Nanjing Expansion Technology – Professionally Undertakes Laboratory Planning and Design

Laboratory planning and design is by no means a simple spatial layout—it is, instead, a systematic process that integrates scientific research needs, safety regulations, and engineering technologies. For universities, research institutes, and corporate R&D centers, a scientifically sound and well-organized laboratory design not only enhances research efficiency but also fundamentally ensures the safety of experimental personnel and the stable operation of equipment. Nanjing Expansion Technology With more than a decade of deep expertise in laboratory planning and design, we have become a leading professional service provider in this field domestically—thanks to our precise understanding of industry challenges and our comprehensive, end-to-end service capabilities. To date, we've delivered tailor-made solutions to over a thousand clients.

In terms of the professionalism in laboratory planning and design, Nanjing Expansion Technology has always centered on "compliance, precision, and adaptability," building an irreplaceable service advantage through three key dimensions: team, standards, and processes.

1. Professional Team: Ensuring Design Aligns with the Essence of Scientific Research

At the heart of laboratory design lies the principle of "understanding scientific research"—only by deeply grasping the experimental processes and needs across various fields can we avoid mere theoretical discussions. Nanjing Expansion Technology's core design team boasts a unique dual expertise: on one hand, its key technical personnel each bring over ten years of industry experience, with an in-depth understanding of laboratory design and construction. They hold prestigious industry certifications such as Senior Laboratory Engineer, Laboratory Quality Manager, In-House Laboratory Auditor, Registered Metrologist, Registered HVAC Engineer, and Registered Construction Engineer, ensuring a solid foundation in engineering design. On the other hand, the team includes technicians who have previously worked in university research labs and CDC testing laboratories, giving them firsthand familiarity with the operational logic behind experiments in diverse fields like biology, chemistry, healthcare, and new energy.

Taking a biopharmaceutical laboratory project at a certain university as an example, the team discovered during their preliminary research that the client needed to simultaneously conduct both cell culture and drug synthesis experiments—processes with entirely different requirements for cleanliness, temperature, humidity, and gas environments. Leveraging their deep understanding of biological experimental workflows, the design team divided the lab into three major modules and meticulously planned separate pathways for personnel and materials flow, effectively preventing cross-contamination. This "research-savvy" design approach ensured that the proposed solution smoothly passed the review by both the client and the university's research administration department on the first attempt, eliminating the need for costly rework later on.

In addition, Nanjing Kuozhan Technology has established a "dedicated team for each project" service mechanism—each project is equipped with 1 lead designer, 1 research needs consultant, and 1 engineering implementation specialist, ensuring that the design solutions not only meet scientific research requirements but also align seamlessly with subsequent construction processes. The team boasts an average of over 8 years of industry experience and has collectively delivered services for more than 3,000 laboratory projects of various types. This enables them to swiftly respond to clients' personalized needs, such as designing explosion-proof circuit systems for new-energy material laboratories or configuring exclusive sample-preparation areas tailored specifically for food-testing labs.

II. Compliance Design: Strictly adhere to national standards to ensure successful acceptance.

The bottom line in laboratory design is "compliance." In recent years, the nation has continuously refined its regulatory requirements for laboratory construction—ranging from GB 50346-2011, the "Technical Code for Biological Safety Laboratory Buildings," to GB 50447-2019, the "Code for Laboratory Building Design," and further extending to specific guidelines issued by local environmental protection and disease control authorities. Any single instance of non-compliance could potentially bring a project to a standstill. At Nanjing Expansion Technology, we integrate "compliance" seamlessly into every stage of the design process, ensuring that clients can rest easy, knowing they’re fully prepared to meet rigorous验收 standards.

