Reconfigurations of Level II changes are those where existing structural systems are replaced with new ones. There are many reasons why a structure may be undergoing a structural change. These could include; replacing an existing system with a new one, extending or modifying the current system, adding on new space or rooms, or making repairs to the existing structure. Most structures have the potential to undergo a level 2 change, but there are some which are structurally safe and require little or no changes. Those requiring level 2 changes are usually those where structural elements have been changed or replaced with newer or more efficient systems.
Types of Reconfiguration
A number of different types of reconfiguration may occur within a building. Each type has specific requirements for its execution. They include level 1 alterations, level 2 alterations, level 3 alterations, structural modifications, and roof additions or roof retractions. A qualified engineer should be consulted to assess the suitability and feasibility of any proposed reconfiguration.
Level 2 Reconfiguration
Level 2 reconfiguration involves the structural alteration of the existing structure in order to improve accessibility or make the building safer and more comfortable. This type of change involves the movement of walls, opening up doorways, modifying interior spaces, moving furniture, reconfiguring lighting, and other similar activities. To carry out a level 2 reconfiguration, a construction worker must first identify the affected space by carefully examining the building area map, if there is one. The extent to which the change will affect accessibility is then assessed, including any changes that may be required to access certain areas of the property.
A contractor or architect who is employed in the planning, design and implementation of alterations can advise on the best course of action for a particular project. They also offer specialist knowledge in the planning and design of roof additions and can recommend the most suitable contractor for a particular job. The role of a professional in a reconfiguration can also include taking measurements and photos of the work area. These photos can be retained and used as evidence during a legal claim.
In order for a roof to be made accessible for wheelchair users, the location of wheelchair ramps must be carefully considered. If the ramp cannot be located where it is required, a new and usable exit ramp must be constructed. For premises that are too dangerous for workers to work at, special mechanisms to remove ladders from the roof can also be installed. Similarly, a roofing company may need to install safety railing around work areas. This is especially necessary in areas where there may be inadequate electrical power. Safety precautions will also need to be put into place during construction, and these may include placing signs advising people about the nature of work being carried out, and putting up warning boards.
There are several different types of roofing systems, and this includes pitch, tabular and cantilever. When installing a new roof, the pitch must be selected to match the natural line from the building’s apex to the lowest point where snowfall meets the roof. This ensures that water flows in the same direction as it was originally heading and provides for an even distribution of snow distribution. It is important to keep in mind that pitch must never be too low or steep, as this can compromise the structural integrity of the roof. It is also advisable to avoid pitch that is too steep because it can compromise the safety of workers during high winds, as well as damage the roof if it should fall down.
After the roof has been properly fitted, it is important to address the drainage requirements. This includes the type of drainpipes, which are usually either ventilated or non-ventilated. Non-ventilated drains are better suited for roofs of lower levels and are therefore more popular, whereas ventilated drains are better suited for roofs at higher levels due to their increased ability to resist moisture. The type of roofing materials to use is also important, as the materials provide the framework upon which the roof is built. While the generalist may be able to install a level 2 roof, it is usually advisable to employ a professional to ensure that the roof is installed correctly, with no defects.
Once the roofing material and system are installed, it is time to address the protection required from the weather. This involves ensuring that any necessary structures are installed and that any loose shingles or tiles are appropriately secured to avoid them becoming airborne in high wind. It is also important to check that there are no penetrations in the roof, as this can lead to moisture being able to enter the building, which can lead to mold or mildew. Finally, it is important to ensure that any maintenance work carried out on the roof follows set guidelines and is scheduled in advance of its use. If these are not followed, the chances of the roof becoming faulty far outweigh the benefits of its repair.
