Site Works, Landscaping, and Ancillary Materials for Projects in Senggigi, West Lombok

For coastal areas like Senggigi, site works and landscape materials determine how well villas, resorts, and commercial buildings handle rainfall, salt exposure, and daily traffic. The items below are representative of what we procure locally, with indicative 2025 prices taken from internal lists. Figures are for planning only and should be revalidated before tender or purchase orders due to location-based logistics and stock variability on the island.

Earthworks and Fill Materials

Correct fill selection and compaction reduce settlement and protect hardscape finishes. Typical references:

• Tanah Timbunan (Fill Soil) — Rp 193,885 per m³
• Tanah Uruk (Backfill Soil) — Rp 324,325 per m³
• Tanah Urug Pilihan (Selected Fill) — Rp 227,028 per m³
• Sirtu (Sand–Stone Mix) — Rp 359,258 per m³

Sirtu Gunung/Alam (per truck) — Rp 130,365 per m³ (listed as “per truck” in source, plan by volume)*

Execution notes:

• Confirm moisture content and perform layer-by-layer compaction (e.g., 15–20 cm lifts).
• Use selected fill beneath paved areas; reserve general fill for landscaping mounds.
• Record compaction tests where required by drawings.

Aggregates and Base Course for Hardscape

Clean, graded aggregates are critical for base layers beneath paving and driveways:

• Kerikil Beton (max 30 mm) — Rp 350,000 per m³
• Batu Pecah Mesin 2–3 cm — Rp 449,758 per m³
• Batu Pecah Mesin 3–4 cm — Rp 426,086 per m³
• Batu Belah/Pondasi — Rp 259,460 per m³

In practice:

• Keep stockpiles covered to limit fines washing during rains.
• Check grading visually and avoid mixing wet and dry aggregates without adjusting water content in concrete or bedding layers.

Paving Blocks, Kerbs, and Edges

Traffic class and edge control determine long-term performance of external surfaces:

• Paving Blok Tebal 6 cm K100 — Rp 93,863 per m²
• Paving Blok Tebal 6 cm K200 — Rp 113,418 per m²
• Paving Blok Tebal 8 cm K300 — Rp 147,964 per m²
• Kansteen 20×40 (K200) — Rp 58,013 per biji
• Kansteen 30×60 (K300) — Rp 98,817 per biji
• Kanstein (standard reference) — Rp 71,702 per biji

Execution notes:

• Compact subbase to the specified density; use bedding sand of consistent gradation.
• Install edge restraints (kerbs or concrete haunching) to prevent lateral migration.
• Maintain falls to collection points, especially near stone façades to avoid splash‑back and staining.

Drainage Lines, Culverts, and Roof Water Integration

Drainage capacity must match rainfall intensity in coastal Senggigi:

• PVC RRJ Ø4″ (110 mm) — Rp 150,965 per meter
• PVC RRJ Ø6″ (160 mm) — Rp 313,153 per meter
• Buis Sigaran Ø30 cm × 1 m — Rp 173,386 per pcs
• Buis Beton dia 80 cm — Rp 100,509 per pcs
• Square PVC Gutter — Rp 55,000 per meter
• Talang PVC Kotak — Rp 71,702 per meter

In practice:

• Use compacted bedding and proper haunching around buried lines.
• Hose‑test roof gutters and downpipes before finishes; document tests for handover.
• Include sand traps or sumps at low points to reduce sediment build‑up.

Natural Stone and Landscape Finishes

Coastal aesthetics often rely on robust stones that tolerate salt and moisture:

• Andesite “Catur” (cladding) — Rp 202,067 per m²
• Palimanan Stone — Rp 189,030 per m²

Batu Koral (0.5–1 cm / 1–2 cm / 2–3 cm) — Rp 355,072 per m³ (size-specific references are similar)*

• Batu Kali Tempel/Keping (river stone tile/slab) — Rp 237,264 per m²

Execution notes:

• Use breathable sealers; avoid trapping moisture behind stone.
• Stainless or galvanized anchors are recommended to limit corrosion marks on façades.

---

Timber, Boards, and Site Formwork

Temporary works and some landscape fixtures use timber and boards:

• Balok Kayu Bekisting (Formwork Timber Beam) — Rp 1,704,344 per m³
• Papan Kayu Kelas II (Class II Board) — Rp 6,555,168 per m³
• Triplek 120×240×12 mm — Rp 215,103 per sheet
• Calsiboard 120×240×6 mm — Rp 129,730 per sheet

In practice:

• Apply formwork oil to reduce adhesion and moisture uptake.
• Store boards flat and off the ground; acclimatize prior to installation.

Water Handling Equipment (Site Use)

Reliable pumping helps during testing, landscaping, and temporary dewatering:

• Pompa Air (general) — Rp 1,950,000 per unit
• Pompa Air Sanyo — Rp 3,540,600 per unit
• Pompa Air Honda WB.30 — Rp 6,750,000 per unit
• Water Pump Kiong — Rp 1,948,956 per pcs
• Water Cooler + Hose Ø1 ¾ — Rp 1,238,467 per pcs

Execution notes:

• Log equipment capacities, hose diameters, and test records (e.g., pipeline pressure tests).
• Position pumps to avoid recirculating sediment into clean lines or basins.

Documentation, Testing, and Permits

• Specifications in contracts: Define grading for aggregates, paving class (K100–K300), kerb dimensions, pipe class (AW/RRJ), and stone type with finish.
• Supplier verification: Request SNI or equivalent certificates and delivery notes with batch IDs.
• On‑site checks: Density/compaction tests for subbase, hose tests for roof water flow, and visual inspections of jointing for PVC lines.
• Regulatory alignment: Maintain records to support OSS submissions, PBG approvals, and SLF after completion. Inspectors review installed outcomes against approved specifications and drawings.

Summary

For Senggigi projects, site works and landscaping depend on controlled compaction, clean aggregates, and correctly sized drainage. The materials and indicative prices above provide a working baseline. Discipline in specification, supplier documentation, and simple field tests reduces post‑construction maintenance and supports timely approvals for villas, resorts, and commercial buildings.