During the scheme design phase, the team will develop a customized "compliance checklist" tailored to the specific laboratory type:

• For biosafety laboratories (P2/P3 level), strictly design the negative-pressure system in accordance with GB 50346 requirements, ensuring unidirectional airflow from the clean area to the contaminated area. Additionally, equip dedicated interfaces for devices such as biosafety cabinets and high-pressure steam sterilizers, and reserve emergency exhaust ducts.
• For the chemistry laboratory, the primary focus is on ensuring compliance with the ventilation system standards, designed according to the criterion of "minimum airflow of ≥1200 m³/h per fume hood." Additionally, reagent cabinets and hazardous waste storage areas will be strategically placed near exhaust outlets to minimize the accumulation of harmful gases.
• For medical testing laboratories, it is necessary to comply with the "Administrative Measures for Clinical Laboratories in Medical Institutions," designing separate areas for sample reception, testing, and report review to prevent cross-contamination of samples.

In addition to following national standards, Nanjing Expansion Technology also proactively coordinates with local fire safety, environmental protection, and disease control departments to understand specific regional requirements. For instance, in a microbiology laboratory project at a provincial CDC, the team learned in advance that local regulations mandated "pre-treatment + secondary treatment" before laboratory wastewater could be discharged. As a result, they incorporated an integrated wastewater treatment system into the design plan and simultaneously reserved an online monitoring interface, ensuring that the facility would smoothly pass the environmental protection department’s inspection on the first attempt during the final acceptance process.

III. Customized Processes: Comprehensive Control Across the Entire Lifecycle—from Concept to Implementation

Laboratory design isn’t a “one-and-done” process—it’s one that requires deep communication with the client and repeated optimization. Nanjing Expansion Technology has established a "four-step customized process" to ensure that the solution precisely meets the client’s needs:

Step one: Demand Diagnosis. After the project kicks off, the dedicated team will visit the site for a 1-3 day research phase. During this time, they’ll not only assess the lab’s area, ceiling height, and existing structural features but also conduct in-depth interviews with laboratory staff and key personnel to clarify critical information such as "core experimental projects, equipment lists, staffing arrangements, and the development plan for the next 3 to 5 years." For instance, during a survey of a pharmaceutical company’s R&D lab, when the client mentioned potential future additions like high-performance liquid chromatographs and mass spectrometers—both sizable pieces of equipment—the team proactively incorporated design elements such as reinforced load-bearing foundations and dedicated power supply interfaces to accommodate these new instruments.

Step two: Scheme design. Based on the research findings, the team will deliver a preliminary plan consisting of a "Functional Zone Map + 3D Rendering + System Configuration List." The Functional Zone Map will clearly indicate the area and location of the experimental zone, auxiliary areas (such as changing rooms and buffer zones), and office spaces. The 3D rendering will give clients a vivid visual preview of the lab’s final appearance, while the System Configuration List will provide detailed specifications and recommended brands for ventilation, utilities, purification, and intelligent systems.

Step three: Solution optimization. The team will hold 2–3 solution review meetings with the client, quickly incorporating any adjustments requested by the client—such as changes to functional zoning or equipment placement. For instance, when a university’s chemistry lab client expressed a desire to increase the number of student workstations, the team addressed the request by optimizing aisle widths and reconfiguring the workstation layout, ensuring that safety distances were maintained while meeting the client’s needs.

Step four: On-site guidance. Once the plan is finalized, the designer will be fully involved throughout the construction process, visiting the site 1-2 times per week to ensure that the work strictly adheres to the design drawings. If any unexpected issues arise during construction—such as structural discrepancies from the design—the designer will provide an adjusted plan within 24 hours, preventing delays in the project timeline.

From a team that "understands scientific research," to designs that "adhere to standards," and finally to processes that "prioritize practical implementation," Nanjing Expansion Technology has consistently leveraged its professional expertise to create laboratory planning solutions that are "safe, efficient, and future-proof" for our clients. Whether you're a university research team, a medical testing institution, or an enterprise R&D center, choosing Nanjing Expansion Technology means opting for a "worry-free solution" in laboratory construction.
