DETAILED ANALYSIS OFTHE MODIFICATIONS BROUGHT
ABOUT BYTHE REVISION OFTHE CENTRAL
PRODUCT CLASSIFICATION
Note bytheSecretariat
Addendum
PROFESSIONAL SERVICES
1. Paragraph 5ofthereport ofthemeeting oftheCommittee onSpecific Commitments heldon
10October 1996, states that"...theSecretariat should takeupcontact withtheVoorburg Group with
aviewtoinforming theCommittee inthenearfuture ofanyproposed changes totheCPCwhich could
beofinterest intheCommittee 'sdeliberations ".
2. Thestatistical committee oftheUnited Nations adopted atits10-14 February 1997 Session
thedraftCPCRev.1 proposed bytheVoorburg group. Adefinitive version ofRev.1 hasnowbeen
finalizedandwillsoonbedistributedtoMembers.ThisdocumentwillallowMemberstoconsultdirectly
theconcordances tables andthedefinitions mentioned inthepresent noteandtocompare them with
theCPC provisional structure anddefinitions iftheyfeelituseful todoso.Thisiswhy, contrary
tothepreceding sectoral studies ontourism, energy, transport, distribution andconstruction, the
concordance tables andthedefinitions havenotbeenannexed tothepresent note.
3. Thepurpose ofthepresent noteistoanalyse indetail themodifications brought bytheCPC
rev.1 intheprofessional services sub-sector, which ispartofthebusiness services sector asdefined
intheGNS Classification (1A).1Itwillproceed through acomparison ofthecomplete structures of
bothclassifications asputinconcordance bytheCPC drafters andaswellthrough acomparison of
theirdescriptive parts. Itwillfollow theorder oftheconcordance tablebetween theprovisional CPC
andtheCPCversion 1.Theprovisional CPCwillbereferred toas"prov",CPCrev.1 as"rev",CPC
provisional items as"pXXXX", andCPC rev.1 items as"rXXXX".
4. Inthepresent note,ithasbeenthought moreappropriate toretain thetechnical terms putforward
intheprovisional CPC'spreface, andusedbytheVoorburg Group when communicating withthe
Secretariat, instead ofthose --referring tothenumbering ofthedigits --previously usedintheseries
ofnotes already issued bytheSecretariat astothetourism, distribution, construction, energy and
transport sectors. Thecoding system oftheCPCisdescribed asfollows inparagraph 33ofprovCPC
preface: "Thecoding system ofCPCishierarchical andpurely decimal. Theclassification consists
ofsections (identified bythefirstdigit), divisions (identified bythefirstandsecond digit), groups
(identified bythefirstthreedigits), classes (identified bythefirstfourdigits) andsubclasses (identified
byallfivedigits, taketogether). Thecodes forthesection range from0through 9andeachsection

Paragraph 35ofprovCPCpreface adds: "Where agiven levelofclassification isnotfurther subdivided,
a"0"isusedintheposition forthenextmore detailed level."Thefollowing chart summarizes the
correspondence between these twolanguages.

7. Thispaper onlyreviews themodifications which concern theitems ofdivision p86"Legal,
accounting, auditing andbook-keeping services; taxation services; market research andpublic opinion
polling services; management andconsulting services; architectural, engineering andother technical
services" .2Thisdivision hasbeensplitintothree newdivisions: r82"professional, scientific and
technical services", r83*"other professional, scientific andtechnical services" ,andr86*"Production
services, onafeeorcontract basis" .Actually, twomain fields canbedistinguished: alarge series
ofitems areconverted indivision r82'sitems, theremainder being converted inr83'sandr86'sitems.
I. REV DIVISION 82
8. Division r82includes fourgroups: r821"legal services" ,r822"accounting, financial auditing
andbook-keeping services" ,r823"advisory services related totaxation" andr824"insolvency and
receivership services" ,thefirstthreecorresponding respectively togroup p861"legal services" ,group
p862 "accounting, auditing andbook-keeping services" andgroup p863 "taxation services" .
