Intr oduction

Plan ning the construction projectis vitalto ensu re that work is ca rr ied ou t to the required quality,withinthe specified time andaccord ing to budget.Dueto thenature of co n struction work in wh ich man y uncertainties are involved,divergencesfrom the original plan are common ,When the differencesbetwee n theplan and the actual workperformanceare large,control actions arctaken tobring theactualperformance back oncour se with the original plan.

In monito ring project performance, measuremen ts are taken and compared with thedesired orexpected valuesas the

project progresses. However, the typicaI measurementsmadearelimitedin number becau se ofthecost ofdata collectionand restrictions by com pan)' policy and precedence [Al-jibo uri, 2002). Due to the nature of data available, it is difficult to determ ine the actual performance in a project. The complex ity and the limited number of measur ements willprovidealess th an com plete picture of the actual performance.

The main aim of this pape r is to ascertain the problems associated with the im plemen tati on of project plan ning

and control fr om the vie wpoints of construction consu ltants and con tractors in a develo pi ng cou nt ry. The secon d object ive is to identify th e positive and negativeim p acts in impl ementi ng project planningandcon trolfrom the persp ectives of thepartiesinvolvedinthestud y. Fina lly, the critical success fac tors are identified for succes sfu l pla nning and projec t performance.

Project Planning - An Overview Construc tion projects need tobeproperly planned,Project planningisa fundamental necessity for the construction industry playersto getsp ecificresults witha definite set ofobjectives.It isdefin ed asthe process ofidenti fying all the activ ities necessa ry to co m ple te the proj e ct suc cess fu ll y (Ober len d e r, 2000). It has also been describedbyWes tney(1985) astheprocess of brea king a project down into spe cific tasks, anddefining theseque ncein which those tasks can or mus t be performed.

According to Payne et a!(1996), project pla n ni ng means plan nin g meth od s, choosing between 'in-house' services and externalsu p p liersor constructors,deciding on cash flow for the cost pla n or budge t, and deciding on thesched u leofopera tions orthetimin g plan.

Spice (2003) highli ghted that the projectplancanbe usedto make forecasts, estimate impacts of risks and to ma ke con tingency plansfor the consequencesof delays or oth e r cha n ges in the plan. Mawdesley et a! (1997) identified the objec tives for pro ject pla n ning as a) to prov ide a basi s fo r estimating time and cost,b) to predict the timing of activi ties,

their sequence and the total con struc tion period, c) to pro vid e a basis for claims evaluatio n,in partic ularextensio nof time entitlemen tcalcu la tions,d) to predict the level of lab our, sta ff, plant and material, and e) to enable the safety, qua lity and env ironm ental im p act of the work to be prop erly considered.From themanagemen t view point, theobjectivesof properproject planning, in cl u de: a) to redu ce the 20

consequence of uncertai n ties and risks,b) to pers uadepeople toperformsequen tial taskstoens ure that the availab le resour ces arebestutilisedat all times,andc) to provide the basisforprojectcontro l(Lee,1998).

In any con struction project, the three inter -related factors of time, money and qualit y need tobe contro lled(Ma wdesley, etal.,1997).An impo rtanteffortin overa ll project con trol isthe accura cy anddetailof thefirstestim a te that becomesthe control documen t for futuredesigndecisions.The sim p les t defin ition of project con trolling, accordingto Babcock(1991), is compe lling eventstoconformto plans.Control entails seeing that project tasks are carried ou t accord ing to pla n an d to avoid lar g e deviationsfro mthe plan(Roman,1986).

Controlling a project is done by measuring performance and correc ting dev iati onfrom the projectplan(Lee,1998).

It begins with the identifi cati on of the owner's objecti ves and ends wh en th ose objectiveshavebeenmet(Gouldand]oyce , 2002). Con trolling a construc tio n project fulfilstheneed fora) spotting mist akes,b) recognizing lack ofwork progress,and c) id e n ti fy in g areas of poor quality (Mawdesleyetal(1997)).Gou ldand Joyce (2002)identified that the purposes of project controlare to guara n tee th at the project's design,budgetandsched u le aremet by the project andtoide n tify deviationearlywhen an y objecti ve begins to slip so tha t appropriate correctioncanbemad e.

Roman (1986) pointed out that the objectivesof project controlare:

a) to minimizelo ssandtheconsequences of poorperformance, and

b) to en h a nce project team an d client relatio ns and prevent in te rna l dis equilibrium and to promote co m m unication amo ng fun cti onal groups.

Project Planning and Control

Some of the reasons why plan ning and con trol isnecessary include:

a) to prep are for unforeseen factors to reduce conse quences of uncertainti es and risks(Lee, 1998 and Roman,1986) b) tope rsuade team s to perform tasksto ensure project's objectivesare met (ie.

tim ely completion, optimal use of resou rces etc)(Chan, 2002 and Gould and Joyce, 2002)

c) to provid ebasic coord ina tion(Benne tt, 2000)

d) to avoid com m u nica tion breakdown (Rom an ,1986andAh uja,1994) e) to fulfill finan cier's requiremen t(Ah uja,

1994) and

Q to providecontinuityof personnelwhen experienced personnel leaves (Ahuja, 1994).

