The TKM PRE-ENGINEERED RAPID

DEPLOYMENT BTS SITEA Patented Design of TKM Maestro Ltd ®.

The ChallengeRapid Site Build:To create a Rapid Build Site that can be

t t d i h lf th ti St d d Sitconstructed in half the time as a Standard Site.

A Smaller Site:A Smaller Site:To create a Site Design that occupies less than half the Space of a standard BTS Site.

A Recoverable Site:To create a Site that can be recovered and reusedTo create a Site that can be recovered and reused elsewhere after a Period of Service.

The Competitive Edge:To create a Site that offers the Telecom Provider an undisputed Competitive edge in both Economyundisputed Competitive edge in both Economy and Rollout execution.

The Solution

• A Steel All Bolted Pre Engineered Structure.

• Pre Cast Concrete Foundations + SteelFoundation Option.

• Fabrication in controlled FactoryEnvironmentEnvironment.

• Rapid Bolt Only BTS Site Erection.p y

• Modular, Re-usable Site

Lower Site Acquisition Costs (50% smaller Site Area): Smaller Site Area leads directly to q ( ) yless Site Acquisition and Rental Costs.

Rapid 2 week Site Build possible : Site is Designed for a Rapid 17 day Site Build period.

Shorter Towers required (3 meters less): Shorter Towers required for this Site Design due to the 3meter Pre Engineered Site Height.

Excellent Remote Site Solution : The entire Site is transported and simply erected on Site, eliminating all wet Concrete works.

Recoverable Site : The Site can be recovered relocated and reusedRecoverable Site : The Site can be recovered, relocated and reused .

Fewer Cable Trays and Feeder Cables : Shorter Feeder Cable lengths result due to Compact nature of the Site.

Potentially lower Power Costs: Expect savings in Power Consumption due to enhanced cooling.

Less Ducting and Manholes : Only 1 Manhole, less Ducting required as the Cable trays are laid on the Site floor.

3

Co-location is possible : New pre-engineered site can be placed next to the original Site.

Added Security: Enclosed nature of Site reduces Pilferage

Pre Cast Concrete Foundations(Option A)

Th P E i d Sit i• The Pre-Engineered Site issupported and Bolted onto a PreCast Class RC Foundationproviding Overturning Stabilityproviding Overturning Stability.

• The BTS Shelter, Generatorand Tank sit on this Foundationand Tank sit on this Foundation.Equipment provides additionalOverturning Stability.

• Steel Formwork adapted,Concrete poured in Controlled

conditions

•Bearing Pressure exerted onthe Ground at 36 m/s wind

d i 120 KN/ 2speed is 120 KN/m2.

Truss Frame Steel Foundation (Option B)

Pre Engineered Site issupported and Bolted ontoa Truss frame steelfoundation filled with PreCast concrete blocks.

The truss foundation isplaced into a freshlyexcavated and blindedfloor. The base is nowready for immediateready for immediateerection of the mainframe.

Bearing Pressure exertedBearing Pressure exertedby this Design on theGround at 36 m/s windspeed is 120 KN/m2.pMost Soils will have aCapacity above this.
