ABSTRACT

The progress of construction work has different deviations at a

certain point in time. Various factors cause inequality. A

positive progress deviation indicates that construction work is

completed faster where the progress of the plan is lower than

the actual one, otherwise it is said to be late if it is negative.

The uncertain nature of construction work causes there are 3

(three) scenarios of possible progress deviation values, so that

these three values form one expected progress deviation value.

A deviation of value greater than negative 10% for a duration

from 0 to 70% is categorized as a critical contract. The purpose

of this study was to determine the deviation of the progress of

29 construction works. Data collection was carried out on 29

construction works that had been carried out. The data is taken

directly from the contractor. The results of data analysis

showed that at 10% D, 11 construction works with poor

performance were obtained. Information was also obtained

that the construction work No. 12 have critical contracts (-

11,773). Furthermore for the current construction work 30%D.

50% D and 70% D number of poorly performing construction

works 12; 10; and 9. The value of the largest positive progress

deviation is 15,362 at the 70% time point D. The expected value

of the largest positive progress deviation is positive 1,763. By

knowing the expected negative progress value, the contractor

must exercise control as soon as possible before the contract

expires. Acceleration can be done on activities that are on the

critical path.

INTRODUCTION

Work construction often experience delays that cause losses to contractors ,

consultants and owners good that time and money (Hassan et al., 2016) . Type

profession construction miscellaneous . one _ delivered is profession building

storied . High -rise buildings in general shared Becomes two , building graded low

and building graded high .

From the side contractor , lost time cause source power no could quick

drawn from location project . This cause happening swelling cost . Lateness be

measured with no the fulfillment of the work progress that has been planned in

schedule parent . Many factors cause _ why lateness occur (Mardiaman &

Indriasari, 2021) ; (Hassan et al., 2016) ; ( Shahsavand et al., 2018) . Lateness often

caused by contractor no capable provide appropriate funds with the progress of the

plan that has been compiled . Often an advance payment has been found given

diverted to project another . This occur because contractor work more from one

profession construction in time simultaneously . For prevent lateness contractor

must To do analysis the cause (Shahsavand et al., 2018) . Besides that must

identified factonrya (Asmi & Pratama, 2016) Stability finance must available for

finance profession construction . According to (Mardiaman, 2020) that criteria

stability finance Becomes most important criteria for choose contractor so that

profession construction can success . one _ success profession construction seen

from side suitability time plan .

Work progress construction could seen every period time . generally

evaluated every week at the time meeting weekly . Meeting weekly generally

attended element owners , consultants and contractors . On every meeting all

problem about achievement of progress and weekly targets discussed by together

according to ability . Target time customized with availability source power and

condition field. However resources that should provided no fulfill good from side

amount and quality.

In practice , progress can be experience deviation , fine positive and negative

. The deviation of progress is difference between plan and actual progress . The size

deviation is score results profession construction , Yield value Becomes criteria in

evaluation value performance _ vary . This value must traced (Amruta B. Vyas &

BV Birajdar, 2016) . Yield value is one _ technique control profession construction

(Suharto, 2007) ; ( Bhosekar & Vyas, 2012) . Time and costs incurred is reflection

achievement progress (Huda et al., 2018) .

Because of the nature profession construction that is not certain then

progress will be character probability , can fulfilled and not fulfilled . more and

more information obtained so level probability the more high , worth zero until with

one . There is progress pessimistic , most likely and optimistic , so that from all

three will shape one score hope for progress (Mardiaman & Kusuma, 2021) .

The purpose of this study was to determine the deviation of the progress of

29 construction works.
