  In Reduced Bearing (RB),  the bearing of a survey line is measured either in a clockwise or anti-clockwise direction from either of the north or south direction whichever is close to the line . The reduced bearing is also known as Quadrantal Bearing System. More Examples on WCB to RB Convert WCB = 35° to RB ·          It is in the First quadrant (NE) ·          Angle = 35° ·          RB = N35°E Convert WCB = 130° to RB ·          It is in the Second quadrant (SE) ·          Angle = 180 - 130° = 50° ·          RB = S50°E Convert WCB = 240° to RB ·          It is in the Third quadrant (SW) ·          Angle = 240° - 180° = 60° ·  ...

  Principle of Compass Surveying   In compass traversing the directions of survey lines are fixed by angular measurements and not by forming a network of triangles.   A compass survey is one in which the traverse work consists of series of lines the lengths and directions of which are measured with a chain or a tape, and with an angular instrument respectively.   A traverse may be classified as: a) Closed traverse b) Open traverse A) Closed traverse:                    A closed traverse is a traverse in which the sides of a traverse form a closed polygon.   B) Open traverse:                    An open traverse is a traverse in which the sides of traverse do not form a closed polygon. Included angle method:          ...

  CONSTRUCTION ENGINEERS GUIDE TO TMT REINFORCEMENT BARS QUALITY CONTROL CIVIL SITE ENGINEERS GUIDE TO TMT QUALITY CONTROL In any reinforced concrete (RCC) construction, two critical components are TMT Rebar and concrete. The lifespan and safety of such structures heavily rely on the quality of these Rebars and Concrete. Designers and engineers should only approve TMT Rebars after thorough testing and verification, regardless of the manufacturer’s name. The first way to check the quality of reinforcement is to check it mechanical properties. Mechanical testing serves two primary purposes: 1.                  Providing design data and 2.                  Ensuring a structure’s ability to withstand specific stress limits without failure. For instance, the tensile test can determine the yield strength of steel f...

  THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS   The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the worl...

  What is Fore Bearing and Back Bearing in Surveying? A fore bearing is the measurement of the direction from one station to the immediately adjacent next station along a traverse.  In contrast, a back bearing is the measurement of the direction from one station to the immediately adjacent previous station, but in the opposite direction to the traverse.  It's important to note that the fore bearing and back bearing of a line will always have a 180° difference between them.

  Whole Circle Bearing (WCB) Bearings are measured clockwise from north of reference meridian . ·          It varies from 0 degrees to 360 degrees in the clockwise direction ·          North will be zero degrees; East will be 90 degrees; South will be 180 degrees and West will be 270 degrees. ·          Prismatic compass uses the WCB system Reduced Bearing (RB ) Bearings are measured either clockwise/anti-clockwise from north/south whichever is close to the line. ​ It is also known as Quadrantal Bearing (QB) Angles vary from 0 degrees to 90 degrees It is measured from either clockwise/anti-clockwise from north/south Four quadrants are possible namely NE, SE, SW and NW Surveyor's compass used RB system.

  Elevate Your Safety IQ: Tips for Secure Workplace Practices Workplace safety is more than a regulatory requirement. The safety and well-being of employees are of critical importance, which is why this blog explores the pivotal role of Safety IQ in preventing incidents and offers essential workplace safety guidance for employers and employees. Importance of Workplace Safety: Workplace safety is critical for any organisation, regardless of its industry or sector. The importance of workplace safety can be understood through the following key points: 1.                   Protection of Human Lives: The primary and most significant reason for workplace safety is the protection of human lives. In a working environment, employees face various hazards and risks daily. Establishing  safety measures  helps prevent accidents and injuries, ultimately saving lives. 2.    ...
