About this file

Written by GovTribe AI · Apr 3, 2024

This document contains the standard plans for details related to the guardrail anchorage and bridge details for a state transportation agency. The plans include specifications and drawings for connecting guardrail types B, T, and MGS-8 to various bridge barrier railings and filler walls. The plans provide details on post spacing, beam elements, expansion sections, and hardware requirements. This information would be used for an as-needed guardrail maintenance contract in Baraga and Houghton Counties in Michigan. The contract would cover the installation, repair, and maintenance of guardrail systems on state roads and bridges within these two counties. The contract term and pricing details are not provided in this document.

REMOVE ALL EXISTING GUARDRAIL BETWEEN EXISTING SPLICES

BRIDGE RAILING LENGTH

INSTRUCTIONS FOR LAYING OUT RETROFIT

SPLICE BACK TOWARD THE BRIDGE.

1. MEASURE THE APPROPRIATE "Z" DISTANCE FROM ONE END OF THE BRIDGE RAILING AND LOCATE THE FIRST EXISTING

3. REPEAT STEPS 1 AND 2, FROM OPPOSITE END OF THE BRIDGE TO OBTAIN "Y" DIMENSION.

THIS DIMENSION WILL VARY FROM 0 TO 12'-6".

2. FROM THIS SPLICE, MEASURE THE SAME "Z" DISTANCE BACK TOWARD THE BRIDGE TO OBTAIN THE "X" DIMENSION.

4. SUBTRACT THE SUM OF "X" + "Y" FROM BRIDGE RAILING LENGTH. THIS WILL BE THE BRIDGE RETROFIT LENGTH.

THE REMAINDER WILL BE THE LENGTH OF A SHORTENED ELEMENT.

5. DIVIDE THE BRIDGE RETROFIT LENGTH BY 12'-6" TO OBTAIN THE NUMBER OF BEAM ELEMENTS PLUS A REMAINDER.

IN STEP 5.

RETROFIT WILL CONTAIN TWO SHORTENED BEAM ELEMENTS WITH ONE LESS 12'-6" BEAM ELEMENT THAN CALCULATED

6. WHEN THE REMAINDER IS LESS THAN 2'-6", ADD 12'-6" TO THE REMAINDER AND DIVIDE BY TWO. THE BRIDGE

Z = 56'-3" WHEN CONNECTING TO BEAM GUARDRAIL, TYPE B. USE GUARDRAIL ANCHORAGE, BRIDGE, DETAIL A5

Z = 50'-0" WHEN CONNECTING TO BEAM GUARDRAIL, TYPE T. USE GUARDRAIL ANCHORAGE, BRIDGE, DETAIL A4
