What Does Slot Trenching Mean In Construction? Slot trenching is a construction method involving the excavation of narrow trenches for the installation of underground utilities such as pipes, cables, and other infrastructure. It is performed using hydro excavation equipment which can be used to search for or verify utilities in sensitive areas, clear an area […]
What Is Potholing For Underground Utilities? Potholing for utilities is a non-destructive digging process that uses vacuum excavation to dig precision holes over and around utility lines. It involves making a series of small test holes in order to accurately locate underground lines, such as water, electrical, gas, telecommunications, and fiber optic lines, while keeping […]
What Is A Belly In A Sewer Line? A sewer line belly is a downward bent section of the pipe that impedes the natural flow of waste. It can be caused by geological events such as soil erosion, foundation settlement, or earthquakes, or by human error like poor installation. Sewer line bellies are easily confused […]
What Does Cross Bore Mean In Drainage? A cross bore is an underground utility line that was inadvertently bored through a sewer, septic line or other underground utility. It can occur when trenchless technologies such as directional drilling are used to install new utilities in urban areas, and the equipment operator feels no different than […]
What Is Hydrovac Excavation? Hydrovac excavation is a soil removing service that uses pressurized water to create a dirt slurry, which can then be vacuumed out of the ground. It is an increasingly popular alternative to mechanical excavation due to its safety and efficiency in digging around existing utilities such as gas mains and power […]
What Is Form Traveler In Construction? A form traveller is a type of travelling formwork system used in bridge construction. It enables the repeated construction of structural elements and is typically used for free cantilever construction of post-tensioned box girder and cable-stayed concrete bridges. Form travellers are supported by the part of the structure already […]
What Is Extension Of Time Claims In Construction? An Extension of Time (EOT) claims in construction is a request for a change in the scheduled completion date due to a delay that is not the contractor’s fault. The delay could be caused by natural events, owner-caused delays, or other factors outside of the contractor’s control. […]
What Does Phenolic Insulation Mean In Construction? Phenolic insulation is a type of rigid foam insulation used in construction. It is manufactured by combining high solids and phenolic resin with a surface-acting agent. Phenolic insulation has a high closed cell content and fine cell structure, making it lightweight, easy to transport and handle, and resistant […]
What Are Thatched Roofs Made Of? Thatched roofs are traditionally made of dried grasses, straw, and other plant materials. Common thatching materials include water reed (often known as Norfolk Reed), longstraw, combed wheat reed, sedge (a grass-like plant which grows in wetland areas), straw, stems, and palm branches. Synthetic thatched roofing is made out of […]
What Is DPC On Building? A damp-proof course (DPC) is a barrier through the structure of a building designed to prevent moisture from rising by capillary action, such as through a phenomenon known as rising damp. This barrier is typically made of durable, impermeable materials such as slate, felt paper, metal, plastic, or specially engineered […]
