Article: Method Statement for Warehouse Construction

1. Introduction

The construction of a warehouse is a complex process that demands precise planning, robust engineering, and adherence to safety and quality standards. This warehouse construction method statement provides a step-by-step guide covering all essential aspects — from site preparation to handover — ensuring the project is completed efficiently, safely, and in compliance with Saudi Building Code (SBC), ASTM, and ACI standards.

For contractors like Dorar Tammam Contracting (DTC), BoldTarget, and other leading companies in the Eastern Province, Dammam, Khobar, Riyadh, and Jeddah, method statements serve as the backbone of every industrial and PEB warehouse project.
