FOREWORDImaginebeingtaskedwithsupervisingtheconstructionofanewcity,erectingmorethan1.5 million square meters of designed spaces. Added to this is the responsibility ofensuring complex technologies are appropriately embedded throughout the manycomplicated structures, all requiring compliance with strict quality standards. Such aproject existed, named the King Khalid Medical City (KKMC), located in Dammam,KingdomofSaudiArabia,andthisbookwaswritteninpreparationforthatproject.
The size and scopeof the project give a fair indicationof the complexity involved andeffort required.TheKKMCprojectwasvalued in thebillionsof dollars, and the scopeincludedtheconstructionofmanyparts:
mainhospitalbuildingwithlatestmedicalservices administrationwingwithtrainingfacilitiesandconferencecentre staffandvisitorresidentialtowerbuildings communitycentrewithmosque multi-storeyc arpark linked to themainhospitalbuilding, administrationwing, and residential
towers.
Themanypartsoftheconstructionscopeandultimatelythecity,likemostothersimilarprojects,hadafast-trackprogrammeand,thereby,arapidlyapproachingcompletiondate.Substantialupfrontplanningwasthereforerequired,notonlytoensureresourceswereinplaceandactivitieswereappropriatelyscheduled,butalsotoensurethatprocesseswereinplaceastohowdataandinformationwastobemanaged.Onceworkstarted,itwouldbedifficult to manage any change, considering that a continued focused effort would berequiredtoensurewhatwasdoneandhowitwasdonewereinaccordancetospecificationand,mostimportantly,toensureerrorswereminimisedandreworkanddelaysavoided.
Key to monitoring and controlling construction works is the role of the constructionsupervisor. The construction supervisor (or CS as referred to in the book) is often anindependent third party who is appointed to verify works, confirm what is done is inaccordancewithcontractrequirements,andensurethatthespecifiedoutputsareachieved.As explained in this book, construction supervision becomesmost effective when it isappropriatelyinterfacedandsyncedwithbothsiteactivitiesandmanagementoversightasthis provides themeans tomake effective andongoingperformancedecisionsbasedonwhat is occurring on-site. And with effective decision-making, the work effort can bedirectedtowardsdoingtherightthingsattherighttime.
The construction supervision practices and methodology outlined in this book are
-
applicable toboth the consultant and contractor as both are taskedwith supervising theworks undertaken. This book details how the supervision role could be planned andutilised,listingthemanyaspectsthatshouldbeconsideredasconstructionworksproceedsandastheyarecompleted.Itprovidesusefulreferenceswithachecklistofwhatneedstobe done along each step and phase of the construction path, from pre-construction tocommissioningofcompletedworksandpost-constructionorclosingphase.Italsooutlineswhat raw data to be collected from site activities; how it should be processed,interpreted,interrogated;andhowitshouldbeusedtoassessworkperformance,therebymakingappropriate informeddecisions.Constructionsupervision is,afterall,a role thatoversees constructionworks inorder to ensure the right things aredone to the requiredstandard and, where required, also provide the means to make timely informedinformationthatcanensuretherequiredperformanceisachieved.

CHAPTER1
ProjectManagementinConstructionAproject is a temporary endeavour that is used to create a unique product, service, orresultwithinasetperiod. Ithasabeginning that isestablishedbyasetcommencementdateandhasadefinitiveendthat isreachedwhenall requiredworksarecompletedandtheoutcomeemerges.Projectmanagement is theprocess that ensures theprojectworksoccurefficiently,anditisadisciplinethatemploys
certain management tools that facilitate the delivery of the project outcome. Themanagementtools,asdefinedbyPMI,includetheprocessgroups,whichareasInitiation,Planning, Executing, Monitoring and controlling, and Closing phases (abbreviated toIPEMC), and the knowledge areas, which are the Quality, Scope, Time, Cost,Communications, HR, Risks, Integration, Procurement, and Stakeholder managementaspects(abbreviatedtoQ-STC-CHRIPS).
Understanding both the IPEMC processes and Q-STC-CHRIPS knowledge areas isimportant as theseprovide themeans to effectivelymanageprojectworks.The IPEMCprocesses, in essence, relate toW.EdwardDemings Start, Plan,Do,Check, andAct(withtheadditionofanendprocess),andcanbesummarisedintothefollowingphases:
phase 1: initiation, the start, where resources are mobilised to commence theprojectworksandwheretheworksisplanned
phase2:executingandmonitoring,thedo-check-actpartoftheworks phase3:closingorendingtheworksand,thereby,theproject.
The initiation phase refers to project start-up activities, where decisions are made toundertaketheworksandmobilisekeyresourcestocommencetheworks.Onceinitiationactivitiesarecompleted, theprojectmoves to theplanningstage,where it isdeterminedhowbest toexecute theworks.As theplan isexecutedandworkcommences, then it isimportant tomonitor theworks andensure these areundertakenasplanned soprogressremainsasperscheduleinaccordancewithpre-establishedbaseline.
The planned outcomemust also be structured to anticipate the possibility of issues andchangesarisingwithrespecttotheQ-STC(quality,scope,time,andcosts)aspectsoftheworks.Thisrequiresthemonitoringprocessestoincorporatedataevaluationprocessessothe data gathered can be systematically assessed, understood, and appropriate decisionsmade. Similarly,whenmajor changes are contemplated or required, then theremust besufficiently robustprocesses inplace that allow theworks (orpartsof theworks) tobereplanned,altered,oradjustedalongwiththebaseline.Insuchinstance,afurtheranalysis

