informationDEFINITIONS :QUALITYis that characteristics of a product that provides a level of performance in terms ofservice & life. It does not mean perfect.PURPOSE:The purpose of materials quality control is to insure the highest quality of work & extend theservice life of any structure by construction according to the prescribed plans & specifications. The plansindicate the specific type of the struc. & the specifications present the characteristic in w/c it is to be built,as well as the matls that are to be incorporated into the work.Other purposes are to check & regulate the use of construction materials, & to economizeon the const of const. Fulfilling these, requires adequate control of materials prior to & after placingto their final position in the structure. The extent of controlling the required materials depends on thenature & limits of the work, the specification requirements & local conditions. Normally, every material shouldbe subjected to testing, inspection & verification before acceptance.PROCEDURES:1Selection of MaterialsInformation regarding the location of matls sources that will be incorporated into the workmay be represented by the following:a.raw matls such as soil, sand & bank or river gravel (w/ little or no processing)b.matls that are processed w/o basically changing their properties, such as washed/manufactured sand, crushed rock & s gravel, etc.c.manufactured matls such as bituminous matls, cement, paint, structural & reinf. steeld.combination of matls that mat be partly or totally manufactured, such as bituminous andportland cement concrete.Materials to be procured or obtained from selected portions of any area of matls sourcessuch asmentioned aboveshould be known in advance so that the required tests can be made orarrangement for testing the matls involved may be done to avoid unnecessary delays in const.due to rejection of unacceptable quality of materials.2Handling & Storage of MaterialsHandling & storage of delivered construction matls should be carefully & properly plannedto avoid damage & maintain the desired quality. It should be palced or deposited in a safeplace protected from contamination or tha action of weather. The proposed source of matls.to be used should be accessible to the project.Conditions for Acceptance of Materials:a.No matls shall be incorporated into the work until tested & found satisfactory.b.The approval of preliminary samples shall not be considered as a guarantee of acceptanceof all matls. from the same source, as to the quality or quantity of such materials.c.Any matls w/c had been sampled & passed as satisfactory may be resampled andretested anytime before, during & after incorporated into the work.3Sampling & Testing of MaterialsQuality Control is cheking for conformity to the requirements. That is, conformance tomatls specifications & methods of const. or workmanship. Quality Control therefore, includesall procedures w/c necessary to ensure that the matls used & workmanship employedconform to the standard of quality specified.a.QUALITY CONTROL PROGRAM(QCP)To facilitate quality control, a program of quality control works to be compliedby the Contractor is prepared by the DPWH. The plan include provisions on how thework & matls should be inspected & the nature & amount of testing to be done.Likewise, the DPWH provides a team to monitor the quuality controlactivities in the project like : sampling, testing, laboratory procedures, equipmentcalibration & quality control reporting.b.Minimum Testing RequirementsAre prescribed in each project based on estimated quantities. Therequirements specify the kind & number of tests for each item of work.Testing is done as the matls are being incorporated into the work. It shouldbe emphasized that what are specified are the minimum number of testing only. Theowner can therefore, can require more test if he is in doubt of the quality of matlsor the finished structure.c.Pretesting of Manufactured Matls such as Cement, Asphalt & Steel Bar.Samples are obtaine at the factory & tested at the laboratories. Uponverification, the pretested matls are ready for use upon delivery at the jobsite.4Proper Construction Methods/Proceduresa.Establish a working quality control organization w/ responsibility for supervision& inspection at all levels of work.b.Construction method should be done according to each Item of Work indicated inthe design.c.To see to it that matls used pass the required specification prior to incoporated tothe project.d.Continnuous quality control inspection on all Items of Work shall be done as constprogressese.To assign technical & capable personnel to oversee the implementation duringconstruction stage.f.To see to it that needed equipment is available.g.To see to it that there is no scarcity of supplies of matls to be used in the project.5Inspection & MonitoringDifferent types of const demand different types & degree of inspection. Emphasison the initial & early operations is essential.Once the equipment & operations are producing the desired quality, occasionalchecking may be done to assure continuous satisfactory results. However, vertical structuresdemand more constant scrunity or verification due to the greater variety of matls & workinvolved. Future results are less predictable on this type of work.Therefore, inspectors assigned in the field should be competent, experienced andcommitted to public service. They should also be familiar w/ the approved plans & specifications& various DPWH issuances relative to quality control & construction.The purpose of inspection is to ensure that the matls & workmanship provided bythe contractor comply w/ the requirements of the project. In general, properly appliedinspection/monitoring the project will help in ensuring that:a.The requirements of the contract documents will be carried out.b.The use of unacceptable substitutes will be avoidedc.Making errors that might result to unnecessary maintenance cost will be avoidedd.Extra work will be minimizede.Materials & workmanship that are guaranteed will be evaluated at the time of installation
