NordbaseStructures for Telecommunication Antennae

Introduction.2

NordBase Engineering ApS has extensive experience in the mobiletelecommunications industry to which it provides engineeringsolutions and consultancy services.

NordBase has a large portfolio of structures designed specifically tosupport antennae. These include lattice towers and masts,monopoles and lamp posts.

The NordBase portfolio comprises twenty series. Available in all seriesare 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 andrelevant national documents. Further details are located in theTechnical Information sheet contained in this document.

The engineering aspects, proven through field experience, and thevariety of options for antenna mounting, cable management,antenna access, and foundation design, provide a sound basis fromwhich client requirements can be either directly accommodated ormet with easy adaptations.

This document contains a brief introduction to NordBases structuresfor telecommunication antennae. It is intended to provide a quickreference for shortlisting structures and associated services that bestsuit particular needs.

NordBase is continuously innovating and improving its technicalsolutions: as a result, the details in this document may, from time-to-time, change.

Further information can be obtained by contacting one of the officeslisted on the back page.

Technical Information .3

Design Basis

Structure designs are based on BS 8100, Eurocodes 1 and 3, or ANSI/TIA/EIA222F, as required. When a standard or code is not specified, Eurocodes, and the applicable National ApplicationDocument (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 loadingBS 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 mastsBS 8100-4:1995, Code of practice for loading of guyed mastsBS 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 terraincategories 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 ActionsEurocode 3 Part 1-1, ENV 1993-1-1:1993, Design of Steel Structures, General RulesEurocode 3 Part 3-1, ENV 1993-3-1:1997, Design of Steel Structures, Towers and MastsENV 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 1.40For safety, Ultimate Limit State (ULS), based on 50 year return wind periodFor 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 thewind loads and the structure load capacity, (b) to take into consideration the specific wind conditionand 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 finalassessment, 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 thetop of the structure. For a fully laden NETC structure this is typically 0.3 to 1.0 degree (10 yearreturn wind) and depends upon terrain condition, height, structure type, and strength class (L,N,S).

Fatigue Service Life

In excess of 25 years.

Antennae Mounting Arrangements

NordBase can provide a number of different antennae mountingarrangements to accommodate most requirements. Theseinclude face mount, ring mount, space diversity set-ups, singlepole and multi-pole mount.

Antennae mounting arrangements are specified upon agreementwith the client.

Antenna Access, and Access Safety

All towers, with the exception of the very slim monopoles, whereaccess 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 andladder cage, are specified upon agreement with the client.

Lightning Protection and Earth Connection Points

A lightning finial, plates for earth connection - at structure topand bottom (as well as every ~ 20m), and an earth plate onstructure 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 systemsas standard items. In multi-operator monopoles, each operatorsfeeders 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 systemintegrated with the climbing ladder.

Aircraft Warning Lights

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



12/14

NordBase Ancillaries for Telecommunication Structures

Foundation Design

A foundation design for normal ground conditions is includedwith every structure.Depending upon structure size, type and ground conditions, thefoundation 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 afoundation can be provided.

Cast-in Parts

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

Corrosion Protection

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

Painting

Structures can be painted to satisfy most requirements includingthose stipulated by international civil aviation agreements. Thepaint is applied on top of the galvanising. This surface protectionsystem provides superb protection against corrosion.
