Importance Of A Construction Safety Checklist

Posted on by blogger

Construction Safety Checklists exist since safety is paramount in any construction job. There are many dangers present in a construction site that could lead to disasters that are best avoided. It is, therefore, of the utmost importance that the principal contractor for a certain construction job make sure that the usual hazards are watched out for. It is a principal contractor’s obligation to keep aware of the many risks he or she must avert before starting and also during construction work. A Construction Safety Checklist would definitely come in handy when just about to start on the construction job. This would significantly lessen the chances of the principal contractor to miss identifying some risks in the construction site, especially those that are most frequently identified in the other construction jobs. Furthermore, it is a way to more easily check whether a construction site complies with Workplace Health and Safety Regulations.

Given all this, it is good practice to build a Construction Safety Checklist and continually add on to this as a principal contractor gets to identify more potential hazards to look out for in construction work.

One might wonder what it is that would most usually comprise a Construction Safety Checklist, so to satisfy that curiosity, below is a list of the essential things that are to be included in a Construction Safety Checklist:

– Site Inspections – Walk around the site and check for any small structure present on the site that wasn’t included in the plans and may need to be demolished, a depression that could possibly indicate the presence of something that has been buried in site or this may even lead to discovery of an underground tank that would require EPA involvement. You may also choose to hire an independent contractor to do the site inspections for you.

– Employee site orientation – Prior to starting construction work, the workers must be made aware of the unique risks and hazards present in the site. Knowing what to look out for in the site would greatly help avert disasters.

– Worksite fenced off – Placing a fence around the site would keep away outsiders from getting in and exposing themselves to the potential dangers in the construction site. Also, these trespassers may end up taking equipment or materials needed for the site. A fence would be a decent barrier that would prove difficult to go through.

– Protective equipment – After having assessed the risks in the site, the principal contractor must make sure that all protective equipment has been provided and that all workers are properly making use of such equipment.

– First aid – Verify that first aid facilities and first aid equipment are readily available and accessible in the work site. First aid response must be quick and done properly.

– Construction signs – Placing signs to inform the general public of the potential hazards of being in close physical parameter to the site would be very helpful to outsiders.

– Tools and equipment used for construction – Testing tools and equipment to verify that they are working properly is another measure that needs to be taken just before construction work starts. This must also be applied to all electrical leads or outlets. The list above is merely something to start off with and build up on. Construction Safety Checklists could have many more things included. This may very well prove to be a good starter Construction Safety Checklist for new contractors to build up on though.

Know that the checklist above is merely a list to start off with and build up on. Again, many more things could be included in this. This may be a good start though for any new contractor intending to build up a reliable Construction Safety Checklist.

The Specialization Of The Construction Industry

Posted on by blogger

Today’s Construction industry has become quite competitive. Contractors are required to me efficient, cheap, and punctual. For either a new construction project, or a remodel, contractors have the challenging task of assigning the exact price for the completed work. In addition to the obvious cost calculations for the material costs such as foundation materials, lumber, roofing, doors and windows, cabinets, carpet, paint, appliances, plumbing, electrical wiring, landscaping, and many other things, they also have to calculate the time for each task to be completed and determine the labor costs for the construction project. In the past, one contractors quote may have varied greatly from the next, simply because of the many variables involved. Construction time was usually the target that was missed the most.

Computers and software developed for contractors has enabled contractors to work more efficiently. With the use of specialized software, contractors are able to provide more accurate quotes, and determine these figures in a much shorter amount of time. The quotes provided are usually more uniform depending on the contractors own markup.

The construction industry has become so refined, that many teams of workers are assigned to their specific task. When that task is completed, their job is done, and in comes the next team. For example, once the foundation had been built, the framing team needs to come in, followed by the plumbing team and electrical team. Next is the drywall team, the carpet team, the paint team, etc. What is impressive is that each team has specific estimating software for their stage of the construction process. T

When the electrical contractor has the plans for the building, including all the square footage figures, and all the plans and electrical needs, he can simple input all that information into his electrical estimating software, including the pricing of specific electrical fixtures and the current costs of wiring, etc., and the software will calculate the final costs, including labor. Each subcontractor has a similar process and when all taken in sync, the contractor is able to provide a total estimate for the construction project.

All of this specification results in a very efficient construction industry. Of course, you can still hire a jack of all trades builder, they still exist. Just understand that it is impossible for one person to be an expert in every process, as well as being an expert in the use of all the software available. His estimates will be more variable. Either way, the numbers should make sense to you, and everything, including the time table, needs to be put into writing.

Construction Scaffolding

Cape Town, like many other major cities around the globe, is undergoing massive construction, renovation and restoration projects. People are taking notice of how striking the mixture of old and new buildings within a metropolis look, and how valuable and impressive a buildings heritage is, especially when it is centuries old.

Scaffolding enables workers, architects and construction engineers to perform their tasks safely and reliably, without danger. New makes of scaffolding allow for extra safety and allow workers to assemble and dismantle the equipment quickly without compromising safety.

Restorations
With South Africa, and especially Cape Town, establishing itself as one of the worlds favourite holiday destinations and a favourite spot to buy property, a lot of restorations are being undertaken.

Cape Town is rich with history, but the CBD and many other areas were starting to look a little dilapidated, until now. Major restorations are occurring all over the city and old architecturally beautiful buildings are being restored to their previous state of glory and aesthetic beauty whilst retaining their historical identities.

