                            Some of our Engineering projects


                                              Refurbishment of the green screen studio at Metroscreen.

                          On The Mark was contracted to refurbish the ageing Chroma Key studio at Metroscreen.

                     

                                                Destruction begins.                                 Removing 10mm thickness of paint.

                      New storage locker with added storage above.                             New wall frames in place.

                                        New walls up                                                     Grinding concrete floor to remove all old paint

                                           New green screen

                  May 2009 we at On The Mark Film Productions have had the opportunity to assist in the installation of a wind turbine
                  through  CONERGY  for Hornsby City Council in NSW. This was a great privilege to be part of the assembly for
                  this new technology from  PROVEN  ENERGY  based in Scotland.

                       

                                                                                   Installing blade springs

                                

                                                                                   Installing limiting cables

                                                                                                It's up

Once On The Mark Film Productions decided that the company would convert the new facilities to solar power we approached CONERGY for the Solar Panels and Inverter and other supplies needed. On The Mark Engineering designed and manufactured the substructure for the solar panels then with the special mounting rails for the panels also installed the array over the specially built shed. The array was also designed with the ability to have more panels added later without any modifications needed just in case the need for power increases.

The shed serves as a safe and dry storage environment for the batteries as well as the Sunny Island Inverter, and also the generator. It also serves as part of the main support structure for the solar array. It has withstood extremely strong winds and severe rain.   

This conversion was a blessing as now none of our production and post production facilities relies on mains power. In fact we don't even have mains power at all. With using just solar power the electricity is clean and delivers an even voltage with no dropouts or gray outs.

                            

With the use of EXIDE gel batteries as the storage medium there is ample power for all of our needs.

The engineering division includes many aspects of construction. Energy efficiency and low maintenance is in the forefront. Within the construction we have consulted on design and application of many types of building styles and techniques. Some have combinations of log and timber frames and straw bales. On The Mark is currently involved with a combination timber frame/straw bale home.

The combination of the timber frame and straw bale was unique. This time instead of the usual square timbers these were left as only flattened on the wall side and for the headers two sides were flattened to accommodate a flat surface to place the trusses on.

Installing hot water heating in the slab was the owners request to keep even heating throughout the home in winter.

Installation of the piping is very critical.  Securing the pipe directly to the reinforcing mesh gives the best outcome. Run length should not exceed 125 meters. Keeping the runs between 100 and 125 meters means that the amount of water temperature in each run remains close to the same in each run.  Spacing of the runs is also important, the hot or in pipe should start on the outside or the cold part of the building and be spaced closer together. Then as you get into the interior of the building the spacing can increase. This is so the colder outside walls don’t loose the heat too fast. The warmer interior is easier to heat. The Diameter of the pipe is also extremely important. For residential or domestic applications the inside diameter of the pipe should not exceed ½ inch or 11 mm. the reason for this is that, if the diameter is larger the volume of water to be heated is too great and the boiler will be over worked resulting in excessive cost to operate the system. In the colder parts of the world this type of system has been used for it low operating costs for years. This home has Rehau pipe in the slab for in floor heating. This type of heating/cooling system if installed correctly is the most efficient way to keep any building at the desired temperature. Do your research and look world wide and choose what system fits your needs.
