## Standard Dimensions For Stairs

Today we are going to present you every piece of a staircase with the proper size for each of them. These specs will help you build a safe, comfortable set of stairs for most houses. The tread is the horizontal section of each stair, sometimes called the run. This is the part you step on.Thread depth is the place between […]

## Strengthening A Three-story R/C Building Process

It is becoming preferable, both environmentally and economically, to upgrade building structures rather than to demolish them and rebuild them. On the pictures below is shown a construction of the strengthening interventions of a three-story reinforced concrete building in Glyfada, Athens. This project involved increasing of 66 R/C columns their cross-sections with the application of new […]

Just follow mason’s instructions in this video and he will show you how to achieve the half round arch for front door steps. He marks the curve by rotating a stick and laying down bricks at the edge of […]

## 9 General Points For Calculation Of Reinforcement

We are going to discus about 9 important points you should consider when you make reinforcement estimate. Estimation of steel reinforcement quantity is required for calculating cost of RCC structure along with other building materials as per construction drawing. For perfect estimates for reinforcement, consider the following points : 1. For beam hook= (beam depth – […]

Construction cost estimating is the process of forecasting the cost of building a physical structure. Here we will give you estimates in building construction sample spreadsheet to determine a project’s scope and feasibility and to allocate budgets.This estimate shows required materials, labor, time to complete the project, complete cost details and overhead and also contractor […]

## Important Surface Area Formulas

Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single […]
