Key Considerations for Laboratory Construction: Prioritize Planning and Quality

2026-04-13 11:01

The construction of a physicochemical laboratory is a complex systems engineering project that spans multiple disciplines, including architecture, environmental science, and facility design. Scientific planning, rigorous construction, and standardized acceptance procedures are essential to ensuring the laboratory operates smoothly once it is completed.

Requirements Analysis: Conduct a Comprehensive Assessment and Define Clear Objectives

The first step in laboratory construction is a thorough needs analysis. It is essential to clearly define the laboratory’s functional purpose: is it for teaching and practical training, research and exploration, or testing and service provision? Different purposes entail significantly varying requirements for facility configuration and environmental conditions. Next, compile a comprehensive list of testing items to determine the types and quantities of instruments and equipment needed. Finally, assess the size of the staff and the workload to estimate the required space.

On-site surveys must not be overlooked. For the renovation of existing buildings, it is essential to ascertain fundamental conditions such as structural system, floor-to-floor height, load-bearing capacity, and the locations of utility pipelines. For new construction projects, factors such as site selection, building orientation, and the surrounding environment must be taken into account. All requirements should be documented in writing to serve as the basis for subsequent design work.

Solution Design: Collaborative Advancement by a Professional Team

The schematic design phase requires close collaboration among multiple disciplines. The architectural team completes functional zoning and circulation planning; the HVAC team designs the ventilation and air-conditioning system; the electrical team plans power supply, distribution, and lighting; the plumbing and drainage team lays out water piping networks; and the building automation team designs the intelligent systems. Close coordination among all disciplines is essential to prevent clashes between services and ensure that no functional requirements are overlooked.

The design process shall fully solicit input from end-users. Laboratory management personnel and frontline testing staff shall participate in the proposal review and provide recommendations from a user-centric perspective. The design proposal shall undergo multiple rounds of review and revision to ensure it meets actual operational needs. The design drawings shall be detailed and comprehensive, providing an accurate basis for construction.

Materials and Equipment: Quality First, Rigorous Quality Control

The selection of materials for laboratory construction directly affects both performance and service life. For wall surfaces, use antibacterial, mildew-resistant, and corrosion-resistant color-coated steel panels or inorganic pre-coated panels; for flooring, install anti-static, seamless, and jointless PVC material; the laboratory worktop should be selected from corrosion-resistant materials appropriate to the nature of the operations.

For critical equipment such as fume hoods, air-handling units, and ultrapure water systems, select well-established brands and reputable suppliers. Review product test reports and certification documents, and conduct on-site inspections of manufacturers and demonstration projects when necessary. Upon arrival at the job site, unpack and inspect the equipment, verify model and specification details, and check for any visible damage or defects.

Construction Management: Process Control Ensures Quality

Quality control throughout the construction process is of paramount importance. Cleanroom construction requires strict control of dust generation, with tight sealing of color-coated steel panel joints and proper rounding at all corners. Ventilation duct fabrication and installation must comply with relevant codes and standards, and air-leakage tests must pass. Wire and cable specifications must meet design requirements, connections must be correct and secure, and identification markings must be clear and legible.

Construction progress is rationally scheduled, and concurrent operations are coordinated in an orderly manner. Acceptance records for concealed works are complete, and photographs of pipeline routes are taken and archived to facilitate future maintenance. Change management is standardized: any modifications must be approved by the design team and documented in a written change notice.

Debugging and Testing: Performance Verification Achieved

Upon completion of construction, system commissioning and performance testing shall be carried out. For the ventilation system, commissioning shall balance airflow at each supply and exhaust outlet and measure face velocity in fume hoods. For the air-conditioning system, commissioning shall verify temperature and humidity control as well as differential pressure regulation, while cleanroom testing shall confirm compliance with the designated cleanliness class. For the purified water system, water quality parameters shall be tested; for the gas supply system, pressure and purity shall be inspected.

All test data shall be recorded and archived as the basis for acceptance. Non-conforming items shall be promptly rectified until they meet the design requirements. Testing instruments shall be calibrated to ensure the accuracy and reliability of the data.

Delivery and Commissioning: Training Completed, Operations Running Smoothly

Prior to the laboratory’s commissioning, comprehensive training shall be provided to both management and operational personnel. The training shall cover ventilation system operation, temperature and humidity settings, use of emergency equipment, and operation of the building automation system, among other topics. Only those who pass the training assessment may assume their duties.

Establish a comprehensive as-built documentation package, including design drawings, change records, product manuals, test reports, operation manuals, and other relevant documents. Maintain both electronic and hard-copy versions of the archives to facilitate future reference.

Develop operation and maintenance procedures that specify the content and frequency of routine inspections, and establish a fault reporting and repair process. Enter into maintenance contracts with equipment suppliers to ensure timely response.

Industry experts emphasize that laboratory construction is a long-term investment, and the foresight of planning and design, the controllability of construction quality, and the rigor of acceptance and commissioning all jointly determine the laboratory’s service life and operational performance. Only by maintaining strict quality control at every stage can a high-quality laboratory be built—one that stands the test of time.
