Dear Construction Subscriber,

You are receiving this message from the Division of Construction
Publications Unit because you have subscribed to our Construction Manual
and other publications updates.

Below are summaries of new Construction Manual Sections 4-16, 4-49, and
4-50. We have revised and posted the sections at
http://www.dot.ca.gov/hq/construc/constmanual/.

4-16, “Clearing and Grubbing”


Clearing and grubbing work consists of cutting, removing, and
satisfactorily disposing of debris and vegetation, such as crops, weeds,
and other annual growth. It also includes filling holes and removing and
disposing of fences, walls, column footings, foundation slabs, signs, and
other rubble. Workers pay special attention to preserving property and
environmentally sensitive areas.

Section 4-49, “Piling”


The Standard Specifications section of the same name includes
specifications for cast-in-place concrete, steel, timber, and precast
prestressed concrete piling.

Section 4-50, “Prestressing Concrete”


A large percentage of the bridges built in California are prestressed,
post-tensioned type structures. The “Prestressing Concrete” section of the
Standard Specifications discusses prestressing precast or cast-in-place
concrete by tensioning prestressing steel.


While these manual sections contain no new policy, they have updated
language, information, and references, especially as they relate to the
2010 Standard Specifications. Publications staff have edited the sections
for plain language and format.


We invite your review of and feedback on these revisions. Please comment by
