Use of several prefabrication techniques with concrete, steel and mixte structures
Structural Solution Optimized for easy and regular transportation
Global Solution for ALL site area
Site Complete in 3 DAYS versus 3 Weeks of best Traditional method
Business Concept LECS Low Energy Consumption Shelter Solution in Study
In not urban regions, the “sites” has to be installed in places of the difficult access (mountains usually). Huge difficulties come in obtain electric power for Transmission and Cooling Equipment
Preventive and Corrective Maintenance of “sites” is done with the teams displacement almost because of basic alarms like the high temperature of BTS, without knowing correctly the main reason of the failures.
Put Solar Passive Solutions, like big thermal inertia, night cooling, earth cooling, évapotranspiration cooling, shadow, etc to arrive to a LOWER need of cooling
Electric supply with an Hybrid Solution of Photovoltaic panels, Fuel Cells and Wind Generators
Technical Management of ALL equipments with Remote Control to avoid unnecessary displacements
Business Concept LPT Light Poststressed Tower Solution in Study
Main problem in high towers is the rotation and deflection (twist and tilt) in the top, because of winds forces in the telecommunication antennas. To avoid this, the towers needs to have a increase of resistance and steel against natural steel elastic deformation.
The use of high resistance steel cables poststressed, inside of the steel profiles of the tower, reduce the the weight of steel , and the price.
Our FDS Solution can be adapted to bigger Wind loads, bigger Antennas or others needs like Electric Generators, etc.
Our Engineering Department can customize a new standard for a client
PROCONSULTORES Fast Deployment Site Solution is patented with number PCT/PT05/000002 . The solution was developed because of the Customers growing needs in quick sites implementation. Our FDS solution was developed for: Towers up to 60m height Wind Speed and Antenna load - Basic wind speed is 120 km/h - Survival wind speed is 160 km/h All Towers were designed to the specified wind speed, limiting the deflection to 0.5° degrees (tilt and twist) under the basic wind speed (the deflection degree is illustrated) It was considered the wind load on Tower members, ladder, platforms, feeders, in addition to the following antenna loads with 10 m2 area at the top: - 06 GSM Antennas - 05 MW dishes Ø 1,20m - 12 Cables 7/8 on the Cable routing along the Tower
FDS – Fast Deployment Site Prefab Concrete Site Fence For hostile zones
SOLUTIONS COMPARISON Fast Deployment Site Traditional Green Field 3 days of Construction in Site (Antennas, Cables, Tower and civil works) => Invoice calls sooner, Earning more Money, Win Costumers from others Operators 3 to 4 weeks for Out => Loose calls, loose costumers to others competitors, Loose Money Without foundations, No Digging needed => No extra cost, No extra time Site construction Foundation necessary, Digging necessary Concrete Foundation subject to underground level and steel bars corrosion. => Extra Cost, Extra Delay Concrete Base with high Corrosion Resistance, don’t subject to underground and surface water level All materials are prefabricated in the workshop, better Quality Control Control => Long Term Less Problems, Less Money for Maintenance Metal Fondations subject to surface water and corrosion All materials are fabricated in Site, more difficult quality control => Greater Risk of Resistance complying, More Maintenance, More Cost Fixed Cost Control => Better Financial Control Variable Cost Control=> Worst Financial Control Easy to dismantle and relocate => Easy to Recycle Foundations and Towers, Environmental Friendly, Save Money in Network Optimisation Impossible to remove and/or relocate Upgrade de height of the tower impossible, new foundation needed => Concrete Recycling Impossible, Waste Money,
Stock possible for a quick start
Better Response in unscheduled Business
Need More Cash Flow
Stock impossible => Slow Response in unscheduled Business => Less Cash Flow Needed The Concrete Base covers all the site with the minimum surface needed, 5mx7,2m, with only one step high of 0,2m from the ground => Cost Optimisation The Foundation don’t cover all the site surface, base slab needed = > More Expensive Towers upgrade from 25m up to 50m with same base Every tubes and infrastructures already included in the base => Less Expensive Every tubes and infrastructures have to be putted in a base slab = > More Expensive Works on low bearing pressure ground (less than 0,1Mpa) => Less Expensive A low bearing pressure ground needs a big and heavy foundation => More Expensive
Resource Requirements Material Concrete Prefabricated Pieces Hot Dip Galvanized Lattice Steel Tower Shelter (Optional) Personnel Civil Works - 3 days x 6 man / site Tower – 2 to 5 days x 3 man / site Electrical – 2 to 3 days x 2 man / site Technology FDS – Fast Deployment Site Solution Certification Logistic Stock surface Transport manager.
• Steel Tower Suppliers without delivery capacity for such tower amount in a short term period

Hybrid system incorporating a photovoltaic array and a diesel generator Hybrid Systems overview
The main feature of a hybrid system is the use of two or more different energy sources. For so called photovoltaic hybrid systems in the field of solar energy especially a diesel generator, a wind generator or a public grid can be used as an additional source of energy. The charge controller designed for hybrid systems manage the charge and discharge of the battery, and protect the loads from over voltage and low voltage as well.
A battery charger supplied trough the generator, charges the battery during night or when the power from the PV array is not enough because of low solar irradiation.
A electric generator working around 85% - 90% of its maximum capacity is desirable because it increases its efficiency and life as well. The true sine wave inverter assures that the AC loads gets power always according to the requirements of the system.
The advantage of photovoltaic hybrid systems is that the solar generator does not have to be oversized to supply the loads even during months with low solar irradiation. This saves a significant amount of the initial investment.
The solar produced power is always used primarily in the system. But in combination with the second energy source reliable AC and DC power is available day and night throughout the year. In systems that are already installed in the field (ex. Telecom sites in remote locations) and where the primary source of power is a fuel generator, a solution with PV modules could be a good one in order to low the costs regarding the maintenance and fuel cost of the fuel generator.
