adjusted volume set point regulator and index scale. No obstruction shall be
placed near adjustment.
a. Operation. The induction unit shall provide a mixture of cool
primary air and relatively warm ceiling plenum air to the conditioned space.
This function shall be accomplished by permitting the cool primary air to in-
duce warm air from the ceiling plenum. The unit shall contain damper assem-
blies controlled by a thermostat. Two dampers linked together control the flow
of induced air from the ceiling plenum. One damper controls the amount of cool
primary air. Whenever the controls demand full cooling, the primary (cold)
damper is 100% open and the induced air dampers are fully closed. As a reduc-
tion in cooling capacity is required, the induced air dampers gradually open,
and the primary air damper gradually closes.

quirements of the sections entitled "Excavation, Filling and Backfilling" and
"Concrete Work". Concrete pavement shall be constructed to established lines
and grades and to the thickness, type and sections shown and detailed. Any por-
tion of slab which for any reason becomes cracked or checked, or the surface
of which does not conform to the specified requirements, shall be considered as
not in accordance with the intent of these specifications, and if so directed,
shall be removed and replaced at no cost to the Owner.
2. Concrete shall have a slump of one inch to 2� inches. Coarse aggregate
shall show a percentage of wear of not more than 40 when tested by the Los
Angeles Abrasion Test, ASTM Standard C 131-64T. Air entraining admixture shall
be added to all concrete for pavement as specified in section entitled "Concrete
Work".

quired crown and grade by use of an approved template. Excess material shall be
'removed; depressions shall be filled with concrete or with approved material
compacted as specified for subgrade preparation. Subgrade shall be sprinkled
in such manner and at such times as required to obtain a thoroughly moist but
not muddy condition when concrete is placed. If deemed necessary, subgrade shall
be sprinkled the evening prior to placing concrete. After moistening, particu-
lar care shall be used to maintain and protect a correct and unmarked surface.
4. Forms and Form Setting. Side forms shall be full depth with base width
equal to depth for forms up to and including eight inches; base width for deeper
forms shall be not less than eight inches. Use of crooked, bent or damaged forms
will not be permitted. Forms shall be cleaned and oiled before each using.
Forms shall be set exactly to grade and alignment, supported on properly com-
pacted material throughout entire length, and shall be approved before concrete
is deposited against them. Forms shall be tested for grade and smoothness by
the Contractor, using a 10 -foot straightedge, and shall not vary from a true
plane by more than 1/8 inch in a 10 -foot length; excess variation shall be cor-
rected by resetting. Shimming with pebbles or loose earth will not be permitted;
any form not having satisfactory bearing for full length shall be removed, the
bearing area reshaped and compacted and the form reset. Forms shall not be re-
moved until 12 hours after concrete has been placed; at temperatures below 50
degrees, forms shall not be removed for at least 30 hours. Adjacent lanes or
structures may be used in lieu of forms provided existing concrete is afforded
proper protection from damage, and further provided such surface does not vary
from a true plane by more than 1/8 inch in 10 feet. Allow existing concrete
to cure three to seven days before loading, depending on weather conditions.
The Contractor will be held strictly responsible for damage, for any reason, to
surface and edges of existing pavement.
5. Placing. Concrete shall be deposited and spread to prevent any segrega-
tion and to produce a uniform layer of concrete having a depth approximately
one inch greater than required for finished slab. Rakes shall not be used for
handling concrete. In order to prevent introduction of earth and other foreign
27-1
materials into the concrete, muckers shall confine their movements to the fresh
concrete. Whenever these men step out of the concrete, their footwear shall be
washed or otherwise cleansed thoroughly before returning to concrete. Repeated
carelessness in this detail will be deemed sufficient cause for replacing such
workmen. Reinforcing mesh shall be placed in slab by pouring bottom portion of
slab, striking it off at proper elevation for mesh, then placing mesh and pouring
top portion of slab. Placing reinforcing mesh on subgrade and then raising it
into concrete will not be allowed.
6. Finishing. Surface of concrete shall be finished by machine or hand
methods, operations and sequence being the same in either case; either method
shall result in a smooth uniform slab free from defects and irregularities.
Edges and joints shall be finished with an edger having a 3/8 -inch radius,
a. Screeding and Consolidation. Concrete shall be struck off and screeded
to such elevation that subsequent operations will leave the finished surface
with proper crown and at elevations shown. A uniform ridge of concrete at least
three inches in depth shall be maintained ahead of the full length of screed.
