Civil Engineering
Civil Engineering is a profession of designing and executing structural works that serve the general public, like houses, buildings, roads, etc. A Civil Engineer is an engineer trained in the design and construction of public works, such as bridges or dams, and other large facilities.

How expensive are groynes to build?
The cost of building groynes can vary significantly depending on factors such as location, materials, and design. On average, constructing a single groyne can range from tens of thousands to several hundred thousand dollars. The total expense can also increase based on the length and complexity of the structure, as well as environmental considerations and permitting costs. Overall, it's essential to conduct a detailed feasibility study to obtain a more accurate estimate for specific projects.
How much force can an 8 year old push down with?
It really depends on the 8-year-old. You'd need to consider the kid's weight, level of physical activity, muscle mass, body fat percentage, extracurricular activities (sports can affect muscles), and many other factors.
Why limit state method is now a days used for the design of RCC structures?
because by these method all loads are considered ,and the structure is designed to undergo these loads
What are prefabricated rcc element?
all elements like RCC slab, beam, column, wall and staircase can be a prefabricated RCC element..prestressed prefabricated RCC members also available in the market.
What is the definition of site investigation?
Site investigation derives from Geotechnical investigations which discuss how the properties are of natural land before being built.
What is the longest bridge in New Zealand?
The longest bridge in New Zealand is the State Highway 1 bridge over the Rakaia River, around 50km (30mi) south-west of Christchurch. The bridge is a two-laned beam bridge, and from end to end measures 1757 metres (5765 ft).
There are, of course, many iron bridges all around the world but one which is sufficiently famous to be commonly referred to as "The Iron Bridge" is across the River Severn in Shropshire, England.
The part of the river which it spans is named Ironbridge Gorge and the town of Ironbridge is a major tourist attraction which promotes itself as "The birthplace of the Industrial Revolution."
It was the first arch bridge in the world to be constructed from cast iron and it's construction was one of the landmark events, if not exactly the birthplace, of The Industrial Revolution.
It was designed byThomas Farnolls Pritchard who was greatly assisted by Abraham Darby who had developed the process of manufacturing cast iron cheaply.
Where could one find more information on aqueducts?
There is a Wikipedia page on aqueducts, which may be good for a start. Alternatively one could go to the local library and inquire about books they might have on the topic.
Estimating Project Costs
Estimating project cost means developing an estimate for the monetary resources needed to complete the project work; that is, activities. These estimates are based on the information available at a given time. The estimates in the beginning are less accurate; for example, their accuracy may be only as good as + or - 50 percent. For example, if you say the cost will be $50,000, it could be anywhere between $25,000 and $75,000. As the project moves along and more information becomes available, the cost estimates can be improved to get better estimates.
Determining Project Budget
Determining the project budget is the process of aggregating the cost estimates for all project activities and assigning a timeline to them. Cost aggregation is the technique used to calculate the cost of a whole by summing up the costs of the parts of which the whole is made. You can use the bottom-up estimation technique to aggregate the costs of all the components and activities to calculate the total cost of the project. The timeline assigned to this cost will be important to reconcile the expenditure with the funding limits. The reconciliation may require rescheduling some activities.
Controlling cost means monitoring and controlling updates and changes to costs, budget, and the cost baseline of the project. Monitoring and controlling costs has two dimensions to it: expenditure of project funds and the work performed as a result of those expenditures. One major aspect of cost monitoring and controlling is to determine the relationship between the expenditures and the accomplishments. The cost performance depends on this relationship. The other main aspect is to control the changes to the approved cost performance baseline.
Trivia:
Like any other change, change in cost and budget must also be processed through the integrated change control process and should only be implemented after its approval.
To be more specific, monitoring and controlling the project cost includes the following tasks:
• Influence the factors that can create changes to the approved cost baseline.
• Monitor the following:
o Work performed against the funds expended
o Variance of cost performance from the approved baseline • Prevent unapproved changes from creeping into cost reports and expenditures.
• Act to keep cost overruns within the planned acceptable limits.
• Ensure the following:
o Change requests are dealt with in a timely fashion and managed as they occur.
o Expenditures do not exceed the approved budget by period or by total amount. Any change to the budget must be approved before implementation. • Communicate with the appropriate stakeholders about the cost associated with the approved changes.

Wire rope was invented by a German named Wilhelm Albert in the years between 1831 and 1834
The main asphalt paving product is hot mix asphalt, in which asphalt cement is used to bind a mixture of stone, sand, and gravel.
Assuming you mean a concrete foundation- after concrete is mixed, it undergoes a chemical change. It does not "dry"- it "cures"- and becomes harder. The process takes place over a period of days or weeks- gradually getting harder and stronger.Until it has cured- or hardened- enough, you cannot place heavy weights on it, or the fresh concrete will break. It usually reaches adequate cure within a few days, andnear max cure at 28 days.
If you are talking about the balsa wood then you just need to just the wood into necessary parts of the suspension bridge.Download pictures of suspension bridge and then carve out the lower part with roads and put holes on the sides of the flat wood for lower part.Then make the towers to which the cables are attached.You can either design yours or see the picture and carve or cut them out.Let the shape be simple as you want it to be easily and quickly done.Drill holes in the tower at the top on the sides so to attach the cables.Make sure that the pillars or towers are much larger in length as you will see it in the picture you shall download(** MAKE ONLY ONE PILLAR JUST TO SYMBOLIZE).So let the towers be like that.Get the cables either of plastic strings or some soft metal strings and let them pass through holes and tie a knot at the ends to fix them there.Making the bridge out of the balsa wood shall be a not more than 8 hours of consistent working.So Just make sure what you are making and draw out what you are going to make how it is going to look. Using a different material might reduce time like thermocol sheets but as they are fragile so it can be difficult to do the job with them.

What is the volume of 50 kg cement in cubic -metre?
as unit weight of cement varies from 830kg/cu.m-1650kg/cu.m
volume of cement of 50 kg. varies 0.060241cu.m to 0.030303cu.m
if the cement is port-land cement unit weight would be 1440kg/cu.m
then the volume would be 0.034472 cu.m
Which is better a crawl space foundation or concrete slab foundation?
without knowing your climate, the best would be a crawl space with a concrete slab.
Why tower of Pisa is not straight same scientific reason?
The soft sand beneath the tower caused subsidence over the many years after it was built, it was in fact straight when built! Don't build your house on a foundation of sand comes to mind!
