Construction Materials and Price References for Lombok Projects

Material planning for villas, resorts, and commercial buildings in Lombok requires clear specifications and verified suppliers. Below is a practical overview of commonly used items with indicative prices for 2025. These figures are for budgeting purposes only and should be confirmed before procurement.

Concrete and Aggregates

Concrete strength depends on clean aggregates and controlled mix ratios. Indicative prices:

• Ready Mix Concrete: Rp 1,232,435 per m³
• Pasir Beton (Concrete Sand): Rp 513,225 per m³
• Kerikil Beton (Concrete Pebbles): Rp 350,000 per m³

Practical Note:

Ensure aggregates are free from clay and organic matter. For ready-mix, confirm batching plant location and delivery schedule to avoid cold joints.

Structural Steel and Profiles

Steel reinforcement and profiles form the backbone of structural integrity. Examples:

• Besi Beton Ulir (Deformed Rebar): Rp 17,255 per kg
• Besi Beton Polos (Plain Rebar): Rp 16,217 per kg
• Besi Siku 50 × 50 × 5 mm: Rp 240,000 per meter

Tip:

Request mill certificates and verify dimensions before installation. Store steel off the ground and under cover to prevent corrosion.

Roofing Sheets and Accessories

Roofing must withstand Lombok’s coastal climate and heavy rainfall. Indicative prices:

• Seng Gelombang Besar BJLS 25: Rp 90,811 per sheet
• Sepandek Warna 0.35 × 1 m: Rp 58,665 per meter
• Bubungan Ridge “Starter”: Rp 57,361 per pcs

Practical Note:

Thicker sheets and proper coating reduce corrosion risk. Match ridge accessories to sheet profiles for watertight installation.

Plumbing and PVC Components

Water supply and drainage systems rely on pressure-rated PVC pipes and fittings:

• Pipa PVC Tipe AW Ø3": Rp 234,000 per meter
• Pipa PVC Tipe AW Ø2": Rp 115,000 per meter
• Elbow PVC AW 3": Rp 15,000 per pcs

Tip:

Confirm pressure class and joint integrity during installation. Pressure testing before handover is standard practice.

Flooring and Wall Finishes

Ceramic and granite tiles are widely used for aesthetics and durability:

• Keramik Lantai Kamar Mandi 20 × 20 cm: Rp 77,838 per m²
• Granit Polished 60 × 60: Rp 177,030 per m²
• Marmer B1 40 × 40: Rp 363,718 per m²

Practical Note:

Ensure slip resistance ratings for wet areas and batch consistency to avoid color variation.

Hardware and Accessories

Door and window hardware must be specified by brand and model for consistency:

• Door Closer ex. DEKKSON DCL 300 HO: Rp 212,436 per pcs
• Cylinder Door Lock ex. DEKKSON DC DL 60 mm: Rp 84,469 per pcs
• Engsel Pintu (Door Hinge): Rp 35,000 per set

Tip:

Hardware quality affects long-term maintenance. Stainless or coated finishes are recommended for coastal environments.

Compliance and Documentation

All materials should be supported by certificates (SNI or equivalent) and delivery records. This documentation is essential for PBG approval and SLF issuance after completion. Inspectors often check conformity between installed materials and approved specifications.

Pricing Disclaimer (2025)

All prices listed are indicative as of 2025 and based on internal procurement references. Costs in Lombok vary by location, supplier, and logistics. Remote areas or projects requiring urgent delivery may experience higher prices. Always confirm current rates and specifications before ordering.
