Rules of the Facility for Construction Contractors

VA Sierra Nevada Health Care System is a multi-faceted health care facility tasked with providing health care to the men and women who have served in the armed forces of the United States of

America in order to provide for the defense of this county. At all times while working within the facility grounds all contractor’s employees must follow the below listed rules of the facility and treat all patients who they may come in contact with utmost respect and dignity. Any contractor employee who mistreats a veteran or violates any of the rules listed below will be removed from the facility.

1. All patient information is private and cannot be disclosed to others.

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 4

o If a contractor employee sees a friend, neighbor or other acquaintance receiving health care at the facility they are not to discuss who they saw at the facility with anyone regardless of the circumstances.

o Any information overheard or seen regarding a patient’s medical condition is likewise not to be shared with anyone regardless of the circumstances.

2. Safety is a top priority for the facility.

o Contractor must present evidence that each on-site employee has completed the 10 hour OSHA safety training course and evidence that each supervisor has completed the 30 hour OSHA safety training course for supervisors.

o Contractor employees shall at all times wear proper safety attire for the work being accomplished. Further, all contractor equipment and work areas shall be observed at all times. Unattended ladders, doors to electrical closets or mechanical rooms being left open, access panels or manholes covers being moved and not protected are serious safety violations and could result in the dismissal of the responsible employee and a stand-down for the prime and all subs. The General or Controlling Contractor is responsible for site safety, and the employer is responsible for the performance of the tasks of his/her employees. Note that the extent of the measures that a controlling employer must take to satisfy its duty to exercise reasonable care to prevent and detect violations is less than what is required of an employer with respect to protecting its own employees.

3. Electrical: De-energized Panels and Lockout/Tagout o All contracting firms have sole responsibility for the systems given that they install and maintain. If

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 5

contractors work on energy producing systems that are normally serviced by FMS personnel or need to control the energy to the systems for which they have responsibility, then the lockout/tagout operations will be performed by the contractor and overseen by the primary COTR who validates that the contractors have applied their lockouts/tagouts in the appropriate locations.

o Likewise, work on electrical panels can only occur if the panel is de-energized. Likewise, all utility systems are to be shut-down and certified as being off line prior to the contractor tapping into the system.

4. Infection control is a top priority for the facility. No work will be allowed to occur anywhere within the facility until an

Infection Control Risk Assessment (ICRA) form has been filled out and all required work activities properly required by the completed ICRA have been implemented including, but not limited to construction of dust barriers and installation of

HEPA filters. The hospital side of job access points must be kept pristine; use of sticky mats and continual sweeping/mopping and other appropriate measures to keep facility areas clean are to be provided by the contractor as needed

5. Contractor employee parking. No contractor is permitted to park on hospital property with either their personal or business vehicle – use the streets. Contractor’s employees vehicles found parking on campus are subject to being ticketed

(with fine) by VA Police with notification to the CEO of the prime.

6. Contractor discussions regarding project details or related impact are NOT to occur with anyone at the VA without the

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 6

permission or presence of the COTR or other authorized representative from FMS.

7. Contractor employee use of facility toilets and restrooms.

Unless otherwise specified in the contract drawings and/or specifications no contractor employees are to use facility toilets or restrooms.

8. Facility work hours. The facility is an operating health care center and as such activities occur on a 24-7 basis. However the majority or services provided by the facility occur between the hours of 7a and 5p, Monday through Friday. The contractor is to schedule all work activities as necessary to minimize the impact of the construction activities on the day-to-day operations of the facility. Unless otherwise arranged, contractor work hours are limited to 7:30a to 4p.

9. Utility shutdown. No utility shutdowns will be allowed without proper prior coordination with the medical center.

Minor utility shutdowns (those which in no way impact patient care activities) are to be scheduled no less than 72 hours in advance of the planned shutdown. Major utility shutdowns

(those which do impact patient care activities) are to be formally requested no less than 21 days in advance of the requested shutdown.

