QAQC in Construction

SAMPLE JOB DESCRIPTION (QA/QC Manager) Description The QA/QC Manager is responsible for ensuring that the quality management system (QMS) is fully implemented in an organized and efficient manner. The QA/QC Manager is responsible for delegating and assigning tasks to QA/QC Supervisors and working closely with related engineering, construction, fabrication, and repair departments. Duties and Responsibilities Manage and oversee project quality to ensure compliance to codes, standards, regulations, equipment specific specifications, and QMS requirements. Advancing quality achievement and performance improvement throughout the organization. Managing the development and implementation of the QMS for planning, fabrication, inspection, documentation, and operations activities including: Planning duties within the QA/QC staff and related work schedules; Establishing service standards for end users (i.e., internal department or external customer); Identifying and developing Q...

If you are a Civil Engineer or a Quality Engineer and you are new to the field of construction and guess why? I am writing this because I am going to show you, what are the tests to be applied in the particular activity on your ongoing project. There are various tests needed in different areas of site activities whether it is in infrastructure or building projects. Infrastructure projects like road, embankment, bridge, viaduct, tunnel, dam etc. In the building project, it has common test that normally done which I will show in the foregoing paragraph. So let us proceed with the following different types of test in different areas of your site. On Infrastructure & Road projects When I was in the City Engineering Department in my home country. Our projects there were roads, bridge, school buildings, public market, coliseum, park but most of the projects I attended were roads like 8 kilometers long and the longest is 15 km including drainage and box-culvert. Here are the t...

This is a continuation of the previous article I posted How to do a compaction test or In-situ density test, about calculation of the test report. Here we are going to compute the bulk density of sand down to the  degree of compaction  of soil. I would really want to pursue this article just to completely show the full process of getting the results of test from taking the samples into calculations. So every site engineer, project engineer, and consultant inspector, as well as engineering students should know how it is done. This would be a guide and help them learn the procedures. Here are the steps of calculations to determine the compaction test or In-situ density test report. 1. Compute the Bulk Density of sand. The calculation of bulk density of sand shall be made in the laboratory before moving on to the site. Here are the values tabulated below. Values taken from the laboratory V 0.00785 m³ Volume of calibrating container M1 17,050 gm Mas...

SOIL COMPACTION TESTS The main  differences between  the Soil  Compaction and the Consolidation  process are given below.  Compaction  is a process where mechanical pressure is used to compress the soil mass for the purpose of soil improvement.  Compaction is a  process  of increasing soil density and removing air, usually by mechanical means. The size of the individual soil particles does not change, neither is water removed. Purposeful compaction is intended to improve the strength and stiffness of soil.  In the consolidation  process, soil volume is reduced by squeezing out pore water from the saturated soil. TYPES OF COMPACTION: DEEP COMPACTION:  Dynamic compaction  is a method that is used to increase the density of the soil when certain subsurface constraints make other methods inappropriate. ... The process involves dropping a heavyweight repeatedly on the ground at regularly spaced intervals. SHALL...
