Nordbase Structures for Telecommunication Antennae

Introduction ….2 NordBase Engineering ApS has extensive experience in the mobile telecommunications industry to which it provides engineering solutions and consultancy services. NordBase has a large portfolio of structures designed specifically to support antennae. These include lattice towers and masts, monopoles and lamp posts. The NordBase portfolio comprises twenty series. Available in all series are generally a range of heights and structure strength classes. Structure strength classes are provided to suit various wind speed, terrain, and serviceability requirements. Structure designs are based upon BS 8100, Eurocodes 1 and 3 and relevant national documents. Further details are located in the Technical Information sheet contained in this document. The engineering aspects, proven through field experience, and the variety of options for antenna mounting, cable management, antenna access, and foundation design, provide a sound basis from which client requirements can be either directly accommodated or met with easy adaptations. This document contains a brief introduction to NordBase’s structures for telecommunication antennae. It is intended to provide a quick reference for shortlisting structures and associated services that best suit particular needs. NordBase is continuously innovating and improving its technical solutions: as a result, the details in this document may, from time-to-time, change. Further information can be obtained by contacting one of the offices listed on the back page.

Technical Information ….3

• Design Basis

Structure designs are based on BS 8100, Eurocodes 1 and 3, or ANSI/TIA/EIA–222–F, as required.

When a standard or code is not specified, Eurocodes, and the applicable National Application Document (NAD) are used. If necessary, wind information is obtained from meteorological data.

British Standards (Especially for the UK):

BS 8100-1:1986, Lattice towers and masts. Code of practice for loading BS 8100-2:1986, Guide to the background and use of Part 1 'Code of practice for loading' BS 8100-3:1999, Code of practice for strength assessment of members of lattice towers and masts BS 8100-4:1995, Code of practice for loading of guyed masts BS 5950-1:2000, Structural use of steelwork in buildings. Hot rolled sections

Parameters:- BS 8100 Quality Class A structure. Partial safety factor on steel material 1.10, on wind load 1.152 / 1.202, depending on the client. Structure strength classes L, N, S covering reference speeds VB from 24.0m/s to 28.8m/s and terrain categories I to IV according to BS 8100. (VB is the mean hourly wind speed, 50 year return period).

Eurocodes:

Eurocode 1 Part 2-4, ENV 1991-2-4:1995, Basis of Design and Actions on Structures, Wind Actions Eurocode 3 Part 1-1, ENV 1993-1-1:1993, Design of Steel Structures, General Rules Eurocode 3 Part 3-1, ENV 1993-3-1:1997, Design of Steel Structures, Towers and Masts ENV 1090-3 Part 1: 1996, Execution of Steel Structures, General Rules

Parameters:- Normal (Class 2). Partial safety factor on steel material 1.10, on wind load 1.40 For safety, Ultimate Limit State (ULS), based on 50 year return wind period For deflection/rotation, Serviceability Limit State (SLS), based on 10 year return wind period

National Application Documents:

These accompany Eurocodes and are used (a) to verify the equivalent method for calculating the wind loads and the structure load capacity, (b) to take into consideration the specific wind condition and ice load in each area, and (c) to secure the level of safety desired by each country.

• Structural Steel Quality

S235 and S355 – EN 10025 / 10210 / 10219

• Load Capacity

This is the effective area in square metres (m2) allocated to antennae and antennae support poles. The values in this document are provided to give an approximation of load capacity. In final assessment, serviceability requirements and site-specific wind conditions need to be considered.

• Serviceability

The serviceability (deflection/rotation) is the maximum deflection in elevation and azimuth at the top of the structure. For a fully laden NETC structure this is typically 0.3 to 1.0 degree (10 year return wind) and depends upon terrain condition, height, structure type, and strength class (L,N,S).

• Fatigue Service Life

In excess of 25 years.

NordBase has other structures, such as flag and stub poles.

For example, the R00.13000 is a stub pole, 3 to 5 metres in height, with a ring for mounting panel antennae. Load capacity is 5m2. Feeders and microwave cables are routed alongside the access ladder. An optional service platform can be provided. Details of other NordBase structures are available upon request.

NordBase Ancillaries for Telecommunication Structures

• Antennae Mounting Arrangements

NordBase can provide a number of different antennae mounting arrangements to accommodate most requirements. These include face mount, ring mount, space diversity set-ups, single pole and multi-pole mount. Antennae mounting arrangements are specified upon agreement with the client.

• Antenna Access, and Access Safety

All towers, with the exception of the very slim monopoles, where access is by way of a cherry-picker, are supplied with uncaged access ladders as standard items. The fall arrest system, anti-climb protection, rest platforms and ladder cage, are specified upon agreement with the client.

• Lightning Protection and Earth Connection Points

A lightning finial, plates for earth connection - at structure top and bottom (as well as every ~ 20m), and an earth plate on structure foot or feet (i.e., all lattice tower legs) are installed. The earth plate on the foot provides connection to the earth ring.The above are provided as standard items.

• Cable Management

Monopoles are equipped with internal cable suspension systems as standard items. In multi-operator monopoles, each operator’s feeders can be run in their own plastic tube. In large monopoles, external cable routing is offered as an option. Lattice towers generally have the cable management system integrated with the climbing ladder.

• Aircraft Warning Lights

Aircraft warning lights that comply with international civil aviation agreements will be provided whenever specified.

NordBase Ancillaries for Telecommunication Structures

• Foundation Design

A foundation design for normal ground conditions is included with every structure. Depending upon structure size, type and ground conditions, the foundation design of either a raft/block, mono-pile or pier-and-pad type will be supplied. As an alternative, the loads for the independent design of a foundation can be provided.

• Cast-in Parts

Cast-in parts are provided as standard items. Exposed steelwork is hot dip galvanised. Bolts are spun galvanised and supplied with nuts and washers. If required, the cast-in part template can be supplied.

• Corrosion Protection

All tower, mast and monopole steel material, except stainless steel, is hot dip galvanised externally and internally in accordance with EN ISO 1461 or specific client requirements. Circular hollow section tubes remain open for drainage and ventilation.

• Painting

Structures can be painted to satisfy most requirements including those stipulated by international civil aviation agreements. The paint is applied on top of the galvanising. This surface protection system provides superb protection against corrosion.
