All new equipment and material used, must contain location specification, sizing, material type and other pertinent details.If the contract allows, add fabrication, erection, installation, and shop drawing information to the as-built.Then write down the new value and encompass it with a cloud to demonstrate the change. As-built drawings must include revised dimensions by crossing out or using an “X” to write over the original dimension. Do not delete or remove original dimensions and measurements.If you need to draw and add detailed design information, it is recommended to use the same scale in the as-built as the original design drawing scale.Avoid using words like similar, equivalent and replace them with the right and detailed information that is part of the equipment installed in the project.They are not ultimately responsible for changes during the installation process or field directives. Don’t expect that the architect or designer will stamp and sign the drawings.The following recommendations are suggested for better managing as-built drawings:
This type of system consists of a series of connected chambers. They are also well suited to areas with high groundwater tables, where the volume of influent to the septic system is variable (e.g., at a vacation home or seasonal inn), in an area where gravel is scarce, or in areas where other technologies such as plastic chambers are readily available. The chamber system serves as an alternative design to the gravel/stone system. The primary advantage of the chamber system is increased ease of delivery and construction. The gravelless systems can be manufactured with recycled materials and offer a significant savings in carbon footprint.Īn example of a gravelless system is the chamber system.
They take many forms, including open-bottom chambers, fabric-wrapped pipe, and synthetic materials such as expanded polystyrene media. Gravelless drainfields have been widely used for over 30 years in many states and have become a conventional technology replacing gravel systems. The solids stay in the tank while the wastewater is discharged to the drainfield for further treatment and dispersal. Heavy solids settle to the bottom of the tank while greases and lighter solids float to the top. The list is not all-inclusive there are many other types of septic systems.Ī buried, watertight tank designated and constructed to receive and partially treat raw domestic sanitary wastewater. Below are ten of the most common types of septic systems used. These factors include household size, soil type, site slope, lot size, proximity to sensitive water bodies, weather conditions, or even local regulations. Septic system design and size can vary widely, from within your neighborhood to across the country, due to a combination of factors.
