IX1000: Construction & Renovation Guidelines

EFFECTIVE DATE: September 2006 REVISED DATE: September 2012 December 2012

1.0 PURPOSE

To prevent construction or renovation related infections in staff, clients and visitors. To provide guidelines to be followed during construction or renovation of health care facilities.

2.0 GUIDELINE

2.1. Pre-Approval Assessment A well-managed multidisciplinary team with appropriate expertise will be established early in the planning stage of construction and renovation projects. The multidisciplinary team shall include:

• Infection prevention and control.

• Administration.

• Project management.

• Environmental services.

• Health care (e.g. medical and nursing staff).

• Design (e.g. architects, engineers).

• Operations and maintenance.

• Construction/renovation personnel.

Assessment of the risks to occupants of the health care facility is necessary before construction or renovations begin. The Planning Department and Engineering or operations and maintenance will keep the Infection Control Service informed regarding the location of all areas of renovation and construction as soon as possible, during the planning stages.

The Infection Control /Construction Form will be used by the Infection Control Practitioner, or designated person, when assessing projects.

2.2. Approval

The Infection Control Service must review all planned projects, especially those falling under the category of Class of Preventative Measure Level III and IV. All construction workers must follow the infection control procedures described in this guideline.


Engineering or operations and maintenance and/or the Planning Department in collaboration with the Infection Control Service will determine the Class of Construction Activity for each project.

Infection Prevention and Control Measures for New Projects

Preventative measures I through IV shall apply to all new construction projects (includes construction on vacant land, facility additions, and space redevelopment)

• Prior to construction the constructor shall present an infection control plan to the multidisciplinary team including selection, design, application, specification, and assembly of construction materials to be used in the project.

• Constructor proposed infection prevention and control measures must encompass the duration of the project and ongoing maintenance and operations.

• The multidisciplinary team shall communicate its policies and procedures to the constructor before construction begins.

• The constructor should designate an individual responsible for infection control to liaise with the multidisciplinary team and monitor and coordinate the infection control procedures. The multidisciplinary team should designate a representative to communicate with the constructor and attend construction meetings as necessary.

• On approval of the infection control plan by the multidisciplinary team, the constructor should coordinate infection control education sessions for all suppliers and subcontractors participating in the project. A copy of the infection control plan shall be provided to all subcontractors and compliance will be imposed in all subcontracts.

•

•

• Infection prevention and control measures shall be constantly monitored and shall be reviewed at every construction and project management meeting.

• If, during construction, events that can present infection risks occur, intervention procedures shall be implemented immediately to resolve the problems.

• Plumbing and HVAC systems shall be supplied, installed, and commissioned in accordance with CAN/CSA-Z317.1, CAN/CSA-Z317.2, and CAN/CSA Z318.0.

Infection Prevention and Control Practitioners will be involved in all discussions involving the Class of Preventative Measure Level III and IV and the ICP will sign off the Infection Control Construction permit.

The Infection Control Practitioner must be given a minimum of 48 hours notice by anyone requesting a permit before the scope of work can be assessed and a permit issued.


2.3. Project Monitoring

An Infection Control Practitioner will be assigned to each level III and IV project and will be the liaison with the relevant clinical areas.

The ICP, after consultation and approval from IHA Project Manager (PM), will have the authority to issue a stop work order at any time during the project if, in their opinion, there are inadequate Infection Control Measures and a risk for the spread of dust particles.

Guidelines for Dust Containment during Construction

Engineering and operations or maintenance staff and/or the Planning Department in collaboration with the Infection Control Service will determine the Class of Construction Activity for each project. Please refer to the guidelines below for dust control measures for the Activity Class of the project. If the level of construction activity changes during the course of the project, please notify Engineering and operations or maintenance, and/or the Planning Department and/or the Infection Control Service before proceeding.


CLASS OF

PREVENTATIVE MEASURE

Level I

Engineering or Operations and Maintenance Staff or Constructors

• Minimize dust during construction operations. • Clean the work area with a HEPA vacuum cleaner if necessary. • Wipe work surfaces with a hospital approved disinfectant after the project is completed. • Immediately replace any ceiling tile or access panel displaced for visual inspection.

Plumbing Activities

• Schedule water interruptions during low activity. • Flush water lines prior to reuse - check for discolored water. • Ensure that gaskets and items made of materials that support the growth of Legionella are not

being used. • Ensure faucet aerators are not installed or used. • Maintain as dry an environment as possible and report any leaks that occur to walls and

substructures.

Environmental Services

• Report discolored water and water leaks to Maintenance and Infection Control.

Medical/Nursing Staff

• Minimize patients' exposure to construction/renovation area. • Ensure that patient care equipment and supplies are protected from dust exposure. After construction

• The multidisciplinary team shall review the preventive measures that were undertaken and assess their effectiveness.

Level II Note: In addition to following preventative measure I the following measures shall be met.


• Seal windows and unused doors. • Seal plumbing penetrations, electrical outlets, and any other sources of potential air leaks in the

construction area. • Seal air vents in the construction area and if possible disable until construction completed • Use drop sheets to control dust. • Place walk off mat outside of entrance of construction area to trap dust from the equipment and

shoes of personnel leaving the area. • Wet mop and /or vacuum (with HEPA filtered vacuum) at end of day as well as when the mat is

visibly soiled. • Walk off mats shall be of sufficient size to ensure that constructors have to place both feet on the

mat at least once on exiting the construction area. • Water mist work surfaces to control dust while cutting (note: caution should be exercised when

such techniques are used on cellulose or fibre based materials that are intended to stay in place following construction work).


