Effectively control engineering construction and eliminate material waste?

how to effectively control the project construction and put an end to the waste of materials? Here, the bidding teacher of Zhongda Consulting will answer your questions for your reference.

for engineering construction, materials are an indispensable factor, but in actual construction, due to the lack of construction technology and experience of the construction team, materials are often wasted. Material waste is the key to ensure the expected profit of the whole project. Therefore, in actual construction, we should pay attention to excessive material consumption to avoid material waste, and take appropriate measures to strengthen material management and reduce material consumption. The following is a summary of the key points for attention in the management of engineering materials, hoping to provide you with reference.

key points of material management

1 before construction, determine all the parameter data of the drawings, such as the brand, model, specification, fidelity and deviation of the equipment, as well as the relevant parameters of spare substitute products, and prepare the corresponding material plan, indicating the management, use and consumption assessment of materials.

2 we should determine the material purchasing plan in advance, conduct market research, make reasonable selection, and control the material price by comparing with many material suppliers.

3 materials shall be inspected before entering the site, and shall be accepted and put into storage only after passing the inspection and meeting the requirements of design and corresponding current standards.

4 set up special material management personnel to supervise and inspect the use of various materials in the construction process, and urge the unit to deal with the phenomenon of littering on the construction site.

5 materials should be stored under suitable environment and protective conditions, and warehouse keepers should be set up to regularly check the storage of materials in the warehouse to ensure the normal quality and turnover of materials in the warehouse. At the same time, the stored materials should be used within the service life.

6 materials that are not used at the construction site for the time being must be stacked in the position specified in the general plan, and they should be stacked neatly, so as to facilitate transportation, loading and unloading and reduce secondary handling.

7 To fully recycle and utilize all kinds of wastes during construction, we can set up garbage sorting stations to carry out timely sorting, recycling and utilization.

prevention and control measures for waste of engineering materials.

concrete engineering

(1) The slump of concrete is detected and recorded, so as to prevent pump blockage caused by too small slump and concrete waste.

(2) When pouring the beam around the flat plate and the side span, pump the concrete to a position 1m away from the inner surface of the beam, and then spread the concrete to the surrounding position manually, so as to prevent the concrete from spilling. In case of spilling, the spilled concrete can be recycled in time.

(3) The joint position at the bottom of the wall and column should be caulked in advance to avoid large slurry leakage during concrete pouring, thus affecting the quality of structural joints.

rebar engineering

(1) rebar production must be processed in batches, each batch should be a construction section not less than 3m long, and it is not allowed to tie the components one by one, so as not to affect the progress of the project, or cause a lot of waste of materials and serious slowdown.

(2) After construction, all steel bar heads shall be cleaned and classified according to the thickness and length, and they shall be placed with one end aligned. At the same time, the steel bar heads and the remaining semi-finished steel bars shall be registered, which will provide a basis for the selection of materials for the next time.

(3) Before the steel bar is cut, it must be selected and used in the material head, and the raw steel bar can only be used when there is no material head available.

masonry engineering

(1) Choose suitable cement varieties and strength grades, and try to use aggregate with large particle size under the same grading.

(2) The product age of brick, stone and other materials used in masonry engineering should meet the specification requirements, so as to control the occurrence of shrinkage cracks in materials during construction, ensure the strength of the structure, and thus avoid rework and waste.

(3) The broken and cut half brick should be fully and reasonably utilized, and it should be used in the construction of top brick masonry and other special parts after re-cutting.
