An independent testing agency shall cast 4 six inch test cylinders (5 if 56 day strength is allowed) or an additional cylinder iffour inch cylinders are used, for each 75 cubic yards of each concrete mix placed or for each day's operation, whichever is the lesser amount. The testing agency shall cast, cure, and test the specimens in accordance with ASTM C31 and ASTM C39. Air, temperature, and slump shall be tested at minimum for the first truck and every third truck thereafter (1st, 4th, 7th, etc.) or when a change in properties is noticed, at the final location (test after pump, not at truck).

2. The contractor shall be responsible for the design of formwork to comply with the dimensions indicated on the plans, maintaining proper alignment during.

All concrete except as noted in the following paragraphs shall meet the following requirements:

• Compressive Strength f’c = 4,000 PSI min at 28 days

• Water / (cement + pozzolan) ratio 0.45 max (0.40 max if exposed to sulfates)

4. Concrete used in exterior flatwork and stoop slabs shall meet the following requirements:

6. Concrete and grout exposed to frost (including foundation walls) shall be air entrained 6% +/- 1%.

7. Slump shall be 4 inches +/- 1 inch without water reducing admixtures. With water reducing admixtures, concrete mix design shall state design slump and field tests shall be +/- 1 inch. Slump is used primarily as a measure of concrete consistency, truck to truck. If slump is outside these ranges, water content (water: cementitious ratio) shall be checked against allowable; and concrete rejected, accepted, or adjusted on that basis.

8. Mix designs shall take account of heat of hydration in mass concrete (over 28 inches thick).

9. Water-reducing admixtures conforming to ASTM C494 added to the mix at manufacturer's dosage rates may be used for improved workability.

10. Do not add water to concrete at the jobsite without written approval of the SER, and in no case in excess of the water in the approved mix design.

11. No chloride containing admixtures are allowed.

12. Concrete used in areas subject to de-icing salts (including stoop slabs, exterior stairs, aprons, and reinforced sidewalks) shall have Cortec MCI added to the mix at manufacturer’s recommended dosage rates.

13. All concrete is normal weight unless specifically noted otherwise.

14. Cement shall be Portland cement type 1 conforming to ASTM C150 or Portland Limestone Cement type 1L conforming to ASTM C595. Up to 30% cement can be replaced with flyash and up to 50% with GGBFS (50% combined max.). Aggregate for normal weight concrete shall conform to ASTM C33. Water is to be potable or demonstrated to have no harmful effects on concrete. Fly ash shall be demonstrated by test to contain minimum 18 percent CAO except as noted in next paragraph. When fly ash is used in concrete to be air entrained, air entraining shall be adjusted as required for LOI per recent experience of ready mix supplier.

15. For structures exposed to hydrogen sulfate or soil sulfates, cement shall be Portland cement type 2 conforming to ASTM C150, with C3A content less than 8% by mass. Between 30% and 40% of cement shall be replaced with class "F" flyash with CAO content not exceeding 15%; and up to 10% with GGBFS with Al2O3 content less than 11 percent by mass (50% combined fly and GGBFS max.). Maximum w/(c+p)=0.40. Air entrain 7% +/-1.5%, adjusting as required for fly ash content. Aggregate for normal weight concrete shall conform to ASTM C33. Water is to be potable or demonstrated to have no harmful effects on concrete. Fly ash used in concrete to be air entrained shall have air entraining adjusted as required for LOI per recent experience of ready mix supplier.

16. Measured from the time water and cement are batched together, no more than 90 minutes shall elapse until concrete is placed. This time shall be reduced by two minutes for every degree that concrete temperature exceeds 75 degrees Fahrenheit. These criteria may be relaxed by the use of set-controlling admixtures.

17. Protect concrete in accordance with ACI 305 and ACI 306 for hot weather concreting and cold weather concreting respectively. In cold weather, heat is required if outside temperature falls below 30 degrees any time during first three days. Reinforcing shall be 40 degrees or warmer at time of concrete placement. Concrete temperature shall be recorded every morning and shall be kept above 40 degrees in all locations for 7 days. Concrete shall not be exposed to combustion products (use electric heat, ducted heater or ground thaw). Keep protection in place minimum 24 hours after cessation of heating to provide gradual cool-down.

18. When air temperature is above 85 degrees, provide mist, shading, windscreens and other protection as required for 12 hours after placing.

19. Concrete being placed shall be protected from rain. If rain falls on concrete before it has set, or within 3 hours of placement in any event, contractor shall bear cost of testing to prove concrete is unaffected, and shall remove and replace affected concrete to the satisfaction of the engineer.

