However, the review process can delay the construction process. To this end, shop drawings and samples should only be requested if there is a real need for the designer to confirm design intent. For example, the designer may not need to review shop drawings for simple joinery.  \nSHOP DRAWINGS AND SAMPLES IN NATSPEC  \nMany NATSPEC worksections require the submission of samples and/or shop drawings.  \nPrompts for the submission and review procedure for samples and shop drawings are included in the 0171 General requirements , SUBMISSIONS AND INSPECTIONS, SUBMISSIONS clause where the following issues are addressed:  \n• To whom the submissions are tobe made e.g. architect in ABIC contracts.  \n• The requirement to program the submissions. Specifiers may wish to include a requirement for ashop drawings/sample submission schedule co-ordinated with the general construction program.  \n• The form of the submissions. Submission requirements for samples and shop drawings are set out in the SUBMISSIONS clause of the various technical worksection Templates. Detailed requirements vary depending upon the nature of the item. Edit or delete the default requirements to suit the project.  \nSAMPLE SUBMISSION AND APPROVAL PROCESS  \nSamples are commonly required for joints and sections, products and components and specified proprietary items to verify characteristics such as profile, surface finish and colour range. To achieve the required outcomes, the submission and review of samples should address the following issues.  \nSize of samples  \nIf samples of materials such as natural stone are required, samples must be of sufficient size to represent  \nthe range of the characteristics of the material e.g. a stone sample size of 150 x 150 mm may be inadequate to fully indicate the range of the stone characteristics. If the required item has a range of characteristics, multiple samples may be required. The submission of at least two samples may be required for each item. Edit the worksection as required.  \nSample approval process  \nNATSPEC, as a generic technical specification system , does not contain management systems to handle the approval process. If an approval is required before implementation, consider nominating a Hold point, to eliminate ambiguity. Consider documenting approval criteria and the acceptance procedure.  \nStorage of samples  \nFollowing review and approval of samples, each sample should be tagged for identification purposes. One sample is retained off-site by the contract administrator, and one sample is retained on-site in a secure place. Samples have an unfortunate habit of disappearing during the construction period and it may be useful to photograph samples to safeguard the selection in event of loss. Consider documenting a procedure for acceptance criteria and storage.  \nIncorporation of samples  \nThe submission of samples can be costly. 0171 General requirements makes provision for the incorporation of samples which conform to the contract into the works, to avoid wastage. NATSPEC Preliminaries worksections require the removal of non-incorporated samples before the date for practical completion.  \nDEFINITIONS Shop drawings  \nA drawing required by a construction contract to be submitted to the contract administrator for review for conformance with design intent. The content is the responsibility of the contractor. Shop drawings do not form part of the contract set.  \nSample  \nA physical example that illustrates a product’s workmanship, materials, or equipment and establish standards by which the work will be judged. It includes samples and sample panels.  \nPrototype  \nA full size mock-up of components, systems or elements to demonstrate or test construction methods, junctions and finishes, and to define t","cbCaik3rGVNBCptu","https://ap.wps.com/l/cbCaik3rGVNBCptu","pdf",162722,"English","# Introduction\n# Shop drawings and samples in NATSPEC\n# Sample submission and approval process\n## Size of samples\n## Sample approval process\n## Storage of samples\n## Incorporation of samples\n# Definitions\n# Relevant worksection\n## 0171 General requirements\n## Shop drawing submission and review process\n### Contractor’s responsibility\n### Shop drawing schedule and program\n### Format of submissions\n### Information to be shown on shop drawings","[{\"question\":\"Why should shop drawings and samples be requested only when there is a real need?\",\"answer\":\"They can delay construction because the review process takes time.
