Tree protection if an important part of any construction plans and trees can be vulnerable when situated near development sites. All development and construction companies have to take this into consideration and organize the approved protection. Firstly when considering proposals for development it is important take into account the effect such developments may have on surrounding trees and woodland. Trees are active in improving our quality of life and not only are trees great to look at they also offer shade, help absorb noise and provide our wildlife with a home. Contacting your local council to clarify if any trees or woodland has a preservation order is a must. This means that trees on site or within close proximity to the site will be taken in to consideration when planning. When protection your trees you would need to be in contact with a specialist Tree protection company that will also be able to advise you of your requirements for protecting trees. These trees will be protected to British Standard BS5837 this to ensure that trees are appropriately and safely retained when development takes place. A tree protection plan consists of where the location of the protective fences or barriers is situated, the location of where your plant and machinery will be stored, drainage runs, roads, driveways and any other surface or underground features that may affect the tree on or neighbouring the site. These points all need to be taken in to consideration.

Basically tree protection consists of Heras fencing or hording with a scaffold support system behind to prevent the fencing falling on the trees or woodland knocked by machinery the barriers will not damage the tree or trunk. This fencing is placed different distance for each tree,when erecting tree protection fencing allow 1 foot of space form the trunk for each inch of trunk diameter or another way is the height and span of the trees should be the distance in which the barrier should be from the trunk. If you are unable to find a Tree protection specialist in your local area, most scaffolding companies have experience in erecting protection with the scaffold support system. A lot of construction companies use a local scaffolding team for their general scaffolding but will also ask them to incorporate tree protection in to their work. So it is worth asking if they are able to complete your tree protection needs.

Spring has arrived, a little cold still and parts of Scotland are still getting snow? However it is now getting warm enough to start your home improvement projects, there is nothing better than getting out in the fresh air. It is now just about dry enough to start cutting the grass. A lot of people are now looking too summer still in out in the garden having a BBQ but your garden needs a facelift, everyone is opting for decking these days but this can now work out rather expensive not only do you have to purchase the wood for the frame but then the decking to sit on top. There are cheaper ways to do this and due to current economic climate everyone is looking to save money.

When looking to save money I soon realised there are other ways to create the perfect decking or garden borders at the fraction of the price. If you are handy with a sander, saw/jigsaw why not try and contact a scaffolding company and ask if they sell any of their scaffolding supplies. These companies will have new and used scaffold boards and I am sure would be willing to have a deal to sell scaffold boards that can no longer be used for scaffolding? Scaffold firms have strict health and safety regulations to adhere to when using boards to ensure they are sturdy and safe enough for people to walk and work on so you can imagine the volumes of the boards they would go through. Not only will you be able to get a bargain price but you can rest assured this wood is of high quality made from pine whitewood and treated with osmose naturewood to protect the wood from rotting. However make sure you can go and have a look through and take your pick as there maybe some scaffold planks that are just not suitable. With a bit of sanding down they will be as good as new and would look great a decking or even the decking frame. If you are looking for garden borders Scaffold boards are great, normally the trendy option would be sleepers but they are very very expensive as they have become so popular. Why not try Scaffolding boards less of a dent in your pocket and do actually look great as a border. No garden? Maybe you have an allotment; these boards will work as a great border for your vegetable patch. The options are endless if you are experimental and are looking for a challenge; why not make your garden furniture?  The average price these days for wooden garden chairs and table sets are £500 so if you can why not create something rustic. I hope this has given you some inspiration and money saving tips to create the perfect garden.

In general not many people know about or understand what scaffolding is or used for? Also it has been said on occasions that building companies feel scaffolding is an extra expense when trying to keep to budgets. However scaffolding is an important requirement for new builds, construction sites and general repairs & maintenance to buildings. As an example if want to repair your chimney on your four bedroom semi in Portsmouth, you could use a ladder and struggle to climb up on your roof to get to your chimney but this is NOT recommended, think of your own Health and safety before even contemplating anything of the sort. The safest option would be to spend a few extra pounds and easily contact a company for scaffolding in Portsmouth, who specialize in erecting a safe and secure access scaffold, so you can make your repairs safely without injuring yourself or causing harm to others. Scaffolding can erected quickly and easily ensuring that your property and surrounding areas are not damaged in the process, dependent on your requirements the price for scaffolding can be pretty reasonable too. Scaffold companies can professionally advise you on what requirements are needed for different types of works. From a simply access platform to a more complex temporary roof or a support scaffold. Scaffolding is one of the safest ways for access to high, hard to reach areas and every construction site would be lost without it  – how else can you build a house 30 ft high?  With strict health and safety regulations and site inspections, the safety of workers is paramount.

When looking for a scaffolding company ensure you check the following, all scaffolding companies should have public and employee’s liability insurance, you should be offered a free quotation, they should have a risk assessment and method statement and are to produce these if asked. If looking online make sure the website has plenty of contact details, office address, company number and a portfolio gallery of work completed. Check to see if they are members of associations, many scaffolding companies are members of professional bodies or schemes and have to adhere rules and special requirements in order to become accredited. If you are looking for a local scaffolding company also take a look on Checkatrade this is a well know company who vets all trades and publishes customer feedback so you can check how scaffold companies have performed by viewing honest customer reviews.