Asconstructionworksnearcompletion, theprojectmovesinto theclosingphase,wherethe focus is shifted to commissioningand readyingequipment andplant foroperationaluse, completing outstanding works and omissions, and rectifying defects. Once themajority of these are completed and the client accepts the works, then the post-constructionperiodcommences.Thisisthefinalphaseoftheconstructionworks,wheretheclient transitions thebuilt formintooperationsandwherethemaintenanceperiodofthe constructed commences.Completionof theproject occurswhen all defectiveworksarerectified,omissionscompleted,andtheliabilityperiodexpires.
Theknowledgeareas,notedasQ-STC-CHRIPS,set theframeworkfor themanagementprocesses.Fromthese,theprojectconstraintsaretheQ-STCandHR(quality,scope,time,cost, resources, and risks) and any other factor that may limit options, such as client-specificrequirements.Setdates,wheremilestonesmustbeachieved,andperceivedrisksare two examples of project constraints that require effective management. As furtherconstraints are evaluated, it is important to also consider their possible influence andimpact on the remaining knowledge areas. For instance, it is unlikely that the schedule(time) can shorten without increasing risks and causing negative impacts on cost andquality.
For the purposes of construction supervision, this book focuses on the Q-STC-CHR(quality, scope, time, cost, communication, resources and risk) aspects. The remainingaspects, which include integration, procurement, and stakeholder management, are notcovered as these are regarded as not relevant to the supervision process. However,additional to these and essential to the construction management and supervisionprocesses are the HSE (Health, Safety, and Environment) aspects and informationmanagement,whichareconsideredintegralpartsoftheknowledgeareaswithinthisbook.
ConstructionProjects
Construction projects are generally contracted out to suitably experienced companieswhich have the capacity and capability to undertake the required works. The requiredworksaregenerallyoutlined inseriesofdocumentations thatconstitute theconstructioncontract,alsoreferredtoascontractdocumentsorABCD(anabbreviationofAgreement,BillofQuantities,ConstructionSpecification,andDrawings).Thesesetoutthescopeofworksand requirements, specifying suchaspectsas thenature, terms,andconditionsofthearrangement.
Once these are agreed and contract is executed, then the construction contract becomeslegallyenforceable,whereeachpartyhascontractualobligations to fulfil. It is thereforeessentialthateachpartyinvestsufficienttimetoreviewthetermsandconditionspriortocontract execution and ensure that they are clear as to what the contract, scope, and
-
corresponding conditions entail. Fully understanding these can reduce the likelihood oflater disputes or disagreements and thereby also ensure parties to the contract becomecommittedtoachievingtherequiredoutcome.
Aside from the contractual obligations, rights, and responsibilities, the true aim of anyconstruction contract is to complete the scoped works within scheduled time frame,allocatedbudget,andspecifiedquality.Possiblythemostimportantandcrucialoftheseisachievingthespecifiedqualityasthiswillavoiddelaysandtheaddedcostsofreworkandwastedmaterials.
Oncethecontractisexecuted,itbecomesessentialfortheclienttoensurethecontractiseffectively administered and performance monitored as only this will ensure contractconditions and contractual obligations are fully fulfilled. Similarly, it is important tomaintain ongoing dialogue and cooperation between parties involved in executing thecontract as each party has a responsibility to facilitate progress and, where required,impartknowledgeandprovideguidanceashowbesttoproceedandcompletetheworkswithinthecontract-specificrequirements.
Constructionprojectsareunique,unlikeanyotherproject.Theiruniquenessisduetothespecificnatureofconstructionworksandthefollowingattributes:
Constructionworkcannotbepurchasedofftheshelforimportedfromelsewhere. Constructionworkgenerallyoccursinopenareas. Constructioncontractshaveveryspecifictermssuchasacontractperiod,usually
measured in years, and thereby alsomany associated time risks that can includetechnological,financialandpoliticalrisks
Constructioncontractscanbehighlycomplexduetothefollowing:
- the large number of different disciplines involved, which can includearchitecture,civil,MEP,andbuildingspecialists
- thelargenumberofpeoplebroughttogether,manyofwhichhaveneverworkedtogetherbefore
- the high degree of specialised works, requiring specialist disciplines to bothconstructandsupervisetheworks
- theuseofuneducatedlabour- theuseofdifferentnationalitiesofworkersanddifferentworkstandards(which

