Electrical Work in Levin

Levin is a reasonably large town with a residential population that is growing at a steady rate. New houses are always being built in the town and on the surrounding farms, but the rate of new buildings being erected is not sufficient to sustain more than half a dozen electricians doing the pre wiring and finishing work.

Fortunately for the electricians the housing stock in Levin is quite old, and so there is a continual supply of old houses needing their wiring repaired or replaced. Because Levin is so small most of the electricians will be well known to a large proportion of the population, and so word of mouth reference is the more common way to find them rather than simply searching on Google for electrician Levin.

A lot of the housing stock in Levin is so old that the wiring needs to be completely replaced, as does the switches and light fittings. The easiest way for the electrician to do this work as if the house wall linings are being replaced at the same time, as it is way easier to run new wiring an empty wall cavity then to have to run up behind an existing wall. In many cases the wiring needs to be replaced because it is so old that it is dangerous and a fire risk, and the homeowner is probably finding that often the switches is don’t work properly or reliably. Upgrading old wiring is essential if the house is to be sold, and in any case the new switches and light fittings can look very flash in a old house and can add significantly to the value.

Often old houses need their plumbing upgraded as well, and this almost always involves installing a new hot water system which definitely needs an electrician. Sometimes the homeowner chooses to use an instant hot water system which requires quite tricky electrical wiring.

In many cases old houses also need an alarm system installed, and a good electrician is required for this particularly if security lights and alarms are installed around the outside of the house. It is important that these operate reliably, so that the homeowner and even more importantly potential burglars know that the technology is keeping the house safe. Also an old houses the electrician will need to install the communication cables such as the fibre optic cable in the wiring necessary for television and audio systems. The work for an electrician in Levin can be varied and very busy.

Safe Building Techniques

Almost all new houses built-in New Zealand news wooden frame use wooden framing, using timber extracted and build from New Zealand exotic pine forests. All the timber used in the framing is treated, and provided the frame goes up quickly and the roof is put on before the frame gets too wet then the timber should dry out nicely and not move at all after the house is built.

The frame gets delivered to the site with all the walls and roof trusses premade in a factory, and once the concrete floor has been poured and has been cured for 2 to 3 days in the frame can be erected very quickly indeed. What’s the frame is up and has been firmly connected to the floor and the other frames then under New Zealand law scaffolding must be erected around the entire house. Old style builders may scoff it was apparent extreme level of safety, but the law is the law, and all new houses must have a safe working environment inside and outside the house for the workers.

Accident statistics speak volumes, and the level of accidents due to falls on a building site have been reduced enormously since the introduction of this law. The requirement for scaffolding obviously adds a delay to the project and adds not insignificant cost, but the return on investment is real given that huge long term cost of any accident.

All building sites must also have very clear signage on the front fence explaining that the site is it dangerous area and listing the dangerous. Or building sites must also be completely fenced off to prevent random individuals from entering the site. This can appear to be overkill to old style builders, but when taken in conjunction with the other safely steps that creates a safety mentality for everybody on the site and the results definitely show this.

Old style builders can be very dismissive of some of the other safety steps, including installing hooks around the ceiling years of every room so that netting can be hung while builders Christchurch are working in the roof space. The law surrounding the safety netting is a direct result of analysis of long-term statistics for work site accidents. The meeting is only removed once the roof has been installed and no more work as needed inside the roof space.

The combination of secure fencing, good standard safety signage, scaffolding around the entire house, internal netting and a constant focus on safe behaviour means that accidents on building sites have decreased dramatically in New Zealand over the last few years. The foreman or team leader also must lead a safety discussion at the start of each day, so that all risks are identified and safety steps decided on. Whenever a new subcontractor comes on site then the building team leader must repeat the same message to the new subcontractor.

One disadvantage for the new homeowner is that they are no longer allowed to wander through the site whenever they want to in order to check building progress. This is a small price to pay for the increased safety for all workers in the site.

Heavy Machinery Operations

Heavy machinery is an essential part of any modern construction project, and along with the heavy machinery is there skilled operator and the skills support crews working with the operator. It is important to learn how to become a crane operator.

On a modern high rise building site the most visible heavy machinery is the tall crane towering over the site  and over the surrounding City. The casual Observer wonders about the mentality call someone who is prepared to climb the very skinny Tower every morning and sit there even in recently high winds concentrating on moving heavy machinery and equipment and materials around the building site.

Crane operators are a special breed, as they need a high degree of skill and coordination to operate the crane safely and efficiently, a degree of fitness in order to climb up and down the tower everyday, and a strong nerve in order to operate themselves safely at height.

The work is highly technical, and requires a good Communications system between the ground  crews and the operator. The operator needs to know the  weight of each load so that they can safely judge how far out on the crane the load can be moved. The cranes are very carefully counterbalanced and have Smart Systems in place to measure the loading and indicate when a problem is likely to arise, but it still needs a skilled and experienced operator to interpret the systems and operate the machinery.

One particular danger for the contractors and builders on the  site is that heavy loads are being moved around above their heads. A skilled builder or labourer is required to make sure there is load is very firmly attached to the crane, but mistakes do occasionally happen and every builder on the site needs to be aware of what the crane is doing at all times.

One particularly high tech  operation that all crane companies need to carry out is the erecting of the crane and the  steady  raising of the crane over the life of The Project as the high rise building precedes skywards. This work involves the crane lifting its own frame, and while it looks complex and dangerous all  crane companies have mastered this operation and it’s always carried out safely. At the end of the project the crane must dismantle itself and Lara itself to the ground, and this is also a high skilled and technical operation that needs to be worked through via a series of set steps.
