Before anyone moves in, the university must define the science, assess protocol-specific hazards, verify the building’s structure and utilities, obtain institutional and regulatory approvals, install engineering controls, commission equipment and emergency systems, train users, and document occupancy authorization.
The safest sequence is: define the research envelope, complete a multidisciplinary risk and needs assessment, survey the existing building, build a costed business case, secure approvals, renovate infrastructure, install and certify equipment, then commission the facility before use.

What makes an unused building suitable for research?
A vacant building becomes a laboratory only when it can support the planned work safely, legally and reliably. “Small” describes scale, not reduced obligations. Even a few rooms may need controlled ventilation, dedicated electrical circuits, emergency power, secure chemical storage, biological containment, radiation controls, special waste handling, accessibility upgrades and documented operating procedures.

A teaching room for nonhazardous electronics has a different risk profile from a laboratory using volatile solvents, recombinant nucleic acids, human specimens, animals, radiation, pathogens, toxins or high-energy equipment. The project team should therefore avoid selecting rooms or buying instruments until it has written down what work will occur.

Define the research envelope
Prepare a one-page scope that states:
- Disciplines and research questions.
- Protocols, organisms, chemicals, radioactive materials and maximum quantities.
- Whether work involves human subjects, animals, pathogens, toxins, recombinant or synthetic nucleic acids, radiation or high-energy equipment.
- Number and type of users, staffing coverage, working hours and visitor access.
- Instruments, sample receipt and processing steps, storage conditions and utility demands.
- Material flows, clean and dirty routes, waste streams, pickup frequency and decontamination methods.
- Required security, access-control and data-protection measures.
This scope becomes the design brief for facilities engineers, environmental health and safety (EH&S), architects, procurement staff and regulators. If the research changes, the risk assessment and design must be revisited rather than quietly stretching the original assumptions.
Use a lifecycle business case, not a renovation wish list
The World Health Organization’s laboratory planning guidance treats refurbishment and repurposing as projects that require a business case based on risk and needs assessment. The business case should cover the entire lifecycle:
- Feasibility, surveys, design, permitting and professional fees.
- Enabling work, demolition, hazardous-material abatement and construction.
- Mechanical, electrical and plumbing upgrades, fire protection and access control.
- Casework, fixed equipment, movable instruments, furniture and information technology.
- Personal protective equipment (PPE), initial consumables and waste contracts.
- Training, standard operating procedure (SOP) development and commissioning.
- Validation, inspections, insurance, utilities, calibration, maintenance and eventual replacement.
A low construction bid can be misleading if it excludes service contracts, ventilation balancing, certification, permits, consumables or long-term maintenance. Present capital and operating costs together so the university can see the facility’s total ownership burden.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesSet decision gates
Use formal approval gates so that expensive work does not begin before risks are understood:
- Scope gate: The research envelope and user requirements are approved.
- Feasibility gate: Surveys confirm that the building can support the hazards, loads, utilities and flows, or identify the upgrades needed.
- Concept gate: The block plan, room data sheets, preliminary budget and approval path are accepted.
- Construction gate: Permits, design reviews, funding and contractor plans are complete.
- Occupancy gate: Commissioning records, training, inspections and deficiency closeout authorize use.
Perform a protocol-driven risk assessment first
The CDC/NIH Biosafety in Microbiological and Biomedical Laboratories (BMBL), sixth edition, updated March 18, 2026, identifies protocol-driven risk assessment as its core principle. The BMBL is advisory best practice rather than a regulation, but it provides a strong framework for deciding which controls a particular procedure requires.
Formal biological risk assessments should be completed before work begins and repeated whenever practices, personnel, instruments or facilities change. The same discipline should be applied to chemical, radiation, fire, electrical, ergonomic and security hazards.
Form the assessment team
Include the principal investigator and intended users, EH&S, biosafety and radiation-safety specialists where applicable, facilities and engineering, occupational health, finance and procurement, security, waste-management staff and representatives of maintenance. A multidisciplinary team catches conflicts that a single investigator may miss, such as an instrument that exceeds floor loading, a solvent process that overwhelms the exhaust system or a waste route that passes through public space.

