From breaking ground to the final handover, a successful project depends on meticulous planning, precise execution, and the ability to bring a vision to life in a controlled and structured manner.

Having recently commenced the construction of a 400,000+ square foot (2300+ tons) shed building for a factory, I’ve experienced firsthand the intricate dance between project planning and actual site execution. In this article, I will walk you through the essential construction steps for building an industrial factory shed and discuss how strong project control and leadership play pivotal roles in transforming the idea from inception to reality.

Inception: The Foundation of Success

Like any major project, the construction of an industrial shed begins long before the first shovel hits the ground. It starts with planning and design, the cornerstone of any successful construction project.

1. Conceptualization and Feasibility Study

Every project begins with an idea. During the conceptualization phase, the client’s vision is translated into a blueprint through collaboration between architects, engineers, and project managers. A feasibility study is conducted to determine the project’s viability in terms of technical, financial, and regulatory considerations. This phase also involves selecting the location, determining building size, and estimating costs.

2. Project Planning and Budgeting

Once the concept is finalized, the detailed project plan is developed. This includes:

• Defining project scope.
• Estimating timelines.
• Allocating resources.
• Setting up a baseline schedule and budget.

Clear objectives are set, and all stakeholders align on expectations regarding timeframes, costs, and quality. At this stage, permitting and regulatory approvals are secured to ensure compliance with local zoning laws, environmental regulations, and safety standards.

Construction: Bringing the Plan to Life

Constructing an industrial shed or Pre-Engineered Building (PEB) with heavy machinery foundations in Bangladesh requires precise civil engineering and an understanding of local soil conditions and climate. After the groundwork has been laid, the actual construction begins Here’s a data-driven step-by-step breakdown of how an industrial factory shed is constructed:

1. Pre-Construction: Site Survey & Design Planning

• Site Analysis: Conduct detailed soil testing, as Jamalpur has a mix of alluvial soil types. The soil bearing capacity in the region typically ranges from 120-180 kN/m2.
• Building Area: The industrial shed design will cover an area of 350,000 to 450,000 sq. ft., which requires careful structural design to accommodate the large span.
• Design Layout: Collaborate with local engineers to design the shed, incorporating BNBC (2020) guidelines, while considering: Wind loads: Up to 150-180 km/h due to occasional tropical storms. Seismic considerations: Jamalpur falls in seismic zone 2, requiring moderate earthquake resistance measures. Machinery load: Plan for machinery weighing up to 100 tons, requiring specialized foundations.

2. Excavation and Earthwork

• Excavation Depth: Based on soil conditions in Jamalpur, excavation for the machine foundation may go down to 4.5 meters for heavy equipment, while general building footings will be around 1.5-2.5 meters deep.
• Compaction: Compaction of the base to 95% SPD is essential for both building stability and long-term performance of the foundations, especially considering potential flood risks in Jamalpur.
• Grading: Provide appropriate grading with a slope of 1.5-2% to avoid water accumulation, crucial due to the region's high rainfall during the monsoon season.

3. Foundation Work

A. Shed Foundation: Footing, Short Column, and Grade Beam Construction

• Footing: For a shed of this size (350,000 to 450,000 sq. ft.), isolated footings are designed to support steel columns. Footing depth will generally range between 1.5-2.0m depending on soil capacity and building load.
• Short Column: After the footing is cast, short columns (up to 1.5m) are constructed to transfer loads from the structure. These columns are reinforced with 12-16mm TMT bars (Fe500 grade or higher).
• Grade Beam: Once the short columns are in place, grade beams are installed to connect the footings and provide structural integrity. The beams are generally 300-500mm wide and are reinforced with rebar (16-20mm diameter) to manage both axial loads and lateral forces.
• Waterproofing: Apply waterproofing membranes along the grade beams and footings to protect against ground moisture intrusion.

B. Machine Foundation: Deep Reinforced Concrete Foundation

• Excavation for Machine Foundation: Excavation for heavy machinery is taken to a depth of 4.5 meters to accommodate the massive dynamic and static loads.
• Reinforcement: The machine foundation requires heavy reinforcement with 25-32mm steel bars, arranged in multiple layers for enhanced strength. Concrete used for this foundation should be M35 or higher to support the machinery's operational forces.
• Vibration Isolation: For heavy machinery, vibration isolation pads or other damping systems are installed beneath the foundation to minimize the impact of dynamic loads on the structure and the equipment itself.

4. Erection of Steel Structure

• Anchor Bolts: Install anchor bolts with a ±2mm tolerance to secure the steel columns to the footings.
• Steel Columns and Rafters: Erect primary steel columns, typically 400-600mm sections, using cranes for precision. Rafters are connected to the columns to form the basic frame of the PEB structure.
• Purlins and Sag Rods: Install purlins and sag rods to support the roof structure. Purlins are typically Z- or C-sections and spaced according to wind load calculations (typically 1.5-2m apart).

