“…The calculation of the material needs, the analysis of wages, and the total of the necessary tools are generated from the three coefficients. The composition of wages, materials, work, and equipment are determined, multiplied by materials, wages, and tool prices prevailing in the market (Abdullah et al, 2019). Analytical products are formed from activity data confirmed as the Indonesian National Standard (SNI).…”

In building construction, interior wall finishing work usually uses conventional methods, namely plastering and nat grout. At Cattleya Tower Sakura Garden City Apartment, East Jakarta, the unit wall finishing uses a more modern method: Stick on wall. The Stick on wall method uses alternative finishing materials other than plaster and nat grout as a hebel wall covering made of large boards covered with thick paper which must be glued with a glue-like material to the hebel walls. The use of this method in the apartment case aims to speed up the project construction process because 90% of the units in Cattleya Tower have been sold, so the completion of the project must be realized immediately. This study was conducted to evaluate the effectiveness in terms of cost and time of the Stick on wall finishing method compared to the plastering and nat grout method. By calculating using the SNI method and considering other aspects such as transportation from the supplier to the project site, it is known that wall finishing work using stick on wall is 0.74% cheaper than wall finishing work using plaster and nat grout. As for the comparison of work time, work using stick on wall is 74.58% faster than wall finishing work using plaster and nat grout with a difference in working time of 52 days. Keywords: Stick on wall; wall finishing; plastering cost; nat grout Abstrak Dalam konstruksi bangunan, pekerjaan finishing dinding interior biasanya menggunakan metode konvensional yaitu plesteran dan nat grout. Di Cattleya Tower Sakura Garden City Apartment, Jakarta Timur, finishing dinding unit menggunakan metode yang lebih modern: Stick on wall. Metode Stick on wall menggunakan bahan finishing alternatif selain plaster dan nat grout sebagai penutup dinding hebel yang terbuat dari papan besar yang dilapisi kertas tebal yang harus direkatkan dengan bahan sejenis lem pada dinding hebel. Penggunaan metode ini pada kasus apartemen tersebut bertujuan untuk mempercepat proses konstruksi proyek karena di Cattleya Tower tersebut unit yang telah terjual sebesar 90%, sehingga penyelesaian proyek tersebut harus segera direalisasikan. Studi ini dilakukan untuk mengevaluasi efektivitas dari segi biaya dan waktu dari metode pekerjaan finishing dinding Stick on wall dibandingkan dengan metode plesteran dan nat grout. Dengan menghitung menggunakan metode SNI dan mempertimbangkan aspek lain seperti transportasi dari pemasok ke lokasi proyek, diketahui bahwa pekerjaan finishing dinding menggunakan stick on wall lebih murah 0,74% dibandingkan pekerjaan finishing dinding menggunakan plesteran dan nat grout. Sedangkan untuk perbandingan waktu pengerjaan, pekerjaan menggunakan stick on wall lebih cepat 74,58% dibandingkan pekerjaan finishing dinding menggunakan plesteran dan nat grout dengan selisih waktu kerja adalah 52 hari.

“…The productivity of ceiling formwork is examined in publications. The productivity of masonry work is documented by Desale, V. and Deodhar, V. [77] Plastering work was the subject of a number of publications [78,79] in which comparable performance was achieved. The results of the average values of tiling work were presented by Idiake, E.J.…”

An integral part of managing the construction of investment units is the monitoring of labor productivity using statistical methods in combination with construction software. Such a combination includes a number of methods and modeling, among which is a method for determining the probability of the completion of construction processes based on the recorded mean value of labor productivity and its variations. For investment units consisting of two or more objects, it is necessary to assess the probability of the completion of construction processes related to follow-up activities and which are carried out by the same work crews. Based on the selected probability modeling, the aim of this contribution was to show how statistical methods and software support can contribute to savings in resources, both human and time, in construction production. The aspect is documented in a case study of residential buildings. The Lindeberg–Lévy and Moivre–Laplace theory and the Bernoulli principle were used for mathematical modeling. The CONTEC construction software was applied as the software support. The performed modeling showed a decrease in the mean value of performance for all the processes examined compared to the planned values, except for the implementation of reinforced concrete monolithic structures. For these reasons, the working capacities had to be increased in order to meet construction milestones.

Monitoring labor productivity and how to decrease construction costs are the key issues in the planning process of a construction project. The CONTEC automated system combined with statistical methods assists in predicting the amount of time required to complete construction works according to the specified number of deployed work crews, technological processes, and labor required for certain production in person-hours. This study applies statistical analyses and probability theories for plastering work, which represents a labor-intensive construction process. The goal of the research is to determine the probability of completion of the construction process based on monitoring the mean value of performance. By application of statistical analyses a decrease in the performance standard has been proved compared with the planned values given in the CONTEC database. The decrease in performance, which was also caused by the number of days with unfavorable climatic conditions and demonstrated by performing interval estimates based on the collection of statistical data, was later confirmed by a relative frequency test. The measures taken were in terms of establishing the required number of personnel capacities for complying with the construction schedule.
