SECTION II: GENERAL PROVISIONS
WOODRUFF DRAINAGE CONSTRUCTION, NAVAJO COUNTY, ARIZONA,
CONTRACT #B26-04-029
This is an invitation for bids for the construction of drainage improvements that include
installation of concrete channel lining, storm drainpipe, culverts, pavement replacement, and
associated site work. The project consists of installing 2,392 square yards of 4-inch-thick concrete
channel lining; one (1) manhole; two (2) valve boxes with covers; a drainage structure headwall;
five (5) catch basins; one (1) drop inlet structure; fourteen concrete end sections; and sixteen 18-
inch diameter flared end sections. Work also includes installing 1,153 linear feet of 24-inch storm
drainpipe (HDPE), 813 linear feet of 18-inch storm drainpipe (HDPE), and 427 linear feet of
reinforced concrete pipe.
Additional work includes placing 389 tons of asphaltic concrete; installing 106 square yards of 9-
inch Portland cement concrete pavement; and placing 861 cubic yards of Class 2 aggregate base.
The contractor will also saw cut and remove 2,259 square yards of asphaltic concrete pavement,
clear and grub the project area, remove 352 linear feet of existing pipe, excavate 924 cubic yards
of drainage ditch, and remove two existing catch basin structures. Construction surveying and
layout are also required.
Due to local wildlife, certain precautions must be taken:
* No construction activities shall occur between April 1 - September 30 of any
calendar year to avoid impacts to the Southwestern Willow Flycatcher and the Yellow-
Billed Cuckoo, species protected under the Endangered Species Act.
* The contractor shall not cause injury or death to swallows, including eggs and
nestlings, and shall avoid work within fifty (50) feet of nesting swallows from February 1
to August 31 of any calendar year.
* If active bird nests are identified within the project limits, construction activities
will avoid disturbing any active nest. Avoidance areas, if necessary, will be marked in
the field with temporary fencing or t-posts with flagging. The engineer will confer with
the approved biologist to determine the appropriate avoidance strategy until the
nestlings have fledged from the nest and the nest is no longer active.
* To prevent the introduction of invasive species seeds, all earthmoving and hauling
equipment shall be washed prior to entering the construction site, and the contractor
shall inspect all construction equipment and remove all attached debris, including
plant parts, soil, and mud, prior to the equipment entering the construction site.
