2. Reflective surfaces (climate engineering) - Wikipedia

   en.wikipedia.org/wiki/Reflective_surfaces...

   Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface). The IPCC described this method as "whitening roofs, changes in land use management (e.g ...

   It can also calculate material costs and estimates and display results in fractional or decimal forms, area, volume or perimeter functions, weight calculations, roofing, rafter, framing solutions, concrete calculations, complete stair layouts, right-angle functions, circular calculations, building materials estimate: blocks, drywall, footing ...

4. Building estimator - Wikipedia

   en.wikipedia.org/wiki/Building_estimator

   A building estimator or cost estimator is an individual that quantifies the materials, labor, and equipment needed to complete a construction project. Building cost estimating can concern diverse forms of construction from residential properties to hi-rise and civil works. Both estimators and quantity surveyors must have a background education ...

5. Cost estimate - Wikipedia

   en.wikipedia.org/wiki/Cost_estimate

   A cost estimate is the approximation of the cost of a program, project, or operation. The cost estimate is the product of the cost estimating process. The cost estimate has a single total value and may have identifiable component values. A problem with a cost overrun can be avoided with a credible, reliable, and accurate cost estimate.

6. Domestic roof construction - Wikipedia

   en.wikipedia.org/wiki/Domestic_roof_construction

   Ctrs. means centers, a typical line to which carpenters layout framing. Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. [1] Such roofs are built with mostly timber, take a number of different shapes, and are covered with a variety of materials.

7. Quantity take-off - Wikipedia

   en.wikipedia.org/wiki/Quantity_take-off

   Quantity take-off. Quantity take-offs (QTO) are a detailed measurement of materials and labor needed to complete a construction project. They are developed by an estimator during the pre-construction phase. This process includes breaking the project down into smaller and more manageable units that are easier to measure or estimate.