Convert hazards into controls
For each protocol, document the hazard, exposure route, consequence, likelihood, required engineering control, administrative control, PPE and emergency response. Examples include:
- Volatile or toxic chemicals may require a properly designed and certified chemical fume hood, compatible storage, spill supplies and a chemical hygiene plan.
- Biological procedures may require a biosafety cabinet, directional airflow, decontamination and access restrictions appropriate to the assessed containment level.
- Radioactive work may require shielding, contamination monitoring, secure sources, dosimetry and radiation-safety approval.
- Compressed gases may require restrained cylinders, compatible regulators, ventilation, segregation and fire-prevention controls.
- High-energy or electrical equipment may require guarding, interlocks, grounding, lockout/tagout procedures and restricted access.
Do not use a room label such as “wet lab” or “BSL-2” as a substitute for a procedure-level assessment. The controls must match the actual agents, quantities, equipment and work practices.
Survey the unused building before buying equipment
Commission a documented existing-conditions survey by qualified facilities professionals. An empty room may look usable while its hidden infrastructure is inadequate or contaminated.
Building and structural checks
- Obtain as-built drawings and verify what is actually present.
- Check floor loading, point loads, vibration and anchorage for centrifuges, freezers, gas cylinders, shielding and other heavy equipment.
- Measure floor-to-floor height and ceiling space for ducts, services and maintenance access.
- Inspect walls, floors and ceilings for cleanability, moisture damage and penetrations.
- Identify asbestos, lead, mold, legacy chemicals or other contamination before demolition or intrusive work.
- Confirm loading-dock access, delivery routes, laydown space and routes for removing large instruments.
Mechanical and utility checks
- Measure HVAC outdoor-air, exhaust and makeup-air capacity; do not assume the existing system can support fume hoods or biosafety cabinets.
- Determine whether pressure relationships and airflow direction can separate clean, hazardous and public areas.
- Verify electrical service, panel capacity, grounding, fault protection, emergency power and data infrastructure.
- Map domestic and laboratory water, drainage, backflow protection, floor drains and any treatment requirements.
- Confirm laboratory gases, vacuum, compressed air and specialty utilities, including cylinder storage and distribution.
- Inspect fire detection, suppression, alarms, emergency lighting and egress paths.
Operational and compliance checks
- Assess accessibility, including routes, doors, turning areas, controls and emergency evacuation.
- Plan secure chemical, biological, radioactive and gas storage with inventory control.
- Map sample receiving, material movement, waste staging, decontamination and pickup routes.
- Review access control, intrusion detection, visitor management and after-hours response.
- Obtain a code and zoning review from qualified local professionals because requirements vary by jurisdiction.
NIH’s Design Requirements Manual can serve as a technical reference, but the adopted building and fire codes, permits and university standards govern the project.
Choose renovation or new construction deliberately
An existing building can reduce schedule and embodied construction, but it may hide contamination, constrained shafts, low electrical capacity, poor floor loading or insufficient exhaust. New construction generally offers cleaner separation of flows and easier future expansion, but requires more capital and a longer delivery path. Compare the options against the actual research envelope.
| Decision factor | Renovating the unused building | Building new space |
|---|---|---|
| Code and infrastructure risk | Existing conditions and concealed services can create uncertainty and change orders. | Systems can be designed around the approved hazards and current codes. |
| Schedule | May be faster when the shell and utilities are suitable; abatement or major upgrades can erase that advantage. | Usually requires a longer planning, permitting and construction sequence. |
| Lifecycle flexibility | Columns, floor-to-floor height and existing shafts can limit expansion or reconfiguration. | More opportunity to plan expansion, maintenance zones and separated flows. |
| Legacy-building risk | Requires investigation and possible removal of asbestos, lead, mold or old chemicals. | Starts without those inherited contaminants. |
| Ownership cost | Can be economical when the building has adequate capacity; aging systems may increase maintenance. | Higher initial investment but potentially simpler access and serviceability. |
Make the choice with a risk-adjusted lifecycle estimate, not construction cost alone.
Develop the concept design around flows and maintenance
Create a block plan and room data sheets before detailed drawings. Show people, samples, clean supplies, hazardous materials, waste, emergency responders and maintenance staff as separate flows where the risk assessment requires it.

