SAES-T-744Design Criteria and Installation of Communication Towers
SAES-T-744 is a standard that establishes the mandatory requirements for the design and installation of steel communication towers, both self-supporting and guyed. The scope of this standard includes various types of antenna towers used for HF (High Frequency), VHF/UHF (Very High Frequency/Ultra High Frequency), microwave, FM/TV broadcasting, and CATV (Cable Television). However, it is important to note that this standard is not applicable to aluminum towers.
The standard provides guidelines and specifications for the design, construction, and installation of steel communication towers. It ensures that the towers are designed to meet the necessary structural requirements, considering factors such as load capacity, wind resistance, and stability. Compliance with this standard helps ensure the safety, reliability, and performance of communication towers in accordance with Saudi Aramco’s regulations.
Industry Codes and Standards for SAES-T-744
The industry code and standard applicable to SAES-T-744 is the TIA/EIA-222-G, which stands for “Structural Standards for Steel Antenna Towers and Antenna Supporting Structures” published by the Electronic Industries Association (EIA).
TIA/EIA-222-G provides comprehensive guidelines and specifications for the structural design, analysis, fabrication, and installation of steel antenna towers and supporting structures. It covers a wide range of communication tower applications, including HF, VHF/UHF, microwave, FM/TV broadcasting, and CATV.
The standard addresses various aspects of tower design, such as loading criteria, structural analysis methods, member design, foundation design, erection procedures, and maintenance considerations. It aims to ensure the safety, stability, and reliability of steel communication towers in compliance with industry standards.
SAES-T-744 references and adopts the TIA/EIA-222-G standard as the authoritative source for the design and installation of steel communication towers within the context of Saudi Aramco’s guidelines and requirements. Adhering to this industry standard helps ensure that communication towers meet the necessary structural integrity and safety criteria.
Design Criteria and Installation of Communication Towers
In accordance with SAES-T-744, the following additional requirements or exceptions are specified for the design of communication towers:
5.1: All aspects of material selection, detailing, shop fabrication, galvanizing, marking for erection, delivery, erection, and assembly of steel structures for communication towers must comply with 12-SAMSS-007.
5.2: Painting and protective coatings for steel structures of the towers should comply with SAES-H-001 and SAES-H-101.
5.3: Communications towers should not incorporate hollow tubular steel members as part of their structure.
5.4: Ice loading should not be considered in the tower loading calculations.
5.5: The County Listing of Minimum Basic Speeds in Section 16 of TIA/EIA-222-G is not applicable. The design basic wind speed for the tower’s location should be determined based on SAES-A-112 and EIA/TIA-222-G. If data is unavailable for a specific location, contact the Environmental Engineering Division. The operational wind speed requirement for tower structures in Saudi Arabia is set at 60 miles per hour.
5.6: The loading capacity of the tower should be calculated to account for the known loading at commissioning and any additional loading expected within one year after commissioning.
5.7: Foundations and concrete used for the tower should comply with 09-SAMSS-097, SAES-Q-001, and SAES-Q-005.
5.8: To prevent corrosion, all anchor rods should be coated with fusion-bonded epoxy. The coating thickness should be 500 to 625 micrometers (20 to 25 mils) as a dry film.
5.9: Guyed towers should not be installed on offshore structures.
5.10: All guyed tower masts for communication sites require separate SSD/1 or SSD/2 security fencing for each guy, unless already included in the perimeter security fence for the tower. Refer to SAES-O-102 for further details.
These additions or exceptions to the TIA/EIA-222-G standard ensure that communication towers in Saudi Arabia meet the specific requirements and considerations of Saudi Aramco.
