The labor cost has a high proportion of the total cost of engineering and construction projects. Hence, labor productivity has to effect on the success of any engineering and construction projects. Installation of steel reinforcement bar, among others, is the most critical task. It is often adversely affected by the outdoor environment and other factors. This paper presents the measurement of labor productivity by work sampling method for floor and beams steel reinforcement bar of high-rise buildings in Ho Chi Minh City, Vietnam. The research identifies the proportion of time consumption for effective tasks, supportive tasks, and ineffective tasks of steel reinforcement bar as follows: 31%, 34%, and 35% respectively. In other words, its labor productivity variability is shown by the change in effective work over periods. It is low at the beginning and the end and is highest at the mid-shift working session.

Electrical Installation

Purpose The construction industry is a labor-intensive industry, hence, the presence of labor with high productivity at each stage of the project plays a significant role in achieving project success. The purpose of this paper is to provide real-life empirical data about the current level of construction productivity, in this case electrical installation work, within construction projects in Norway. In addition, it was of interest to identify the areas which have the highest potential for improvement of labor productivity. Design/methodology/approach This study considers the construction labor productivity through an elaboration on productive vs unproductive time within construction projects. It is based on a “frequency study” done on eight construction projects in Norway. The “work sampling” method has been used for collection of empirical data. For each project, four electricians were observed an entire working day and the amount of time they spent on performing each activity was recorded every 60th seconds. The activities observed were based on a predefined set of activities. Findings The results of the observations show that on average, 61.1 percent of the time was direct value-added work. This number is significantly better than what is normally discussed as being productive time. However, the findings also show that there is still potential for improvement. The activities that have the highest potential for improvement include “material transfer,” “amendments to already executed installation,” “personal needs” and “waiting times.” Practical implications The study results will be of immense benefit to managers of construction projects as well as managers of construction organizations in enhancing their project performance and productivity. Originality/value This paper contributes both theoretically and empirically to the current discussion and findings on labor productivity and its relation to project success. The results presented in this paper have important implications of labor productivity in construction projects and future studies in the area of project performance.

The Cost

Construction management is an effort in managing projects in the construction sector that goes according to planning, one of which is resource management which is included in the scope of construction management. To regulate the use of labor, the contractor must know the level of worker productivity. The productivity of workers will greatly affect the profit or loss of a project, this is because the level of worker productivity is related to the cost of wages for the realization of the labor required. To analyze this productivity, several methods can be used, including the Work sampling method. This method is used to determine how much labor productivity in the Sukabumi District Government Building Construction project on column work consisting of reinforcement work, formwork, and casting in this study. Research procedures carried out are starting with a literature study. This activity is carried out both before and after the researcher has successfully identified the problem. Then the field study (direct observation) by measuring the productivity of the workers doing the work, and taking the necessary data. In researching the field, the number of workers observed in this project was workers who worked from the beginning of the process until the completion of work in each area that was worked on. There are 5 workers with a duration of 10 days. From the calculation results, it is obtained that the standard time which also shows the amount of labor productivity in column work with concrete structures for reinforcement work is 3.907 kg/minute, then for formwork work is 11,951 / m2 and for casting work is 17,727 / m3. Then the labor coefficient is obtained for 0.065 OH for reinforcement work, 0.199 OH for formwork work, and 0.295 OH for casting work.Keywords: Labor, productivity, work samplingAbstrak : Manajemen konstruksi adalah upaya dalam mengatur proyek dalam bidang konstruksi bisa berjalan sesuai dengan perencanaan, salah satunya adalah manajemen sumber daya yang termasuk dalam cakupan dari manajemen konstruksi. Dalam upaya mengatur penggunaan tenaga kerja, maka kontraktor harus mengetahui tingkat produktivitas pekerja. Produktivitas pekerja akan sangat berpengaruh terhadap keuntungan atau kerugian suatu proyek, hal ini dikarenakan tingkat produktivitas pekerja berhubungan dengan biaya upah realisasi tenaga kerja yang diperlukan. Untuk menganalisis produktivitas ini ada beberapa metode yang bisa digunakan, antara lain metode Work sampling. Metode ini digunakan untuk mengetahui seberapa besar produktivitas tenaga kerja di proyek Pembangunan Gedung Pemda Kabupaten Sukabumi pada pekerjaan kolom yang terdiri dari pekerjaan pembesian, bekisting dan pengecoran pada penelitian ini. Prosedur Penelitian yang dilakukan adalah dimulai dengan studi literatur. Kegiatan ini dilakukan baik sebelum maupun sesudah peneliti berhasil mengindentifikasi masalah. Kemudian studi lapangan (pengamatan langsung) dengan melakukan pengukuran produktivitas terhadap pekerja yang melakukan pekerjaan, dan mengambil data-data yang diperlukan. Pada pelaksanaan penelitian di lapangan, jumlah pekerja yang diamati dalam proyek ini adalah pekerja yang bekerja dari awal proses hingga selesainya pekerjaan di setiap area yang dikerjakan. Pekerja yang diamatai sebanyak 5 orang pekerja dengan durasi 10 hari. Dari hasil perhitungan didapat waktu baku yang juga menunjukkan besarnya produktivitas tenaga kerja pada pekerjaan kolom dengan struktur beton untuk pekerjaan pembesian adalah 3,907 kg/menit, kemudian untuk pekerjaan bekisting adalah 11,951/m2 dan untuk pekerjaan pengecoran adalah 17,727/m3. Kemudian untuk koefisien tenaga kerja didapat sebesar 0.065 OH untuk pekerjaan pembesian, 0.199 OH untuk pekerjaan bekisting dan 0.295 OH untuk pekerjaan pengecoran.Kata kunci : Tenaga kerja, produktivitas, work sampling

The paper considers necessary conditions for acceleration of labor productivity growth in Russia. Based on micro data, as well as aggregate data, the paper quantifies the contribution of small and medium firms to labor productivity growth. It shows that mere increase of the number of small and medium enterprises is not as important for positive effects of these programs, as qualitative improvements: development of favorable environment for growth, which is largely determined by business climate. Accelerating productivity growth involves redistribution of labor and capital from inefficient to efficient enterprises. In particular, it is necessary to create conditions, which allow a firm to grow after it enters the market instead of stagnating as a small firm with low efficiency. At the same time, it is necessary for ineffective firms, which exhausted their growth potential, to have an opportunity to exit the market easily leaving resources including labor to fast-growing companies.

Productivity Gap

Using level accounting methodology this article examines sources of per capita GDP and labor productivity differences between Russia and developed and developing countries. It considers the role played by the following determinants in per capita GDP gap: per hour labor productivity, number of hours worked per worker and labor-population ratio. It is shown that labor productivity difference is the main reason of Russia’s lagging behind. Factors of Russia’s low labor productivity are then estimated. It is found that 33-39% of 2.5-5-times labor productivity gap (estimated for non-oil sector) between Russia and developed countries (US, Canada, Germany, Norway) is explained by lower capital-to-labor ratio and the latter 58-65% of the gap is due to lower technological level (multifactor productivity). Human capital level in Russia is almost the same as in developed countries, so it explains only 2-4% of labor productivity gap.