5. Roofing and Wall Cladding

• Roof Sheeting: Use galvanized steel sheets with a thickness of 0.45-0.50mm, common in Bangladesh, to protect against corrosion due to high humidity. Ensure a roof slope of 5-10% to handle heavy monsoon rains in Jamalpur.
• Wall Cladding: For insulation and durability, use sandwich panels or metal sheets with insulation to maintain thermal comfort inside the building, given the temperature variation from 10°C in winter to 35°C in summer.
• Ventilation: Install ridge vents and louvers to ensure airflow. Given Jamalpur's humid environment, proper ventilation is crucial to prevent overheating of machinery.

6. Heavy Machinery Foundation and Floor Casting

• Floor Thickness: For areas housing heavy machinery, the floor thickness is typically 200-300mm, reinforced with TMT bars. Concrete grade should be M30-M35, capable of supporting heavy static and dynamic loads.
• Machine Foundation Load Capacity: The reinforced concrete foundation is designed to bear up to 500-1000 kN/m2, ensuring that it can handle both the weight and vibration of heavy industrial machinery.
• Precision Leveling: The floor must be leveled with a precision of ±5mm, especially around machine foundation points, to ensure operational efficiency.

7. Finishing and Internal Systems

• Electrical Systems: Install a 3-phase power system with adequate load handling capacity, ranging from 400-800 kVA, depending on the machinery’s electrical requirements.
• Plumbing and Drainage: Design drainage systems with a minimum slope of 1% to avoid water stagnation, particularly important due to Jamalpur’s high rainfall (annual rainfall: 1,800-2,500mm).
• HVAC Systems: Install appropriate HVAC systems designed for industrial settings. Given the local climate, aim to maintain indoor temperatures between 25-30°C, using both mechanical ventilation and natural airflow strategies.

8. Final Testing and Commissioning

• Load Testing: Perform static and dynamic load tests on the machine foundation to ensure the floor can withstand the heavy loads and vibrations. The foundation should handle up to 100 tons of machinery.
• Structural Integrity Tests: Conduct non-destructive testing (NDT) and laser alignment checks to ensure the structure is stable and safe according to the Bangladesh National Building Code (BNBC 2020).

The construction of an industrial shed of 350,000-450,000 sq. ft. in BANGLADESH typically takes 10-15 months, depending on scale and complexity. With effective Project Control and project leadership it is possible to complete such project within 5 to 8 months. PEB structures can reduce overall construction costs by 20-30%, and accelerate timelines by 30-40%. The shed is designed to handle machinery weighing up to 100 tons, with floor load capacities of 500-1000 kN/m2 to ensure durability under operational conditions.

By following this construction methodology, tailored to the specific conditions in Jamalpur, Bangladesh, your industrial shed will be built to last, withstanding both environmental challenges and heavy machinery demands. Adherence to BNBC standards ensures safety and structural integrity for long-term operations.

Project Control: The Engine Behind Success

While the construction of an industrial shed involves multiple stages, project control ensures that every step is executed with precision and on schedule. Effective project control involves the continuous monitoring and adjustment of key parameters such as time, cost, and quality.

1.???? Baseline Planning, Execution Monitoring and Reporting

A strong baseline plan is the foundation of project control. It maps out the entire process, from excavation to the final touches, and sets expectations for the timeline, budget, and resources. Using project control software (Microsoft Project, Primavera P6), construction managers can track progress against the baseline schedule and budget. Monitoring actual progress against this plan is crucial to identify deviations early and take corrective actions before issues escalate. This allows for real-time reporting and swift corrective action when deviations occur. Transparent communication with stakeholders is crucial, keeping them informed about project status, risks, and any adjustments made along the way.

2.???? Risk Management

Every construction project comes with risks—whether it’s weather delays, material shortages, or labor challenges. Project controls involve proactive risk management strategies to mitigate potential delays and cost overruns. Having a robust risk management plan in place ensures that potential issues are anticipated and mitigated. With proper foresight and contingency planning, potential setbacks can be minimized or avoided entirely. By regularly conducting risk assessments, the project team can stay ahead of potential disruptions.

3.???? Resource Management and Cost Control

Keeping costs in check is a critical element of project control. This involves managing labor, materials, and equipment efficiently to avoid waste or overspending. Effective resource management ensures that every piece of material and every hour of labor is used optimally. By continuously assessing the allocation of resources, project controls help to avoid waste and ensure the construction stays within budget.

Leadership in Construction: The Difference-Maker ?

While project controls provide the structure, effective leadership brings the human element to the forefront of construction management. Good project leadership is the key to aligning the workforce with the project’s goals and ensuring seamless communication across teams. Here’s how effective leadership makes all the difference:

1. Clear Communication A construction project involves multiple teams working in tandem. From engineers and architects to contractors and laborers, each has a role to play. Good leaders facilitate clear, open communication channels, ensuring that everyone is aligned and any issues are addressed quickly.
2. Decision-Making and Problem-Solving Construction is dynamic, with challenges arising at every phase. A leader who can make swift, informed decisions based on real-time data is invaluable. Whether it’s adjusting timelines, re-allocating resources, or modifying design plans, decisive action can keep the project on track.
3. Motivating the Team Construction projects can be long and arduous. It’s easy for teams to lose momentum, especially in the face of setbacks. A leader who motivates their team, keeps morale high, and fosters a sense of collaboration will drive better results. Recognizing and rewarding progress can inspire the team to push through challenges.
