2.9 - Temperature Limits for Cold Weather Concrete

Provide concrete having a minimum temperature of 50 degrees F and a maximum temperature of 90 degrees F at the time of placing. The temperature of the mixing water shall not exceed 140 degrees F. If aggregates are heated, heat uniformly with steam or water coil. Aggregate temperature shall not exceed 95 degrees F. Aggregate water mix temperature shall not exceed 80 degrees F. Do not use materials containing frost or icy lumps.

2.10 - Temperature Limits for Hot Weather Concrete

Provide concrete having a maximum temperature of 90 degrees F at time of placing. If the ambient temperature is above 90 degrees F, the forms, reinforcing steel, steel beam flanges, and other surfaces which will come in contact with the mix shall be cooled to below 90 degrees F by means of a water spray or other approved methods. Water reducing admixtures shall be used so the maximum amount of water or slump is not exceeded. The mixing of the concrete and the time between mixing and placing shall be kept to a minimum. Chipped or crushed ice may be substituted for a portion of the mixing water on a pound-for-pound basis. If ice is used, all ice shall be entirely melted at the completion of the mixing period.

2. Place concrete within a maximum of 1-1/2 hours or before the drum has revolved 300 revolutions, whichever comes first after the introduction of cement into the batch. In hot weather or due to other contributing factors, a time less than 1-1/2 hours may be required by the CO.

3. Time interval between placement of batches shall not exceed 30 minutes.

(b) Hand Mixed:

Hand mixing will not be allowed.

2.12 - Mix Adjustments

(a) Water: Water may be added once for purposes of acquiring minimum slump, provided the specified water-cement ratio is not exceeded. For all project mixed concrete, water shall not be added later than 15 minutes from start of mixing. For transit-mixed or agitated concrete, such water may be added upon arrival at the job site. Adding water beyond these conditions constitutes re-tempering which will not be allowed. When water is added, an additional 20 revolutions at mixing speed is required.

(b) Admixtures: Air-entraining admixtures shall not be added after the start of mixing.

PART 3 - EXECUTION

3.1 - Construction

(a) Excavation: Excavation shall be made to the required dimensions to permit the installation and bracing of the forms. The foundation shall be compacted to a firm even surface. All soft, yielding material shall be removed and replaced with acceptable material.

(b) Forms: Forms shall meet the requirements of Specification 03100 - Concrete Formwork.

(c) Contraction Joints: Contraction joints shall meet the requirements of Specification 03251 – Expansion and Contraction Joints.

(d) Expansion Joints: Expansion joints shall meet the requirements of Specification 03251 – Expansion and Contraction Joints.

(e) Mixing and Placing: The concrete shall be struck off to the cross section SHOWN ON THE DRAWINGS, after which it shall be finished to a smooth and even surface.

(f) Reinforcement: All reinforcing steel shall meet the requirements of Specification 03201 – Concrete Reinforcement.

(g) Placement: Concrete shall be discharged into the forms within 1-1/2 hours after the introduction of the cement to the aggregate. Re-tempering concrete shall not be permitted. The cement shall be added to the mixer at the jobsite whenever this condition cannot be met.

(h) Temperature: Concrete shall not be mixed or placed when the daily minimum atmospheric temperature is, or is expected to be, less than 40 degrees F unless adequate provisions are made to protect the concrete. No concrete shall be placed when the concrete temperature reaches 90 degrees F.

(i) Consolidation: Concrete shall be placed to avoid segregation. High-frequency internal vibrators shall be used for consolidating concrete in the forms. Vibrators shall be operated to produce concrete free of voids, but shall not be held so long in one place as to result in segregation or formation of laitance on the surface.

(j) Handling: The use of aluminum pipe, conduit, or troughs for transporting concrete will not be permitted. When concrete is pumped, sampling shall be from the discharge stream at the point of placement.

(k) Finishing: For the purpose of matching adjacent concrete finishes or for other reasons, the CO may permit other methods of finishing than those specified. No plastering will be permitted.

(l) Concrete Placement: Notify the CO a minimum of 24 hours prior to placement.

Place concrete in the forms as near final position as practical in a manner which will prevent segregation or loss of materials.

Place concrete in maximum 18" horizontal layers.

Immediately after placing, thoroughly compact concrete with mechanical vibrators. Provide minimum of two vibrators. Provide minimum of two power sources unless commercial power is available at site. Hand tamping, when permitted, will be approved in writing by the CO.

Place each concrete section in a continuous operation, such as slab, footing, columns.

Do not drop concrete freely more than 4 feet.

Do not place concrete in water or allow water to rise over freshly placed concrete until a set is sufficient to prevent damage.

(m) Backfilling: After the concrete has set sufficiently, it shall be backfilled to the required elevation with selected material placed in horizontal layers, not over 6 inches (loose measure) in depth, to the level of the original ground surface. Backfill shall be readily compactable material free of frozen lumps, chunks of highly plastic clay, or other objectionable material. Rocks larger than 3 inches in diameter shall not be used within 1 foot of the structure.

(n) Protection from Rainfall: Protect flat work during rainy periods with adequate waterproof covering. Support covering so that finishing may be performed and initial set obtained without damage. Dragging of tarpaulins or other covering across unset concrete will not be permitted.

(o) Curing: Commence curing and protection of concrete immediately after completion of the finishing. Cure Type I and Type II cement for 7 days continuously. The work shall be moistened and kept moist during this time, or curing shall be accomplished by the use of membrane-forming curing compound.

(p) Cold Weather Concreting and Curing: When the descending air temperature at the project falls below 40 degrees F the Contractor shall cease placing concrete unless the procedures described below are followed. Normal concreting operations may resume when the ascending temperature at the site exceeds 40 degrees F.

END OF SPECIFICATION 03301

Questions and answers:

1. Where is the site location This is in the vicinity of Cave Creek. In our Recreation area called Needle Rock along the Verde River. Use Google Maps for Needle Rock and you will find it.

1. What vegetation removal if any is required? Are the trees and bushes in the area of work considered the debris?

Only vegetation removal for debris and anything growing in the alignment of the pipe rail when it is reinstalled.

1. Wil there need to be any site grading? More specifically where the new access area is going to be and where the rail near the entrance is being removed?

Site grading only to the affect to not leave any holes or mounds created during the removal and installation process.

1. Will the parking lot be closed during construction time frame of project?

The parking lot will be closed during the project but will hopefully only take a week for each phase so it can be open on weekends.

1. Is there any fire or hot work permits needed for any onsite welding or cutting?

The tonto fire plan requires there to be a fire “kit” and water since you are welding. I will have to confirm if we are in fire restrictions when the project starts too.

1. When dealing with any potential water encounters during drilling of post footings will we be allowed to dewater as we pour concrete? Allowing for it to push its self out?

Yes you can dewater if necessary.

1. Is there any access to a water source on or near site we can use?

Water from the river is not able to be used for construction purposes.

1. In regards to solicitation number: 12818019Q0003 is the only scope of work asking to be performed stated on pages 2 (tasks1,2,and3) and page 3 (section a and b) which is demolition of pipe rail and pipe rail fence installation? Because on page 14 there is mention of Removal of toilet. Just want to make sure that the RFQ is only for the pipe rail and beach rail.

Only the items listed (see chart below) are to be bid on, there is not a toilet to be removed however, the removal of any debris that is in the way would be included.

1. It also states remove footings of existing post. Do you have a soils report for this project? I didn’t see one.

Riverbed. Lots of sand. You will need sonotubes to form the new footings. Old ones will just come right out.
