Penetrations Sample Clauses
The Penetrations clause defines the rules and responsibilities regarding any openings or intrusions made through building elements, such as walls, floors, or ceilings, typically for the passage of pipes, cables, or ducts. It usually specifies who is responsible for creating, sealing, and fireproofing these penetrations, and may require that all work complies with relevant building codes and standards. This clause ensures that penetrations do not compromise the structural integrity, fire resistance, or safety of the building, thereby addressing potential risks associated with unauthorized or improperly executed openings.

Penetrations. The quantity of sleeves shall be one 4-inch (diameter) sleeve per every 100,000 square feet of useable floor space served by the backbone cabling system, plus two spare sleeves for a minimum of three sleeves. Sleeves through the floor shall be adjacent to the door and should not obstruct wall terminating space. Sleeves shall be properly fire-stopped per the applicable codes. Two each 4” riser/conduit sleeves between each TC/IDF and the TR/MDF are required. Sleeves or openings through the telecommunication room floor should be adjacent to the door. LESSOR: GOVERNMENT: Provide a minimum of two dedicated 15-amp, 110 V AC duplex electrical outlets, on separate circuits. Other duplex outlets may be placed at six-foot intervals around the perimeter walls, at a height in compliance with National Electrical Code (NEC) or local codes. The outlets should be connected to an emergency power source if available. No electrical panels or circuit breakers may be installed inside the IDF(s); panel boards serving the IDF shall have TVSS protection. When there is more than one telecommunications closet on a floor, consideration should be given to interconnecting the closets with a minimum of one 3-inch conduit or equivalent. Consideration should be given to the proximity of the closets to the TR/MDF, the number of closets involved, and the telecommunication system to be installed. The bonding and grounding requirements of ANSI/TIA/EIA-607 shall be followed. Refer to grounding requirements in the Electrical section under the MDF Telecommunications Room.
Penetrations. Penetrations" means the square footage of the areas within (and measured from the mid-point of the walls enclosing) the Building stairs, fire towers, elevator shafts, flues, vents, stacks, pipe shafts, vertical ducts and other vertical penetrations. Areas for the specific use of Tenant and installed at the request of Tenant such as special stairs or elevators are not included within the definition of Penetrations and, such areas will be included in the relevant Useable Area.
Penetrations. All floor penetrations shall be caulked, cemented, or filled (immediately upon coring or discovery) with materials that are fire rated and match specifications of the original floor composition. NO PENETRATIONS OR OTHER STRUCTURAL MODIFICATIONS SHALL BE PERMITTED WITHOUT THE APPROVAL OF THE BUILDING STRUCTURAL ENGINEER. DO NOT DRILL OR PENETRATE BUILDING STRUCTURAL BEAMS FOR HANGING OF MECHANICAL EQUIPMENT, PIPING, DUCTWORK OR ANY OTHER EQUIPMENT WITHOUT SUBMITTING FOR APPROVAL. THIS IS A POST TENSIONED STRUCTURE AND MOST BEAMS AND CERTAIN JOISTS ARE POST TENSIONED. DAMAGE TO THE TENDONS WILL BE THE RESPONSIBILITY OF THE TENANT CONTRACTOR IF APPROVALS ARE NOT OBTAINED. APPROVALS MUST BE IN WRITTEN FORM, EMAILS AND OTHER WRITTEN METHODS ARE MANDATORY. All penetrations of piping, duct work, conduits, etc. through wall partitions, and doors shall be fire sealed to the Landlord’s satisfaction, in order to maintain the integrity of the structures fire safety rating.
Penetrations. Locate holes in advance where they are proposed in the structural sections such as ribs or beams. Obtain the approval of the Resident Engineer prior to drilling through structural sections. Electrical Work installed between different environments shall be sealed to prevent moisture or contaminants from traveling from one area to another.
Penetrations. A. Refer to specification 26 05 00 “Common Work Results for Electrical” for requirements related to penetrations, sleeves, sleeve seals and firestopping.