Surface shall be tamped or consolidated until concrete is as dense as possible.
Concrete adjacent to forms, bulkheads and joints shall be vibrated with an ap-
proved internal vibrator operating at a frequency of not less than 3,200 pulsa-
tions per minute. Internal vibrators will not be required adjacent to side
forms when tamping operations of finishing machine satisfactorily consolidate
concrete adjacent to side forms.
b. Longitudinal Flat Finishing. Following screeding and consolidating
operations, the longitudinal surface shall be smoothed and brought to a uniform
cross-section by the use of long handled wood or metal -clad floats operated from
each side of the pavement. Each pass shall extend from beyond the centerline
to the near edge of the lane and forward advance shall be limited to one-half
the length of the float. Long handled lutes, not less than 10 feet long, shall
follow the floating operation to straightedge the surface and to remove laitance
and free water. Slab surface shall be brought to final shape and crown, high
spots cut down, and low areas filled; adding concrete as required. Straightedging
and refloating shall continue until the entire surface is smooth and uniform,
using care to avoid depressions where tools initially contact the surface.
L. Belting. When water sheen has disappeared and just before concrete
becomes nonplastic, surface shall be belted with a 2 -ply canvas belt having
a width of at least six inches and a length two feet greater than slab width,
or with an approved rubber belt. Hand belts shall have suitable handles.
Belt shall be operated with short strokes across the lane and with a rapid ad-
vance parallel to the centerline. Belting shall produce a finished surface
having a uniformly fine granular or sandy texture.
7. Pavement Joints. Joints of various types shall be constructed to dimen-
sions and normal locations shown. Joints shall be straight, perpendicular to
the surface, and shall extend from edge to edge of the section. Edges of all
formed joints shall be rounded with an edging tool. Preformed expansion ma-
terial shall conform to the requirements of section entitled "Concrete Work".
Joints shall be finished as specified below.
27-2
a. Construction Joints shall be formed by a header having a trapezoidal
projection to form a keyway in the pavement edge. After removal of the form
and before any adjoining concrete is placed, the edge of new pavement shall be
primed with asphalt diluted with gasoline to a brushing consistency. At the op-
tion of the Contractor, construction joints may consist of a deformed metal strip,
similar in shape to the above specified header, held rigidly in place by suita-
ble steel pins, with its top edge at least �-inch below the finished surface.
The pavement immediately above the metal strip shall be finished with a 3/8 -inch
jointer and the crack primed and sealed.
b. Contraction Joints shall consist of grooves, either formed or sawn,
at Contractor's option.
(1) Formed Grooves shall be formed by raking out concrete, inserting
a wood or metal strip, and tooling and finishing the concrete adjacent to the
groove so formed until concrete is at prescribed elevation. Joint strip shall
remain in place until concrete has taken initial set.
(2) Sawn Grooves shall be formed by cutting a groove of indicated
dimensions in the hardened concrete with a power driven saw as soon as concrete
has hardened sufficiently to permit sawing. A chalk line or other suitable
guide shall be used to mark the alignment of the joint and the saw cut shall
be straight from edge to edge_of the pavement. Immediately after sawing each
joint, the saw cut and adjacent concrete surface shall be thoroughly flushed
with water until all waste from sawing is removed from the joint.
c. Expansion Joints shall be constructed at right angles to the center-
line of pavement unless otherwise specifically shown. All mesh reinforcing shall
terminate three inches each side of the joint. Preformed expansion joint
material shall be installed in lower portion of joint; top of preformed filler
shall be � inch below top of pavement. Remaining joint space shall be filled
with joint sealer.
8. Sealing Joints. The groove of expansion, construction and contraction
joints shall be thoroughly cleaned by approved methods and concrete faces shall
be surface dry. The groove shall be filled with pressure applied cold joint
sealing compound as specified in section entitled "Concrete Work". Joints shall
be filled to the limits shown and detailed, using care to avoid overfilling or
spilling. Excess or spilled material shall be removed immediately.
9. Curing. All concrete pavement shall be cured for a minimum of seven days
by an approved method which, in any case, shall be applied to the finished
surface soon enough after placing to prevent checking, cracking and loss of
water from the surface and edges of concrete during curing period. See section
entitled "Concrete Work".
