Civil Engineering Construction, Then And Now

Posted on January 31, 2019 by blogger

Civil Engineering is one of the oldest scientific disciplines known to man. Early signs of professional engineering can be traced back to 4000 BC with the Egyptian and Mesopotamian civilizations. The Egyptian pyramids till today remain a marvel to mankind, as to how in that day and age such massive structures could be constructed. With such precise calculations and engineering knowledge required they truly are wonders of the world. In those times with no electricity or heavy machinery at their disposal, getting huge rocks to move in their place with sheer manpower is an amazing feat in itself. More examples of early evolvement can been in the Indus valley civilizations where elaborate waterways and structures were built.

Since then civil engineering construction has evolved greatly. Today it has been further split into various multi disciplines such as structural engineering, geo technical engineering, environmental engineering etc. All these disciplines are core specializations in them selves and require in depth study. We today have heavy machinery at our disposal, which has helped the field evolve much faster. With machines available,loads of much heavier weight can be moved much faster.

The need for manpower has come down drastically as machines take on the task of many men single handedly. We have been able to build elaborate structures across difficult terrains, which would not have been possible earlier. Precision work has increased dramatically and has become increasingly easy. Machines of all types such as excavators, compactors, rollers, bulldozers, measuring instruments, cranes, dumpers etc. have been made available for different construction activities.

Lets talk about some of these important machines that changed the construction industry further in brief:

Excavators: An extremely important and widely used piece of machinery is used across a variety of industries such as construction, mining, forestry, demolition etc. The main purpose of the machine is to dig up earth fast. The mechanism of the machine consists of a boom, stick, bucket and cab sitting on top the main assembly also known as the house. Excavators are also available in 360 formats where they have an all round motion capability.

Cranes: Another very important piece of machinery that is used in its smaller format inside workshops too much larger projects involving bridge and skyscraper construction. All the skyscrapers we see today would not have been possible without the availability of cranes. The ability of a crane to move heavy material swiftly to great heights and horizontally is unparalleled by any other. Cranes have greatly reduced the time taken in construction and are responsible in a big way in fuelling construction growth seen over the last 150 years.

There are mainly 3 types of cranes overhead, fixed and mobile. Furthermore under mobile cranes there are various more varieties such as truck-mounted cranes, rough terrain cranes, floating cranes, rail road cranes, crawler cranes, pick and carry cranes etc. In the fixed type of cranes some of the following varieties exist such as tower crane, gantry crane, deck crane, loader crane, jib crane etc.

There are many more important pieces of machinery that we will look at in our next article.

You can see how over thousands of years civil engineering construction has evolved from mere chisels and hammers to sophisticated heavy machinery. How it has sped up the growth of the world and help us build elaborate cities and infrastructure that we use everyday.

Pools – A Review of Construction Styles

Posted on January 27, 2019 by blogger

Pools can be a great addition to your home, for entertainment or even raising the market value of your home. However, if poorly constructed, they can also become a money pit. Homeowners who are considering building one probably have no idea where to start. There are many options to consider when planning for your new recreational space, so it is easy to become confused, even before you begin making the actual building plans. It is important to take the planning stages one step at a time. Owners must consider how they plan to use the pool-will it be used for entertaining or exercise? First and foremost, the owner should make an effort to learn more about the different types of constructions available.

Aboveground pools: Generally, this style is made from a pre-fabricated kit. To install, you must first level the ground so that you can build on a flat surface. A perimeter track, which is made of metal, plastic, or wood, is then assembled to support the outer wall. Sand is spread around the area and plumbing is laid. The last step is to apply the liner to the walls. It is then filled with water while the liner is smoothed and fastened into place. Aboveground styles are cheaper, easier to build, and less permanent. They are also less durable and less attractive.

Fiberglass pools: Fiberglass-reinforced plastic is molded into a basin shape for this particular style. After the basin is made, crews dig a hole big enough to fit it and lay the plumbing. Sand may be spread as filler. Crews then lower the pool into the hole and level it out. The pool is ready to use after the plumbing is hooked up and the area is backfilled.

Vinyl-lined in-ground: This style is similar to the aboveground. Crews dig a hole, as with fiberglass pools. They then assemble a frame made from metal, wood, or plastic around the hole walls. Sand is laid at the bottom of the hole, and the lining is secured to the wall. This style is cheaper than standard in-ground styles, but not as durable, as the liner must be replaced every 10 year.