A. Legal Services (GNS Classification list,1Fa,CPC 861)
9. Group r821"legal services" ismainly thesame asgroup p861 which issimilarly entitled.
However itincludes nowarbitration andconciliation services, assubclass p86602* "Arbitration and
2Modifications which concern theitems ofdivision p93"Health andsocial services" arestudied inaseparate
paper: seedocument S/CSC/W/6/Add.13.S/CSC/W/6/Add.10
Page4
conciliation services" ,previously partofmanagement consulting services hasbeentransferred tolegal
services andmore specifically toclassr8219 "other legaladvisory andinformation services" .Apart
from that,atthesubclass level, themain differences arethefollowing:
a) Theexplanatory noteattached tosubclass r82111 "Legal advisory andrepresentation services
concerning criminal law"(corresponding top86111) hasbeenconsiderably simplified, notably
byrefraining frommentioning thatacting asaprosecutor inacaseofcriminal offence when
private legalpractitioners arehired onafeebasisbythegovernment,3andthatpleading acase
incourt aswellasout-of-court legalwork, areincluded inthesubclass.
b) Theexplanatory notetosubclass r82130 "Legal documentation andcertification services"
(corresponding top86130) hasbeen substantially redrafted, andisnowitemized. This
explanatory noteexpressly distinguishes, ontheonehand, patents, copyrights andother
intellectual property rights asmuch astheyareconcerned withthe"preparation, drafting and
certification ofaspecific typeoflegaldocuments" ,and,ontheother hand, the"provision
ofrelated legalservices including theprovision ofadvice andtheexecution ofvarious tasks
necessaryforthedrawinguporcertificationofpatents,copyrightsandotherintellectualproperty
rights", thisdistinction being anovelty compared totheformer definition contained intheinitial
subclass. Thisappear tobebased onprofessional specialization attached tointellectual property
practice, inparticular toservices provided byintellectual property agents related tothe
acquisition andmaintenance ofintellectual property rights. However itshould benoted that
registration andother similar services arenotnormally required inallareas ofintellectual
property rights including intheareas ofcopyright andrelated rights. Inaddition patent,
trademark, copyright andother intellectual property rights consultancy services areitemized
separately from services related tolegal documents necessary forregistration inthe
explanatory note;
c) Subclassp86190"Otherlegaladvisoryandinformationservices"concordswithsubclassr82199
"Otherlegalservicesn.e.c."andsubclassr82400"Insolvencyandreceivershipservices".Group
r824"Insolvency andreceivership services" isthelastgroup ofdivision r82"Professional,
scientific andtechnical services" .Thisgroup comprises onlyoneclassandonesubclass, r8240
andr82400, bothhaving thesame titleasthewhole group itself andhaving noattached
explanatory note. According totheconcordance tables, thecoverage ofsingle-subclass r82400
(andtherefore group r824asawhole) wasinitially partofsubclass p86190* "Other legal
advisory andinformation services" ,while notmentioned atall.Thefollowing explanatory
notedefines thecoverage ofthissubclass: "This services consists ofproviding advice and
assistance tothemanagement and/or creditors ofinsolvent businesses and/or toactasreceiver
ortrustee inbankruptcy".
10. Anewfeature should bementioned: introduction ofarbitration services inthefieldoflegal
services. Subclass r82191 precisely refers to"assistance services involving arbitration ormediation
forthesettlement ofadispute between labour andmanagement, between businesses orbetween
individuals" ,which nearly verbatim corresponds tosubclass p86602 "Arbitration andconciliation
services" ,transferred from group p866 "services related tomanagement consulting" ;concordance
tables haveconnected these subclasses. While theoriginal explanatory noteofthesubclass p86602
usedtoexplicitly exclude representation services onbehalf ofoneoftheparties inthedispute and
consulting services inthefieldoflabour relations, theintroduction ofarbitration andconciliation in
3i.e.when there isnoexercise ofstateprivilege concerning justice, asnecessarily provided bycivilservants
inthecontext ofpublic service; seesubclass r91270 "Law courts related administrative services".S/CSC/W/6/Add.10
Page5
therealm oflegalservices hasnecessitated thatthescope oftheexclusion beextended to"representation
services onbehalf ofoneoftheparties inthedispute, cf.82120", withdeletion ofanyexplicit mention
labour relations.
11. Insubclassp86602"Arbitrationandconciliationservices",representationandconsultingservices
rendered byrespectively business andemployers organizations andtrade unions arealsoexplicitly
excluded, butthisexclusion hasbeenomitted innewsubclass r82191.
