In the industrial and construction sectors, starting from scratch is not always the most efficient solution. Many businesses today prioritize renovating or upgrading existing factories and facilities instead of investing in completely new constructions. Choosing the right time for renovation can help significantly reduce costs, shorten construction schedules, and minimize production disruptions.
In fact, many existing structures can still meet operational requirements if properly assessed and renovated. Key factors such as structural durability, technical infrastructure, production expansion needs, and new standard requirements are crucial in deciding between renovation and new construction. For factories located in areas with well-developed infrastructure, renovation also enables businesses to leverage existing electrical, water, transport systems, and permits maximizing investment efficiency.
With years of experience in industrial factory design and construction, BIC accompanies businesses in assessing existing conditions, developing renovation plans, and executing construction with professionalism. We ensure that renovated projects not only meet technical standards but also deliver optimal operational efficiency. In the following article, BIC will help you determine when renovation is preferable to new construction, along with key technical, economic, and legal considerations before making an investment decision.
In industrial production, two common investment directions are renovating existing facilities and building new ones. Each option has distinct characteristics, costs, and objectives, depending on the factory’s condition, scale of operation, and business development strategy.
Renovation involves upgrading, repairing, or modifying the function, technical systems, or layout of an existing structure without completely demolishing it. This method is typically applied when the factory’s load-bearing capacity, infrastructure, and location remain suitable for production.
In contrast, new construction involves building a completely new facility with brand-new design, foundation, and technical systems. This approach is more suitable when the old structure is severely degraded, unsafe, or when major production expansion is required.
Nowadays, many businesses seek to optimize costs through renovation. Reusing existing foundations, structures, and infrastructure can save substantial investment expenses and shorten construction time. Renovation also allows continuous production, avoids disruption to orders, and reduces legal risks since existing buildings already hold valid construction permits.
Before deciding on an investment approach, it is essential to assess the current condition of the facility, including structural integrity, electrical and water systems, ventilation, and fire protection systems. A thorough assessment helps determine whether renovation will optimize costs or if new construction is necessary for long-term functionality and durability.
A professional design and construction team plays a decisive role at this stage. Experienced engineers can analyze survey results to propose technical, financial, and legal solutions that ensure the project’s quality, timeline, and cost-efficiency.
Deciding between renovation and new construction depends not only on investment costs but also on the technical condition, usage scale, legal compliance, and implementation schedule. Below are four key factors that businesses should evaluate for optimal, long-term efficiency:
Before deciding to renovate, accurately assess the load-bearing capacity and durability of key structural components such as the foundation, columns, beams, slabs, and steel frames.
- If these structures remain stable without cracks, deflection, corrosion, or subsidence, the building can safely undergo renovation and upgrading.
- However, if there are severe signs of deterioration (wide cracks, deep corrosion, sagging floors, or weak foundations), renovation poses safety risks and higher repair costs. In this case, new construction is the safer and more economical option for long-term use.
One of the most critical factors is the building’s intended use after completion:
- If the business plans to expand production, install automated lines, or increase load capacity, then new construction is more appropriate, as old structures often cannot meet modern technical requirements.
- Conversely, if the goal is to enhance existing functionality, such as rearranging layouts, adding offices, improving ventilation, lighting, or fire safety renovation is a cost-saving and time-efficient solution.
Accurately defining the new functional requirements prevents waste and ensures long-term operational suitability.
Legal compliance plays a pivotal role:
- If the business intends to change usage purpose, expand floor area, or increase building height, a new construction permit and design appraisal are mandatory.
- If the renovation only involves internal layout changes or technical upgrades without affecting structural integrity, the business may proceed without reapplying for permits, simply notifying local authorities or the industrial park management.
It is also important to review zoning and land-use limits to ensure compliance with development plans and construction boundaries.
Economic efficiency is the core criterion for all investment decisions.
- Renovation costs typically account for 30–50% of the cost of new construction, since much of the existing foundation, structure, and infrastructure can be reused.
- Renovation also shortens construction time by 40–60%, allowing faster operation resumption and minimizing production interruption.