Gunite: As with the other in-ground styles, crews dig a hole, place plumbing and assemble a frame of steel rods. These rods are secured with wire, and then sprayed with a coating of gunite, which is a mixture of sand and cement. This mixture is smoothed with trowels. After the mixture sits for a week or more, workers apply a smooth finish to the surface. Gunite can be finished with any number of materials, such as tile, cement paint, or fiberglass. This style is durable, and can be made to any shape or size.

Poured-concrete and masonry-block: This style is like gunite, except concrete is actually poured into a wooden form instead of a frame made of steel rods. Pools made of masonry blocks are constructed with concrete blocks.

Make Your Construction Easy With Propping Equipment And Accessories

Posted on January 22, 2019 by blogger

The propping equipment and accessories have moved up their standard to meet the advancing building industry. Now, there are wide ranges of high versatile propping equipments and accessories available to make the project run smoothly and safely. Some of the propping equipments that is necessary in most construction sites are the tilt props, acrow props, titan props, multi props, trishore props, slim soldier and the megashore props along with prop accessories like t locks, sleepers and needle beams. These propping equipment and propping accessories have become very necessary to support the construction of new buildings or structures.
The tilt props are used in tilt up slab constructions and the push pull prop is often used for high load applications. The titan prop has the ability to support an immensely heavy load. These Titan Props are suitable for tight and tricky access applications. The titan Props are available in different sizes and easily handled. The trishore props can support heavy loads at a considerable height. When they are braced in groups, they can support exceptionally intense weights. It is economical better regarding labor and transport. The slim soldier props offer heavy-duty support for the raking and vertical applications. They are popularly in use with on many works like civil engineering and building. They can support both large walls and precast units. They can also be converted into push pull prop with proper connections. Megashore props are design to support axial loads of up to 100 tons. It is highly versatile and can be used in heavy lifting towers, bracing for excavations, shoring/trusses and support spines for tunnel formwork. For heavy-duty false work, cofferdams, bridge launching, bearing replacement, facade retention and excavation support the megashore props are highly used. The multi props are very light as they are made up of aluminum and have a longer service life than steel tubing. The acrow props are used in almost all constructions for temporary support. It has a quick and simple method but otherwise very useful technique.
The propping accessories are used along these propping equipments. The T Lock is used in tilt prop industry as a built lock. This is an auto lock system, which allows easy installation and prevents tampering onsite. Sleepers are use as grid patterns for forming base pads or sole plates in order to support the load on the surface. For the propping and needling applications, the needle beams are used.

The Uk Construction Trade’s Decline

Posted on January 17, 2019 by blogger

There is some dangerous news for those of you who step into your protective overalls for every day on the construction site every morning. Analysis by the Construction Merchandise Association (CPA) has shown that the construction business is going to continue declining for three a lot of years. Output is anticipated to fall by virtually 10 % this year and another four % the following year. This forecast is a lot of grimmer than previous reports and if this decline happens as predicted, it will be the most important decline in 30 years.

Chief executive of CPA Michael Ankers said, “The speed of decline is having a dramatic impact on many elements of the construction industry and is being driven by an unprecedented reduction in personal sector investment resulting from the credit crunch and economic downturn.”

The credit crunch affects all business sectors, significantly the motor and property industries, and the development industry is certainly no exception. The house building and repair sectors are the toughest hit with house starts expected to fall to their lowest level since the fifties and maintenance and residential improvements expected to fall by 15 % this year alone.

In addition to the present grim forecast, past construction output speaks volumes. Within the last 3 months of 2008, construction output within the UK came to ?19.3 billion which is ?1.5 billion down from the identical time period in 2007. But, the total output for 2008 was just about on par with the overall output for 2007.

However, construction output in some areas is seemingly to extend in the following years. Rail construction work ought to increase dramatically in the subsequent five years; the CPA report has predicted that it can increase by a hundred ninety%. Additionally to the current, public construction that is not housing-connected will go up by over 20 p.c in the following 2 years. Michael Ankers has asserted that the only sectors where construction output is forecast to extend are linked to public spending.

Spending on construction for education is expected to extend by nearly 30 p.c in the next 2 years, mainly because of the Building Colleges for the Future programme. The development trade is relying heavily on public spending throughout the recession. Luckily for those utilized within the trade, spending on public construction comes creates significantly more employment than different sectors of the trade and mainly British merchandise are used. This is often really the silver lining of the recession storm cloud for the trade and the well-developed British public sector is to thank for this.