There are many different buildings that are categorized as secure buildings. These buildings often feature access control locks and even finger print identification systems. Today there are even iris scanners that are used to identify the person entering the facility by scanning the iris in one or both of their eyes. Obviously, the more security that is needed, the more elaborate the Access Control Solutions will be.

Buildings like research facilities must keep the contents of their labs secure as there are many potentially dangerous items found within them. Things like diseases and explosives or even subjects who have been infected with a specific illness can be found inside of a research lab and for this reason security is a number one priority for buildings such as these. Hospitals also have areas that are locked and require the use of access control devices in specific locations. Usually patient areas and pediatric areas use these access control systems to ensure the safety of the people who are located inside the units.

Federal buildings such as the FBI office or the Department of Motor Vehicles also use access control systems to be sure that no one who is not supposed to be there gets in. There have been a lot of incidences in which crazed gunmen have entered buildings such as these and gone on shooting sprees. This has caused the federal government to up their security significantly. In addition, the terrorist attacks of the past decade have also contributed to the need for heightened security.

Schools are also a very common place to find enhanced security features because there have been many breaches in security in schools and sadly, a number of school shootings over the past couple of decades. For this reason the school boards go to great lengths to install state of the art access control features to their buildings.

Un fortunately, no matter how much security you have in place in any given situation, there is still always the possibility of a dangerous situation occurring in which security has some how been bypassed. However, by making sure that you have extra measures in place, you are taking steps to protect the people as well as contents of any building.

As impressive as some our modern inventions may seem, there is always a chance for our designs to fail. To err is human, as the old adage states. Major endeavors, such as the design and construction of a new building, rely on the collective knowledge of hundreds of individuals. Having said that, the success of any project will depend greatly on the weakest link in the chain of knowledge. This is precisely the reason mechanical engineering jobs are in such high demand. The following is a collection of the three worst engineering failures in the modern era.

Space Shuttle Challenger Disaster

On January 28, 1986, the Space Shuttle Challenger disintegrated off the coast of Florida causing the deaths of its seven crew members. It is believed that an O-ring seal on the right solid rocket booster failed, causing a breach in the joint and allowing hot, pressurized gas from within the rocket motor to escape. This led to the structural failure of the external tank and precipitated, with the assistance of aerodynamic forces, the complete breakup of the vehicle. The failure of the O-rings was attributed to a faulty design by the Rogers Commission.

Chernobyl Nuclear Meltdown

On April 26, 1986, the world witnessed the worst nuclear power plant disaster in history at the Chernobyl Nuclear Power Plant in the Ukraine. The resulting explosion(s) resulted in the release of significant amounts of radiation into the atmosphere, producing over 400X more fallout than the bombing of Hiroshima. While human error may have played a role in the disaster, flaws in the design of the control rods are thought to have been the root cause of the accident. The authorities remain largely unsure of the effects of the radiation exposure, and the area is still heavily contaminated over 20 later.

New Orleans Levee System

In August of 2005, a series of hurricanes hammered the areas in and around New Orleans, Louisiana. It is believed that there were over 50 individual failures in the levee systems and flood walls intended to protect the city of New Orleans. These levee failures contributed to the flooding of over 85% of the city, with some areas under ten feet of water or more. In 2006, the U.S Army Corps of Engineers, in testimony before the U.S Senate Subcommittee on Energy and Water, conceded that there were “problems with the design of the structure”. New Orleans, Louisiana remains a disaster zone to this day.

A duct system is used as part of a building’s ventilation system; the ductwork includes ducts and connecting ducting. The ductwork system provides the delivery and removal of air within the building, whether this is warm air or cool air depending on the temperature requirements of the building.

Ducting is a crucial part of a HVAC system and in order for an efficient HVAC system it is crucial to seek professional help from ducting experts. A poorly designed system will be inefficient and the airflow around the ductwork will be affected, which will have a knock-on effect on the conditions of a building.
The tubing for ductwork is typically manufactured from:

• Tin
• Sheet metal
• Fibreglass
• Flexible plastic

Developments in material technology have seen the popularity of flexible ducting increase as they are much easier to install than the rigid sheet metal tubes. The plastics used also have much more favourable insulating properties than their metal alternatives, again helping increase the efficiency of the ventilation system.

Ductwork can also be used as part of an industrial exhaust system to remove materials/particles from the air in buildings/work places. The pipework of an industrial duct system is used to convey the particles from the point of collection to the chimney (outlet). With industrial ducting it is again crucial to ensure that the system is designed to be as efficient as possible to ensure that operating costs are minimised while at the same time providing a safe and comfortable working environment.

Designing an exhaust system or ducting system is affected by the principles of fluid mechanics and clearly the longer the piping used, the greater the level of resistance and therefore the greater the capacity of the blower that is required. Getting the design of your ducting right first time is crucial as corrections at a later date will be costly.
