Supply, install, testing and commissioning of illuminated DTGM (shall have three sides arranged in triangular shape) signage boards in the existing runway both sides are designed to assist pilots to determine the length of the runway remaining during take-off and landing. The power supply from the series circuit through the isolating transformer each sign is equipped with LED Driver Unit completely assembled and connected to LED PCBs inside the board by varying the current of the CCR in the range of 2.8 to 6.6 A the LED Driver provides a constant current to each step. The sign is equipped with two pole cable lead with L-823 Plug complete. Notes: 1) Accessories required for illuminating the sign board such as connectors, cable, isolating transformers are taken separately under relevant items. 2) Contractor should submit the technical specifications and drawings of illuminated DTGM Board along with duly approved from ICGAS. 3) The vertical faces will be 5' x 4' (5 feet height and 4 feet width) in black back ground which should be above the ground. The upper 4' x4' portion of the vertical faces will be used for writing the numeral/ letter with orange paint/orange retro reflective tape. The lower one foot of the vertical portion of vertical faces are not to be used for writing numerals/letters keeping in mind changes of grass/ vegetation growth on runway and taxi way shoulders. The material chosen for the two vertical faces, three support bases and horizontal spurs for third faces should meet the frangibility requirements.

Supply, install, testing of Double sided internally illuminated LED based Mandatory/information/Location/VOR check point Runway/Taxiway guidance signage of various sizes made out of 4mm thick glare free poly carbonate sheet at front and body made out of 2.0mm thick powder coated aluminium profile having minimum width of 1.50mm and supported at back by 50mm and supported at back by 50mm dia, 3mm thickness, die cast aluminium pipe at a separation as required, and frangible coupling as required. Light source shall be high luminous, long life typical 50,000 Hrs. type, 0.5 Watts LEDs assembled on aluminium PCG. The thickness of the aluminium PCG should be 2mm in order to ensure proper heat dissipation. These aluminium PCBs should be placed not more than 160mm apart across the length of the board in order to ensure uniform distribution of light across the board. Each board having length from 800mm up to 3000mm should be illuminated by a single converter & by using single isolation transformer of suitable wattage in order to save the capital cost of multiple isolating transformers. Signage shall be suitable for operation on series circuit at variable current from 2.8 Amp-6.6 Amp and will give constant brightness for all current variation. AlI the signage shall have letters and symbols made by computerized cutting of vinyl and pasting on the polycarbonate sheet from inside/outside of the sign face of required colour as per ICAO complete all as specified and as directed. Note: -contractor should submit the technical specifications and drawings of illuminated double sided guidance signage Boards along with duly approved from ICGAS and signage shall have letters & symbols made by computerised on sheets duly approved from ICGAS before procurement of material