B. Accounting, Auditing andBookkeeping Services (GNS Classification list,1Fb,CPC 862)
12. Group r822"accounting, financial auditing andbook-keeping services" hasexactly thesame
structure andthesame content asprovisional CPCcorresponding group, p862 "Accounting, auditing
andbook-keeping services" ,except forsome minor changes ofdefinition andwording. Forinstance,
theword "financial" issystematically introduced asacharacteristic of"auditing".4
13. Insubclass r82213 "Compilation offinancial statements services" ,theword "bundle" replaces
theword "package", withnoapparent change ofsignification asthese words areusedassynonyms.
Insubclass r82220 "Book-keeping services, except taxreturn" ,theexclusion of"payroll services,
includingpayrollcomputationandledgers",whicharerelatedtor85990"Othersupportservicesn.e.c.",
isadded toinitial exclusion of"book-keeping services related totaxreturns" .
C. Taxation Services (GNS Classification list,1Fc,CPC 863)
14. Group r823"Advisory services related totaxation" corresponds top863"Taxation services" ,
whose titlewasambiguous asitseemed toapply totaxation initself, which isastateprerogative.
Inanunusual manner, revdescribes thescope ofthewhole group, using theintroductory sentence
"thisgroup includes: ...",whereas inthewhole CPCsuchasentence usedtobesystematically repeated
onlyatthetopofeachsubclass.5Thus thedescription given canbeseenasageneral summary of
subclasses definitions, butitmoreover includes thecomplete wording oftheoldsubclass p86309 "Other
taxrelated services" :"services consisting inassisting enterprises intaxplanning andcontrol other
thanincome taxandpreparing alldocumentation required bylaw",which hasnoequivalent subclass
inrevasatthesametimeitscontent hasbeenequally distributed todifferent subclasses defined through
types ofservice ortypes ofclient. Thetworeverse concordance tables linking revtoprovandprov
torevdonotmention therelationship between thisunusual explanatory noteplaced atthegroup level
andprovinitial subclasses explanatory notes.
15. Atthefour-digit level, classp8630 "taxation services" ,which wasthesoleclassofgroup p863,
hasbeenreplaced bythreenewclasses: r8321 "corporate taxplanning andconsulting services" ,r8322
"corporate taxpreparation andreview services" ,andr8223 "individual taxpreparation andplanning
services" ,thegeneral scope ofwhich issimilar tothescope ofcorresponding prov single-class.
4"Auditing" generally --butnotexclusively --refers tofinancial matters. Incertain countries auditing practice
includes areview oftheadministration ofthefirmbyauditors. Furthermore, intheCPC theconcept of"audit"
hasbeen usedinother contexts thanfinancial services, such asforinstance when mentioning theperforming
ofanaudit onthecomputer-related operations oftheorganisation insubclass r83141 "Hardware consultancy
services" .
5Inprovisional CPC, explanatory notes exist incertain cases atthedivision level (two-digits) andatthe
sectionlevel(three-digits),suchasforinstanceinthecaseofdivisions51"Constructionwork",52"Constructions",
53"Land", andforsection 6"Trade services; Hotel andrestaurant services".S/CSC/W/6/Add.10
Page6
However, atthefive-digit level, therespective scopes ofevery subclass areredistributed, aseachprov
subclass includes partofoldp86309* "Other taxrelated services" ,asmentioned intheprevious
paragraph. Inorder toreflect services dedicated to"individuals", theword "business" usedinprov
hasbeenreplaced by"corporate" inrev,inthatwayintroducing adivision bytypes ofclients.
16. With regard tothefeature ofexplanatory notes, itappears thatrevhaspartially turned toa
more laconic redaction; thus,r82310 "Corporate taxplanning andconsulting services" hasnoattached
explanatory note, contrary toitscounterpart inprovp86301 "Business taxplanning andconsulting
services" ,whose explanatory noteexplained withacertain sense ofdetail thatthese particular services
aimatadvising "enterprises onhowtoarrange theiraffairs, withaviewtominimizing theimpact of
income taxation ontheirprofit bytaking advantage ofallallowances andbenefits thatthelawprovides" ,
withemphasis putonexclusion oftaxpreparation andreview services relevant top86302 "Business
taxpreparationandreviewservices".Similarly,r83320"Corporatetaxpreparationandreviewservices"
onlymentions "preparation ofreturns forallkinds oftaxes (e.g.VAT)" ;yet,r82330 "Individual
taxpreparation andplanning services" isamutatis mutandis itemization ofevery component ofthe
single definition contained inprovsubclass p86303 ".