In contrast, new construction often requires more legal procedures and longer timelines due to demolition, site leveling, foundation work, and system inspections.
Therefore, the decision between renovation and new construction should be based on a comprehensive cost–benefit analysis, including total investment, payback time, and technical risks.
Not every old building needs to be replaced. In many cases, strategic renovation yields higher investment efficiency especially when businesses wish to maintain stable production and utilize existing infrastructure. Renovation is recommended in the following situations:
If the foundation, columns, and beams still have sufficient load-bearing capacity and show no major damage, renovation can save considerable construction costs and time.
Businesses seeking to improve lighting, ventilation, air conditioning, fire safety, or rearrange the workspace can benefit from renovation.
Renovation can be carried out in phases, allowing ongoing production in other areas—a key advantage for factories with continuous operations.
Renovating within a legally compliant, well-serviced industrial park avoids the need for new land leasing and permit applications.
Although renovation is economical and flexible, new construction becomes necessary when safety, functionality, or efficiency cannot be ensured otherwise:
- The structure is severely degraded and unsafe.
- Renovation costs exceed 60% of the cost of new construction.
- There is a major change in production technology or capacity (e.g., automation, GMP-standard facilities).
- The site is affected by urban redevelopment or zoning restrictions.
- The building cannot meet updated safety, fire, or environmental standards even after renovation.
In these cases, new construction ensures compliance with modern standards (ISO, LEED, GMP), enhances efficiency, and offers a longer service life—typically 30–50 years.

Through comparison, it can be seen that renovation is suitable for businesses that aim to optimize costs, make use of existing infrastructure, and maintain stable operations. In contrast, new construction is the ideal solution for projects targeting large-scale production, advanced technologies, or modern technical standards.
The choice of the optimal approach should be based on an evaluation of the current technical condition, development needs, financial capability, and the long-term investment strategy of each business.
A successful renovation project depends not only on investment costs but also on a systematic implementation process, strict technical supervision, and ensuring safety throughout construction. Below are five essential steps to help businesses carry out industrial renovation effectively, correctly, and economically.
Before starting, it is necessary to conduct a comprehensive assessment of the existing condition, including: load-bearing structure, foundation system, walls, roof, steel frame, electrical system, water supply and drainage, ventilation, and fire protection.
- The goal is to determine which components can be retained and which need replacement.
- Parameters such as floor deflection, column tilt, material strength, and load-bearing capacity must be measured using specialized equipment.
- The survey should be performed by a qualified industrial structural engineering unit to ensure accuracy and safety for subsequent renovation planning.
After receiving survey results, the design team will develop a detailed renovation plan and determine:
- Which items will remain unchanged, which will be reinforced, and which need to be replaced.
- Solutions to improve functionality, ventilation, lighting, noise control, or production layout.
- Calculation of new loads, building height, and integration of technical systems (electricity, water, exhaust, fire protection).
The renovation plan should clearly present objectives, work volume, schedule, and estimated costs, helping businesses easily compare renovation with new construction.
Depending on the project’s scale and nature, some major renovation projects (involving structural changes, floor area expansion, or additional stories) require official renovation permits.
- The design documentation includes technical drawings, construction method statements, structural calculations, and a list of materials.
- Permit applications are submitted to the Department of Construction or the Industrial Park Management Board, depending on the project’s location.
- If the renovation involves only interior work or auxiliary systems, businesses may proceed without reapplying for permits only notifying relevant authorities.
Complying with these legal requirements helps the project avoid suspension or penalties during execution.
During construction, appropriate site organization must be ensured to avoid affecting ongoing production activities.
- Construction should be carried out in phases, starting with areas that cause minimal disruption.
- Protective measures such as dust barriers, noise reduction, and strict adherence to occupational safety regulations must be implemented.
- All structural renovation work (column, beam, roof, or foundation reinforcement) must be continuously supervised by qualified engineers to ensure compliance with design and technical standards.
This phase also includes reinstallation and testing of electrical, plumbing, ventilation, lighting, and fire protection systems to ensure compatibility with the existing structure.