Plan room relationships
- Place sample receiving and temporary storage near the controlled entry point.
- Keep clean storage away from chemical, biological and waste staging.
- Provide adequate space around hoods, cabinets, freezers and other serviceable equipment.
- Locate hand-washing, eyewash and emergency showers so users can reach them quickly without crossing hazards.
- Provide a controlled route for waste and decontamination that does not pass through public or clean areas.
- Reserve access panels, valve locations and equipment clearances for inspection and repair.
Design for safe finishes and housekeeping
Use durable, cleanable, chemically compatible surfaces and seal penetrations. Avoid details that trap spills or make inspection impossible. Coordinate casework, sinks, utility drops, floor drains and equipment bases with the cleaning and decontamination methods defined in the SOPs.
Obtain approvals before construction
Map every approval to a responsible office and a decision date. A typical university path includes:
- Capital-project and finance approval.
- EH&S design review.
- Institutional biosafety committee review where biological materials or recombinant or synthetic nucleic acids require it.
- Radiation-safety committee and licensing review where radioactive materials or radiation-producing equipment are involved.
- Accessibility review.
- Building, fire, zoning and environmental permits from the applicable authorities.
- Hazardous-material storage and waste-management approvals.
- Occupational-health, security and emergency-management coordination.
Some regulated facilities require design review and final inspection before occupancy. Treat those inspections as schedule milestones, not paperwork to complete after construction.
Renovate infrastructure and install engineering controls
Prioritize controls that protect people even when a user makes a mistake. The risk assessment should determine the number, type and location of controls.
Ventilation and containment
Provide the exhaust, makeup air and pressure relationships needed for the processes. Fume hoods and biosafety cabinets are not interchangeable: a fume hood protects the user from chemical vapors, while a biosafety cabinet is selected for biological containment and may have different installation and certification requirements. Commission airflow, alarms and room pressure rather than relying on nameplate specifications.

Electrical, fire and emergency systems
Install adequate distribution, grounding, emergency power and dedicated circuits for critical instruments. Coordinate fire detection, suppression, emergency lighting and egress with the building and fire authorities. OSHA laboratory guidance addresses lockout/tagout, electrical hazards, fire-prevention planning and special requirements associated with flammable gases.
Water, waste and decontamination
Provide sinks, drainage, backflow protection and any treatment required by the protocols. Define segregation, labeling, storage, pickup and decontamination for chemical, biological, radioactive, sharps and ordinary waste. A waste process is incomplete until a trained person can explain what happens from the point of generation to final disposal.

