steel plate bridging. The Contractor shall not employ the use or use steel plate bridging or trench plate that does not meet the requirements of this section both in application and circumstance of use.
Add the following section: 306-1.1.7.1 Requirements for Use. Alternate construction methods that avoid the use of steel
plate bridging shall be used by the Contractor unless otherwise approved by the Engineer. It is recognized that to accommodate excavation work, steel plate bridging may be necessary. All conditions for use of steel plate bridging set forth in the following requirements must be
fulfilled as conditions of approval of the use of steel plate bridging. Consideration of steel plate bridging in the review process will take into account the following factors: 1. Traffic volume and composition. 2. Duration of use of the steel plate bridging. 3. Size of the proposed excavation. 4. Weather conditions. The following formula shall be used to score the permitted use of steel plate bridging:
PS = [ ADT + EWL + DAYS + 10 X WEEKEND + 5 X NIGHTS + 20 X WEATHER + SPEED (kmh) + SLOPE X 100] X LANES 1000 8 PS = [ ADT + EWL + DAYS + 10 X WEEKEND + 5 X NIGHTS + 20 X WEATHER + SPEED (mph) + SLOPE X 100] X LANES 1000 5 where:
PS = plate score. ADT = average daily traffic as defined in the Federal Highway Administration (FHWA) Manual on Uniform Traffic Control Devices (MUTCD) 2003 Edition as amended
by the MUTCD 2003 California Supplement. EWL = equivalent wheel loads as defined in the Federal Highway Administration (FHWA) Manual on Uniform Traffic Control Devices (MUTCD) 2003 Edition as amended
by the MUTCD 2003 California Supplement. DAYS = total number of 24 hour periods during which the plates will be utilized at the site being considered.
WEEKEND = total number of Saturdays, Sundays and holidays that the plates will be utilized at the site being considered. NIGHTS = total number of overnight periods that the plates will be in place, exclusive of
Saturday, Sunday and holiday nights. WEATHER = total number of 24-hour periods that the plates will be utilized at the site being considered when the possibility of rain exceeds 40 percent. SPEED = the design speed in kilometers per hour or miles per hour, as applicable in the formulae above, of the street where the plates are to be installed. This number shall not be reduced for construction zone speed reductions.
Revised 6/15/17 Contract No. 6070 Page 49 of 59
SLOPE = the quotient of the vertical differential divided by the horizontal distance. The vertical and horizontal dimensions shall be measured at the locations spanning
a distance of 15 m (50’) up and downstream of the position of the proposed steel plate bridging. LANES = the number of lanes where plates will be used.
When the computed value of the plate score exceeds 50, steel plate bridging shall not be used unless, and at the sole discretion of the Engineer, the Engineer determines that no alternative
method of construction is possible in lieu of using steel plate bridging or that other overriding considerations make the use of steel plate bridging acceptable. Alternatives considered to bridging shall include, but not be limited to, detouring traffic, construction detour routes, tunneling, boring and other methods of trenchless construction. Unless specifically noted in the provisions of the Engineer's approval, the use of steel plate bridging at each location so approved shall not exceed four (4) consecutive working days in any given week.
