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.
Removing original period windows and exterior doors can destroy a period property’s character, and its value, unless they are sympathetically replaced. Authentic replicas are expensive, so always consider repair as a first option. Cheaper, off-the shelf joinery is rarely appropriate and is unlikely to fit the original openings and so will look wrong. If the original external joinery has already been removed, research neighbouring properties or books to find appropriate styles. Avoid modern hybrid products, such as front doors with built-in fanlights. Try and observe the techniques and materials used in the building’s original construction and try and repair, or replace, on a like-for-like basis. Internally, try and preserve original doors, floorboards, fireplaces and plaster mouldings if they are still intact.
Trenched areas sometimes have depleted oxygen levels, which is safety hazard that must be taken into consideration on excavation sites. The atmosphere in trenched areas can also be contaminated by toxic gases and chemicals. For these reasons, OSHA requires atmospheric testing to be performed by a qualified professional in excavations that exceed four feet. If atmospheric hazards are present, then workers must wear the appropriate respiratory protection equipment depending on the hazard in the excavated area.

If the wall runs up a hill, continue each base course into the hill until the top of the second course is level with the grade, and then start your second base course at that point. If you have the option, it can be easier to excavate and lay the lowest course before excavating the trench for the next step, especially if you have to step up several times. Save yourself some money and install the cheapest style/color that matches the wall style (usually the gray ones) on the bottom course since it won’t be seen.DO start with a good foundation. Your retaining wall will only be as strong its support system. For a stacked-block retaining wall that’s no higher than four feet, a trench filled with three inches of crushed rock will help keep the wall from shifting and settling. The exact depth of the trench depends on the proposed height of the wall, but follow this rule of thumb: Dig a trench to be an eighth of the wall plus three inches. For example, if you want the finished height of your retaining wall to be three feet (36 inches) tall, you’d need to dig the trench eight inches deep to accommodate three inches of crushed rock and about five inches (or an eighth of the visible retaining wall) to start the wall below grade.
First of all, what is No Fines Concrete (NFC)? Basically it is just what the name suggests, concrete without any fine aggregates or sand. It consists of generally an aggregate (gravel), cement and water. The aggregate is coated with the cement slurry binding it together, it dries with the strength of concrete but with voids or air pockets. This makes the NFC light weight and allows water to pass through its honeycomb texture. Read additional information on https://stormheart.net/.
