For investors, cost optimization, schedule assurance, and quality control are always top priorities when deciding to expand production infrastructure. However, the traditional management approach, where the factory design unit and factory construction contractor are separated, often creates many shortcomings. Misalignment between technical drawings and actual site conditions not only extends the handover timeline, but also causes the budget to exceed the estimate due to unplanned additional costs.
To thoroughly resolve this risk, a synchronized implementation model managed by one general construction contractor is becoming an optimal solution for businesses. When the process from survey, cost estimation, and construction design to factory construction is continuously connected under one management point, investors can proactively control the schedule, reduce 15% to 20% of intermediary costs, and simplify all related legal procedures. In this article, BIC provides a detailed analysis of the economic and technical benefits, as well as the practical process that helps businesses make the most effective investment decision.
Many businesses still choose to sign independent contracts with two separate units: one responsible for construction design and another responsible for factory construction. In theory, this option helps investors separate supervision and consulting functions, but in practice, it creates many major issues.
- Conflicts between technical drawings and actual construction: Factory design consultants sometimes propose architectural or structural solutions that are theoretical and lack feasibility during erection. This forces the construction site to stop work while waiting for drawing revisions, wasting time and generating additional material costs.
- Responsibility shifting when problems occur: When a project encounters structural defects, schedule delays, or budget overruns, determining the root cause often becomes a cycle of blame. The contractor may claim that the design drawings are unreasonable or lack details, while the design unit may argue that the contractor used incorrect construction methods or the wrong material specifications.
- Higher management costs and schedule delays: The investor must act as the coordination bridge, spending significant time and manpower managing communication between the two parties. Poor synchronization in communication means on-site issues are not resolved immediately, delaying project handover.
To completely overcome the limitations of the traditional method, the synchronized implementation model, also known as the turnkey model, is becoming a new standard preferred by investors. In this model, one general construction contractor takes full responsibility for planning, geotechnical survey, factory design, legal procedures, structural fabrication, construction, and handover for operation.
- Optimizing design based on construction reality: Thanks to close coordination from the beginning among architects, structural engineers, and site management teams, construction design solutions always follow actual construction capacity, ensuring the highest feasibility and optimized material costs.
- Responsibility concentrated under one point of contact: The general contractor takes comprehensive responsibility for project quality, schedule, occupational safety, and budget. All technical problems or additional costs are handled by one unit, eliminating dispute risks among different parties.
- Shorter project handover timeline: Applying a synchronized model allows work stages to overlap continuously. While construction drawings are being completed, the general contractor can proactively order materials and fabricate pre-engineered steel frames at the factory, helping shorten the overall implementation timeline by 20% to 30%.
The synchronized implementation model helps businesses tightly control financial planning from the design stage. Construction design drawings are developed based on practical calculations of material prices, labor costs, and construction technologies at the time of implementation.
- Synchronized material solutions: The general construction contractor proactively selects optimal structural and material solutions that meet load and operational requirements without wasting resources.
- Reduced unplanned additional costs: Because the factory design has already considered construction feasibility, the risk of demolition, repair, or drawing changes midway through the project is minimized.
- Reduced intermediary management costs: The investor does not need to spend budget maintaining a large supervision team to coordinate among multiple independent contractors.
In manufacturing, earlier factory handover means businesses can bring cash flow into operation sooner. The turnkey model eliminates idle time between stages through overlapping implementation.
- Parallel implementation of work stages: While waiting for technical drawing approval or construction permit completion, the general contractor can already plan material procurement, survey the site, and fabricate pre-engineered steel frames at the workshop.
- Closed working process: Information flows directly between the design department and site engineers, allowing technical issues to be handled immediately without wasting time on multiple meetings or approval layers.
Beautiful drawings are only valuable when they can be accurately realized on-site. Close coordination between architects and construction engineers ensures that every design detail follows actual execution capability.
- Optimizing production line functionality: Factory design is accurately adjusted according to machinery positions, fire protection systems, internal roads, and floor loads, avoiding floor cracking or settlement caused by insufficient capacity after the factory enters operation.
- Synchronized quality supervision: The general contractor applies one consistent quality control system from steel selection, concrete, and fireproof coatings to the actual factory construction process.
One of the greatest pressures for investors when building production infrastructure is managing too many consulting units, subcontractors, material suppliers, and authorities.
- A single point of contact: The investor only needs to work with one project management representative from the general construction contractor to update progress, approve budgets, and accept each work item.
- Comprehensive responsibility belongs to the general contractor: All risks related to technical incidents, schedule delays, or occupational safety issues are handled and compensated by the general contractor according to contractual commitments.
Administrative procedures are a common barrier that delays factory projects from entering operation.