20. Wet cure (poly and burlap or proprietary blankets kept moist daily) for a minimum of 7 days; sides of footings may be buried after 24 hours. Add one day of cure for flyash in excess of 15 percent or GGBFS in excess of 10 percent of cementitious. Contractor is responsible for staining caused by burlap in visible areas. Spray-on curing compounds shall not be used as a substitute for wet curing without written permission of the SER except as follows. Liquid-containing structures must use a wet cure on all surfaces. Spray-on curing compounds may be substituted for wet curing in areas of non-liquid-holding structures that are not visible in the final condition and in liquid holding structures in winter conditions where water curing may be hazardous or difficult.

When spray-on curing compounds are used, they should be applied in two layers perpendicular to each other and according to manufacturer’s instructions.

21. Cementitious grout shall be non-shrink and non-metallic grout. Place according to manufacturer’s recommendations and trim neatly where visible.

22. Coordinate with other trades for sleeves, conduit, electrical grounding wires, inserts, underground utilities, and other items to be embedded into concrete and verify that they are properly installed and supported before casting concrete. Holes through slab or wall shall leave minimum 1 inch clear to reinforcing;

shift reinforcing as required. Placement of such items shall be coordinated with reinforcing placement where they would otherwise displace each other. For instance, in areas with a single mat of reinforcing, east-west conduit should be placed with east-west reinforcing and north-south conduit is placed with north-south reinforcing.

23. Embedments shall not significantly impair the strength of the structure and shall not reduce fire protection. In no case shall embedments violate the required concrete cover. Conduit and pipes, with their fittings, embedded in concrete shall not be larger in outside dimension than 1/3 the overall thickness of slab, wall, or beam in which they are embedded and shall not be spaced closer than three diameters on center. Conduit and pipes placed within 2 feet below bottom of slabs and footings shall not be spaced closer than three diameters on center and shall be encased in CLSM or concrete vibrated to flow around conduit.

24. No uncoated aluminum items shall be embedded in any concrete. All aluminum surfaces in direct contact with concrete shall receive one coat of 8-12 mil dry film thickness bitumastic.

25. Unless shown on drawings, concrete shall be placed without construction joints except where specifically shown on shop drawings approved by the engineer. The contractor shall submit shop drawings showing additional or alternate construction joint locations to the engineer for approval.

26. Bevel all exposed corners of concrete 3/4"x3/4".

27. Verify size and location of all equipment bases and housekeeping pads.

28. All cast-in-place concrete floors on grade shall be provided with a min. 1/8" per FT slope to floor drains unless noted otherwise. All interior slabs on grade shall be placed over 10 MIL vapor retarder meeting ASTM E1745 class A, with joints welded or lapped and sealed according to manufacturer’s recommendations. Vapor retarder shall permit less than 0.01 perm after conditioning. All damage and penetrations shall be sealed according to manufacturer’s recommendations.

JOINTS IN CONCRETE STRUCTURES

1. Because of the effects of concrete consolidation, workmanship, detailing, cure, temperature, aggregate size, and other factors; Contractor is responsible for cracking in slabs and walls of structures, and shall repair any leaking cracks by sealing, injecting, or otherwise filling them. Where sealing is judged necessary by either Contractor or Engineer, Contractor shall submit material and description of sealing to be used for review by Engineer. Note that crystalline waterproofing will heal tight cracks (less than approximately 1/64”) over time in warm temperatures, but wide cracks or leak tests attempted in cold temperatures will require additional measures. Any wall which is or may be subject to external groundwater is considered liquid holding.

2. Contractor is encouraged to use well-graded aggregate larger than ¾”; fiber reinforcing; shrinkage reducing admixtures; crystalline waterproofing;

extended moist cure; and other means to reduce shrinkage. If used, crystalline waterproofing shall be used at the manufacturer’s recommended dosage.

3. Concrete slabs on grade in structures:

a. Contraction joint spacing in non-liquid-holding steel-reinforced slabs on grade (building floors) shall be spaced at a maximum of 24 x Thickness, but not more than 15 feet, in each direction. Contraction joint spacing in fiber-reinforced slabs on grade shall be spaced at a maximum of 30 x Thickness, but not more than 18 feet, in each direction. A slab of dimension 20 feet or less does not need to be divided by a contraction joint in that direction except as required by aspect ratio. The aspect ratio of any panel shall not exceed 1.50. Unless noted on drawings, Contractor shall submit proposed contraction joint spacing for review. Where slab is reinforced with bars #4 or greater, cut or interrupt every other bar at each contraction joint. Joint depth shall be slab thickness / 4, with a minimum of 1”. If sawcut, joints shall be cut as soon as it is possible to do so without raveling the concrete, but no later than 12 hours after placement.

b. Construction joints in building floor slabs on grade shall provide for shear transfer across the joint, using plate dowels such as Diamond dowels.

Round or square dowel rods shall not be used. Reinforcing bars may be used where shown on drawings, e.g. at stoop or apron joints. Plate dowels shall be sized per manufacturer’s recommendations and spaced at manufacturer’s recommended spacing (18 inches max for wheeled traffic on slab, 24 inches max otherwise). If subject to de-icing salt, plate dowels shall be galvanized or epoxy coated.