After completion, the project must undergo acceptance testing in accordance with technical regulations.
- Structural load capacity, durability, waterproofing, insulation, and operational safety must be inspected.
- For factories in industrial parks, fire safety and environmental acceptance reports are required before the facility is approved for use.
- As-built documentation and updated drawings must be prepared for record-keeping and future maintenance.
Proper acceptance and handover procedures not only ensure operational safety but also serve as essential legal documentation for enterprise asset management.
A well-executed renovation process allows businesses to maximize the value of existing assets, minimize downtime, reduce costs, and improve production efficiency.
Renovating factories or industrial facilities is not merely a temporary cost-saving measure. In many cases, it is a strategic investment that helps businesses optimize resources, improve building efficiency, and ensure sustainable development. Below are the main advantages renovation offers over new construction:
One of the most significant advantages of renovation is its substantially lower cost compared to new construction. By reusing existing foundations, frames, utilities, and infrastructure, renovation costs typically account for only 30–50% of a new project’s total investment.
Additionally, the implementation time is considerably shorter, enabling faster operation resumption and quicker capital recovery. While new construction may take 12 to 18 months, many renovation projects can be completed within 3 to 6 months, depending on scale and scope.
Unlike new construction, which often requires complete shutdown, renovation allows phased execution while maintaining operations.
Businesses can reorganize layouts, temporarily relocate equipment, or segment construction areas to minimize production disruption. This is particularly critical in industries requiring continuous operations such as mechanical manufacturing, food processing, logistics, or pharmaceuticals.
Many older facilities are located in advantageous areas near highways, ports, or within fully developed industrial parks. Renovation at such locations enables businesses to continue benefiting from existing electricity, water, drainage, wastewater treatment, and service infrastructure without the need for reinvestment.
Maintaining the same location also ensures supply chain and workforce stability, avoiding relocation costs and production delays.
Renovation allows functional improvement without complete demolition. Businesses can adjust layout, enhance ventilation, lighting, and sound insulation, or upgrade office spaces, canteens, and storage areas while retaining the main structure.
Some facilities can even expand by adding mezzanines, canopies, or auxiliary sections without compromising overall stability. This flexibility helps enterprises adapt quickly to production changes or expansion needs without significant additional investment.
Renovation significantly reduces construction waste and limits the consumption of new materials such as steel, concrete, and cement materials associated with high CO₂ emissions.
Reusing existing structures and materials, along with upgrading insulation and energy-efficient lighting systems, makes buildings more environmentally friendly and easier to meet green standards such as LEED, EDGE, or ISO 14001.
This approach is increasingly adopted by FDI enterprises to demonstrate social responsibility and commitment to sustainable development in Vietnam.
In a fast-changing market, many businesses need to modify production lines, product types, or technologies in a short time. Compared to new construction, renovation allows rapid adjustments to meet new production requirements, pilot new products, or increase capacity.
This flexibility provides strategic advantages enabling enterprises to seize market opportunities without being constrained by lengthy construction timelines.
In general, renovation is a smart and effective investment solution, especially for businesses seeking to optimize costs, maintain stable production, and enhance facility efficiency.
However, to ensure safety, durability, and consistency, renovation must be professionally designed, calculated, and supervised to balance cost, performance, and structural integrity.
The decision between renovation and new construction is not only a technical choice but also a strategic investment decision. Each approach has its own value:
- Renovation helps save costs, leverage existing assets, and maintain continuous production.
- New construction offers a synchronized, modern facility aligned with long-term development goals.
To achieve the best results, businesses should comprehensively evaluate the current facility condition, production needs, budget, and future expansion plans. A renovation or construction project is only truly successful when it ensures three key factors: structural safety, economic efficiency, and legal compliance.
Therefore, before making a decision, enterprises should seek assistance from professional design and construction consultants capable of conducting detailed surveys, technical planning, and accurate cost estimation. Having an experienced team involved from the beginning helps minimize risks, optimize costs, and ensure both technical and aesthetic quality.