10. Contractor’s staging area. There is limited space available for the contractor to use as a staging location. Unless otherwise noted in the contract drawings or specifications, all staging of equipment and materials is to occur within the boundaries of the limits of construction as shown on the contract documents. Coordination for street use for dumpsters, storage, pedestrian protection is between the contractor and the City of Reno. Contractor to submit application and ATSSA certified traffic control plan to the

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 7

City of Reno Public Works prior to starting work. Coordinate permit requirements and permit approvals with City of Reno

11. Fire alarm or fire sprinkler work and/or tie-ins. No removal, relocation, disconnection, disabling or connection to the existing facility fire alarm or fire sprinkler systems are to occur until the contractor has obtained the approval of the facility safety manager. It is recommended that wire guards be installed over sprinkler heads within construction boundaries. The contractor is responsible for paying the cost of any fire department response when said the response is due to negligence by the contractor.

12. Hot work. No hot work is to occur until the contractor has received an approved hot work permit from the facility safety manager via the COR.

13. Firearms, knifes, etc. This facility is located on federal property. In accordance with federal law, no person, unless authorized to do so (Federal police and government agents only at this facility) are allowed to carry firearms or knifes on property grounds.

14. Alcohol. This facility is located on federal property.

Therefore, the possession, sale of or use of alcohol on the grounds is strictly prohibited.

15. Smoking. Smoking is not allowed anywhere in the facility inside buildings and only in selected areas outside buildings as defined by marks on the pavement.

16. Fire Egress. As a functioning medical facility it is imperative that, in the event of a disaster which requires evacuation, the evacuation routes are available to patients and staff. Blocking of stairwells, corridors, exit doors and other means of evacuation are strictly prohibited unless

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 8

approved by the Facility Safety Manager as evidenced by his signature on a posted Interim Life Safety Measure (ISLM) document.

17. Handicap Accessibility. As a functioning medical facility it is imperative that all handicap access areas, including ramps, sidewalks, handrails, etc. remain unobstructed at all times unless approved by the Facility Safety Manager as evidenced by his signature on a posted Interim Life Safety Measure (ISLM) document.

18. Debris removal. All debris to be removed from a construction site off site for disposal is to be properly covered whenever it exits a construction area and enters an area occupied by the facility. Tossing of debris materials out of windows or off roof areas without proper use of a trash chute is strictly prohibited.

19. Use of electronic equipment. As a medical facility there is a large amount of electronic equipment that is used by the facility to track patient condition. Handheld electronic equipment such as cell phones, walkie-talkies, radios, Ipods, has the potential to impact the signals provided by the medical equipment thereby impacting patient care. Therefore no handheld electronic equipment is to be used by any contractor employee in the vicinity of areas where health care is provided.

20. Badges. Identification badges are provided for use of all contractor employees. These badges are to be worn by the employee at all times they are on facility grounds. Any contractor employee who is either not wearing or cannot, upon questioning, produce their badge is subject to be removed from the facility. A background check is performed for any employee who will be on-site more than seven days.

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 9

21. Project Submittals on Site. At all times when work is in progress the contractor is to have a set of approved submittals on site for verification that the specified and approved items are being installed. These are to be made available at any time per request of the COR.

22. Confined Space. Several areas within hospital grounds are considered Confined Spaces and some of those require Permit.

You must have submitted and received COR approval of a contractor implemented Confined Space program prior to any access of these areas.

23. Keys. No VA key will be provided to a contractor. Access must either be via VA employee or through a contractor locking system.

1.8 INFECTION PREVENTION MEASURES

A. Implement the requirements of VAMC’s Infection Control Risk

Assessment (ICRA) team. ICRA Group may monitor dust in the vicinity of the construction work and require the Contractor to take corrective action immediately if the safe levels are exceeded.

B. Establish and maintain a dust control program as part of the contractor’s infection preventive measures in accordance with the guidelines provided by ICRA Group as specified here. Prior to start of work, prepare a plan detailing project-specific dust protection measures, including periodic status reports, and submit to COR and Facility ICRA team for review for compliance with contract requirements in accordance with Section 01 33 23, SHOP DRAWINGS, PRODUCT DATA AND SAMPLES.

C. Medical center Infection Control personnel shall monitor for airborne disease (e.g. aspergillosis) as appropriate during construction. A baseline of conditions may be established by the medical center prior to the start of work and periodically during the construction stage to determine impact of construction activities on indoor air quality. In addition:

1. The COR and VAMC Infection Control personnel shall review pressure differential monitoring documentation to verify that pressure differentials in the construction zone and in the patient-care rooms are appropriate for their settings.

The requirement for negative air pressure in the construction zone shall depend on the location and type of activity. Upon notification, the contractor shall implement

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 25

corrective measures to restore proper pressure differentials as needed.

