Construction Excavation Reveals Large Ancient Cemetery

Construction workers around the world never know what treasure they may stumble upon during excavations which is one of the reasons the construction industry is so exciting and the latest discovery has unearthed an archeological treasure dating back 5000 years.

The ancient cemetery was found in an agricultural basin near the Albanian town of Korca. The cemetery with 1000 layered graves was discovered during gas pipeline construction.

It will provide experts with more insight into the history of the area, in a country that was historically isolated by communist rule for decades.

The excavations were taking place near the village of Turan when workers found traces of a rare Neolithic settlement demarcated by holes in the ground that supported the decayed wooden skeletons of small huts.

Company Fined over Excavation Collapse

Construction companies can learn a lesson from an incident which occurred in Victoria, costing a construction firm $80,000 in fines after an excavation collapse which caused life-threatening injuries to a young apprentice plumber.

The company pleaded guilty in the Melbourne Magistrate’s Court for failing to provide a workplace that was without risks to health. They were also ordered to pay costs of $3,505.

The incident occurred as the apprentice and 2 other contractors were installing pump tanks at the site about 2 metres away from the excavated basement wall. The collapse left the apprentice partially engulfed and the 17 year old suffered collapsed lungs, 12 broken ribs, a fractured sternum and shoulder and damage to his pancreas. He had only been on the job for 18 days.

A geotechnical report had identified the site as at high risk of abnormal moisture conditions and advised that attention be paid to changes in soil moisture. Before the collapse, the site received 17mm of rainfall.

The court heard that the company, being aware of the risks should have supervised the contractors and prevented access to the site until soil conditions were properly assessed and the wall stabilised.  Find out more http://content.safetyculture.com.au/news/index.php/05/company-fined-excavation-collapse/#.Wwms3SAlE1l

Remains Dug Up at WA Museum Site

A grisly find has been made on a Western Australian construction site.

Construction workers at the WA Museum construction site found skeletal remains which turned out to be human while excavating the site.

The discovery was made on James Street in Northbridge recently, leading to the site being shut down.

Investigations by homicide squad detectives are underway with inquiries trying to determine how the remains came to be there.

Over the course of history the museum served as a home for convicts sent to WA to work. It was built in 1856.

Be Cautious When Engaging in Excavation

Essential Energy is urging all tradespeople to contact the Dial Before You Dig national referral service first to confirm the location of underground electrical assets before beginning excavation work.

Construction workers are being reminded that it’s a statutory requirement to contact the free Dial Before You Dig service prior to work.

Tradespeople should check for electrical, gas, water and telecommunication networks before digging to avoid disruption to the communities’ services.

Failure to do so will result in heavy financial penalties, Essential Energy warned.

Watch as 116 Excavators Demolish an Overpass

It took just one night for Chinese construction workers to demolish a 24 year old overpass bridge in Nanchang, which is a city east of China’s Jiangxi Province.

The bridge was dismantled using just 116 excavators to make way for the a new subway line to be built.

The optimization of the demolish plan has been praised as highly efficient, not even affecting traffic.

Watch the video below to see how they did it.

 

Great Solution to Excavating in Congested Areas

Hydrovac excavation is way to excavate in congested areas where traditional ways of excavation may be too risky because of the presence of underground cables, wires, lines etc.

The Hydrovac Excavation system is non-destructive and involves injecting pressurized water and a vacuum system to dig out soil leaving a trench completely open.

It provides a safe and easily controllable way of excavating. For more of the benefits and how-to information, click here.

 

White Card Update: Managing Excavation Risks

One of the most dangerous construction activities that can occur on a building site is Excavation. Each year workers are injured and some killed because of incidents resulting from excavation work. Most these incidents are a result of the side walls of the excavation collapsing or machinery tipping over into the trench or people being struck by the excavator bucket.

When engaging in any construction activity as dangerous as excavation, work must be properly planned, managed, supervised and executed.

Workers involved in excavation work as well as those working in the vicinity must be aware of the hazards that this type of work presents and should also be trained about the procedures that are implemented to control the risks associated with excavation work

Because excavation activities can involve significant hazards a high degree ofmanagement commitment is required which should involve a hazard identification, risk assessment and development of a safe system of work.

Workers involved in excavation work should be protected using shoring support for the excavation, battering sloping the excavation or other suitable methods.

A risk assessment must be carried out depending on the activities that will be undertaken and a safe system of work should be prepared and implemented toprotect workers.

  • Some of the most common hazards related to excavation work are:
    contact with underground services
  • contact with overhead lines
  • collapse of the excavation’s sides
  • materials falling onto people working in the excavation
  • people and vehicles falling into the excavation
  • people being struck by plant
  • undermining of nearby structures
  • ground water
  • soil
  • access to the excavation
  • fumes
  • accidents involving members of the public.

Remember the following basic tips when working with trenches:

  • Ensure that adequate personal protective equipment be utilised correctly. Workers should have received training on the relevant PPE because if not used correctly, their effectiveness is reduced. The risk assessment stage of construction safety should determine which PPE are to be utilised depending on the hazard present.
  • Ensure the appropriate signage to warn workers not involved with trench work of the hazard and others visiting the site of the hazard.
  • Avoid solitary work because of the possibility of collapse. It is simply not safe to work alone in a trench or excavation. If the trench should collapse or an accident should happen you may only be found much later when it is too late to get help or medical assistance.
  • Erect the proper barricades to keep workers separated from the hazard as much as possible.
  • Never try to gain entry into a confined space unless you are trained to do so because these spaces present a unique hazard that can be deadly if you are not sufficiently trained.
  • Tunnels, shafts and trenches should have entry and exit openings that are large enough for a properly equipped person to pass through without danger of it collapsing. The size and number of openings also have an impact on the ventilation which needs to be kept in mind.