Problems In Implementing Construction Project Planning And Co n t ro l

Probl e ms that usuall y occur during the implem entation of planning and control facedbythe projectplanni ng team includ es:

(1) Com mu nica tion failure (Malliet,2001), (2) Disinterest in pro ject pla nn ing and control due to perceiv ed poor returns from itsimplement ation(Clarke,1999 and Cox,1993),

(3) lack of infor ma tioninput and feedback for pla nn ing and con trol due to its image as a 'corpo rate reporting' tool (Clarke, 1999),

(4) cha nges in projects' scope(Clarke,1999 and Rakes,1992),

(5) cultura l and indi v id ual issues (Baba, 1996), and

(6) unavailability of resources (Ro ma n, 1986).

Research Methodology

The primary aims of thestudyinclu d e to ex p lo re the cu rre n t prac tices and to dete rmin e the difficulti es encount er ed during the impl em e nt ati o n pro jec t planning.Theobjeclivesof theinvestiga tion include:

The investigation is divided into th ree (3) types of inpu t to fulfill the research objec tives, nam el y: a literatu re revi e w, interview s andaquestionnaire su rvey.A literatur e revi e w was carri ed ou t to exam ine the concep t,problem associates and cu rren t practi ce on plan n ing and con tro l. A questio nna ire survey was Measuring Project Perfo rmance

Perfo r ma nce of a proje ct reflec ts the project'ssuccess or failure.In the con textof cons tru ction project performan ce, project perfor ma nce is the achie vement of the project at the endof the constructio n. Payne, et al,(1996)pointed out tha t oncethe project begins,project performanceis periodically determined so that an y necessary adjustments can be ma d e qu ic kl y.

Accord ing to Gould and Joyce (2002),the evalua tio n of act ua l perfo rmance to planned perfo rman ce is a cri tic al and recurring step in thecon tro lprocess.

Hendrickson andAu(1989) men tioned that the key fa cto rs for unsuccessful projec ts are ill defined scop e, poor management, poor planning, breakdown in communication betwe en engineering and construction, un realistic sco pe, sche d ules and budge ts, man y cha nges at variousstagesofprogressand lack ofgood projectcontro l.

Atotalof 500 questionnaire forms were mailed ou t to 300 co ntractors an d 200 consultant firms.Thesa mp le was chosen from the 2003-2004Construc tion Industr y Deve lop me n t Board (CIDIl) Directory of contractors and while the consu ltants were selected randomly from two main sou rce s name ly The Associatio n of Consulting Eng inee rs Malaysia Directory and advertisementsinlocal newspapers.

Out of the 500 questionnaire form s mailed , 20forms (4%)were retu rned mainly du e to the ch ange in the com p a n ies' addres ses. A to tal of 75 co m ple te d questionnaire swere receivedrepresenting a 15%response rate.The resp onse rate is low and this low response may be due to the lack understan di ng of the needed informati on ,lackofinteres t in the surveyor even the lack of aw ar ene s s on the investigatedissue.

Commo" problems

Table 1.1shows the common problems encountered during implementing planning andcontrol. Fromthe contractors' perspectiv e,lackofexpe rie ncedsta ff isthe most criticalproblem in project plan n ing an d con tro l (15 .5%) foll ow ed by 'unavailability of knowled g eable sta ff' (14.7%). Planning and contro ll ing a construction project is strong ly based on the staff's experi enc e and this will result in a high demand for experi enced sta ff particularl y experienc ed in pla nn ing, if planni ng and control is trea ted seriously by the cons tru ctio n ind us try. A relatively long period is required for staff to gain invaluab le experien ce and a member of staff needs to be exposed to a varie ty of project types to be able to plan and anticipate problems. A new staff has an oppo rtu ni ty to deal on ly with a sim ple pro ject. This phe nomenon has red uced the cha nc e fo r the yo u nger and newer stafftobeexpo sed to the variety ofworks and problemsand the available su p ply of experien ced staff ca nnot meet the high deman d of the cons truc tion industry and cons eque ntly has resulted in the lack of expe riencedstaffin theind ustry.

In con tras t, thecon sultants identified thetwo main probl em sencountereddur ing project planning and con tro l as 'poo r coordination'(15 .9%)and'com munication problem' (14.3%) asillust ra ted inthe Table 1.2.

Problelllsduringplnnningnlldcontrolling cons truction projecttime

It was obse rve d that the three most signifi cant pro bl ems in pla n n ing an d con tro lling project time as perceiv ed by the con trac tors an d cons u lta n ts as shown in Table 1.3 belo w are 'de lay in decisi on-m ak in g ' (16.7%), 'change in design and construction method' (15.7%) and 'unforeseen sitecond ition'(15.6%).

Delayin decision-makingmay bedue to poorunderstanding or lack of knowled ge about a pa rtic ula r problem . The process of investigating and und er st an ding the proble m will spend some considera ble tim e. In add itio n, lack of a systematic docum entation system in recording the project informat ion can cause failures in passin gpertin ent info rma tion upanddown in a projectconuuunicationstructure. This may causedifficulty for a decision makerin gathe rin g essential inform ati on and thus causes delayin decision making.

