over the past few years but has not undergone a true field application test by a third party. State Departments of Transportation and federal, state, and local environmental regulatory agencies have expressed a desire and, in some cases, a need, for baseline environmental data providing a general picture of performance and feasibility of the Tommy Slicing Method for silt fence installation and erosion control.
