Demolition services in Fort Collins, CO? Excavation safety is a combination of safety precautions and mitigations in and around excavations and trenches to eliminate or control hazards in compliance with industry standards and regulations. Why is Excavation and Trench Safety Important? Excavation and trenching are amongst the most dangerous operations in the construction industry. Dangers can include cave-ins, falling loads, hazardous atmospheres and hazards from using heavy equipment. Regular pre-work inspections can reduce hazards and serious risk of injury. Safety inspections should check for the type of excavation being conducted, support and warning systems in place, access areas, weather conditions, heavy equipment and PPE.
Renovating involves making countless decisions, from which improvements to make and the choice of fixtures and fittings, down to the route for new services such as plumbing, or how details should be finished off. Many of these decisions need to be made quickly if they are not to hold up work, and so you need to allow time for this, based on what will be the most practical and aesthetically pleasing solution. If you leave such decisions to builders, they will invariably do whatever is easiest and quickest for them, and this can look awful. The trouble is, once the work is done, you have to pay twice if you later want to make changes and the builders will hate you for it too. A good builder should warn you well in advance of the decisions that they need you to make. Listen to them, spend time on site visits, and keep up to speed.
OSHA defines excavating as “any man-made cut, cavity, trench, or depression in an earth surface formed by earth removal.” A trench is a type of narrow excavation in which the depth is typically greater than the width, which does not exceed 15 feet. According to this definition, all trenches are excavations, but not all excavations are trenches. The specific safety requirements for trenches depend on the depth of the trench.

Which retaining wall blocks are best? These solid blocks are heavy. Lighter, hollow blocks are available, but they can’t be split because cutting them will expose the voids. Also, some hollow blocks require individual backfilling, which is time consuming. These pros prefer Versa-Lok blocks, which are held together with pins rather than a lip on the bottom because pinned blocks work better on tighter curves, and the flat bottom makes them easier to stack. They have also found that the small back lip on some lipped blocks can be prone to cracking, which will weaken the wall.Shorter retaining walls, however, can be constructed by enthusiastic do-it-yourselfers equipped with some basic construction knowledge. Does that sound like you? If you’re looking to get your hands dirty and enhance your landscape with a retaining wall, these guidelines for building a retaining wall will help you get off to a good start. A retaining wall’s effect on the natural flow of water could impact your neighbors, so some communities require homeowners to obtain a permit before construction commences. You may have to submit plans for your wall and schedule a property inspection to ensure that building a retaining wall won’t create drainage problems.
NFC can either be mixed on-site for smaller areas or purchased from a reputable concrete supplier and trucked in for larger commercial applications. NFC is mixed at a 6:1 ratio by volume of 20mm max size clean aggregate and cement. Water content should be such that the cement slurry evenly coats the aggregate and retains a wet/glossy appearance without excess slurry running off, this is typically around 40 litres per 100kg of cement. With the use of NFC, we are able to build Block Retaining Walls in areas and situations where normal construction methods would not work. Some of these situations are: In areas where excavation behind the wall is limited either due to being on a boundary or close to other structures or footings. Find additional details on this website.
