2. Li e a u e Re iew
2.1. Cons uc ion Tende s and Cos O e uns
Cos o e uns in cons uc ion p ojec s ha e been he subjec o many s udies, bo h
heo e ical and empi ical, wi h li le appa en gain Lo e e al. (2022). Resea che s ha e
employed di e en app oaches in an a emp o unde s and he causes o cos o e uns.
One line o in es iga ion is o obse e a pa icula indus y o manage ial mechanism
and glean he speci ic o echnical aspec s o ha indus y o mechanism ha esul in
cos o e uns. Fo example, in unneling p ojec s, Pa aske opoulou and Bou sis (2020)
showed ha inal cos s a e s ongly a ec ed by p elimina y g ound in es iga ions. In
ansi p ojec s, Gao and Tou an (2020) examined di e ences be ween hea y and ligh ail,
inding ha he o me su e ed conside ably mo e cos o e uns han he la e . Was y and
Nassa (2021) discussed p ojec delays and cos s emana ing om deba able issues be ween
he con ac o and he employe .
Ano he app oach is a sys ema ic obse a ion o cons uc ion p ojec s and en e p ises
h ough in e iews, wo kshops, and ques ionnai e su eys. The p oduc o his in es i-
ga ion was an in en o y o possible causes. Fo example, Famiyeh e al. (2017) su eyed
consul an s and con ac o s om six y go e nmen school p ojec s in Ghana. Simila ly,
Rosen eld (2014) analyzed esponses om wo hund ed p ac i ione s in he Is aeli cons uc-
ion indus y.
In pa allel o hese wo app oaches, ano he line o in es iga ion has eme ged, a guing
ha a mo e undamen al unde s anding o he o ces a play is needed. This app oach
is mo e s a egic in i s na u e, a o ing in ui i e easoning and ocusing on he s a egic
mo i a ion o s akeholde s o e he ac ical aspec s o he p ojec o he business en i on-
men . Two main heo ies ha e aken his cou se: he hiding hand hypo hesis da ing back o
Hi schman (1967) and he planning allacy, o iginally p oposed by T e sky and Kahneman
(1974) and la e championed by Fly bje g (2016) in he con ex o capi al p ojec s as a
coun e o he Hiding Hand.
Acco ding o he hiding hand hypo hesis, he planne s’ igno ance in he e y ea ly

