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
Revised 6/15/17 Contract No. 6062 Page 179 of 210
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.
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 b ridging 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 bridg- ing 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.
Add the following section:
306-1.1.7.2 Additional Requirements. In all cases when the depth of the trench exceeds the width of the steel plate bridging resting on each side of the pavement adjacent to the trench, safety regulations require or the Engineer determines that shoring is necessary to protect the health or safety of workers or the public the Contractor shall install shoring conforming to Section 7-10.4.1 of the Standard Specifications. The trench shoring shall be designed and installed to support the steel plate bridging and traffic loads. All approvals for design, substitution of materials or methods shall be submitted by the Contractor in accordance with all provisions of section 2 -
5.3 Shop Drawings and Submittals. The Contractor shall backfill and resurface excavations in accordance with section 306-1.5.
Add the following section:
306-1.1.7.3 Installation. When backfilling operations of an excavation in the traveled way, whether transverse or longitudinal cannot be properly completed within a workday, steel plate bridging with a non- skid surface and shoring may be required to preserve unobstructed traffic flow. In such cases, the following conditions shall apply:

2. Steel plates used for bridging must extend a minimum of 610 mm (2’) beyond the edges of the trench.
3. Steel plate bridging shall be installed to operate with minimum noise.

ABC CONTRACTORS
OFFICE # (760)XXX-XXXX
FIELD # (760)XXX-XXXX
Dear resident:
As a part of the City of Carlsbad’s ongoing
program to maintain its streets, your street will be
resurfaced with asphalt concrete over the existing
roadway surface. This construction will require
the closing of your street to through traffic for one
day. Your street, from XYZ St. to DEF Ave. will be
closed to through traffic and resurfaced on:
MON. TUE. WED. THU. FRI.
DATE: _XX / XX / XX______________
from 7:00A.M. to 5:00 P.M.
If you don’t plan to leave your home by 7:00 A.M.
on the above date please park your car on an
adjacent street in your neighborhood that will not
be resurfaced. Streets scheduled for resurfacing
can be determined by calling either the
Contractor or t he City of Carlsbad’s Project
Inspector. When walking to and from your car,
remember not to walk on the newly overlaid street
or you will have black residue on the bottom of
your shoes. Please do not drive, walk on, walk
pets, play, or skate on the newly overlaid asphalt.
Also, please refrain from watering your lawns,
washing cars, etc., approximately 6-8 hours after
the asphalt is laid as running water will cause
damage to the new surface.
ABC is the Contractor that will be performing the
resurfacing work for the city and you may call
them at the above phone number if you have any
questions regarding the project. Resurfacing of
your street will not occur on the day your trash is
collected. Mail delivery may be delayed if the
postman cannot reach the mailbox that day. If you
have a moving company scheduled for that day
please call and inform the Contractor of the date.
If you have any concerns which cannot be
addressed by the Contractor, you may call the
City’s Project Inspector @ (xxx) xxx-xxxx.
Thank you for your cooperation as we work to
make a better City of Carlsbad.