Penetrations. Provide two each 4" straight-through riser conduits from the LEC demarcation point to the TR/MDF room. If this conduit has more than two 90 degree turns, pull boxes are required. If pull boxes are required, they must be 48" long, 6" wide and 6" deep. One of these two riser conduits will require a 6"x6"x48" trough box accessible for cable pulling where it passes through any other floor’s telephone closet. A minimum of two additional 4" conduits are required to be stubbed out to each IDF. Additional 4” conduits may be provided for growth, based on local IRS Telecommunication’s direction and Project Manager approval.
Penetrations. 1. Do not penetrate or otherwise notch or cut structural members, including footings and grade beams, without approval of Structural Engineer.
2. Make penetrations perpendicular to surfaces unless otherwise indicated.
3. Seal interior of conduits entering the building from underground at first accessible point to prevent entry of moisture and gases.
4. Where conduits penetrate waterproof membrane, seal as required to maintain integrity of membrane.
5. Make penetrations for roof-mounted equipment within associated equipment openings and curbs where possible to minimize roofing system penetrations. Where penetrations are necessary, seal as indicated or as required to preserve integrity of roofing system and maintain roof warranty.
6. Install firestopping to preserve fire resistance rating of partitions and other elements.
Penetrations. Subcontractor is responsible for the work related to any and all penetrations through walls, floors, and ceilings, including fire-rated assemblies, associated with the Work.
Penetrations. Sleeves for penetrations through beams, columns, walls, foundations and slabs shall be furnished and installed by Subcontractor so as not to delay or impede the work of others. Subcontractor is responsible for adequately securing such sleeves and verifying correct location immediately prior to, during and after concrete placement. Locations shall be coordinated by Contractor and approved by the Structural Engineer. Subcontractor shall provide files necessary for Contractor to combine all subcontractors’ penetrations on one set of plans. Openings requiring concrete formwork, metal deck cutting or edging will be provided by and, if shown on the architectural or structural drawings, paid for by others. Subcontractor shall identify the locations, quantities and sizes of all such openings. Any additional penetrations through or modifications to structural steel members beyond what is shown on the structural drawings will be provided by others, subject to the approval of the Structural Engineer and paid for by Subcontractor. Subcontractor must identify the locations, quantities and sizes of such penetrations on its shop drawings. Penetrations and modifications required in the field for Subcontractor’s convenience or due to coordination issues with other trades to be provided by others will be paid for by Subcontractor. Subcontractor shall provide field layout of all penetrations required through walls by the scheduled start date for wall framing in the related area if the penetrating sleeve, duct, pipe, etc. is not already installed. Subcontractor shall provide any concrete coring required for its work. Locations and method are to be submitted for approval to Contractor and the Structural Engineer. All penetrations through building elements must be located and dimensioned on Subcontractor’s shop drawings prepared specifically for that purpose by Subcontractor. These drawings must be submitted to Contractor as required by the progress of the Work. Subcontractor is responsible for patching any penetrations made for its Work. Such patching shall return the penetrated item to its original structural, fire resistant, sound attenuation and air pressurization capacity. Penetration patching method and locations must be approved in advanced by Contractor. Subcontractor shall grout, pack or otherwise suitably prepare its penetrations to receive scheduled waterproofing or roofing. Subcontractor shall also provide any counter flashing, roof jacks, stainless steel draw bands...
Penetrations. A. Cutting or Holes:
1. Locate holes in advance where they are proposed in the structural sections such as ribs or beams. Obtain the approval of the Owner prior to drilling, cutting or coring through structural sections.
2. Cut holes through concrete and masonry in new and existing structures with a diamond core drill or concrete saw. Pneumatic hammer, impact electric, hand or manual hammer type drills are not allowed, except where permitted by the Owner required by limited working space.
B. Fire Stop: Where conduits, wireways, and other electronic safety and security raceways pass through fire partitions, fire walls, smoke partitions, or floors, install a fire stop that provides an effective barrier against the spread of fire, smoke and gases with rock wool fiber or silicone foam sealant only. Completely fill and seal clearances between raceways and openings with the fire stop material.