2. In case of any problem, the medical center, along with assistance from the contractor, shall conduct an environmental assessment to find and eliminate the source.

D. In general, following preventive measures shall be adopted during construction to keep down dust and prevent mold.

1. Dampen debris to keep down dust and provide temporary construction partitions in existing structures where directed by COR. Blank off ducts and diffusers to prevent circulation of dust into occupied areas during construction.

2. Do not perform dust producing tasks within occupied areas without the approval of the COR. For construction in any areas that will remain jointly occupied by the medical Center and

Contractor’s workers, the Contractor shall:

a. Provide dust proof two hour fire-rated temporary drywall construction barriers to completely separate construction from the operational areas of the hospital in order to contain dirt debris and dust. Barriers shall be sealed and made presentable on hospital occupied side. Install a self-closing rated door in a metal frame, commensurate with the partition, to allow worker access. Maintain negative air at all times. A fire retardant polystyrene, 6-mil thick or greater plastic barrier meeting local fire codes may be used where dust control is the only hazard, and an agreement is reached with the COR and Medical

Center.

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 26

b. HEPA filtration is required where the exhaust dust may reenter the breathing zone. Contractor shall verify that construction exhaust to exterior is not reintroduced to the medical center through intake vents, or building openings. Install HEPA (High Efficiency Particulate

Accumulator) filter vacuum system rated at 95% capture of

0.3 microns including pollen, mold spores and dust particles. Insure continuous negative air pressures occurring within the work area. HEPA filters should have

ASHRAE 85 or other prefilter to extend the useful life of the HEPA. Provide both primary and secondary filtrations units. Exhaust hoses shall be heavy duty, flexible steel reinforced and exhausted so that dust is not reintroduced to the Medical Center.

c. Adhesive Walk-off/Carpet Walk-off Mats, minimum 600mm x

900mm (24” x 36”), shall be used at all interior transitions from the construction area to occupied

Medical Center area. These mats shall be changed as often as required to maintain clean work areas directly outside construction area at all times.

d. Vacuum and wet mop all transition areas from construction to the occupied medical center at the end of each workday. Vacuum shall utilize HEPA filtration. Maintain surrounding area frequently. Remove debris as they are created. Transport these outside the construction area in containers with tightly fitting lids.

e. The Contractor shall not haul debris through patient-care areas without prior approval of the COR and the Medical

Center. When, approved, debris shall be hauled in enclosed dust proof containers or wrapped in plastic and

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 27

sealed with duct tape. No sharp objects should be allowed to cut through the plastic. Wipe down the exterior of the containers with a damp rag to remove dust. All equipment, tools, material, etc. transported through occupied areas shall be made free from dust and moisture by vacuuming and wipe down.

f. Using a HEPA vacuum, clean inside the barrier and vacuum ceiling tile prior to replacement. Any ceiling access panels opened for investigation beyond sealed areas shall be sealed immediately when unattended.

g. There shall be no standing water during construction.

This includes water in equipment drip pans and open containers within the construction areas. All accidental spills must be cleaned up and dried within 12 hours.

Remove and dispose of porous materials that remain damp for more than 72 hours.

h. At completion, remove construction barriers and ceiling protection carefully, outside of normal work hours.

Vacuum and clean all surfaces free of dust after the removal.

E. Final Cleanup:

1. Upon completion of project, or as work progresses, remove all construction debris from above ceiling, vertical shafts and utility chases that have been part of the construction.

2. Perform HEPA vacuum cleaning of all surfaces in the construction area. This includes walls, ceilings, cabinets, furniture (built-in or free standing), partitions, flooring, etc.

FINAL CONSTRUCTION DOCUMENTS 01 00 00 - 28

3. All new air ducts shall be cleaned prior to final inspection.

1.9 DISPOSAL AND RETENTION

A. Materials and equipment accruing from work removed and from demolition of buildings or structures, or parts thereof, shall be disposed of as follows:

1. Reserved items which are to remain property of the Government are noted on drawings or in specifications as items to be stored. Items that remain property of the Government shall be removed or dislodged from present locations in such a manner as to prevent damage which would be detrimental to re-installation and reuse. Store such items were directed by

COR.

2. Items not reserved shall become property of the Contractor and be removed by Contractor from Medical Center.

3. Items of portable equipment and furnishings located in rooms and spaces in which work is to be done under this contract shall remain the property of the Government.