II. REV DIVISIONS 83and86
17. Division r83*"Other professional, scientific andtechnical services" isthesecond important
division resulting fromthesplitofDivision p86. Thegeneral framework ofr83isinsubstance very
similar totheframework ofthecorresponding partofp86(i.e.thepartnotyetcorresponding todivision
r82"professional, scientific andtechnical services" ).However, division r83includes parts ofprov
divisions p51*"construction services", p75*"post andtelecommunication services", p84*"computer
andrelated services" andp87* "business services n.e.c." .
18. Furthermore, certain items offormer division p86arefound indivision r86*"Production
services, onafeeorcontract basis" .Thisonlyconcerns elements which haveresulted froma"split"
ofonedivision p86'sitem, whose other elements havebecome division r83'sitems, Thetransfer under
divisionr86*"Productionservices,onafeeorcontractbasis"ofmaterialoriginallycontainedindivision
p86remains therefore marginal.
19. Atthethree-digit level, thecontent offouroriginal groups (p864, p865, p866, p867) have
beentransferred under sixnewgroups (r837, r831*, r832*, r833*, r835, r865*).
- Onlygroup p864 "Market research andpublic opinion polling services" corresponds
toasingle revgroup: group r837, which hasthesame title.
- Group p865 "Management consulting services" hasbeenmerged withparts ofp866
"Servicesrelatedtomanagementconsulting"andgroupp867"Architectural,engineering
andother technical services" inorder toform thenewgroup r831"Consulting and
management services" .
- Group 866hasbeensplitanditssubstance hasbeenredistributed totwonewgroups
which alsocomprise other material: r821"Legal services" (already examined) and
r831"Consulting andmanagement services" (already mentioned).
- Group p867 hasbeensplitintofivecomponents, anditssubstance, onceaggregated
toother material, hasbeenusedtocreate fournewgroups: group r831"Consulting
andmanagement services" (already mentioned), group r832"Architectural services
andurban planning andlandscape architectural services" ,group r833"EngineeringS/CSC/W/6/Add.10

services" ,group r835 "Scientific andother technical services" ,andgroup r865*
"installation services (other thanforconstruction)" .
- Besides,groupsdetachedfromotherprovdivisionshavebeenenteredinthisrevdivision
framework:namely,p871"Advertisingservices"becomingr836"Advertisingservices",
p875"Photographic services" becoming r838"Photographic services andphotography
processing services" ,p879* "Other business services" splitting andbecoming partly
r839"Other professional, scientific andtechnical services" andpartly r834"Specialty
design services" .
20. TheGNSClassification onlyrefers toclasses 8671"Architectural services", 8672"Engineering
services", 8673"Integrated engineering services" and8674"Urban planning andlandscape architectural
services", allofthem parts ofgroup 867"Architectural, engineering andother technical services".
These classes arecitedwiththesame titleintheGNS Classification aspoints e.,d.,f.andg.
21. Asgroup p867 hasbeenbroken upintofivecomponents, eachaggregated toother material
inorder tocreate fournewgroups: group r831"Consulting andmanagement services" ,group r832
"Architectural services andurban planning andlandscape architectural services" ,group r833
"Engineeringservices",groupr835"Scientificandothertechnicalservices",andgroupr865"Installation
services (other thanconstruction)" ,thishasproduced arather complex framework ofclasses and
subclasses related toeachofthese newgroups.6Since group r835doesnotcorrespond toanyitem
ofprovisional CPCincluded intheProfessional Services sub-sector oftheGNSClassification (Section
1,para. A),theircarrying overtoCPC rev.1 willnotbeaddressed intheremarks below.
22. With regards togroup r831* "Consulting andmanagement services" ,theonlyconnections
made byconcordance tables concern subclass p86729 "Other engineering services" ,which hasbeen
related tosubclass r83131 "Environmental consulting services" andsubclass r83139* "Other scientific
andtechnical consulting services n.e.c." .
23. Infact,subclass p86729 concords withaseries ofnewsubclasses: inaddition totheabove-
mentioned, areconcerned allthesubclasses under class r8339 "Other engineering services", which
concern fourtypes ofbuildings: 1)"Buildings"; 2)"Civil engineering works"; 3)"Industrial plant
andprocess"; and4)"Other projects" (seeinfraparagraph 28).Themainelements ofsubclass p86729
havebeentransferred under thisseries ofsubclasses.