- Thecontractorisfocusedonmaximisingprofitsandnotgenerallycaringaboutquality.
- Theconsultantsinterestmayvaryanddependonarrangementswiththeclient;iffeesarebasedonpercentagecosts,thentheymaybeincentivisedtomaximisetheirincomebyincreasingprojectcosts.
Each of these differences adds complexity and risks to theworks.Each also influenceshow the works can be and are undertaken. Therefore, it is essential that the inherentcomplexitiesbe taken intoaccountprior toundertaking theconstructionworks.Tofullyappreciate these requires sufficient and broad understanding as to how constructionprojects can and should be managed, underpinned by an understanding of the manyrequiredaspectsoftheworksandhowtheseshouldbroughttogether.
ConstructionSupervision
Why do we need Construction Supervision, and why do we need to establish qualitycontrol?
ConstructionsupervisionisboththeclientandCCsresponsibility.However,asinvariablytheCCspredominantfocusisonachievingcompletionoftheworksquicklyatthelowestpossiblecost,theclientmustplacesomeemphasisonensuringtheworksareconstructedasdesigned,documented,andarecompletedincompliancewiththecontractdocuments.Toachievethis,theclienthastwooptions,whichareeitherofthefollowing:

complexity to the contractual arrangements, requiring the appointment of suitablyqualifiedpersonnel(PM,CAdmin,CS);however,whenconsideredfully, theseadditionsare inconsequential to thepotential riskof failure andoverallproject cost.Constructionoversightprovides theassurance thatworksundertakenwillmeet the specifiedstandardandtheeventualoutcomewillbeasdesignedanddocumentedand, thereby,achievethedesigned operational life.And should any future building issues arise, then the recordsproducedbytheoversightteamcanbeusedtoinforminvestigationsastowhetherfailureswere due to design or due to construction error, which is important in apportioningliability.
Constructionsupervision isaprocessused tomonitorandreviewtheworksundertaken,capture relevant data of what has occurred, confirming (and ensuring) compliance andproviding an insight as to how theCC is performing. To be effective, the constructionsupervision processmust be proactive and follow the dictum Prevention is better thancureasthiswillensureasuccessfulcompletion.
TheCSsRole

TheappointmentoftheCSshouldbebasedonabilitytoeffectivelyfulfilroleobligationsand specific requirements for theworks. It is also preferable that theCS also has priorexperience in the same type of works as being undertaken. For QSE matters, it is,however, essential to have relevant past experience (and training) as this will ensurecomplianceisachievedandwillfacilitatetheworksprogress.

time.- Conditions that may lead to unsatisfactory work should be anticipated
whenever possible and when identified should be communicated(preferablyinwriting)totheCCatearliestopportunitytoavoidwasteofmaterials,labour,andstrainrelations.
- During the works, the CS should not delay the CC unnecessarily norinterfere with the CCs methods unless it is evident that unacceptableworkwillresult.
- Cooperation with CC, such as conducting inspections promptly and
-
thoroughly,isessentialtofacilitatetheworksprocess.
MonitorQSEaspectsandrecordactivities,includethefollowing:- Be present on-site regularly during the CCs daily working hours (in
accordancewithITPs/HWPsandtoensureSWMScompliance).- Visit the testing laboratory to verify that appropriate test standards are
being applied and ensure all test results are reported and recordedcorrectly.

This example highlights that there are inherent risks associated with each part of theconstruction works.

A suitably experienced CS with sufficient knowledge of the required works should beconfident to take a firm stand on something known to be deficient or non-compliant.Firmnesswithimmediateactionismostoftenrequiredtopreventnon-compliancesfromoccurring.

