General Requirements for Conduit System Design

The general requirements outlined in the provided information are as follows:

4.1 OSP Design Reference:

• TIA-758-A and BICSI Outside Plant Design Reference Manual are recognized as the detailed design references.
• Design drawings should use conventional symbols specified in SAES-T-018 and BICSI.

4.2 OSP Designer Certification Requirements:

• Non-Saudi Aramco design offices must have a valid/current BICSI RCDD and/or OSP Specialty certification.
• External design contractors must have an RCDD and/or OSP specialist who is a direct employee of the company.
• Design drawings must be stamped by the RCDD and/or OSP specialist before issuance for construction.

4.3 Design Lifecycle:

• Conduit systems should be designed to remain usable for 75 to 100 years and meet design requirements.

4.4 Conduit Route Design Considerations:

• Comprehensive design/construction drawings should include facility locations, conduit alignments, size and configuration of MHs, duct length, conduit formation, and depth requirements.
• Existing substructures and other facilities should be identified.
• Special construction details for railroad crossings, bridges, and pipeline structures should be included.

4.5 Number of Conduits:

• The number of conduits depends on the installed service, expected growth, and maintenance requirements.
• Approval from Saudi Aramco, Communications Engineering Department of IT, is required.
• The number of conduits should be specified in the Project Proposal and construction Work Orders.

4.6 Main and Lateral Conduits:

• The total number of main and lateral conduits should account for immediate requirements, expected growth, other requirements, and reserve one conduit for maintenance and repair purposes.

4.7 Conduit Plugs and Seals:

• Conduits between structures should be sealed to prevent intrusion of liquids and gases.
• Watertight/gastight plugs or seals should be placed in conduits entering buildings to prevent the entrance of gas, water, and moisture.

These requirements ensure the proper design, certification, lifecycle, route considerations, conduit numbers, and sealing of conduits for telecommunications outside plant (OSP) systems.

Here are the additional requirements related to safety, security, and specific installation considerations:

4.8 Temporary Conduit Plugs:

• Temporary plugs should be placed in each installed conduit when conduit installation is stopped for any period of time.
• Conduit plug materials should comply with 18-SAMSS-493 or equivalent.

4.9 Safety and Security:

• All Saudi Aramco Safety and Security Requirements and Policies must be observed, including references to GI-0002.100, SAES-T-603, SAES-T-628, SAES-B-Series, SSD’s, and the Construction Safety Manual.
• The Saudi Aramco Safety Policy (Loss Prevention Policy Statement) is presented in GI-0005.002.

4.9.1 Test Atmosphere in Deep Excavations:

• The atmosphere in excavations 1.2 meters (4 ft) deep or more should be tested before permitting anyone to enter.
• Testing applies to excavations in oil production areas, near gasoline/fuel stations, areas with hazardous materials, landfill areas, and intersections with stop signs or signals.

4.9.2 Safety Requirements for Excavations:

• Excavation work should be under the immediate supervision of someone with the authority to modify shoring or work methods to maintain safe conditions.
• Safety guidelines from the Saudi Aramco Construction Manual, SAES-A-114, Saudi Aramco Safety Management guide, and other applicable safety practices should be followed.

4.9.3 Trench Shoring and Sloping:

• Trenches or excavations 1.2 meters (4 ft) or deeper should be safeguarded by shoring or sloping the trench walls.

4.9.4 Excavations Adjacent to Buildings:

• Excavations adjacent to building foundations or footings should not be deeper than the bottom of the foundation or footing whenever possible.
• If excavations need to be deeper, they should not cross an imaginary line extending from the bottom outside edge of the foundation or footing at a 30-degree angle.

4.9.5 Installations in Refineries:

• When designing or installing telecommunication facilities in refinery areas, the Refinery Instruction Manual should be reviewed, particularly chapters related to work permits, excavations, and pile driving.

4.9.6 Installations in Plant Areas:

• When designing or installing telecommunication facilities in plant areas, such as NGL Plants, GOSP’s, Refineries, Bulk Plants, etc., close contact and coordination with the responsible personnel of these organizations should be maintained.
• Review the Operations Instruction Manual, especially chapters related to excavations and control of MH entry in Abqaiq Plants.

These requirements ensure the implementation of safety measures, compliance with excavation guidelines, and coordination with specific areas such as refineries and plant facilities during the design and installation of telecommunication facilities.

4.10 Designing to Avoid Future Problems:

• Conduit pathway designs should consider vulnerability to future disturbance and the degree of mechanical protection required to safeguard the conduit and its contents.
• Feasible avoidance of problem areas such as man-made troubles in the vicinity, unstable soil conditions, road rebuilds or relocations, and unusual heavy traffic loading or the possibility of future heavy traffic loading.

4.11 Special Construction Situations:

• Detailed construction methods must be provided for the following situations:
  a) Crossings of bridges, culverts, etc.
  b) Crossings requiring specially designed structures for attachment.
  c) Crossings under railroad tracks or embankments using boring, jacking, or tunneling methods (refer to SAES-T-906).
  d) Conduits laid through unstable ground requiring piling or other means of support.

4.12 Construction Drawings:

• Construction drawings must include all necessary information for completing the work as designed.
• Information to be provided includes conduit size, type, and location; designation of vacant or occupied conduits; identification of work orders to clear occupied conduits; length of required cable; determination of additional cable needed in pull-through MHs; identification of existing cables that may interfere with new cable placement and necessary rearrangements; and the number and size of cable hooks required.

4.13 Conduit Construction and Trench Work:

4.13.1 Structural Requirements:

• Telecommunication vaults, MHs, hand holes, and pull boxes must comply with the requirements of SAES-Q-001 “Criteria for Design and Construction of Concrete Structures” with the use of epoxy-coated Fusion Bonded reinforcing steel bar in all geographical locations.

4.13.2 Mortar Requirements:

• Mortar used for brick masonry, MH frame and covers, etc., must comply with SAES-M-100 “Saudi Aramco Building Code,” SAES-Q-001 “Criteria for Design and Construction of Concrete Structures,” and 09-SAMSS-097 “Ready Mixed Portland Cement Concrete.”

4.14 Blasting:

• Blasting requirements for trench or MH excavations must be carried out following Saudi Aramco and Saudi Government procedures and guidelines.

These requirements ensure that designs consider future disturbances, provide specific instructions for special construction situations, include essential information on construction drawings, adhere to structural and mortar requirements, and follow appropriate blasting procedures when necessary.
