Construction Materials and Indicative Prices for Lombok Projects

Material planning is a critical step in Lombok construction projects. Availability and cost vary across the island, so investors should work with verified suppliers and maintain clear specifications. Below is a practical overview of selected materials and indicative prices for 2025. These figures are for budgeting purposes only and should be confirmed before procurement.

Timber and Formwork Components

Timber remains essential for formwork and certain architectural finishes. Based on recent references:

• Balok Kayu Bekisting (Formwork Timber Beam): Rp 1,704,344 per m³
• Balok Kayu Kelas I (Class I Timber Beam): Rp 8,432,450 per m³
• Balok Kayu Kelas III (Class III Timber Beam): Rp 6,162,175 per m³

Practical Note:

Higher-grade timber is recommended for structural or exposed elements. Lower grades may be used for temporary formwork but require proper oiling to prevent moisture absorption.

Roofing Sheets and Accessories

Roofing selection impacts durability and maintenance cycles in Lombok’s coastal climate.

• Seng Gelombang 2.40 (Corrugated Zinc 2.40 m): Rp 59,685 per sheet
• Seng Gelombang BJLS 0.25 mm (1.8 × 0.8 m): Rp 70,610 per sheet
• Sepandek Warna 0.25 × 1 m (Colored Spandek): Rp 39,110 per meter

Tip:

Thicker profiles and proper coating reduce corrosion risk. Always match ridge and gutter 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 Ø4": Rp 389,000 per meter
• Pipa PVC Tipe AW Ø2": Rp 115,000 per meter
• Tee PVC dia 4" × 3": Rp 422,729 per pcs

Practical Note:

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

Flooring and Wall Finishes

Ceramic and granite tiles are widely used in villas and resorts for aesthetics and durability.

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

Tip:

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

Practical Note:

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.
