Abstract
In this modern era, high-rise buildings could be found in various countries. Every
construction of high-rise building has some risks that need to be noticed, because
high-rise building construction has weight work and height structure. This study
discusses the risk analysis on the work of upper structure formwork in building
projects to improve quality performance. The research problems for this study are
the determination of risk analysis standards and the formwork method used, factors
and variables, dominant risk analysis, and recommendations for improvement. For
risk standards, formwork methods, and factors & variables are analyzed by
literature studies and field studies. Furthermore, for the dominant risk analysis is
are analyzed by surveyed the main contractors to identify the frequency of risks and
the impact on quality performance. There are analyzed by Analytical Hierarchy
Process (AHP) to get the level of risk. The objective of analysis is to find the
dominant risks, which is a risk variable that marked as high level. The standard
used in this study is the Project Management Body of Knowledges (PMBOK), and
the formwork method used is the formwork system. The risk factors used for analysis
in this study consist of non-technical aspects, technical aspects, and legal aspects.
Non-technical aspects have variables that discuss about labor, equipments, and
materials. Technical aspects have variables that related to the execution and method
of formwork. The last factor is the legal aspects that discuss about construction
regulations and environmental regulations. The result of this study have found eigth
risk variables that give affect for quality performance, those are feasibility of
column/shearwall formwork after use (X.20), low construction costs (X.14), improper
age of equipment (X.6), change order design (X.15), joint tightness of
column/shearwall formwork (X23), marking of the column/shearwall position with
shop drawing (X17), change of foreman and labor (XI6). This study provides
recommendations for improvements to the dominant risk in structural formwork
work on building projects. For variables XI 4, X6, XI 3 can be avoided by makr a
good plan before the project runs. For XI 5 variables, the risk can be minimized by
asking the owner to issue Site Instruction if there is additional work. For variable
XI 6, risk can be reduced by giving special attention by supervisors and quality
control. For XI 7, X20, andX23 these risks can be avoided through a checklist before
the concrete work process with the consultant. / Pada era modem ini, bangunan gedung bertingkat tinggi dapat ditemukan di berbagai
negara. Setiap Pembangunan gedung bertingkat tinggi memiliki risiko yang perlu
diperhatikan, karena konstruksi bangunan gedung bertingkat tinggi memiliki bobot
pekeijaan yang besar dan struktur bangunan yang tinggi. Penelitian ini membahas
mengenai analisis risiko pada pekerjaan bekisting struktur atas pada proyek gedung
dalam rangka meningkatkan kinerja mutu. Permasalasahan penelitan untuk penelitian
ini adalah penentuan standard analisis risiko dan metode bekisting yang digunakan,
factor dan variabel, analisis risiko dominan, dan rekomendasi perbaikan. Untuk
standard risiko, metode bekisting, dan factor & variabel dianalisis dengan cara studi
literature dan studi lapangan. Sedangkan analisis risiko dominan dilakukan dengan
cara dengan cara survei kepada kontraktor utama untuk mengidentifikasi frekuensi
risiko dan dampak terhadap kinerja mutu. Keduanya dilakukan analisis dengan
Analytical Hierarchy Process (AHP) untuk mendapatkan tingkatan risiko. Analisis
tersebut bertujuan untuk menemukan risiko dominan, yaitu variabel risiko yang
memiliki tingkat high . Standard yang digunakan penelitian ini adalah Project
Management Body of Knowledges (PMBOK), dan metode bekisting yang
digunakan adalah metode bekisting system. Faktor yang digunakan untuk analisis
terdiri dari aspek non teknis, aspek teknis, dan aspek hukum. Aspek non teknis
meliputi variable yang membahas perihal tenaga kerja, perlatan, serta material.
Aspek teknis meliputi variable yang terkait pelaksanaan dan metodenya. Sedangkan
aspek hukum membahas mengenai legalitas hukum dan lingkunganHasil penelitian
ini didapati bahwa 3 varabel risiko yang memilki level High yang berdampak
terhadap kinerja mutu. Varibel itu antara lain Kelayakan bekisting kolom/shearwall
bekas pakai (X20), Biaya konstmksi yang rendah (X14), Usia alat yang tidak layak
(X6), Perubahan design (X15), Durasi pelaksanaan yang tidak wajar (X13), Kerapatan
sambungan bekisting kolom/shearwall (X23), Kesesuaian marking posisi
kolom/shearwall dengan shop drawing (X17), pergantian mandor dan tenaga kerja
(Xi6). Penelitian ini memberikan rekomendasi perbaikan untuk risiko dominan pada
pekerjaan bekisting struktur atas proyek gedung. Untuk variabel X14, X6, X13 dapat
dihindari dengan rencana yang matang sebelum proyek berjalan. Untuk variabel X15,
risiko dapat diperkecil dengan meminta owner menerbitkan Site Instruction apabila
terdapat pekerjaan tambah. Untuk variabel Xi6, risiko dapat dikurangi dengan
memberikan perhatian khusus oleh supervisor dan quality control. Untuk X17, X20,
dan X23 risiko tersebut dapat dihindari dengan melalui ceklist sebelum pelaksanaan
pengecoran bersama konsultan MK.