Key to quality management is the contractual conditions and systems to be applied asthese set the QC (quality control) measures and verification processes that are to beemployed.Thiswilldependonthetypeofcontractadoptedconstruct-only,design-and-construct, or performance type of contractas each has a different focuswith varyingconditions relating to quality.

The company QA (quality assurance) processes, such as monitoring andcontrolling processes,will provide themeans to achieve consistency, ensuring the rightthingsaredone,improvingthecertaintyofachievingtherequiredstandardofworks.
Key to achieving the QA requirements is the appointment of the CS (constructionsupervisor), whomust be taskedwith ensuring CC achieves the specified standard.

No two construction projects are ever the same. Therefore, substantial upfront effort isrequired to thoroughly understand thework and specific nature of the scope, completewithallitsconstraintsandrequirements.Todoso,thetotalscope,100percentofworksshould be decomposed into component parts, or work packages, limited to 80 hoursduration anddetailedwithin the schedule,with cost andquality information.This is anessentialCCrequirement,whoshouldsubmit this informationorganisedasWBS(workbreakdown structure) forCAdminandCS review, and forongoing referenceduring theworks.

Time(Schedule)Management
Since a project is a temporary endeavour, it has a schedule, a known time limit andthereby,alsoanenddate.
When time is allocated to a project, it must be managed. Project time is managed bysettingmilestoneswithinaworkschedule,whichalsoestablishes thebaselineforwhichtheworksmustbeundertaken.Theproject schedule isdevelopedas theprojectwork isdecomposedintoworkpackagesandaseachelementisallocatedtimeandsequencedwithrespecttothewholeworks.Oncecompleted,thisbaselinecanthenbemonitoredtoensurecompliance.Ofvitalimportanceisthecriticalpath4fortheworks.
The established critical path within the schedule set the time required to complete theproject.Alongthispatharethemostcriticalactivities,allrequiringspecialcaretoplan,execute, monitor, and control. Potential delays that might occur from poor quality andthereby requiring rectification or rework can be avoidedwith effectivemanagement ofthese critical activities. Effective management of these can also ensure the baselinescheduleismetandpossiblyreducetheoverallprojecttime.

CommunicationManagement

Communicationscanbeformalorinformal,writtenorverbal,andacombinationofthese.However, for construction works and when communicating between the differentcontractingparties, it isadvisablethatallcommunicationsbebothformal(i.e. issuedbyauthorisedperson) andwritten. It however is necessary toundertake extensive informalandverbalcommunicationsinorderunderstandunderlyingcausesbehindemergingissuesand concerns, so these can be resolved amicably and quickly. Results from informaldiscussions should always be confirmed in writing, preferably as minutes of meeting,listingkeydiscussionitems,decisionsandinstructionsissued.
Typically,themostcommonformsofconstructioncommunicationsincludethefollowing:
informaltelephoneoremailcommunicationsusedtoconveyaquickmessageordecision

presentationsused to inform key stakeholders of major milestone events andaccomplishments
formalwritten communications (project reports, directions, approvals, variations,andnotices)usedtoinformkeystakeholdersofprojectinformationanddecisionsinaccordancewithestablishedcommunicationprotocols.
Of greater importance than the form of communication is the relevance of informationcontainedwithinthemessage,whichislargelydependentonthedatagathered,howitisprocessed, interpreted, and assessed. See the section titled 6D (Data, Information, andDecision-Making)below.Themessagesignificant shouldalso influencehow it is tobedelivered. For instance, for priority and urgent messages, these should be relayedimmediately,wherepossible,inperson,byphone,orbytextandalwaysfollowedupwithformalnotice.Invariably, themostimportantinformationwillrelatetocontractualorQ-STC-HSEissuesathand,whichmustbecommunicatedthroughnoticesandinstructionsasfollows:

The benefit of listing the HSE requirements upfront is the establishment of a plannedapproach to manage the HSE aspects and ensure compliance. Adopting a plannedapproach has a potential to reduce potential accidents (health related) or incidents(environmental) and, thereby, maintain worker morale, reduce sick leave and staffturnover,andpossiblyenhancetheCCsreputation.

There are commonalities between QC (quality control), OHS (occupational health andsafety),andenvironmentcontrol(QC+HSEorQSE).Eachiskeytoconstructionworks,and each requires a proactive management approach to achieve compliance. Byintegrating these with one management system, certain efficiencies can be gained asduplicationofeffortisreducedwithrespecttoplanning,implementation,monitoring,andcontrolling activities. It is therefore advantageous for CC to adopt an approach that isintegratedand is able to effectively linkqualitymanagement, safety, andenvironmentalprotection.

