BASIC MATERIAL PROTECTION PLAN

APRIL , 2025 pg. 1

I – General

The Plan is established as a baseline document for protection of property and valuable assets in the performance of repairs or projects in Government Owned (GO) properties in Mission France.

All construction areas and pathways in and out of the area should be photo documented prior to any works if not already available.

During invasive works or when a reasonable prospect of damage to property is present as determined by the Facility Manager the following applicable protections are required to be implemented either by FAC staff or contractors.

The listed protections can used alone or in combination as necessary and are required for access pathways as well as project locations.

All protections shall comply with all applicable USA, French and European building regulations and safety guidance below.

A. The safety requirements of the EM-385-1-1 http://www.publications.usace.army.mil/Portals/76/Publications/EngineerManuals/ EM_385-1-1.pdf;

B. The safety requirements within the Occupational Safety and Health Standards https://www.osha.gov/pls/oshaweb/owastand.display_standard_group?p_toc_level =1&p_part_number=1910;

C. Local French occupational safety and health requirement laws and regulations;

D. When there is a difference with the minimum requirements the more stringent requirement shall be followed.

II – Floor and stairwell protections (Interior)

All flooring regardless of material type is subject to damage depending upon work impact to the area.

- As a minimum rosin paper or self adhesive covering and canvas cloth should cover the entire area impacted or be mobilized segment by segment to cover work areas in larger rooms. If not auto adhesive, this must be secured with double side tape or spring tension bars where applicable such as stairs.

Adhesive covering for floors and stairwells

Heavy Plywood protection for floors

Railing protection

- Commercial products such as rolled padding or prefabricated flooring protection products can be used in place of onsite fabricated elements as determined by the COR and budget.

- In cases of heavy traffic or a significant possibility of dropping heavy materials or tools from a height the minimum requirement is canvas cloth as a base styrofoam and 1 cm thick plywood applied over the flat subject area. Plywood thickness should be increased if the type of flooring is unstable. Note: This also applies to any area where mobile (rolling) scaffolding will be used

- If stairwells or atrium areas are to be used for hoisting or debris removal all protections must be increased or doubled and plywood applied to effected areas of any railings to provide both abrasion and structural protection.

- Railings can be covered with plastic, canvas or other textile;

however, the material must be secured with tape or zip ties at no more than 30cm intervals to maintain a safe handhold

APRIL, 2025 pg. 3

III – Scaffolding

Only US or EU approved aluminum or steel scaffolding is allowed for projects administered by the USG. Wood, Bamboo, PVC or other materials are not allowed as part of any project administer by us.

- Rolling scaffolding must be inspected to ensure wheel locks and all connections are secure and stable to operate. Any personnel on the scaffolding must have a US or EU approved safety harness and a hard hat if working on objects above their head.

- Stationary scaffolding of a height more than 2 meters must be equipped with outriggers for stability. All penetrations for mounting must be approved in advance by the COR and the FM along with detailed actions to restore the penetration points upon completion. Anchors used must be suitable to the materials and approved in advance.

All scaffolding connection points will have plastic bolt covers as required for public safety!

Scaffolding visibility barriers if required must meet city standards and affixed to withstand a minimum of 25 Km winds without tearing or flapping.

IV – Phase II – Fixed wall objects and walls

Fixed wall objects can consist of lighting, imbedded plaques, textile/wood wall coverings or decorative architectural elements such as niches.

- Lighting should be removed if possible, but if not then depending upon exposer as a minimum the lighting should be covered with acid free tissue or dartex nylon film and then padded with bubblewrap. Light switches should be labeled in the off position or power cut to the units to prevent overheating.

- Large protections for textile wall coverings or decorative wood panels must be made to ensure air flow is available, but no dust can enter the protection. A wood framework of small 2cm x 2 cm timbers providing a space between the plastic protection and the item as a minimum 2 cm gap.

Plastic 7 mil sheeting will be applied over the frame leaving the bottom and one side (opposite any doors/windows or HVAC units) open. An air permeable fabric will be applied to cover the bottom and open side to allow air flow, but not allow dust from any forced air movement.