- Faster fire protection approval and construction permitting: A professional factory design unit that also performs construction understands current fire protection regulations, including QCVN 06:2022/BXD and related amendments. This helps prepare accurate design dossiers from the beginning and avoids repeated dossier rejection.
- Ensuring completion documentation conditions: Construction that closely follows the approved drawings helps the process of project acceptance, fire protection acceptance, and completion documentation for ownership registration proceed smoothly and on schedule.
A synchronized implementation process from project planning to handover goes through six closed steps under the direct coordination of the general construction contractor.
The general contractor conducts geotechnical drilling to determine soil bearing capacity, measures topography, and records the condition of surrounding infrastructure. Based on the company’s production needs, the engineering team prepares a master layout plan, dividing the factory area, office zone, internal roads, parking area, and auxiliary works.
At this step, the factory design team prepares architectural drawings, technology diagrams, structural solutions such as foundations, columns, beams, and steel rafters, as well as MEP infrastructure systems. Detailed construction design drawings help the investor visualize the entire building and provide the accurate basis for quantity takeoff and fixed cost estimation.
The general contractor represents the investor in preparing and submitting the construction permit application to the competent authorities. In parallel, the fire prevention and fighting design dossier is submitted to the Fire Police Department for approval. Having one unit perform the full scope helps quickly handle revision requests and ensures the project has sufficient legal conditions to start construction as planned.
Factory construction is carried out simultaneously on two fronts:
- At the construction site: Engineers carry out excavation, foundation caps, grade beams, column pedestals, and factory floor concrete works according to the structural design.
- At the fabrication plant: Steel frame components such as columns, beams, and purlins are fabricated, cut, automatically welded, sandblasted for surface cleaning, and coated with fireproof or anti-corrosion paint according to standards.
After the foundation concrete reaches the required strength and steel components are transported to the site, the general contractor uses specialized cranes to erect the pre-engineered steel frame. Next, the contractor installs metal roofing, wall cladding, windows, concrete floors with hardener finish such as Harilite or Quartz, or epoxy coating, and completes brick wall areas and paint finishes.
Power supply, lighting, water supply and drainage, ventilation, and automatic fire protection systems are completed and tested in integrated operation. The general contractor organizes internal acceptance, coordinates with competent authorities for fire protection acceptance and project acceptance, and hands over the factory to the investor for use, together with complete as-built dossiers and warranty documents.
Choosing the right general construction contractor determines up to 90% of the success, quality, and schedule of the entire project. To avoid the risk of working with underqualified contractors, investors should carefully evaluate the following core criteria.
Businesses need to verify the Construction Activity Capacity Certificate issued by the Ministry or Department of Construction, with Grade I, II, or III depending on the project scale.
- Capability profile: Evaluate similar industrial factory projects that the unit has implemented. A reputable general contractor will be willing to take investors to visit completed and operating projects in person.
- Personnel: Check the capability of the site manager, architects, structural engineers, and occupational safety supervision team, also known as HSE.
Modern industrial factories depend heavily on the quality of pre-engineered steel structures.
- Steel component fabrication plant: A general contractor that owns its own steel fabrication plant can fully control schedule, material origin, and input costs compared with units that outsource fabrication.
- Machinery and equipment: The contractor should have modern construction equipment such as mobile cranes, theodolites, laser floor screeds, load testing equipment, and industrial coating equipment.
The construction contract is the most important legal document protecting the investor’s rights.
- Schedule and penalties: The contract must clearly define completion milestones for each work item and specific penalties if handover is delayed for reasons other than force majeure.
- Detailed Bill of Quantities (BOQ): The quotation should specify each material type, brand, technical specification, and origin clearly.
- Warranty policy: A professional general contractor usually commits to a structural warranty of 5 to 10 years and periodic maintenance of M&E infrastructure systems for 12 to 24 months.
Most general construction contractors today apply preferential policies that reduce 50% to 100% of factory design costs when the investor signs a turnkey construction contract. This helps businesses save a significant budget from the project initiation stage.
The completion time depends on the project scale and complexity:
- Factories under 5,000 m²: Implementation time is about 2.5 to 3.5 months.
- Factories from 5,000 m² to 20,000 m²: Implementation time is about 4 to 6 months.
Thanks to the method of fabricating steel frames at the workshop in parallel with foundation construction on-site, the overall timeline is significantly shorter than traditional reinforced concrete construction.
When a synchronized solution is applied, the general construction contractor is the only unit fully responsible to the investor. Any issues related to roof leakage, floor cracking, structural defects, or fire protection, electrical, and plumbing system errors are directly received by the general contractor, who assigns engineers to handle them within 24 to 48 hours according to the warranty commitment in the contract.
In summary, choosing a synchronized factory design and construction solution is not only a short-term cost optimization decision, but also a strategy that helps investors control risks, ensure project quality, and put the factory into operation sooner.