6D(Data,Information,andDecision-Making)
Knowledgeisgainedfrommanysources,frombooks,fromteachingandgainedfromtheexperience of doing. And with new insight, the existing current knowledge can betransformedintonew.
Relevantdataisrequiredtomakeinformeddecisions.Fordatatoberelevant,itmustbetimely,accurate,appropriatelycollated,andcorrectlyinterpretedsoitistransformedintomeaningful information and for it to become insightful knowledge. For constructionworks, theCSs role is key toobtaining relevantdata as theCS is, inpart, taskedwithrecording and reporting site activities as these occur. Once data is collected, theconversion process must be sufficiently comprehensive and robust enough so data isinterrogated and becomesmeaningful information that is readily applicable. The figurebelowliststhesixkeystepsofthe6D,ortheD-cycleprocess.
Figure2.1Thesixkeystepsof6D.
There are key differences between data, information, and knowledge. Data is typicallysourced from observations and measurements as undertaken by CS. Data is the rawmaterial of information. Once data is compiled, collated, and interpreted, it is givenmeaning, which transforms it into information. The data-gathering process is as muchabout recording and reporting site activities as these occur as it is about measuring toensurecompliance.Thisisaprocessthatrequiresobservationandtestingoftheworkstogainsufficientdataand,thereby,informationthatconfirmstherightthingsarebeingdoneasspecified.
The information generated may need to undergo many reviews for it to be correctlyinterpreted. As information is examined, interrogated, tested, analysed, applied, andconfirmed,knowledge iscreated.Knowledge is theawarenessorunderstandingof factsderivedfromtheinformationprocessedandfromtheselfthroughperception,experience,
-
and learning. And with knowledge of what is occurring, project practitioners have thepotential to make effective decisions that either maintain or improve constructionperformance.
Information is not knowledge.Theworld is drowning in informationbut is slow in theacquisitionofknowledge.Thereisnosubstituteforknowledge(W.EdwardsDeming).
Itisknowledgethatenableseffectivedecision-making.Knowledgeprovidesthenecessaryappliedenlightenmentthatallowsappropriatechoicestobemade,whichmustbemadeinatimelyfashion.Knowledge,however,istimesensitive,whereinanydelayintheuseofacquired knowledge or information reduces both its relevance and value. Through timeand inaction, the acquired knowledge can easily become irrelevant and revert to a fact,data.
Effectivedecision-makingcanbeachievedthroughasix-stepprocessknownas6D,orDcycle. This six-step process consists of data gathering (1D), data processing (2D),described information (3D), described-information processing (4D), defined knowledge(5D),anddecision-making(6D).Seediagrambelow.
Figure2.2The6D,orD-cycleprocess.
The decision-making process is, however, as important as how it is communicated.Alldecisions should therefore be communicated in a clear and understandable manner asinstructionsornotices issuedbyauthorisedpersons.Equally,all instructionsandnotices
-
should employ specific protocols, such as naming and numbering conventions so eachelement, activity, area, structure, zone, and project can be readily identified within themessageandtracked.
PerformanceMonitoringandManagement
TheprojectperformancerequirementsintermsofQSE-STC(quality+HSE,scope,time,cost)forconstructionworksaregenerallyestablishedbytheclientandarticulatedinthecontract documents. To confirm, the CC should provide a work baseline schedule thatdetailshowtherequiredperformanceforeachitemwillbeachieved.Thisbaselineshouldincludethefollowing:

CHAPTER3
Phase1:Pre-ConstructionInitiatingandPlanningtheSupervisionWorks
Prior to commencement of construction, it is important to determine and establish therequired management processes. One key aspect to consider is the monitoring andverification of construction worksconstruction supervision. This is the onlymanagementprocessthatcanverifyand, thereby,ensuretheright thingsaredonetothespecifiedstandard.
Thechoicetomonitorandverifyconstructionworkswillinevitablyinfluenceeveryotherdecisionfrom type of contract used, contractor selection, how site risks are to bemanaged andmitigated, howworks are to be inspected and supervised, and how non-compliances are tobe rectified.Equally, the typeof contract adoptedwill influence theconstruction supervision process by the set contract conditions. It is therefore useful toreviewthecontract,itsrequirements,anddeterminewhethertheseareappropriatefortheworkspriortoproceedingtoconstruction.
Oncethedecisionismadetosupervisetheworksandappropriatetermsareincludedintheconstruction contract, it is important to finalise the requirements. These requirementsinclude:
