Name of Project: Power Solution for Matsapha Airport in Eswatini.

Description

  • Matsapha Airport is an airport located near Manzini, a city in Manzini District of Swaziland. It serves flights of the Swazi Government and mercy flights. A new International Airport King Mswati 111 was commissioned in 2014.
  • We were contacted by the client to provide a solution for the Matsapha airport as the facility was old and had encountered numerous electrical problems, with no power in certain key areas.
  • We were also requested to provide a solution for backup power for the entire offices including the fuel station. We also had to include uninterrupted power for data center and the radio room which monitors the airlines aircraft worldwide.

Methodology

  • After conducting an assessment our conclusion was that a 200 KVA generator, and two UPS’S had to be installed.
  • We traced and repaired all faulty electrical cables and circuits.
  • We decided to run a cable from the generator directly to the fuel station with a secondary change over board there.
  • Upon further assessment when we were on site more faults were identified, i.e. underground cables under the hanger floor were damaged. This resulted in us rerouting some of the armored feeder cabelling.
  • We realized most of these faults after we had already quoted the client.
  • So, we re-looked at the whole scope of work with all the ads on and decided that we will redesign the solutions within the original same budget that was initially quoted.
  • We came up with a solution to upgrade the incoming supply to the generator, then at the generator install a new feeder DB on the load side, which then ran the existing office wing.
  • We installed a new cable to a new DB located at the center between the existing working DB and the second wing existing DB which did not have power.
  • From the new sub-DB, we then re- routed the light and plug circuit supplying the radio room, this was hard wired into the ups, with its own circuit breakers and earth leakage.
  • The result of this was uninterrupted back up power for the plugs and lights in that room.
  • The data UPS was a plug-in system and was an easy installation.
  • We then re-routed the cable feeding the non-powered DB to the new DB, giving that wing power.
  • We also found another cable which went to a store next to the fuel station which was not powered, we re-routed that cable to the new DB, extended from the store to the DB which fed the fuel station, changing the supply to the fuel station onto the same supply as the building and thus the fuel station is now backed up by the 200 KVA generator as well.
  • We mainly used local labor for tasks like civil work and trenching, we only sent a three-man crew for a week and a further crew to finalize the installation, main connections and commissioning. The majority of the material was purchased in SA and transported to Eswatini.

How we Exceeded Expectation

  • We upgraded the incoming supply from an 80A to a 160A
  • Full integration of the electrical system into one supply and giving a fully working solution.

Name of Project: DStv Delicious International Food and Music Festival

Description

  • DStv Delicious International Food and Music Festival is an annual springtime
    outdoor music attraction that includes gastronomical experience as well. The festival took place in Kyalami Grand Prix Circuit in Midrand
  • GPA ELITE was required to provide a full turn-key solution for the event infrastructure. We had to design, install and manage all logistics within our scope, for the duration of the event.

Deliverables

  • Power for the entire event.
    - Eskom power used, 500 KVA
    - Generators used, 2,4 MVA
    - 6,5 Km x three phase trailing cables various sizes, from 32A to 400A
    - 100 x distribution boards
    - 600 x extension cables (9 Km).
  • Lighting, including lighting in the parking areas for better security.
    - Install 370 x fluorescent lights in the marques
    - 15 x self-powered lighting towers for the parking and general areas.
    - 40 x flood lights for general areas.
    - 6 x LED rope lights for the stairs, walkway.
  • Air-conditioning, for all VIP suites.
    - We installed 96 x 60 000 Btu floor standing units, (total 5,76MBtu in cooling).
  • Gas, ensuring a safe environment for the storage and safe handling.
    - We set up a temporary depot where we stored and managed around 60 x 9Kg gas bottles.
    - Full bottles were separated from the empty ones,
    - The 50 food vendors were also allowed to bring in their own gas, but this had to be stored in our store and managed by our team.
  • Water, where needed, throughout the site.
    - We installed 30 sinks and 40 taps throughout the venue.
    - 4 Km water piping.
    - Safely managed and disposed of the grey water produced at the kitchens when cooking.
    - All the sinks fed into 25L drums which needed to be emptied periodically into a 1000L bowser.
    which was on a trailer, towed away and emptied into the sewerage system.
    Bearing in mind that the entire event was temporary and on tar, everything had to be on top of the ground as we could not dig.

Methodology

Although the client provided us with the layout of the event, the information was minimal. We had to design the event based on assumptions using our past experiences and knowledge gained in doing similar events.

  • Time management was crucial for us, the venue had to be ready the day before the event as various companies had to set up their equipment and be ready for the event.
    - 1st to the 20th September was set up,
    - 21st September the venue had to be ready for people to load in their equipment
    - 22nd to the 23rd the event was live
    - 24th to the 30th was used for the removal of all equipment, the site had to be handed back to Kyalami Race track by the 1st October and everything had to be cleared.

How we Exceeded Expectation

  • During the first week of setting up another event was running at Kyalami (Comicon) and we were also involved with this event providing power and air-conditioning.
  • Because of this event our set up was delayed for Delicious, however we still managed the site and delivered on time.

Name of Project: Nelson Mandela Foundation Centenary Dinner

Description

  • The Centenary Dinner was an event to celebrate Nelson Mandela’s Centenary, post the lecture which was delivered by President Obama earlier in the day at the Wanderers Stadium in Johannesburg.
  • The event was held at Nasrec Expo Centre, South of Johannesburg.
  • GPA ELITE was required to provide a pleasant climate for the VIP guests.

Deliverables

  • Provided air-conditioning, ensure that the event is properly heated and that there is a pleasant climate for the guests.
  • Installed 180 x 60 000 Btu floor standing units, (total 108MBtu in heating).
  • We used 1,6 MVA in generators to power the air-conditioning.

Methodology

  • Used the Air cons as heating.
  • Used larger container units which could not heat purely as ducting to the middle of the venue.
  • Pumped hot air from gas heaters into various bigger units so that the air going in was heated and not trying to heat from single digit.
  • Time management was crucial as the venue had to be heated for the day of the event.
    - We had the 1st to the 16th July to set up,
    - 16th July we had to start heating the venue to be ready for the event on the 17th,
    - 18th to the 21st was used for the removal of all equipment,
    - 22nd July the site was handed back to Nasrec ensuring that it is in the same condition as we found it on the first day of set up

How we Exceeded Expectation

  • This event was held in a 15 000 square meter marquee in the middle of winter. On the night of the event the outside temperature was 5 degrees.
    - We ensured that the average temperature within the 15 000 square meter marquee during the event was above 20 degrees
    - We did not only heat the hall as requested but we also added some infrared heaters in the walk ways to the toilets to minimize the cold.