Plastic protection for interior decors

- Items that are exposed to only painting functions require only plastic protection, however provisions must be made to ensure that the item(s) are not damaged in the process. Tapes or adhesives used to apply the plastic protection must not damage the item

V – Fireplaces

Decorative fireplaces or mantles can be protected in the same manner as the wall protection (see section III) with one added element.

- Mantles tops and base surrounds require internal plastic sheeting and a minimum of 1 cm plywood placed on the flat surface to protect it from falling objects that could penetrate the plastic protection.

APRIL, 2025 pg. 5

VI – Protection in place of multiple items

When multiple items are placed in a room, the room must first be inspected to decide if any protection is required for the storage. An example would be placing protection over the entire room floor to protect it from the movement, weight or any possible damage from the objects put in place.

- A minimum of furniture protection blankets and 7 mil plastic sheeting should cover all items as a simple precaution and to help in maintaining cleanliness when the entire room will be closed off during the project.

- Gilded surfaces should also be drapped to protect from dust producing activities.

- Environmentally sensitive objects should be separated and protected with a controlled temp/humidity application. CH can provide the necessary requirements in terms of humidity % rates required for the objects.

- Either FAC HVAC specialist or contractors can supply the necessary equipment for the application.

VII –Doorways and room sealing

When it’s determined the best protection, method is to seal rooms from outside activities, then special equipment and procedures need to be followed.

- As a minimum plastic common market available construction “Plastic seal Doorways” must be applied over existing doors or to create clean pathways in and out of construction zones. In some cases, plastic sheeting or small wood frames will be required to support or cover areas not sealed by the prefabricated door seals.

- These plastic doorways may have zipper, Velcro or magnetic slit openings depending upon products available.

- Most are applied with adhesive tape of minimal invasive screws to the surrounding soft surfaces. Mounting points or procedures will be decided by the COR and FM.

- If heavy dust is anticipated as part of the project, then small fans can be placed in rooms of clean spaces blowing in the direction of the opening to create a positive pressure in the clean zones, thus preventing dust from entering.

VIII –Protection for interior/exterior combinations

Projects that involve both interior and exterior evolutions such as doorways, windows and small balconies, then both areas need to be addressed.

In cases where the portal into the bldg. has to remain open to the environment during work hours of the project then adequate protection and/or security must be factored in.

- As a minimum a wood surround screen frame constructed of 5cm x 10cm timbers with 1 cm plywood (security may require more stringent construction). 10 mil plastic sheeting should cover the screen and all other exposed entry points to create a weather protected working “Bubble” area.

- The threshold and interior area determined must have the minimum floor protection (see section II).

IX – Protection of exterior elements

Exterior elements include driveways, facades, vestibules, canopies, railings and stairways.

- Driveways must be evaluated for possible damage depending upon the nature of the project. If heavy equipment is required, then actions to protect from cavitation or collapse of ground must be taken. This may be a minimum of 2cm thick plywood or even steel plate over the track area depending upon the size and weight of the equipment traversing the space.

- Lawns or natural ground spaces need to be determined if protection or support is required or if it would better to restore the area after movement.

- Railings and stairways are common points of access and usually require temporary protections unless it’s included in a façade repair/restoration project.

- Common practice would be to cover exterior stairs with canvas of other heavy fabric textile to prevent slipping unless a commercial product is available. This includes stairs covered with carpet or matting.

- Railings can be covered with the same textile; however, the fabric must be secured with tape or zip ties at no more than 30cm intervals to maintain a safe handhold

- Facades, and other exterior extrusions will require commercial applications by professional contractors to erect scaffolding or build wooden protective structures over extrusions. These applications are normally requested as part of the SOW and Contractors submittals. our job is to ensure they are adequate to the need.

X – Protection of Pathways

Protection in a combination of listed above elements must be employed to protect the pathway from the designated entry point to the construction zone and back out.

This includes any methods of ascension/descension such as stairs, elevators, debris shoots or external lifts.