24. Asfarasgroup r832"Architectural services andurban planning andlandscape architectural
services" isconcerned, group p867 classes involved inthenewframework arep8671 "Architectural
services" ,linked toclassr8321 "Architectural services" together withclassp5111* "Siteinvestigation
work" ,andclassp8674 "Urban planning andlandscape architectural services" ,related toclassr8322
"Urban planning andlandscape services" (corresponding tothe"architectural" component ofgroup
p867).
25. Theframework ofsubclasses under newclassr8321 havebeensubstantially recast. Former
subclass p86711 "advisory andpre-design architectural services" hasbeenconnected tosubclass r83211
"Architectural andpre-design services" andsubclass p51110* "Site investigation work" ;former
subclasses p86712 "Architectural design services" ,p86713 "Contract administration" andp86714
6Fortheclarity ofthefollowing presentation ofthemodifications appearing intheitems inrevcorresponding
togroup p867 sub-items, revitems willbereferred inthefirstinstance, notwithstanding thegeneral principle
followed inthepresent notewhich consists tostartfrom provitemandthen, from thisbenchmark, todescribe
modifications arising from thecorresponding items inrev.S/CSC/W/6/Add.10
Page8
"Combined architectural design andcontract administration services" havebeengrouped andlinked
tosubclass r83212 "Architectural design andcontract administration services" ;andformer subclass
p86719 "Other architectural services" corresponds tonewsubclass r83219, which hasthesame title.
26. Thetwosubclassesformerlyattachedtoclassp8674"Urbanplanningandarchitecturalservices",
p86741 "Urban planning services" andp86742 "Landscape architectural services" ,correspond tonew
subclasses r83221 "Urban planning services" andr83222 "Landscape architectural services" ,having
thesame titles.
27. Theexplanatory notesattached toeachsubclass havenotbeenmodified except mutatis mutandis
itemization, andexcept thedisappearing ofthewhole content ofexplanatory notes under subclasses
p86713 "Contract administration services" andp86714 "Combined architectural design andcontract
administrationservices",unifiedundersubclassr83212"Architecturaldesignandadministrationservices"
withsubclass p86712 "Architectural design services" ,explanatory noteunder thelatter hence being
theonlyonepreserved.
28. Asfarasgroup r833"engineering services" isconcerned, group 867classes involved inthe
newframework arethefollowing: p8673* "Integrated engineering services" corresponding tor8331,
having asimilar title,andclassr8332 "Project management services concerning construction"7;and
p8672* "Engineering services" ,which splits intofournewitems, namely classr8333 "Advisory and
pre-design services" ,class r8334 "Engineering andpre-design services" ,class r8335 "Engineering
services during theconstruction andinstallation phase" andclassr8339 "Other engineering services" .
29. Onengineering matters, revhascreated anewframework ofsubclasses based ondistinction
oftypes ofbuilding projects andtypes ofservices supplied atdifferent levelofbuilding process. In
thisrespect, fourtypes ofbuilding project areseparated: 1)"Buildings"; 2)"Civil engineering works";
3)"Industrial plant andprocess"; and4)"Other projects". Sixtypes ofservices aredistinguished:
1)Integrated engineering services (r8331), 2)Project management services concerning construction
(r8332), 3)Advisory andpre-design services (r8333), 4)Engineering design services (r8334), 5)
Engineering services during theconstruction andinstallation phase (r8335), and6)Other engineering
services (r8339). Therefore, asfaraseachtypeofservices supplied appears atclass level, theset
ofsubclassesrelatedtoeachclassaccordinglydistinguishesfourtypesofbuildingprojectscorresponding
toeachbasic typeofservice supplied. Concerning thelinkbetween explanatory notes andsubclasses
framework inrevandprov, itisworth noting thefollowing differences:
(a) Classr8331"Integratedengineeringservices"(relatedtoex-classp8673"Integratedengineering
services" )comprises ageneral explanatory noteatclasslevel, therefore applying tothewhole
series ofsubclasses. Theexplanatory notes under subclasses simply stipulate which arethe
types ofbuilding involved inthesupply ofservices. Subclass r83311 ("Building") isrelated
tosubclass p86739* "Integrated engineering services forturnkey project" ;subclass r83312
("Civil engineering work") isconnected tothree different subclasses, p86731* "Integrated
