Some of the advantages of digitization are perpetual preservation of vulnerable physical documents, quick and easy retrieval, easy access and easy to share.
All original records must be examined for their digitization suitability prior to the digitization process. This process will determine the extent of preparation required and ensure that successful images are obtained from the digitization process.
E-Tools is a generic term, which covers usage of a combination of computer hardware, software, communication tools and technolooies for. Key beneflts of E-Tools are: Project. These are written in form of various steps in a particular sequence supplemented by suitable sketches to be self-explanatory.
These method. Better quality, speed and effective flow of information. Builds transparency and accountability at all levels. These records will enable preparation of the completion report as well as investigation of 9. During the course of DPR preparation, several discussions are made at site as well as office, v Non-conforming Products: Detailed statements have to be prepared which impact different aspects of the project. Reports, lA plans submitted by the Consultant shall be maintained at the site office of Authority.
For the quality of the finished work, it is necessary for the materials and workmanship to fully comply with the work requirement.
Receiving ofllcer to whom documents are issued at site should maintain personnel to perform such audits and define the frequency and procedure similar record. The method of reporting the findings and recommendations and the ii Inspection Proforma: These are used for the purpose of seeking approvals means for corrective actions shall be documented.
These are usually supplemented by standard checklists which approvals, tratfic diversion, safety and environmental safeguards measures have to be verified by the 'Engineer'and after he is satisfied about contents, etc. The Proforma are usually maintained in two forms - one for The conditions of Contracvconcession Agreement provide all information recording the observations during each test and calculation of quality and the required content of "As-built Drawings", and responsibilities for their characteristics.
The second is for recording the summary of test results to preparation. The Engineer must supervise, monitor, and check iv Method Statements: The method statements give a detailed proposal the preparation of the As-built Drawings. The preparation of these drawings of the constructing agency for carrying out each and every activity in the must be performed during the course of the works and must not be left until. The authenticated documents should v, be kept under the safe custody of site offlce ofAuthority after completion of the work.

Plant Machine Type Model No. Manufacturer Manufacturer date Prior to second decade of 20h century industrial quality control meant inspection of products and removing defective ones. Shewhart started the process Control whlle workino in Western Electric Company jn the year and further developed it when he moved to Eell General Conditions Laboratories.
A physicist, engineer and statistician by profession, Dr. Shewhart framed the problem in terms of assignable-cause and chance-cause varjation and Overall Appearance introduced the control chart as a toolfor distinguishing between the two.
Apart from Environmental Condition his statistical prowess,it was Deming's philosophy to manage a,,system" to achieve a high quality product or service that resulted in the grand success of Japanese manufacturing Specifi cation Requirements industry Deming's chain reaction is given below: Spec. Clause No. The next step foMard in quality management is six-sigma A six sigma process is one in which Because ofthe proDerties Date: Date uate of the normal distribution, values lying that far away from the mean are extremely unlikely: approximately 1 in a billion too low, and the same too high.
This is Sample Space: In probability theory, the Sample Space of an experiment or random trial is why Six Sigma aims to have processes where the mean is at least 60 away from the nearest the set of all possible outcomes or results of that experiment. Random Sampling: Random Sample is a subset of a statistical population Lot in which Speciflc managementtools are employed in allthe 3 methods mentioned above by monitoring each member of the subset has an equal probability of being chosen.
A simple Random certain statistical parameters in different stages of manufacturing. Sample is meant to be an unbiased represenlation of the Lot. The process of selecting a 1O. Variability occurs in materials and processes used for road Mean: Mean refer to a measure of the central tendency either of a probability Distribution or construction. Limiting the variability is a prime objective of QA Plan but variability does exist and needs Variance: Variance measures how far a set of numbers is spread out.
The variance of a Random VariableX is the expected value of the squared deviation from the Mean. Adding to the variability of materials and processes, there Standard Deviation; Standard Deviation SD, also represented by the creek letter sigma is also considerable variation in the process of sampling of materials carried out for testing o or s is a measure that is used to quantify the amount of variation or dispersion of a set of and actual testing of materials resulting in measurement errors.
Under such circumstances, data values. The standard Deviation of a Random variable, statisticar population, data set, statistical analysis helps in taking informed decisions about acceptance. While the guidelines or Probability Distribution is the square root of its Variance.
Essentially, statistical quality control called a continuous Probability Distribution. Leave a Reply Cancel reply Enter your comment here Fill in your details below or click an icon to log in:.

Usually performance of similar existing works is the best guide for finalizing the design of new works. KRamana Reddy. To facilitate inspection minimum vent height of culverts and carrying out repairs, the should normally be mm. Culverts of small span or diameter are found to get choked due to silting and also cause difficulty in cleaning. The procedure described above can be applied if either the slope of the stream or the actual observed velocity is known. Only written dimensions are to be followed.
