Practicing the "three basics" well includes: improving the skills of looking at pictures; Familiar with common standard drawing methods; Familiar with the calculation rules of engineering quantity and so on.

First, improve the skills of looking at pictures

Before calculating the engineering quantity, you should browse the whole set of drawings from beginning to end, and then choose to look at the drawings in detail after you have a general understanding of its design intention. In the process of looking at pictures, we should focus on the following issues:

(1) architectural drawings

1, know the number and height of buildings (including height and total height), indoor and outdoor height difference, structural form, total longitudinal length and span, etc.

2, understand the engineering materials and practices, including the floor, roof, doors and windows, wall cylindrical decorative materials and methods.

3. Understand whether the wall thickness, floor, doors, windows, ceilings and interior wall finishes of buildings have changed on different floors (including changes in material practices, sizes and quantities), so as to adopt different calculation methods.

(2) Structure diagram part

1, understand the foundation form, depth, soil type, excavation method (determined according to the construction plan) and materials and practices of foundation and wall.

2. Understand the relevant contents involved in the calculation of quantities in the structural design description, including the types and strength grades of masonry mortar, the concrete strength grades of cast-in-place components and prefabricated components, and the anchorage and lap joint provisions of steel bars. , so as to fully understand the design intent of the drawings and avoid recalculation or omission.

3, understand the plane layout of the component and the index position of the node diagram, so as to avoid rummaging through the drawings during calculation and wasting time.

4. For the brick-concrete structure, it is necessary to find out how much the section height of the ring beam is distributed in those parts of the wall, what changes have been made in the section of the ring beam at the balcony, doors and windows, and whether the width of the ring beam inside and outside the wall is consistent, so that when calculating the volume of the ring beam, it can be calculated in sections according to different widths.

5. For buildings with overhangs, balconies and awnings, it is necessary to understand the connection relationship between cantilever components and intersecting coupling beams or ring beams, so as to know fairly well when calculating.
