wire; hold rigidly in place with metal chairs or spacers during placing of concrete.
2. Hold bars in beams and slabs to exact location during concrete placement. Use spacers. chairs,
or other necessary supports with the following tolerances:
a. Bars in Slabs and Beams:
1) Members 8 Inches Deep or Less: ± 1/4 inch.
2) Members 8 Inches to 2' -0" Deep: ± 1/2 inch.
3) Members More than 2' -G" Deep: ± 1 inch.
b. Lengthwise of Member. ± 2 inches.
a Concrete Cover to Formed Surfaces: ± 1/4 inch.
d. Minimum Spacing Between Bars: ± 1/4 inch.
B. Welded Reinforcement (AWS D1.4): Do not weld reinforcement in the shop or field.
3.05 PLACING CONCRETE
A. Notify Testing Laboratory minimum 24 hours prior to commencement of concreting operations.
B . Place concrete in accordance with ACI 301; including hot and cold weather placement procedures.
C. Ensure reinforcement, inserts, embedded parts and formed joints are not disturbed during concrete
i placement.
J
D. Place concrete in reasonably uniform layers, approximately horizontal, 12 to 18 inches thick, exercising
care to avoid vertical joints or inclined planes. Place concrete continuously between predetermined
construction ioints shown on structural drawings. Piling up of concrete in forms to cause separation or
loss of ingredients is not permittt d.
E. Do not deposit concrete which has partially set or hardened. Do not deposit Initial lubricating mortar
when pumping concrete. Remove hardened or partially hardened concrota which has accumulated on
forms or reinforcement. Do not place concrete on previously deposited concrete which has hardened
s,rfficiently to cause formation of seams ur planes of weakness within respective member or section
rxcept as specified.
F. Deposit concrete as nearly in final position as practical to avoid rahandling. Exercise care to prevent
splashing forms or reinforcing with concrete. Do not permit concrete to drop freely a distance greater
than 3 feet. Where longer drops are necessary, use chute, tremie, or other conveyance to help avoid
separation.
G. Co not deposit concrete into excavation where water is standing. If place of deposit cannot be
successfully pumped dry, place through tremie with outlet end near bottom of place of deposit.
i H. Do nc leposit concrete when plasticity, measured by slump tast, is outside specified limits.
I. Consolidate and screed concrete slabs -on -grade by use of vibratory screed of size to allow
construction joint pattern as indicated on Structural Drawings and specified.

3.06 FORM REMOVAL
A. Do not remove forms until concrete has attained sufficient strength. Clamps or tie rods may be
loosened 24 hours after concrete is placed. Ties, except for sufficient number to hold forms in place,
may be removed at that time.
B. Minimum Curing Period Prior to Form Removal:
1. Air Temperature: Above 60 °F: 3 days.
2. Air Temperature: 50 °F to 60 °F: 5 days.
3. Air Temperture: 40 °F to 50 °F: 7 days.
4. Air Temperature: Less than 40 °F: When temperature below 40 °F prevails, leave forms until
concrete reaches 75% of 28 -day design strength.
C. Observance of minimum curing periods listed above does not relieve Contractor of responsibility for
safety of structure during construction.
D. Remove wood forms from under floors, ramps, steps, and similar places (through temporary
openings it necessary) so no material will be left to rot or to be infested by termites.
3.07 FINISHING
A. Schedule of Finishes:
1. Interior Floor Slabs: Machine trowel.
2. Unexposed Exterior Formed Surfaces: Rough form finish.
3. Exposed Exterior Formed Surfaces: Rubbed/stoned.
4. Sidewalks: Light broom.
5. Ramps and Steps: Heavy broom.
6. Exterior Garden Center Slab: Light broom.
B. Initial Working:
1. Remove surface irregularities with bull float before water appears on concrete surface.
2. Do no further working of surface until time for floating; do not work surface while water is present.
3. "Dry Sprinkle" method finshing is riot acceptable and will be cause for rejection.
C. Floating:
1. Begin float operations when bleed water sheen has disappeared and concrete has stiffened
sufficiently to allow walking on surface without leaving heel prints more than 1/4 inch deep. Use
magnesium or aluminum power float.
2. Premature finishing brings excessive fines to surface and causes finished slab to have soft
surface which wi!! dust.
D. Troweling:
1. Delay trowelling as long as possible to prevent working excess fines and water to surface. Do
not begin until surface moisture film and shine remaining after floating have disappeared.
2. Powr r hbwei where _possible; use hand trowel in inaccessible areas.
3. Do not over - trowel Stockroom floor. Slab must be able to accept specified floor treatment.
Coordinate with floor treatment manufacturer's epplica +lon instructions for proper finish and for
pprocedures when finish is too dense for proper floor treatment application.
4. Do not re--* ,t surface to trowel.
E. Provide ACI ' ;lass A" tolerance; 1/8 inch variation in 10 feet, measured with straight edge laid in any
direction.
F. Pitch to drains: Foam 18 inch radius around floor drains and pitch concrete surface to drains at rate of
1/4 Inch per foot nomin ?'.
G. Saw -Cut Control Joint -
1. Primary `;ethod: Soft -Cu' System method, by Soft -Cut International, Riverside, CA (800)776-
3328. Finisner must hav _ do-;umented successful experience in the use of this method prior to
this roject. Install cuts w; `in hours attar final finish at each saw cut location. Use 3/32 inch thick
blade, cutting a minimum of 5/8 inch to A maximum of 1 inch into slab.
2. Optional Method (Where Soff-Cut System Method Equipment is Not Available): Cutting shall
be timed properly with the set of the concrete. Saw -cut control joints within 12 hours after
finishing. Start cutting as soon as the concrete has hardened sufficiently to prevent aggregates
being dislodged by .' :,i saw. Complete cutting before shrinkage stresses becom3 sufficiant In
produce cracking. Usa 3/16 inch thick blade. cutting '1 -1/4 inch into slab.
