Having been in the business many years ago, once the slab is poured, no more than 3 weeks depending upon options. Also depends upon where the raw bauxite is imported from…you guessed it, Russia.

Really would like to know your contractor. I am having same problem. Our contractor took 3 months just to apply for a permit.

27 days after concrete is placed it is at its designed specification. Usually 350 PSF.

Yes my next door neighbor had a pool put in and she has been waiting about 5 months for the cage to finish it off. They can’t get all the materials. Contractor has tried several sources, including the Tampa area. I think if pool people aren’t working with T&D, they are all having problems getting the cages up timely. T&D places the order for all materials when you sign the contract, then stores them in a warehouse for construction 6 months later. T&D may have exhausted the local supplies so other contractors are having a tough time getting materials….especially cages.

Sorry but you're being lied to
give him a dead line, which should have been in the contract to begin with.

Hurricane Ian has also impacted this area as contractors have either gone to the coast or contractors have come here and depleted the supplies.. always happens after a major hurricane

If you want to enforce a contract deadline, you should include the legal phrase, "time is of the essence". Otherwise, a contract completion date is not enforceable.

IMHO your quoted compressive strength of 350 psi is off by a factor of 10 for mid range concrete mixes as defined by bags of Portland cement per cubic yard of concrete. From 50 years ago construction and engineering school, basement non load bearing slabs were 2000 psi and highway paving was 5000 psi.

Generally accepted curing rules are that concrete reaches 70 % of its ultimate strength in 7 days and that normal construction activities can continue. In TV you will see that wall block works starts in 2 days typically. The graphs typically show 10% strength gain per day for 7 days in basically a straight line. After that the strength increase rate generally slows down. 28 day strength is typically stated as 90% of ultimate strength. Theoretically concrete continues to gain strength "forever" at a continually decreasing rate but gains less than 10% additional past 28 days.

There is no need to avoid doing some work on the birdcage slab for more than 3 days to 7 days maximum. Generally shrinkage cracking control cuts are made the next day. Starting to drill the holes for attaching the frame can start soon there after. Using machinery to move large loads should wait for 7 days anyway.

The other poster said 350 PSF, which is equal to 2.43 PSI.

An experienced crew would have it built with screens installed in less than a day.

3 Months total concrete permits the whole thing 20 x 25 ft

can you please state the name of the company?

With the supply chain..totally messed up..thanks to nonsense.. patience is a blessing..food, fuel, building products etc.. are controlled right now.

Then he was off by another 144 times. 3500 /2.43= 1,440

Check the internet: "Compressive strength is tested by breaking cylindrical concrete specimens in a special machine designed to measure this type of strength. It is measured in pounds per square inch (psi). Testing is done according to the ASTM (American Society for Testing & Materials) standard C39.

Compressive strength is important as it is the main criteria used to determine whether a given concrete mixture will meet the needs of a specific job.

Concrete psi
Pounds per square inch (psi) measures the compressive strength of concrete. A higher psi means a given concrete mixture is stronger, so it is usually more expensive. But these stronger concretes are also more durable, meaning they last longer.

The ideal concrete psi for a given project depends on various factors, but the bare minimum for any project usually starts around 2,500 to 3,000 psi. Each concrete structure has a normally acceptable psi range.

Concrete footings and slabs on grade typically require a concrete of 3,500 to 4,000 psi. Suspended slabs, beams, and girders (as often found in bridges) require 3,500 to 5,000 psi. Traditional concrete walls and columns tend to range from 3,000 to 5,000 psi, while 4,000 to 5,000 psi is needed for pavement. Concrete structures in colder climates require a higher psi in order to withstand more freeze/thaw cycles."

I stand by my estimate that the slab for a birdcage will be 3500 psi design or lower and can be worked on for birdcage supports in less than 7 days.

Only if supplies are available.. have you checked where stuff comes from lately?
