Bridges - Steel Construction

Attributes. Main Article:Sustainable steel bridges Modern steel bridges taking advantage of the latest advances in automated fabrication and construction techniques are able to provide economic solutions to the demands of safety, rapid construction, aesthetics, shallow construction depth, minimal maintenance and flexibility in future use. Steel also scores well on all the sustainability CLEANING AND PAINTING EXISTING STEEL STRUCTURESOct 02, 2001 · CLEANING AND PAINTING EXISTING STEEL STRUCTURES Effective:October 2, 2001 Revised:October 23, 2020 Description. This work shall consist of the preparation of all designated metal surfaces by the method(s) specified on the plans. This work also includes the painting of those designated surfaces. Chapter 5 Quantities Calculations- Estimate the area of steel requiring spot cleaning for each element. Include the estimate for each item in a note or, on projects with several structures, in a table on the Title Sheet. In the Estimate column of the quantity block, show the accumulated sum of all areas requiring spot cleaning.
