FDD stands for Field Density Test. Loose soil density ranges from 1.2 to 1.4 g/cm³ and compacted soil density ranges from 1.4 to 1.6 g/cm³.

• FDD is a test used to determine the density of soil in the field.

• Loose soil density ranges from 1.2 to 1.4 g/cm³.

• Compacted soil density ranges from 1.4 to 1.6 g/cm³.

• The density of soil affects its strength and load-bearing capacity.

• The density of soil can be increased through compaction techniques such as tamping or rolling.

• It also covers the calculation of cutting length, development length, and lap length of reinforcement...read more

CA stands for Contract Administration. There are typically 3 schedules in a construction contract.

• CA involves managing and enforcing the terms of a construction contract.

• The 3 schedules in a construction contract are typically: Schedule of Values, Payment Schedule, and Change Order Schedule.

• The Schedule of Values outlines the budget for the project, the Payment Schedule outlines when payments will be made, and the Change Order Schedule outlines the process for making changes ...read more

OGL Sampling stands for OpenGL Sampling. It is a technique used to improve the quality of graphics rendering in computer graphics.

• OGL Sampling is used to reduce aliasing and improve the quality of graphics.

• It involves taking multiple samples of a pixel and averaging the color values to produce a smoother image.

• The number of samples taken per pixel can be adjusted to balance quality and performance.

• OGL Sampling is commonly used in video games and other real-time graphics appli...read more

EPC Contract stands for Engineering, Procurement, and Construction Contract.

• EPC Contract is a type of construction contract where the contractor is responsible for the entire project from design to construction.

• The contractor is responsible for the engineering, procurement, and construction of the project.

• EPC Contracts are commonly used in large-scale infrastructure projects such as power plants, oil refineries, and highways.

• The contractor is responsible for delivering the pr...read more

Overlapping can be monitored by using software tools that can detect and highlight overlapping areas.

• Use software tools like AutoCAD, Revit, or Navisworks to detect overlapping elements

• Check for clashes between different systems like mechanical, electrical, and plumbing

• Perform regular clash detection tests during the design and construction phases

• Ensure that all stakeholders are aware of the overlapping issues and work together to resolve them

Software used for quantity calculation includes AutoCAD, Revit, Bluebeam, PlanSwift, and On-Screen Takeoff.

• AutoCAD is a popular software for 2D and 3D design and drafting

• Revit is a BIM software used for building design and construction

• Bluebeam is a PDF software with measurement tools for estimating

• PlanSwift is a takeoff and estimating software for construction
