MANHOURS PER SQUARE FOOT Footing form manhours are based on using 2-inch by 12-inch material pro p erly braced and anchored. If footing height is to be greater than one foot, add t we n t y- f i v e percent to manhours for each additional foot or fra c t i o n . Assume heavy mat forms to be made of 2-inch material at least 3 feet high. If

When using this table, you will see that 8" x 8" x 16" block takes "one person" (skilled labor) 160 man-hours to lay 1,000 square feet of CMUs. If you were to break this labor down into how many CMUs laid in an 8-hour period, it would be calculated as follows: 1000 sf of wall area= 1,125 CMU . 160 man-hours ÷ 8 hour days = 20 duration days

Concrete Forms and Finishing: $1.50 $2.00 per square foot. Labor is the biggest cost for concrete forms. Setting up concrete forms and finishing concrete is backbreaking work. More about concrete forming supplies. Reinforcement: $0.15 $0.30 per square foot. Reinforcement is required because all concrete cracks, so if you want your cracks to

cubic yards moved. That’s now the accepted procedure for most projects, from single-family homes to roads and commercial jobs. Some projects are still bid lump sum, but those are the exceptions. It’s common for the actual amount of dirt moved to be more or less than expected, so the best way to protect your business is to bid by the cubic yard.

Lets say for 10m3, the hydraulic excavator is taking 0.04125 day. Then its capacity considered is ((1×10)/0.04125) = 242.4242 m 3 / day. That means, a hydraulic excavator can excavate 242.4242 m 3 of soil in one day. Its cost per day including driver and fuel is Rs. 5000. Then the cost of 10m 3 of excavation can be calculated as:

When determining the cubic yards, take the acres to be dredged and multiply 1,600 cubic yards per foot of material depth. So for example, if you have a 10-acre lake and the depth of material to be dredged is five feet, your formula will look like this: 10 x 5 x 1,600 = 80,000 cubic yards.

Concrete Delivery $123.50 to $138.27 per cubic yard (3,000 psi 3/4" crushed stone) Price estimate include labor. Estimate includes delivery of concrete material (3,000 psi, 3/4" stone). Cost excludes long-distance deliveries or reinforcing materials. Reported by: ProMatcher Research Team See the Paterson Concrete Cost Report

Dec 17, 2018· Accessibility and hand demolition. The location of the removal and the type of concrete play a key role in labor costs, says Henry Fuapau of 4Sons Concrete.When a concrete removal crew is not able to use its hydraulic and machine-operated equipment to quickly break up the concrete, the contractors have to do it by hand using sledgehammers, pry bars, and other handheld tools.

Unreinforced concrete is easier to remove, as well as lighter and easier to dispose of. 1.5-inches of concrete weighs roughly 18 pounds per square foot, and costs roughly $400 to remove using jack hammers and a hydraulic lift.

We will test the soil and bore through the ground to analyze the soil to determine if there are any rock particles and then come up with an estimate of what the total costs will be to remove the rock. Depending on the rock type and other conditions underneath the surface, rock excavation jobs can cost between $5 to $35 per cubic yard.

rates of more than 1,100 cubic y a r ds of unre i n f o r ced concrete per d a y, with 50 to 250 cubic yards per day being typical for mid-s i z e d Whether mounted on a backhoe-loader or an excavator, hydraulic hammers combine mobility and impact power to demolish concrete quickly and efficiently. Breaking up is hard to do By John A. Koski

Excavating a cubic meter of dirt for a footing by hand is a serious job. For ordinary soil, that is, soil that isn’t packed hard or full of roots, rocks, or other debris, the 3 to 4 thousand pounds of soil can be removed by a single worker in a fe...

If the local wage rate including burden and fringe benefits is LE30 per hour, the unit labor cost becomes LE16.50 per m2. If the wage rate is LE20 per hour, the unit labor cost becomes LE11 per m2. In addition, productivity performance between projects can also be easily compared if contractors keep cost accounting records in man-hours.

To determine the cost to pour concrete slab, use the following tips: Amount. Calculate the volume of concrete you need in cubic yards. The formula for cubic yards is this: Multiply the length (10 ft.) by the width (10 ft.) by the depth (.35 ft., or 4 in.) and divide it by 27 (the number of cubic feet in a cubic yard).

Flowable fill is defined by the American Concrete Institute (ACI) as a self-compacting cementitious material that is in a flowable state at placement and has a compressive strength of 8.3 MPa (1,200 lb/in 2) or less at 28 days. Most current applications for flowable fill involve unconfined compressive strengths of 2.1 MPa (300 lb/in 3) or less.

The average cement truck carries around 6 cubic metres of concrete. Partial loads may be subject to a fee per empty cubic metre. As an alternative, ready-mix trailers can sometimes be hired. These carry up to 1 and three quarter cubic metres, can be attached to a pick-up truck and work out cheaper.

Volume is: 52 sq. ft. x 12.33 feet = 641.33 cu. ft. Or expressed as Cubic Yards is 641 / 27 = 23.7 Yards3 Where this method has only applied the angle of repose in two dimensions, the SAE Standard Formula applies it in three. Therefore experience tells us that the actual rated capacity of this bucket will be closer to: 23 or 23.25 Yd3 6

For example, if a 4 cubic yard piece of hard rock (20,000 psi or greater) needs to be broken in half, a 7,500 ft·lb or larger breaker is required. If a 2 cubic yard piece of limestone (20,000 psi or less) needs to be broken in half, a 3,000-5,000 ft·lb breaker is required. Trenching
