This research article examines the process of producing and procuring construction materials during the reign of King Mongkut (1851-1868), through the collection and analysis of primary archival materials. The findings are (1) there were 6 types of construction materials : wood, brick, lime, stone, tiles, and metals; (2) most of the materials were still procured through traditional corvee system, while some needed to be purchased. The procurement process relied upon a detailed tally system, not unlike that which was used in the control of corvee labor; (3) local production of construction materials was craft-based rather than industry, using manual labor in major steps. Raw materials such as firewood, clay, or limestones, were obtained locally, so the production process was controlled by natural cycle; (4) a major factor was the locations of raw materials, and the transport from those places to the construction sites, many of which were provincial cities such as Ayutthaya, Phetchaburi, Nakhon Chaisi, Saraburi, Lopburi, and Songkhla; (5) transportation route and the new sources of materials remained attached to waterways such as rivers, canals, or even the sea.
