This document discusses Design for Manufacture and Assembly (DFMA) for prefabricated buildings. It defines DFMA as an approach that optimizes design for efficient manufacturing and assembly. Applying DFMA principles such as minimizing components, standardizing parts, and designing for clarity can reduce costs, schedule, and improve quality, productivity, sustainability and safety. The document outlines benefits of DFMA including reduced cost, schedule and improved site safety. It also discusses the DFMA process and its application at different project stages, as well as risks that must be managed such as design, staff and operational costs.

3. PENGERTIAN DFMA
DfMA is a design approach that focuses on ease
of manufacture and efficiency of assembly.
By optimising the design of a product it is
possibleto manufacture and assemble it more efficiently, more
quickly, more safely and at a lower cost.

DFMA stands for Design for Manufacture and Assembly.
DFMA is the combination of two methodologies;
Design for Manufacture, which means the design for ease of
manufacture of the parts that will form a product, and
Design for Assembly, which means the design of the product
for ease of assembly deriving creative ideas at the same time.

6. PROSES DFMA
MINIMALISASI JUMLAH KOMPONEN, BIAYA, PROSES DAN OTOMATISASI YANG
SEDERHANA.
DESIGN YANG MEMPERMUDAH FABRIKASI DAN MENGHINDARI FEATURES
KOMPONAN YANG TIDAK DI PERLUKAN
TOLERANCES – KAPABILITAS PROSES DISESUAIKAN DENGAN DESIGN DARI KOMPONEN
PREFAB
DESIGN MEMUDAHKAN PERAKITAN – PRODUK DIRANCANG UNTUK MUDAH DIRAKIT
SECARA CEPAT DAN AKURAT.
CLARITY – KOMPONEN HANYA BISA DIRAKIT DENGAN SATU CARA.
MINIMALISASI KOMPONEN FLEKSIBEL - KARET, GASKET, KABEL, DAN SEBAGAINYA,
HARUS DIBATASI KARENA PENANGANAN DAN PERAKITAN UMUMNYA LEBIH SULIT.

10. CONLUSION
 DFMA dapat mewujudkan tercapainya target
biaya, waktu, mutu serta safety yang lebih baik
untuk dunia konstruksi.
 DFMA membantu mewujudkan sustainable
construction dengan waste yang lebih sedikit
pencemaran lingkungan lainnya.
 Pengerjaan DFMA pada pabrik lebih baik dari
sisi safety di bandingkan on-site construction
sehingga di dapatkan kualitas Kesehatan dan
resiko safety yang lebih baik.
 DFMA juga memilik resiko yang harus di manage
baik dari aspek design, sdm, biaya, serta
operasiona proyek