Scaffolds are contracted to help with the restorations, helping the construction teams to perfect every inch of the structures. Sky high or medium rise, scaffolding reaches the necessary locations and allows the building and construction workers to reach all the areas necessary with the highest safety standards. Scaffolding systems allow safe and quick assembly to reach every part necessary without risk of injury. Therefore the job can be done quickly and efficiently.

Building and Construction
With the 2010 Football World Cup being hosted by South Africa, the race is on to build massive sports stadiums and increase the capacity of existing stadiums in every major city within the set time constraints of the event preparations. New roads are also being constructed to manage the increased traffic in the cities and hotels are being up-sized to cope with the influx of fans needing accommodation.

Construction teams are making use of modern and technologically advanced scaffold and formwork techniques to achieve brilliant results in less time. With these new developments, less labour is needed and projects can be completed is less time than normal. This cuts costs dramatically.

Access Scaffolding
Access scaffolding is scaffolding which is often erected at construction sites for the easy passage of workers and equipment. In most construction sites, the terrain is uneven and littered with obstacles which could prove harmful if a collision of some sort were to occur. For example, steel reinforcements for concrete could cause grievous harm to a persons body if they overbalanced on an uneven surface and fell on the pins.

Equipment such as wheel barrows and heavy tool containers are allowed easier access to a construction site with the use of scaffolding and the safe passage it allows to the most hard-to-reach places of a project.

Scaffolding at a construction site is also a time saving tool. Without having to navigate the dangerous parts of the site and having a short, safe passage to the part of the project where they are working, workers cut a considerable amount of time out of their tasks.

At locations where construction is a potential injury hazard to passersby, access scaffolding can be constructed to provide a safe passage over the construction work. For example, if a building is being renovated and the pavement is inaccessible, a ramp can be built above the construction for people to pass over the top of the danger. Scaffolding can also be used as a protective cover above people in the danger zone, protecting them from any objects or dust which could fall from above them.

Scaffolding can be used in many ways to aid construction efforts. Scaffolding provides a way for builders to reach every spot on a building, as well as remain safe. Bystanders are also kept safe and work is completed more reliably and quickly as new scaffolding is easy to assemble. The many benefits of scaffolding keep it a well-used and popular construction aid.

Disasters In Bridge Design And Construction

Posted on by blogger

A country’s infrastructure is essential to its success, and having a network of transport systems in place is vital not only for the industry, but for safety too. Bridge construction forms a major part of access routes in every country in the world; from simple wooden bridges in the foothills of rural Wales, to the world famous engineering masterpieces such as the Golden Gate Bridge. The structures may be very different but they serve the same purpose, to provide safe and swift access.

In wealthier parts of the world such as Europe and the UK, the need for bridges is often a matter of convenience, for saving time and improving access and traffic flow from one area to another. In more remote parts of the world, bridges can form a vital connection to essential supplies, and without them certain sections of the population would be at risk in the event of a natural disaster or during times of conflict.

For example, during a study of the Turkish infrastructure, it was noticed that a fault line separated the country along what happened to be an economic divide. In the event of an earthquake this would endanger the lives of some of the poorest of the population as there would be no direct route for supplies and aid. This study led to the construction of a bridge that would ensure that such help would be able to reach these areas should such a disaster occur.

Designing and constructing any bridge is a feat of engineering excellence, but building bridges to withstand the rigours of some of the toughest natural environments is a marvel all of its own. Hurricanes, extreme tides, earthquakes and tornadoes are all elements that need to be accounted for when designing a bridge, and do not forget that human error needs to be accounted for too.

Some of the most notorious bridge disasters involve collapse due to impact from boats and trains. In these accidents, the piers or pilings have given way from the force of the collision and caused the rest of the structure to give way. Other bridge failures have been blamed on superstructure failure due to bad workmanship, such as poor welding, or the use of low quality materials. The final way that bridges can fail spectacularly is in the miscalculation of sums by the engineers themselves.

The mathematics involved in bridge construction involves complex equations that have to account for natural variations in the properties of the chosen construction materials and the way these materials will function in the chosen environment. Add this to the effects of a speeding train, hundreds of vehicles or the marching feet of pedestrians, and the numbers in bridge building become very complex indeed. Many bridges that have appeared structurally sound on paper have behaved in a very different manner in real life.

Some of the most spectacular of these bridge failures have been attributed to what is known as a sinusoidal wave which causes harmonic motion. There is well aired footage of the Tacoma Narrows Bridge which collapsed after the not so harmonic motion caused total structural failure. Basically, small vibrations caused by movement on the bridge accumulate until what appears to be a solid structure has a fluidity that resembles the movement of a wave in water. In some cases, this movement subsides if the causes of the vibrations cease, but in other cases, once the process is underway, the movement becomes self- perpetuating until collapse occurs.

A similar occurrence happened when the Millennium Bridge was opened to the public in 2000. As pedestrians crossed the river the vibrations of the footsteps caused the bridge to sway slightly, and as it did, those crossing had a tendency to walk in time with the movement which served to feed the harmonic motion. Fortunately the bridge was closed without there being any injuries, and over the course of a couple of years the design was modified slightly to prevent such an event happening again. The conclusion is that there will always be a fine balance between engineering genius and pushing the limits of physics itself whilst engineers strive to provide easy or essential access to remote areas and popular destinations alike in the name of technological advancement.
