What is specific about Jubail for general contracting & turnkey

Team note on Jubail: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Jubail is about 0.9 km from the sea coast (OpenStreetMap).

The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Jubail sits about 4 m above sea level, and it lies roughly 0.9 km from the coast. That combination of low elevation and close proximity to the Gulf means the air is humid and salty, and water can pool in low spots after heavy rain. For a turnkey project, this shapes the order of work. Drainage, external levels and waterproofing need to be checked before finishes are chosen, so that interior work is not damaged by water or salt moving in from outside. Surveys are planned to look at the site edges and external walls as well as the rooms themselves.

Those conditions also affect how we plan for the season. Before summer, we prioritise split AC supply and installation, which typically costs SAR 350–900 per unit, so units are running before the hottest weeks and any electrical or drainage issues are sorted early. Painting, plastering and tiling are timed to avoid the wettest periods, and surface preparation is included in the painting rate of SAR 8–25 per m², because salt-laden air makes poor preparation show up quickly. For a new annex or rest-house, building costs run from SAR 700–1,800 per m², and decor works from SAR 30–100 per m², so the budget can be split clearly between structure and finish.

Owners in Jubail often avoid the same few mistakes. The first is starting finishes before the site has been surveyed and measured, which is why a quantity survey at SAR 150–400 per visit is worth doing first. The second is choosing a fixed-cost plan without checking what full finishing to handover, at SAR 300–800 per m², actually includes. The third is ignoring the ceiling and wall details: gypsum board false ceilings at SAR 40–90 per m² and plastering with guides at SAR 15–35 per m² need to be agreed before work begins. Finally, many owners leave the rain and summer timing to chance. A turnkey plan that sequences the work around the site's real conditions avoids costly rework.

Checks before summer and before the rain season catch problems while they are still small.

Signs worth paying attention to

These are the signs most often linked to general contracting & turnkey:

• An owner who cannot follow the site daily
• Many contractors and no coordination
• A project that needs one party responsible

Causes we see in the field

• Changes with no record — we check this before anything else.
• No single schedule — we check this before anything else.
• No written scope.

Tools and methods, and when we use them

How the work is done, step by step

1. Survey and scope: The full scope is written.
2. Bill of quantities and schedule: Items, stages and dates are agreed.
3. Execution by stages: Each stage is checked before the next.
4. Handover: Final check, snag list and handover.