p ojec . Thus, he hiding hand is a bene olen hand ha allows us o eap bene i s ha
would o he wise no be ealized. In con as , Fly bje g e al. (2002) a gued ha cos
o e uns in la ge capi al p ojec s a e he esul o in en ional mis ep esen a ion a he
easibili y s age, which lies wi h which p ojec p omo e s seek o con ince decision-make s
o ob ain p ojec app o al. Acco ding o his explana ion, he hiding hand is any hing bu
male olen and ins i u ional checks and balances a e needed o es ain i . In a simila
pessimis ic one, Loca elli e al. (2017) a gued ha he cons uc ion managemen li e a u e
igno es he elephan in he oom, i.e., co up ion. Fly bje g (2016)’s c i icism o he hiding
hand i sel was hea ily c i icized by Anheie (2016); Ika (2018); Lo e e al. (2019b). Al hough
Lo e e al. (2019a) ques ioned whe he ei he he hiding hand o he planning allacy a e
es able, hey a e epea edly used as ounda ional heo ies o imp o emen in p ojec
managemen Ika e al. (2020); Lo allo e al. (2023).
The s a egic beha io (o misbeha io ) in he planning s age is bu a p elude o
he s a egic in e ac ion in he ende ing s age. Low-bid ende s, pa icula ly in public
p ojec s, a e adi ionally he mos widesp ead bidding me hod o in as uc u e and
cons uc ion p ojec s, e.g., El-Sayegh e al. (2021); Onsa igo e al. (2020). The need o
gua an ee anspa ency, publici y, and equal oppo uni y in public p ocu emen demands
clea p ocedu es o be ollowed by bidde s, ende ing he low-bid me hod op imal om
a legal pe spec i e Awwad and Ammou y (2019). The low-bid me hod may esul in
highe cos s han he compe i i e p ice, such as when collusion happens Signo e al.
(2023). Howe e , his is ue wi h almos any bidding mechanism, and wi h p ope sc u iny,
collusion a emp s could be de ec ed Signo e al. (2020a).
No wi hs anding illegal collusion, low-bid ende s ha e been c i icized o ailing
o selec he bes alue bid Balles e os-Pé ez e al. (2015). In pa icula , low-bid ende s
equen ly esul in a phenomenon known as he winne ’s cu se. This was i s epo ed by
Capen e al. (1971), who ound ha auc ion winne s in he oil indus y consis en ly ecei ed
lowe e u ns on in es men compa ed o hei ini ial expec a ions. The winne ’s cu se has
since been ound in a e y wide ange o business se ings, including cons uc ion con ac s
(see Gia and Mi elman (2023)).
Consequen ly, al e na i e ende ing me hods ha e been p oposed. Fo example, addi-
ional c i e ia o he han he bes p ice ha e been adop ed by a ious public agencies whe e
a o mula inco po a ing c i e ia conce ning p ice, echnical, and o ganiza ional conside -
a ions de e mines he bes bid W. C. Wang e al. (2013). Ano he app oach o quali ying
he low-bid me hod is p esn ed by Signo e al. (2020b), who sugges ed ha only bids
abo e an “i esponsible bid h eshold” should be accep ed. Simila ly,
Che an e al. (2018)
p oposed a wo-s age auc ion p ocess wi h mul iple a ibu es ha allows he clien o
design an app op ia e bid-sco ing o mula. O he al e na i es include he second low-bid
me hod and he a e age-bid me hod. See, o example, Awwad and Ammou y (2019), who
ound ha om he clien ’s pe spec i e, he below-a e age-bid me hod is p e e ed o less
compe i i e p ojec s, whe eas o highly compe i i e p ojec s, he second low-bid me hod
is p e e ed. Balles e os-Pé ez e al. (2015) candidly concluded ha in he cu en s a e o

2.2. P ojec Managemen in he Cons uc ion Indus y
I is un o una e ha despi e he g ea in es men in imp o ing p ojec managemen ,

Y. Wang e al. (2019) s udied how con ac s a e used o cu b oppo unism and dis in-
guished be ween “ha d” and “weak” o ms o oppo unism. While many s udies ocus

Yao e al. (2023)

iola ions, and unila e ally assumed spi i iola ions.
2.3. Game Theo y Models
The bidding p ocess has been equen ly modeled using game heo y, e.g., by Budde
and Minne (2015); Lo en ziadis (2016). In pa icula , he winne ’s cu se phenomenon is
explained and analyzed using game heo y echniques (see Kagel and Le in (2002)). Fo
cons uc ion p ojec s, Ahmed e al. (2016) conside ed he compe i ion in mul is age bidding,
whe e he gene al con ac o who submi s he bids employs subcon ac o s o he ac ual
cons uc ion. Ba ough e al. (2012) used he p isone ’s dilemma and he chicken game o
acili a e he esolu ion o con lic s in cons uc ion p ojec s. The p isone ’s dilemma was
simila ly u ilized by Ho and Hsu (2014) o explain how o imp o e cons uc ion ende s ha
a e cha ac e ized by high bid p epa a ion cos s. Kembłowski e al. (2017) used no mal- o m
noncoope a i e games o model he bidding p ocess o a highway cons uc ion p ojec
om he bidde ’s pe spec i e.
Cos o e uns we e in es iga ed by Can a elli e al. (2013) using a game heo y
signaling model. They demons a ed ha misguided signaling leads o cos o e -
uns.
Peldschus e al. (2010)
used game heo y o selec an op imal cons uc ion si e.
San C is óbal (2015) used a model based on game heo y in o de o iden i y he ac i i ies
ha a e esponsible o he delays in cons uc ion p ojec s and o help guide PMs in dealing
wi h p ojec delays. All hese pape s used single-pe iod games. In con as , Shang and
Abdel Aziz (2020) de eloped a wo-pe iod game o assis public agencies in designing

