QAQC in Construction

  Procurement management follows a logical order. First, you plan what you need to contract; then you plan how you’ll do it. Next, you send out your contract requirements to sellers. They bid for the chance to work with you. You pick the best one, and then you sign the contract with them. Once the work begins, you monitor it to make sure that the contract is being followed. When the work is done, you close out the contract and fill out all the paperwork. You need to start with a plan for the whole project. Before doing anything else, you need to think about all of the work that you will contract out for your project. You will want to plan for any purchases and acquisitions. Here’s where you take a close look at your needs to be sure that contracting is necessary. You figure out what kinds of contracts make sense for your project, and you try to define all of the parts of the project that will be contracted out. Contract planning is where you plan out each individual contr...

Concrete mix design is a method of calculating the right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures. The Concrete mix design Concrete Mix = Cement:Sand:Aggregates. There are two Methods Volume Batching Weigh Batching For a mix design of concrete, we have to follow various steps, calculations, and laboratory testing to find the right mix proportions. M20 (1 cement :1.5 sand :3 stone/brick aggregate). To determine the proportions you have to perform mix design, you have to find out the Specific Gravity  of cement, CA, FA, and water-cement ratio, type of exposure, Maximum size of aggregate, etc. Once the W/C ratio is determined use 186 kg water (for 20mm CA) to find out the qty. of cement per cum of concrete. Then determine the qty. of FA and CA with the help of the formula given in IS:10262-1982, and then divide all the ingredients by cement, then you will get the proportion similar to you mentioned which are in kg. Or you can fo...

This Method Statement for the Construction of Fibreglass Manhole and Appurtenances is the systematic procedure in safely performing the detailed installation of precast manholes and appurtenances ensuring that quality control objectives are maintained. This method statement also covers, in brief, the installation procedure concerning approved shop drawings, design drawings, manufacturer recommendations, and following project specifications. Execution is not limited to the following scope of wor ks and varies as the construction of manhole advances to the finishing stage which includes: Survey Trench Excavation Installation of Permeable Geo-textile Installation of Underground HDPE Perforated Pipes Construction of Manhole Chambers and Bases Installation of Manhole Benching Backfilling The method statement provides guidance for assessing the activities i.e. transportation, handling storage, site preparation, installation, and inspection. This guidance is based on the requirements outline...
