21、 permeationa process in which water enters, flows, and spreads within and discharges from a material.4. Significance and Use4.1 This guide is intended to provide building professionals with a comprehensive methodology for evaluating water leakagethrough walls. It addresses the performance expectatio

22、ns and service history of a wall, the various components of a wall, and theinteraction between these components and adjacent construction. It is not intended as a construction quality control procedure, noras a preconstruction qualification procedure. It is intended for evaluating buildings that exh

23、ibit water leakage.4.1.1 QualificationsUse of this This guide requires the evaluator to possess a knowledge of basic physics and ofconstruction and wall design principles and practices.4.1.2 ApplicationThe sequential activities described herein are intended to produce a complete and comprehensive ev

24、aluationprogram, but all activities may not be applicable or necessary for a particular evaluation program. It is the responsibility of theprofessional using this guide to determine the activities and sequence necessary to properly perform an appropriate leakageevaluation for a specific building.4.1

25、.3 Preliminary AssessmentA preliminary assessment may indicate that water leakage problems are limited to a specificelement or portion of a wall. The evaluation of causes may likewise be limited in scope, and the procedures recommended hereinabridged according to the professional judgement of the in

26、vestigator. A statement stipulating the limits of the investigation shouldbe included in the report. A preliminary assessment may indicate that water leakage problems are limited to a specific elementor portion of a wall. The preliminary assessment may also indicate that the wall is not the source o

27、f a leak even though it isperceived as such by the building occupant. The presence of water might result from a roofing problem, a condensation problem,a plumbing problem, operable windows or doors left opened or unlatched or some other condition not directly related to waterleakage through the buil

28、ding wall and is outside the scope of this guide. The evaluation of causes may likewise be limited in scope,and the procedures recommended herein abridged according to the professional judgement of the evaluator.Astatement stipulatingthe limits of the investigation should be included in the report.4

29、.1.4 ExpectationsExpectations about the overall effectiveness of an evaluation program must be reasonable and in proportionto a defined scope of work and the effort and resources applied to the task. The objective is to be as comprehensive as possiblewithin a defined scope of work. The methodology i

30、n this guide is intended to address intrinsic leakage behavior properties of awall system, leading to conclusions that generally apply to similar locations on the building. Since every possible location is notincluded in an evaluation program, it is probable that every leak source will not be identi

31、fied. Leakage sources that are localizedand unique may remain and may require additional localized evaluation effort. The potential results and benefits of the evaluationprogram should not be over-represented.4.2 This guide is not intended as a design guide or as a guide specification. Reference is

32、made to design features of a wall onlyfor the purpose of identifying items of interest for consideration in the evaluation process.4.3 This guide does not address leakage through roofs, leakage below grade, or water that accumulates due to water vapormigration and condensation. It is not intended fo

33、r use with structures designed to retain water, such as pools and fountains.SYSTEMATIC APPROACH TO AN EVALUATION5. Overview5.1 The methodology presented in this guide is a systematic approach to evaluating wall leaks and is applicable to any wallsystem or material. It differs from other approaches t

34、hat are material specific or component specific and which are basicallyadaptations of quality control procedures. The sequence of activities is intended to lead to an accumulation of information in anorderly and efficient manner, so that each step enhances and supplements the information gathered in

35、 the preceding step.5.1.1 Sequence of ActivitiesThe recommended sequence of activities, discussed in individual sections below, are:5.1.1.1 Review of project documents.5.1.1.2 Evaluation of design concept.5.1.1.3 Determination of service history.5.1.1.4 Inspection.5.1.1.5 Investigative testing.E2128

36、 1225.1.1.6 Analysis.5.1.1.7 Report preparation.5.25.1.2 The first four recommended activities, and their descriptions in the body of the guide, are: 6. Review of ProjectDocuments; 7. Evaluation of Design Concept; 8. Determination of Service History; and 9. Inspection. These activities intentionally

37、precede 10. Investigative Testing because they facilitate a rational determination of the spectrum of conditions, and are the basisfor a rational selection of investigative test locations and procedures.5.2 The protocol in this guide is not based on conventional hypothesis testing and quantitative r

38、andom sampling.4The startingpremise for the application of this guide is that the building is suspected or known to leak. The objective of this guide is qualitative,purposeful, and intended to address the question of why, how and to what extent a building leaks.Astatement stipulating the limitsof th

39、e investigation and the starting premise of the investigative program should be included in the report.5.3 Scope of InvestigationIt is not assumed or expected that all locations with similar design, construction and servicecharacteristics will be currently performing in precisely the same manner. Li

40、kewise, it is not necessary to establish such in orderto reach technically valid conclusions about why and how a building leaks. The evaluation of water leakage of building walls isa cognitive process in which technically valid conclusions are reached by the application of knowledge, experience and

41、a rationalmethodology to determine the following:5.3.1 The intrinsic properties of the wall.5.3.2 The cause(s) and mechanism(s) of leakage.5.3.3 The applicability of findings to similar un-inspected or un-tested locations on the building.5.3.4 And, if within the scope of the evaluation, to acquire a

42、nd report sufficient information to permit an assessment, within areasonable degree of scientific certainty, of the likelihood of additional water leakage to occur arising from the conditions identifiedand the conclusions reached as a result of the evaluation.5.4 SamplingThe recommended sampling met

43、hod for the application of this guide is to consider the spectrum of wallconditions from apparently performing to apparently non-performing areas, and from un-deteriorated or un-damaged areas todeteriorated or damaged areas. It is also important to distinguish between varying conditions which may re

44、sult from priormodifications or attempted repairs, and to determine the extent of sampling necessary to address and evaluate these variations inconditions.5.5 Analysis and InterpretationThe information systematically gathered during a leakage evaluation is analyzed as it isacquired. The sequential a

45、ctivities described in this guide are not intended to imply that analysis and interpretation of theinformation occurs only at the completion of all activities.6. Review of Project Documents6.1 Ideally, project documents including wall component shop drawings will be available and accessible for revi

46、ew. Thediscussion in this section assumes that a project was organized on a conventional Owner/Architect/Contractor model. Buildingprojects can be delivered in a variety of ways, and the actual method used will dictate the appropriate organization of the projectdocuments. Regardless of how a project

47、 is organized and administered, the information discussed below should be available forreview somewhere in the project documents.6.1.1 Design, Bidding, and Contract DocumentsThese documents include architectural and engineering drawings andspecifications and may also include calculations, wind tunne

48、l reports, correspondence, meeting minutes, addenda, substitutionproposals, product literature, test reports, etc. They contain the information necessary to understand the performance criteria, thedesign intent, the required materials, and relationships among wall components.6.1.1.1 Documents may be

49、 revised or supplemented over the course of construction. Revisions to drawings are typicallyrecorded by number and date with a cross reference to other accompanying documents. Reviewing all revisions and issuances ofthe documents, and understanding the differences between them and the reason for the differences, is part of a comprehensiveevaluation.6.1.1.2 Documents with the most recent issue date and the highest revision number establish the requirements for the project.Ideally, a set of documents marked “as-built” or “record set” intended to show the actual co
