31. A Step-by-Step Guide to Factory Construction: A Detailed CMS Analysis Free Download

This drawing set represents a comprehensive and visual Construction Method Statement (CMS) for the construction of an industrial workshop. It systematically outlines the methods and steps required, from groundbreaking to the completion of the roof structure.

Below is a detailed description following the construction phases as illustrated in the drawings.

Phase 1: Preparatory and Foundation Works

This initial phase focuses on site preparation and the construction of the building’s foundation.

1. Overall Site Layout: This drawing shows the general layout of the construction site, including the workshop’s location, internal access roads, the main entrance, and the exit route to National Highway 5. It serves as the master plan for all site activities.

2. Earthworks and Foundation Excavation Method: This details the excavation methods: manual digging for confined spaces and mechanical excavation using excavators for large foundation trenches. It also includes details on labor safety for workers in excavated pits.

3. Pile Installation Method: 

• Pile Installation Sequence: The site plan illustrates the sequence and path of the pile driving machine to install all foundation piles according to the design.
• Pile Pressing Machine Details: This provides a specific layout for a static pile pressing station, including the position of the press machine, counterweights, and the service crane

4. Setting Out and Pile Cap Construction:

• Gridline and Coordinate Setting Out: This drawing describes the use of surveying equipment (theodolite) to accurately establish the project’s gridlines, reference points, and the precise location of each pile head (Image 2).
• Pile Cap Formwork: Detailed cross-sections show the assembly of formwork for the pile caps (the concrete structures that link the pile heads together).
• Anchor Bolt Installation: This details the placement and securing of anchor bolts into the pile cap before concrete pouring. These bolts are critical for connecting the steel columns to the foundation.

Phase 2: Superstructure Works (Columns, Frames, Walls)

After completing the foundation, this phase focuses on erecting the main structural elements and enclosure walls.

1. Main Structural Frame Erection: This drawing illustrates the method for lifting and erecting the main steel (or concrete) frames of the workshop. Typically, two mobile cranes work in tandem to ensure safety and precision.

2. Column and Scaffolding Method:

• Scaffolding Tower Structure: Details the structure of a scaffolding tower used for support and access during column construction.
• Column Formwork: Details the formwork structure for concrete columns.

3. Masonry Wall Construction Method: This describes the technical requirements for building brick walls, including details on mortar joints, connections to columns, and the complete wall structure from the foundation up.

4. Logistics and Crane Movement: A diagram shows the typical movement path of a crane on-site for lifting and installing structural components.

Phase 3: Roofing Works

This is the final phase of completing the building’s envelope.

Roof Purlin Installation Method:

• 3D Perspective View: A highly intuitive 3D isometric drawing shows the installation sequence of purlins (the secondary members that support the roof sheeting) onto the main frames. It also details workers operating from a temporary work platform.
• Construction Plan View: This is the 2D plan corresponding to the 3D view, clearly showing the structural grid, purlin spacing (7500mm), and the direction of work. The drawing also specifies the use of temporary suspended work platforms for workers to move and operate at height.

Summary

This drawing set is a complete and professional Construction Method Statement. It presents a clear, logical, and detailed overview of the entire process for building an industrial workshop, from sub-grade works to the completion of the structural frame and roof. It serves as a critical guidance document for the engineering and construction team on site.