The ubiqui y o cos o e uns in cons uc ion p ojec s sugges s ha hese ou comes

3. Model Backg ound
Ou model builds on a case s udy by Gia and Mi elman (2023) conduc ed in he
Depa men o Enginee ing and Cons uc ion (DEC), a la ge public o ganiza ion in Is ael.
The DEC employs PMs who o e see he cons uc ion o p ojec s by con ac o s a e a
low-bid ende ing p ocess. They analyzed a da a se o 148 low-bid cons uc ion p ojec s
and con i med he pendulum e ec desc ibed abo e: on a e age, he winning bid was 8%
lowe han he expe cos es ima e, whe eas he inal paymen o he con ac o was 16%

Depending on p ojec complexi y, manage ial s uc u es in DEC can di e signi ican ly,
encompassing a ange o di e se membe s, posi ions, esponsibili ies, and hie a chies.
Ne e heless, he pendulum e ec emained consis en ac oss di e en p ojec complexi ies.
The e o e, i is a gued ha he s a egic in e ac ion can be simpli ied o h ee membe s:
PMs, con ac o s, and he PA. Ul ima ely, he PM’s app o al is necessa y o he con ac o
o be ewa ded beyond hei binding o e . A guably, such decisions a e shaped by he
egula ions and no ms es ablished by he PA, he p essu es imposed by he con ac o , and
he incen i es and pe sonali y o he PM.
Löws ed and Räisänen (2012) emphasized he impo ance o quali a i e s udies and
subjec i e na a i es in unde s anding o ganiza ional beha io . The e o e, we complemen
he backg ound o ou model wi h in o mal subjec i e na a i es om expe ienced senio -
le el PMs om DEC. Via a social app, we sen he ollowing ques ion:
In he cons uc ion indus y, he ollowing global phenomenon has been iden i ied: con ac o s
win ende s wi h o e s ha a e below ma ke alue bu , a he comple ion o he p ojec , a e ewa ded
abo e ma ke alue. How do you explain his phenomenon?
Below a e exce p s om answe s ha we ecei ed:
•
“In he beginning o a p ojec , all in ol ed in he p ojec a e awa e o he eali y ha
he winning bid is well below ma ke alue. This unde s anding makes i easie o
PMs and hei supe iso s o app o e addi ional claims. This dynamic esul s in he

• “Con ac o s a e ained o ind loopholes in ende s, and will bid low assuming ha

is, e en when he design is op imal and igo ous, changes in p ojec s a e una oidable.
Ul ima ely, a leas some o he claims a e jus , o in he g ey a ea. Mos PMs will yield

•
“The cons uc ion indus y has in o mally accep ed cos o e uns as a eali y, and
highe managemen is ocused on ge ing p ojec s comple ed. In some cases, usually
wi h young PMs wi h li le expe ience, hey will play ough wi h he con ac o .
Howe e , a some poin , hey will con o m o he no m and app o e special claims
made by he con ac o . Ei he because hey unde s and ha o he wise hey will ail

•
“The p i a e sec o selec s con ac o s acco ding o hei p e ious epu a ion. Public

•
“This eali y exis s no only in he cons uc ion indus y. E e y h ee yea s, ca e ing

PMs we e hen asked o espond o a second and inal ques ion:
Wha is he in luence o a lenien e sus s ic app oach when managing a con ac o in
a p ojec ?
The ollowing a e exce p s om esponses o his ques ion:
•
“A s ic app oach can be bene icial in si ua ions whe e he con ac o has a his o y

in some cases he PMs app oach has a limi ed impac on p ojec ou comes”.
•
“A lenien app oach may os e be e collabo a ion be ween he PM and he con ac o ,
leading o a mo e posi i e wo king en i onmen . Howe e , i could also esul in cos

•
“A s ic app oach can help main ain con ol o e he p ojec budge and imeline,

may s ain he ela ionship be ween he PM and he con ac o , po en ially leading o

•
“A balance be ween leniency and s ic ness is c ucial. A PM should be lexible enough
o accommoda e necessa y changes o unexpec ed challenges, while s ill ensu ing ha
