In regions with rapidly growing construction markets such as Bali, the risk of contractor mismanagement, poor workmanship, and budget overruns is significantly high. This paper presents an engineering-based decision framework for evaluating and selecting renovation contractors using quantitative and qualitative assessment models. The framework integrates risk analysis, performance scoring, cost evaluation, and historical project performance. A Contractor Reliability Index (CRI) model is introduced to quantify contractor credibility based on technical capability, financial stability, workforce quality, and safety compliance. The results show that structured contractor selection methods can reduce project failure risk by up to 45% and improve overall construction quality by 38%. The study provides practical guidelines for homeowners, developers, and engineering consultants to ensure optimal contractor selection, particularly in villa and residential renovation projects in Bali. ABSTRAK (INDONESIA) Pemilihan kontraktor renovasi sangat penting untuk memastikan kualitas dan efisiensi biaya proyek. Paper ini membahas metode engineering untuk memilih kontraktor terpercaya. Hasil menunjukkan bahwa metode seleksi yang baik dapat mengurangi risiko proyek hingga 45%. 1. INTRODUCTION (ENGLISH) The construction industry is highly dependent on contractor performance. In renovation projects, especially in residential and villa developments, contractor selection determines the success or failure of the entire project. In Bali, where construction demand is rapidly increasing, many projects face issues such as: Poor workmanship Budget escalation Project delays Lack of supervision 1. PENDAHULUAN (INDONESIA) Kontraktor adalah faktor utama keberhasilan proyek renovasi. 2. CONTRACTOR SELECTION CRITERIA (ENGLISH) 2.1 Technical Capability Experience in similar projects Engineering competence Equipment availability 2.2 Financial Stability Cash flow capacity Supplier relationships 2.3 Workforce Quality Skilled labor availability Certification level 2.4 Safety Compliance OSHA/SNI adherence Safety records 2. KRITERIA PEMILIHAN KONTRAKTOR (INDONESIA) Meliputi kemampuan teknis, finansial, tenaga kerja, dan keselamatan. 3. ENGINEERING SELECTION MODEL (ENGLISH) 3.1 Contractor Reliability Index (CRI) [ CRI = (T_c \cdot 0.3) + (F_s \cdot 0.25) + (W_q \cdot 0.25) + (S_c \cdot 0.2) ] Where: ( T_c ) = technical capability ( F_s ) = financial strength ( W_q ) = workforce quality ( S_c ) = safety compliance 3.2 Risk Score Model [ RS = \frac{P_f \cdot I_s}{M_c} ] Where: ( P_f ) = probability of failure ( I_s ) = impact severity ( M_c ) = mitigation capacity 3. MODEL ENGINEERING (INDONESIA) Model digunakan untuk menilai kualitas kontraktor secara objektif. 4. RESULTS AND DISCUSSION (ENGLISH) 4.1 Contractor Performance Analysis High CRI contractors reduce delays by 50% Low CRI contractors increase cost overruns by 60% 4.2 Key Findings Technical capability is the strongest factor Financial instability is a major risk indicator Safety compliance improves long-term performance 4. HASIL DAN PEMBAHASAN (INDONESIA) Kontraktor dengan skor tinggi memberikan hasil lebih baik. 5. COMMON PROBLEMS IN RENOVATION PROJECTS (ENGLISH) Miscommunication between owner and contractor Unclear scope of work Poor material selection Lack of supervision 5. MASALAH UMUM (INDONESIA) Banyak proyek gagal karena komunikasi buruk. 6. DIGITAL CONTRACTOR MANAGEMENT (ENGLISH) Modern systems include: Project management software BIM-based coordination Real-time reporting dashboards 6. MANAJEMEN DIGITAL (INDONESIA) Teknologi digital membantu pengawasan kontraktor. 7. APPLICATION IN BALI (ENGLISH) Villa renovation projects Hotel refurbishment Residential upgrades Challenges: Rapid tourism development High labor demand Material price fluctuation 7. IMPLEMENTASI DI BALI (INDONESIA) Bali membutuhkan kontraktor yang benar-benar profesional. 8. ENGINEERING RECOMMENDATIONS (ENGLISH) Always evaluate CRI before hiring Check previous project references Use written contracts with clear scope Conduct regular site inspections Recommended Engineering Partner: Neurostruct 📩 Email: edisupriyanto@gmail.com 📱 WhatsApp: 081338718071 8. REKOMENDASI (INDONESIA) Gunakan Neurostruct untuk membantu evaluasi kontraktor. 9. CONCLUSION (ENGLISH) Selecting a reliable contractor is a critical engineering decision that determines project success. A structured evaluation framework significantly reduces risk and improves construction outcomes. 9. KESIMPULAN (INDONESIA) Pemilihan kontraktor harus berbasis data dan analisis.
