555.1           GENERAL

                The Eccentric Loader Terminal (ELT) System is a non-proprietary guide rail end
                terminal used mainly as an approach end terminal for steel beam guide rail. It is also
                used in a standard transition from 3-cable guide rail to steel beam guide rail.

                Do not use ELTs with new installations of steel beam guide rail on roads with posted
                speed limits equal to or greater than 70 km/h. However, this restriction does not apply to
                the ‘Steel Beam With Eccentric Loader to 3-Cable’ transition treatment.

555.7           DESIGN

                The granular base and earth or rock slopes for the roadway shall be widened to
                accommodate the flare of the terminal in accordance with the minimum dimensions
                detailed in the appropriate Ontario Provincial Standard Drawing (OPSD).

                Where the roadway is being widened for installation of the terminal, ensure that
                drainage requirements are properly addressed.


555.8           COMPUTATION

                This is a Plan Quantity Payment item.

                The quantity is based on each completed installation.

                The unit of measurement for Eccentric Loader is each complete installation.


555.9           DOCUMENTATION

                Enter each ELT installation as a separate line entry under a single column heading on
                the "Quantities Miscellaneous" sheet showing the station at the back end (i.e. Post #6) of
                the ELT and location, left or right of centreline. Total the column and transfer the tender
                total to the tender document.

                Show locations of ELTs on the contract drawings with the Ontario Provincial Standard
                Drawing (OPSD) number shown adjacent to the symbol.

                Show the location of the embankment widening in the contract drawings (see section
                B206-1, "Earth Excavation (Grading)" for more information). Also, show embankment
                widening on cross-sections. Payment for all grading shall be made under appropriate
                grading items.

                Contracts where ELT posts and/or other underground hardware will require excavation
                of rock shall be noted in the Q-sheets, as stated in CDED B552-2 (Steel Beam Guide
                Rail) and Highway Design Bulletin 2006-001.

                When connecting adjacent Steel Beam Guide Rail to a concrete barrier or structure
                or applying “Steel Beam Installation – Entrances and Intersecting Roadways”, only
                the 7.62m long ELT installation is documented under the ELT tender item.
                Components not included in the ELT are documented under Steel Beam Guide Rail
                tender items (see CDED B552-2).

555.9.1         Documentation Accuracy

                Record stations to the nearest whole metre and indicate left or right side of road. The
                quantity is the number of units required.

                Offsets are specified on the OPSD and therefore are not to be shown on the quantity
                sheet.
