Similarly, for a reinforced concrete beam, the measurement of formwork will be taken as the combined surface area of two sides and bottom of the beam. Issues in Formwork Measurements: Normally, the forms are used more than once in concrete construction. But the payment is calculated based on the total contact area of the formwork with concrete and reuse of the forms is not taken into account. Thus, the price per unit area of formwork can be reduced for reuse of the forms. Aluminium and steel forms are reused for many number of times than wooden forms. Complicated shape of concrete makes the formwork installation costlier than the simple formwork installation because of labor cost and inability to reuse these forms. A construction plan is required to reuse the forms maximum number of times to make the construction cost effective. Deduction of formwork area should not be taken for: Intersection of beams Intersection of beams and columns and walls Any openings or cutouts in slabs Unit of Formwork Measurement: Formworks are measured in terms of area. So any unit such as square meter, square foot, square centimetre can be adopted. But generally, square meter and square foot of the contact area with concrete is taken as the unit of measurement. The dimensions of a formwork should be measure correct to the centimetre or inches whichever the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