engineering services fortransportation infrastructure turnkey projects" ,p86732* "Integrated
engineering andproject management services forwater supply andsanitation works turnkey
7Itshould benoted thatinaprevious version ofCPC rev.1, subclass r8332 "Project management services
concerning construction" didnothavenoequivalent categories inprov, andthattheconnection withclassp8673*
"Integrated engineering services" actually results from arecent initiative oftheVoorburg Group. Thefollowing
explanatory noteisattached toclassr8332: "Thissubclass includes: -services ofassuming overall responsibility
forthesuccessful completion ofaconstruction project performing management andcontrol functions -project
management services provided byengineers orarchitects ";excluded areinstallation services ofturnkey projects
(related tor86510) andgeneral construction services (r841 andr842). There isnoiteminrev.withnoequivalent
category inprov.S/CSC/W/6/Add.10
Page9
projects" andp86739* "Integrated engineering services fortheotherturnkey projects" ;subclass
r83313 ("Industrial plantandprocesses") corresponds toanaggregation ofp86733* "Integrated
engineering services fortheconstruction ofmanufacturing turnkey projects" andp86739*
"Integrated engineering services forother turnkey projects" ;finally, subclass r83319 ("Other
projects") islinked top86739* "Integrated engineering services forother turnkey projects"
(thislatter subclass isthecommon denominator ofthegeneral framework ofconcordance).
Noexplanatory notehassofarbeenreintroduced.
(b) Class r8332 "Project management services concerning construction" refers tothesame
differentiation bytypeofbuildings. Thesame principle ofdefining theservices inanote
introduced attheclasslevel, andthenindicating thetypes ofbuildings concerned atthesubclass
level, hasbeenapplied. Subclass r83321 ("Building") isrelated tosubclass p86739* "Integrated
engineering services forturnkey project" ;subclass r83322 ("Civil engineering work") is
connectedtop86732*"Integratedengineeringandprojectmanagementservicesforwatersupply
andsanitation works turnkey projects" ;subclass r83323 ("Industrial plant andprocesses")
corresponds tosubclass p86733* "Integrated engineering services fortheconstruction of
manufacturingturnkeyprojects";finally,subclassr83329("Otherprojects")islinkedtosubclass
p86739* "Integrated engineering services forother turnkey projects" andsubclass p86731
"Integrated engineering services fortransportation" .Noexplanatory notehassofarbeen
reintroduced.
(c) Class r8333 "Advisory andpre-design services" comprises thesame differentiation bytype
ofbuildings, butconcordance tables onlyrelate thesubclasses top86721* "Advisory and
consultative engineering services" .Theexplanatory noteissimilar. Theasterisk obviously
concerns thedivision infoursubclasses related todifferent types ofbuilding projects.
(c) Astoclass r8334 "Engineering design services" ,itshould benoted thattherecast ofthe
explanatory note(only oneforthecomplete framework offoursubclasses) corresponds toa
pre-existing matrix which isapplied tothewhole range ofsubclasses attached toformer class
p8672* .Actually, subclasses p86722 "Engineering design services fortheconstruction of
foundation andbuilding structure" andp86723 "Engineering design services formechanical
andelectrical installations forbuildings" correspond tor83341 ("Building"), subclass p86724
"Engineering design services fortheconstruction ofcivilengineering works" corresponds to
r83342 ("Civil engineering work"), subclass p86725 "Engineering design services forindustrial
processes andproduction" corresponds tosubclass r83343 ("Industrial plantandprocesses"),
andsubclass p86726 "Engineering services n.e.c." corresponds tor83344 ("Other projects").
30. Class r8651 "Installation services ofturnkey projects" hasbeenrelated classp8673 "Integrated
engineering services" .Infact,thesingle-subclass under thisclass, namely r86510 "installation services
ofturnkey project ",results fromthe"merger" ofelements taken fromthewhole series ofsubclasses
underp8673:p86731"Integratedengineeringservicesfortransportationinfrastructureturnkeyproject",
p86732 "Integrated engineering andproject management services forwater supply andsanitation works
turnkey projects" ,p86733 "Integrated engineering andproject management services forwater supply
andsanitation works turnkey projects" ,p86739 "Integrated engineering services forother turnkey
projects ".
