Do cost estimation for the designed parking space as shown in the diagrams (you can use the boq estimates in your country , convert them to pounds)
design description
Researches on multi-storey car parks show that water that cannot be removed quickly damages the building structurally. Chemically, water containing chloride ions causes great damage to the building surface. In order for the buildings to last longer, great importance should be given to the drainage system.
Drainage
A well-designed drainage system is required in order to quickly remove the water coming from outside without accumulating on the surface. In the UK, drainage is designed to BS 83019.1 and BS EN 120569.2, and in other countries local standards will apply. In the UK the drainage is designed to BS 83019.1 and BS EN 120569.2 and in other countries local standards will apply.
The top floor is the area most exposed to water, so local precipitation statistics were taken into account when designing the drainage system. It is normal for puddles to form in storm conditions and should be removed as soon as possible. Water comes to the intermediate floors partially from the side facades and as a result of the transportation of vehicles. Since the car park is warmer than outside, the ice on the vehicle melts and causes puddles, a vehicle can carry an average of 2 litters of water. These waters must be transmitted to the drainage system as soon as possible.
Figure 1(NW3 Weather – Rain Detail, n.d.-b)
33.3 mm/h X 48.6 m X 125 m = 0.056 m^3 / second
0.056 (m^3/second) / 1.5 = 0.085 m^3/second
When the London rain data is examined, it is seen that the maximum rain in one hour is 33.3 mm. In order to calculate using this data, the surface area of the car park is found and then multiplied by the maximum rain rate. The result is 0.056 M^3/second. When the safety factor is taken as 1.5, it is seen that 0.085 M^3/second or 85 litter/second of rain accumulates on the top floor. In the designed drainage system, this amount will be removed from the roof as soon as possible by pipes.
While the drainage system was designed for the upper floor, it was planned to put stainless steel drainage channels between the car parks. Pipes that provide water transfer will be used in one of every 2 columns to ensure water transmission to the lower floor. It is planned to use 3 rows of drain channels for typical floor floors, 2 channels of 72 meters will be used for long rows and 21.6 meters of channels will be used for short rows. Three 72-meter-long drainage channels, one 28.8-meter-long drainage channel and 2 14.4-meter-long drainage channels will be used on the ground floor. As a result, 266.6(ground floor) + 3 (floor) X 165.8 (typical floor) = 763.4 meters drainage channel will be used for the multi-storey car park planned for 3 floors.
For the parking spaces on the sides, a deck will be placed in the middle of both columns to provide water drainage. As a result, each floor will have 24 decks and the multi-storey car park will have a total of 24 X 3 = 72 decks.
Ramps
Since the ramps are inclined, they are a way for the water to flow to the lower floors. In order to prevent this, drainage channels should be placed at the beginning and end parts of the ramps, otherwise the water from the upper floors will go towards the lower floors. In addition, the ramps should remain as dry as possible because access to the lower / upper floors is provided by these roads. In a possible wet/freezing situation, the risk of accidents arises. Therefore, the ramps should be cut with drainage channels and water drainage should be provided.
The drainage lengths to be placed at the start and end areas of the ramps are designed to be 3.65 meters, and since there are 6 ramps in total, there should be 6 (ramps) X 2 (start – end) X 3.65 = 48.8 meters drainage channel.
Pedestrian areas
When designing the drainage system, it should be designed in such a way that it prevents the water coming from outside to go to the stairs and elevator shaft. It should be designed in such a way that pedestrians will not trip or fall during this design.
Piping systems
Pipes are the most important transmission parts of the drainage system, during this design they must be positioned so that they are not damaged. Since it is not possible for downpipes to pass through the column, they should be placed on the protective side of the column, thus preventing possible accidents.
The water discharged from the decks and the drainage channel is conveyed to the lower floors by means of pipes, following the nearest branch. The distance required to reach the nearest columns from the decks was found by a simple geometric calculation of 4.2 meters. Since there are 24 decks on each floor, 4.2 X 24 X 3 = 302 meters of pipe is not required. In addition, the water in the drainage channels on each floor should be directed to the nearest column and the distance required for this is 4.2 meters. Pipe should be used to discharge the water coming from the 26 drainage channels on each floor and its end. It is 302 meters. The amount of pipe to be used for the upper floors is 604 meters.
Interceptors
Oil and oil are sometimes mixed into surface waters as a result of leaks from vehicles. After this mixture is collected through drainage channels, oil and petroleum must be removed before it is given to the sewer system. For this, the stoppers must be located outside the car park or in an easy-to-maintain location within the building.

A pumping rate of 0.08 m3/s lowers the steady-state water

Problem 9.4. Before constructing a building, it is necessary
to lower the water table (standing at 35 m above the bedrock
prior to any pumping) in the area shown in the figure below
to allow for excavation.
The building foundation is circular with a diameter of 40 m. If
a pumping rate of 0.08 m3/s lowers the steady-state water
table by the required 22 m (enabling the excavation to take

pumping well is approximately 500 m.

Discuss the importance of curing concrete and the importance of the availability of water.

Question 1. Describe the process of setting and strength gain in portland cement systems. Describe which hydrates are formed and the rate of temperatures they are formed at. Define initial, final, flash, and false set.
Question 2. Discuss the importance of curing concrete and the importance of the availability of water.
Question 3. Use the following information to complete the concrete mixture design.
The following materials are available for a concrete mixture design: ASTM C 150 Type I/II Cement Relative density of 3.15
Coarse Aggregate: well-graded ¾ in. maximum-size aggregate (MSA), crushed limestone, angular Oven-dry specific gravity: 2.45
Absorption: 0.80%
Oven-dry rodded bulk density: 97 lb/ft3
Moisture content of coarse stockpile: 0.63%
Fine Aggregate: well-graded natural sand Oven-dry specific gravity: 2.64
Absorption: 1.4%
Moisture content of fine stockpile: 2.8%
Fineness Modulus: 3.00
An air entraining admixture will provide enough air for the design mixture at a dosage rate of 3 oz/ft3, if the system needs to be air entrained. Concrete is required for 6 in thick concrete sidewalk in NJ. A specified compressive strength, f’c , of 3300 psi is required at 28 days using an ASTM C 150 Type I portland cement. The design calls for a minimum of 1.5 in. of concrete cover over the reinforcing steel. The minimum distance between reinforcing bars is 6 in. A slump of 4 inches should be the target. The sidewalk is located in a freezing and thawing climate with limited exposure to moisture (mild exposure). No exposure to sulfates is expected. No statistical data on previous mixes are available. Determine:
a. The theoretical mixture proportions of all concrete constituents (fine aggregate, coarse aggregate, water, cement, chemical admixtures) based on 1 yd3 of concrete on an oven dry basis for aggregates. b. The as-batched mixture proportions based on the moisture contents provided in the materials available section. c. How much of each material would be required to make a 35 ft long by 5 ft wide section of sidewalk from the concrete mixture described above?
Question 4
You are performing mechanical properties tests on some concrete specimens. The compression and splitting tensile strength tests were done on cylinders measuring 4 in. diameter and 8 in. height. The flexural strength test was done on a prism measuring 14 in. length, 4 in. deep by 4 in. wide. The compressive strength cylinder broke at a load of 115,450 lbs. The splitting tensile strength specimen broke at a load of 28,300 lbs. The flexural strength specimen broke at a load of 4300 lbs. Assume the concrete had a unit weight of 140 lb/ft3
.
a) Calculate the compressive strength of the concrete mixture. b) Estimate the modulus of elasticity of the concrete mixture
c) Calculate the splitting tensile strength of the concrete mixture. d) Calculate the modulus of rupture of the concrete mixture.