Clientshave the tend encyto reducethe cost for a construc tio n project during the start,for example, by cha ng ing theinitial desi gn s and constru cti o n method s / material. After the commen cement of the cons truction work, new need s or even a change of mind from the clie n t or his rep resentative will give rise to variation orde rs that will fo rce the contractor to accept the new designs orcons truct io n method s.Hence,more timeisrequired to accommodate these cha nges in desig ns and cons truction methods .

Unfore s e en site con d i tions that unexpectedly ariseou tof,say, probl ematic ground con dit ion orobs tructions that arc not id entified befor e a projec tstar ts will ultimat ely slow down the pro gr ess of a project.

Pmblellls ill pl anniug ant! controlling constructionproject cost

Tabl e 1.4 pres ents the problems encountered in planni ng and con trolling project cost. "Unex pec ted mar ket fluctua tion" was ide nti fied as the most crucial (20.0%). Changes in the global econOlny have, attimes,caused theprices of raw materialsto fluctuateunexpectedl y.

Increases in the price of cons truc tion material s such as cem ent and stee l will directly increasethe project cost. Inad d ition, sho rtage of materials would also be the result of excessive demand oversupplyin the market. This may causethe price of raw materials to fluc tuate unp redictabl y. These sit ua tions ha ve mad e the cons truc tio n marketdifficultto pred ictandcon tribu ted to difficulties in estimat ingtheprojectcost.

'Inaccurate inestima te'wasidentifi ed asthe second criticalprobleminplanni ng and controlling construction project cost (18.4%).Early costestimateis done based on the project initialdesign bu tcha ngesin design,whichoften affect the projectcost, alway s occur afte r the cons truc tion has comme nced. The lack ofexper iencedstaff in esti ma ting wi ll con tr ib u te to the unr eliable project estima te as the re is no standardor specificformula for estimating the project cost. Allthe estimationsare based on the staff's experience and jud gment.

Table 1.6 shows the negative impacts of projectplanni ngand control. Responden ts claimed that 'time cons um ing' (30.2%)as themostnega tive effect.This isfollowed in descending order by 'a d d i tio n a l sta ff requ ired' (30.0% ) and 'in cre ase d co st' (22.2%).

Conclusi ons

Duetotheuncertaintiesin thecons truction ind u st ry, a projec t is highl y unlikel y to proceed in its en tire ty acco rd ing to the orig inalplan.Thisphenome no n is further agg ra va ted if pro blem s identified by the consultants,namelypo orcoordinationand communicatio n exist in a project.For the contractors, appa ren tly, the pro b le ms to implemen ta prop er project plan n ing are associated withalack ofexperienced staff an d the costinvoived. Theindustr y canbe plag u e d with a med iocre attitu de and performa nce towards planning con trolif insufficientmeasuresprevailand nothing isdone to ensurethatpooror nonexistence of "real"planni ngandcon trolbytheparti es.

The problem s as a resultof poorplanning and control documentation will continue to exist for the clien ts, cons ulta nts and con tracto rs if plan ni ng an d con trol docum entationsarenotupdated, recorded andarch ived.This aspectofplanning and contro l can lead to delays in processing of claims , the project progres s and may affec t the progress of a pro ject and the rela tionships betw e en project team s.

Clien ts and cons ultants must be read y to acceptthe responsibility and consequences of any poor decisio ns an d be ar the conseq u ences of their decisi ons if the planning andcontro lrecordsshowed that they contrib uted towardsprojectdelay and increa sed cost.Withoutth e resp onsibility an d accoun tab ility attitude projec t planning will alw a ys be a cos metic requirement and serve s no real purpose for the project.The end result ma yaffect the profess ion ali s m of constr uction project management.

To overcome the im pl ernentation prob ie m that is related to cost, it is recommended that clien tsshouldap por tion a fixed amo unt of the project budget for planningand mo nitoringpurposes.Clients must be comm itted to disburse funds for planning ifplanning is to ha ve value in the local cons truction ind ustry.

value. Probably, this can overcome the issue of lack of staff that is availab le for project planning.

The studyshowedthat past experience of sta ff,altitudes towards planning and control, top man a g ement su p p o rt, appropriatechoiceofplann ingandcontro l technique s are essential ing r ed ien ts towards project plann ing and co ntro l.

Once there is a plan ning and contro l system, other factors suc h as teamw ork, expe rience of project team,good financial stand ing and realistic and definite goals would further determine thesuccessofa project.

Divergences from the plan represent a breach of the agreement and if not countered effectiv ely and in a tim el y manner the devia tionswouldalwaysresult in expanded project duration,morecosts and a lower quality. Probl ems with planning of time are associa ted with the len gth of time todecid e a particular issue and changes of design and construction method.Theproblemsincost planning are rel at ed to fluc tua ting of prices and inaccurateestimates.While the formeris quitedifficulttopredict,thelat ter hasto be tak en serio us ly if localcom panies are to competeglobally.