Storage and security
Use compatible cabinets and restraints for chemicals and gas cylinders. Control access to hazardous materials, specimens, radioactive sources, high-value instruments and sensitive data. Include inventory ownership, after-hours response and lost-key or access-revocation procedures.
Specify, procure and install equipment
Write a requirements specification before requesting quotations. It should state the intended protocol, performance criteria and acceptance tests, not merely a preferred model.
- Utility voltage, phase, amperage, gases, water, drainage, exhaust and data.
- Heat output, noise, floor loading, vibration sensitivity and anchorage.
- Footprint, service clearances, delivery route and maintenance access.
- Calibration, software, cybersecurity, data retention and network ownership.
- Warranty, preventive maintenance, spare parts, response time and training.
- Decontamination method and compatibility with the laboratory’s chemicals and materials.
Coordinate delivery with construction completion and commissioning. Storing sensitive instruments in an unfinished, dusty or unconditioned building can invalidate warranties and create contamination or damage.
Biological equipment requirements
For biological work, plan access to an autoclave when the risk assessment and institutional procedures require it. Illinois laboratory setup guidance calls for access to an autoclave for BSL-2 waste and recertification of biosafety cabinets after relocation. Certification should also be repeated after repairs or other events specified by the applicable standard or university program.
Commission the facility before occupancy
Commissioning is the evidence that the installed laboratory performs as designed. Keep a signed record for each test, deficiency and corrective action.
- Verify installation: Confirm equipment identity, location, anchorage, utility connections, labels, guards and service clearances.
- Test critical utilities: Check electrical circuits, grounding, emergency power, water, drainage, gases, HVAC, pressure relationships, alarms and exhaust.
- Certify containment devices: Obtain applicable fume-hood and biosafety-cabinet certification, including recertification after relocation where required.
- Check emergency equipment: Inspect eyewashes, safety showers, spill kits, fire extinguishers, alarms, emergency lighting and communication systems.
- Validate waste and response: Demonstrate segregation, labeling, storage, pickup, spill response, decontamination and exposure reporting.
- Approve documents: Complete the chemical hygiene plan, biosafety procedures, exposure-control plans, equipment SOPs, emergency contacts and maintenance schedules.
- Train all affected people: Train researchers, students, supervisors, cleaners, security staff and maintenance workers on the hazards and their roles.
- Close deficiencies: Track every defect to an owner and due date; do not accept “temporary” controls without documented risk approval.
- Authorize occupancy: Obtain the university’s final inspection and any required authority approval before research begins.
Occupancy authorization should identify the approved rooms, activities, containment or hazard limits, responsible supervisors and conditions that trigger reassessment.

Maintain a change-control process
Require review before adding a new organism, chemical, instrument, process, user group or operating schedule. Reassess when ventilation, room layout, staffing, equipment or waste routes change. This prevents a small laboratory from drifting beyond the assumptions used to approve it.
Keep a recurring inspection calendar
- Routine user checks of hoods, cabinets, emergency equipment, storage and housekeeping.
- Scheduled certification, calibration, preventive maintenance and alarm testing.
- Inventory reconciliation for chemicals, biological materials, radioactive sources and gases.
- Refresher training and competency checks.
- Periodic emergency drills, incident review and corrective-action tracking.
- Review of utility performance, energy use, service contracts and future capacity.
Funding: what a grant may and may not cover
NIH modernization programs can support renovation and fixed infrastructure when appropriations and program criteria permit. The NIH Grants Policy Statement defines modernization as “alteration, renovation, remodeling, improvement, expansion or repair of, or completion of shell space in an existing building … necessary to make the building suitable for use for the purposes of a particular program.” Eligibility, allowable costs and timing depend on the specific notice and appropriation.
Do not assume a modernization award will pay for routine research operations. Budget separately for staff, utilities, consumables, PPE, waste, calibration, service contracts, inspections and replacement equipment. Confirm allowability with the university’s sponsored-projects and finance offices before committing funds.
Shared core space or dedicated rooms?
Small programs often reduce cost by sharing expensive instruments and support rooms, but sharing changes access, scheduling and contamination controls.
| Factor | Shared core space | Dedicated rooms |
|---|---|---|
| Utilization | Can increase use of expensive instruments across groups. | May leave equipment underused if demand is intermittent. |
| Access and scheduling | Requires booking rules, user authorization and conflict resolution. | Gives the owning group predictable access. |
| Cross-contamination | Needs stronger segregation, cleaning and sample-flow controls. | Can isolate incompatible work more readily. |
| Capital cost | May reduce duplication of instruments and support utilities. | May require duplicate equipment and services. |
| Staffing | Benefits from shared technical support and standardized training. | Places more responsibility on each research group. |
Choose shared or dedicated rooms only after comparing utilization, hazard compatibility, access control, contamination risk, staffing and future demand.
Common failure modes and fixes
Buying instruments before surveying utilities
Symptom: The selected instrument cannot be powered, cooled, exhausted or moved into the room. Fix: Require a signed utility and delivery review against the building survey before purchase.
Treating the BMBL as a permit
Symptom: The team cites a biosafety level but has not assessed the actual protocol or local requirements. Fix: Use protocol-driven risk assessment, then route the design through the university and authorities that have jurisdiction.
