Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm). TDS in water can be measured using a digital meter. [1]
A material take off (MTO) is the process of analyzing the drawings and determining all the materials required to accomplish the design. Thereafter, the material take off is used to create a bill of materials (BOM). Procurement and requisition are activities that occur after the bill of materials is complete, distinct from Inspection.
A bill of materials or product structure (sometimes bill of material, BOM or associated list) is a list of the raw materials, sub-assemblies, intermediate assemblies, sub-components, parts, and the quantities of each needed to manufacture an end product. A BOM may be used for communication between manufacturing partners or confined to a single ...
A bill of quantities is a document used in tendering in the construction industry in which materials, parts, and labor (and their costs) are itemized.It also (ideally) details the terms and conditions of the construction or repair contract and itemizes all work to enable a contractor to price the work for which he or she is bidding.
MBOM is a type of bill of materials (BOM). Unlike engineering bill of materials (EBOM), which is organized with regards to how the product is designed, the MBOM is focused on the parts that are needed to manufacture a product. In addition to the parts list in an EBOM, the MBOM also includes information about how the parts relate to each other.
Applications of TDS measurements are not limited to industrial use; many people use TDS as an indicator of the purity of their drinking water. Additionally, aquarium enthusiasts are concerned with TDS, both for freshwater and salt water aquariums. Many fish and invertebrates require quite narrow parameters for dissolved solids.
A Allocation of costs is the transfer of costs from one cost item to one or more other cost items. Allowance - a value in an estimate to cover the cost of known but not yet fully defined work. As-sold estimate - the estimate which matches the agreed items and price for the project scope. B Basis of estimate (BOE) - a document which describes the scope basis, pricing basis, methods ...
An engineering bill of materials (EBOM) is a type of bill of materials (BOM) reflecting the product as designed by engineering.. The EBOM is not related to modular BOM or configurable BOM (CBOM) concepts, as modular and configurable BOMs are used to reflect selection of items to create saleable end-products.