• Contain debris in covered containers or cover with a moistened sheet before transporting it for

disposal. • Place supplies and equipment in covered containers during transportation through the healthcare

facility to prevent contamination in other areas. • Remove debris in the evening when patients are in their rooms and visitors have left. If this is not

possible debris should be removed at the end of the work day. • Wipe work surfaces with a hospital approved disinfectant at end of project Plumbing Activities

• Avoid collection tanks and long pipes that allow water to stagnate. • Hyper chlorinate (to a minimum of 50 parts per million) or superheat (to a minimum of 70 degrees

Celsius) stagnant domestic water (especially if Legionella is already present in the domestic water supply). The water lines in the construction area and adjacent patient care areas shall be flushed before reuse; and note: Preventative technologies (e.g. silver-copper ion treatments) may be considered in lieu of the techniques specified above.

• Be aware of the impact of techniques to remove bacterial growth and choose the approach that minimizes the risks associated with such work

Medical/Nursing Staff/Administration

• Identify high-risk patients who may need to be temporarily moved away from the construction zone.

After Construction

• The multidisciplinary team shall a. Review the preventive measures that were undertaken and assess their effectiveness;

and b. Conduct a final inspection to ensure that the ventilation system is functioning properly

in the construction area and adjacent areas. • Infection prevention and control personnel shall ensure that the construction area has been

thoroughly cleaned before building occupants are readmitted to the completed construction area.

• Environmental services and healthcare staff shall a. Ensure that the construction area has been cleaned with a HEPA filter-equipped

vacuum cleaner, a wet mop, or both, as necessary, and that horizontal work surfaces have been wiped with a disinfectant; and

b. Report discolored water and water leaks to the maintenance and infection prevention and control departments.

Level III Note: In addition to following preventative measures I and II the following measures shall be

met.

Minimization of dust generation and dispersal


• Erect an impermeable dust barrier, from the floor to the underside of the deck (including the areas above false ceilings) consisting of two layers of 0.15mm (6 ml) fire-retardant polyethylene (or an equivalent barrier) and gypsum wall board protection approved by the multidisciplinary team. The dust barrier shall remain in place until the project is complete and the area has been cleaned thoroughly and inspected. After construction has been completed, the dust barrier shall be removed to prevent the spread of dust and other debris particles adhering to the barrier;

• Use impermeable vessels constructed to contain contaminants. Such vessels shall have a monolithic (one-piece) exterior shell constructed of a minimum of 0.20 mm (8 ml) fibre-


reinforced, fire-retardant polyethylene. The construction of the vessel shall allow for containment of contaminants within the vessel and have ports through which HEPA-filtered vacuum cleaners or portable construction HEPA-filtered air units can be easily attached to draw the unit under negative pressure;

• Vacuum mechanical and electrical systems and spaces above drop or false ceilings, if necessary; and

• Remove protective clothing before entering patient care areas.

Ventilation Systems


• Disable the ventilation system and seal duct openings in the construction area until the project is completed;

• Maintain negative pressure within the construction area using portable HEPA filter-equipped air filtration units that include pressure gauges and an alarm. Filters shall be monitored and replace if clogged or functioning below the manufacturers specifications;

• Ensure that the air is exhausted directly outside and away from intake vents and filtered through an HEPA filter. In conditions that prohibit exhausting exhaust outside, air may be recirculated in accordance with Clauses 6.6 and 7.2.3.6 (CSAZ317.13-07); and

• Ensure that the ventilation system is functioning properly and cleaned if contaminated by soil or dust after the construction project is complete.

Portable construction HEPA-filtered air units

• Construction area exhaust shall be HEPA filtered. Filters shall be visually inspected by the constructor at least daily, condition documented, and replaced when loaded.

• HEPA filtered air units shall be certified at the beginning of any preventative level III or IV construction activity. Units shall be recertified at least every 12 months and the recertification shall be documented.

• Construction, maintenance, and repair area exhaust air shall not be discharged to areas occupied by Population risk group 3 or 4. Measures related to recirculated air shall require approval from the multidisciplinary team.

• The relative space pressures between areas occupied by Population risk group 3 or 4 shall be continuously monitored.

Impact on the facility HVAC system

• Portable air filtration units may affect a facility’s HVAC system; therefore,

• The main facility system shall be verified for operation in accordance with design during construction work.

• The healthcare facility and constructor shall verify the pressure relationships for critical areas near the construction area.

Construction air handling

• Permanent air handling systems should not be used for exhausting air from construction or renovation work areas. Temporary duct work may be installed for such purposes. However, it shall not connect to the facility’s HVAC system.

• In cases where air cannot be directly exhausted outside(not tying into another system), exhaust air may be piped to the building exhaust system if an engineering analysis has been performed by qualified personnel to ensure that the exhaust air will not be re entrained into the occupied


building and the multidisciplinary team approves piping to the exhaust system.

• Where air cannot be directly exhausted outside or piped through the building exhaust system, it may be recirculated into areas of the building occupied by Risk Group 1 or 2 if multidisciplinary team approval is granted. Construction exhaust air shall not be recirculated into building areas occupied by Risk Group 3 or 4.