WATERSTOPS

1. Waterstops in new construction shall be 6-inch PVC, center bulb, ribbed, unless specifically noted otherwise.

2. At splices, miter all intersecting connections at 45 degrees and use a manufacturer approved heating iron to make full contact butt joints.

3. For construction joints at hardened concrete, hydrophilic waterstops may be proposed by the contractor in lieu of adhered split-T PVC waterstop.

Such material shall be selected considering water head to be resisted, concrete cover in all directions, reinforcing present through the joint, and whether waterstop is continually immersed. Contractor’s proposal shall include waterstop information and contact information for a technical representative of the waterstop supplier along with the representative’s written recommendation of the type of waterstop to be used. Hydrophilic waterstop shall not be used unless this process is followed.

REINFORCING STEEL

1. All concrete is reinforced concrete unless specifically called out as unreinforced. Reinforce all concrete not otherwise shown with same steel as in similar sections or areas. Any details not shown shall be detailed per ACI 315 and meet requirements of ACI 318, current editions.

2. All reinforcing steel shall conform to the requirements of ASTM A615 grade 60 steel. Reinforcing steel shall not be welded without authorization of the SER, and if welded shall be A706 grade 60 steel. Reinforcing to be welded shall only be welded to structural steel, not other reinforcing, unless specifically noted on the drawings. Welded plain wire fabric shall be supplied in sheets, not rolls, and conform to the requirements of ASTM A185.

3. Clear minimum cover of concrete over reinforcing steel shall be as follows unless specifically noted otherwise:

• 3" Concrete placed against earth

• 2" All other concrete

4. All reinforcing shall be tied to crossing reinforcing on at least every other bar (every bar at perimeter), and sufficiently to resist displacement from workers and placement of concrete.

5. All footing dowels shall be accurately positioned and wired in place before casting footing concrete. Where not noted, provide and install hooked dowels of same size and spacing as vertical reinforcement in all columns and walls. Position all anchor bolts with templates.

6. Bar lap lengths in concrete and 90 degree end hooks shall be in accordance with the bar lap table unless noted otherwise. This table lists class ‘B’ laps. For epoxy coated reinforcing steel, increase lap length by 50% with c-c bar spacing < 6db and cover to center of bar <3db, otherwise increase by 20%. For masonry reinforcing, use fc’ = 3000 psi values.

7. Bars marked continuous, corner bars, and all vertical steel shall be lapped in accordance with table above at splices and embedments, unless shown otherwise. Splice top bars near midspan and splice bottom bars over supports, unless noted otherwise.

8. Slabs on ground with a single mat of reinforcing may be reinforced with FRP bars such as Gator Bar or similar, substituted one for one (same bar size and spacing) as the steel reinforcing called for on the drawings. FRP bar may not be substituted for steel reinforcing for any other purpose without written permission from the SER.

9. Bar support accessories shall be as specified in latest edition of the ACI detailing handbook and the concrete reinforcing steel institute design handbook. Maximum accessory spacing shall be 4'-0" on center, and all accessories on exposed surfaces shall have plastic coated ends. Chairs shall be supported on sand plates as required to keep from sinking into subgrade. WWF shall be supported by continuous bolsters or bars on chairs sufficiently close to prevent sheets from sagging appreciably during concrete placement. Support rebar used at contractor’s option shall be extra bars supplied by contractor, not taken from design reinforcing.

10. Where potentially exposed to de-icing salts; stoop, apron, sidewalk and floor reinforcing shall be epoxy coated.

CONCRETE REPAIR

1. Locate and remove areas of loose, delaminated, or damaged concrete. Saw cut outside perimeter of damaged areas to a minimum depth of approximately 3/4 inch; do not cut reinforcing. Tally areas removed for payment. Sandblast area to be patched and blow clean. Protect surroundings and workers from dust and hazards associated with this work.

2. Where half or more of the perimeter of reinforcing bar is exposed, bond between reinforcing bar and surrounding concrete is broken, or reinforcing bar is corroded, remove concrete from entire perimeter of bar to provide minimum 3/4 inch clearance behind bar. Clean and coat exposed surface of bar with bonding agent (Sika Armatec 110, Sonoprep, or Euclid Corr-Bond).

3. Dampen patch area and apply mortar scrub coat, keeping moist until patch is applied.

4. Patch with polymer-modified cementitious patching mortar (Dayton Superior HD-50, Euclid Verti-coat, Master Builders Emaco

R320, Sikatop 121, or Sonopatch 100). Cure according to manufacturer’s recommendations.

CONCRETE SEALING

1. Shotblast areas to be sealed.

2. Repaint parking lines, handicap symbols and other paint to match existing, using paint acceptable to the owner.

3. Apply 100 percent solids sealer according to…
