DETAILED TECHNICAL SPECIFICATION FOR 16M HIGH MAST LIGHTING SYSTEM

HIGHMAST - TECHNICAL SPECIFICATION:

The bidder will have to produce detailed design of High Mast Lighting system with foundation

and manufacturer's quality systems confirming to ISO 18001 for carrying out the job along with

the bid document.

1. Structure of High Mast Tower - 16M(2 sections)

The high mast shall be continuously tapered polygonal section, 20 sided, presenting a

good and pleasant appearance and shall comply with all statutory regulation and safety

codes standards having single longitudinal weld and hot dip galvanized both internally

& externally with single dip process to an uniform thickness of 86 microns. The

structure shall be suitable for wind loading as per IS specification.

2. Construction

The mast shall be fabricated from steel plate conforming to BSEN 10025/IS 5986, cut

and folded to form polygonal section as stated above and shall be telescopically jointed.

The weld shall be in accordance with IS 7318 & IS 817 & the 16 M mast shall be supplied

in two equal sections & each section shall be fabricated out of individual plates duly

folded and welded. There shall be only one longitudinal seam weld per section. Sections

fabricated out of multiple plates or with more than one weld shall not be accepted. At

site the sections shall be joined together by slip-stressed fit method. No welding at site

or bolted joint shall be allowed on the mast. The minimum over lap distance shall be 1.5

times the diameter at penetration. The wall thickness of each section shall be designed

to withstand the load, to which the mast will be subjected to, but shall not be less than

4mm for base and 3.0 mm for the top section. The base diameter and the top

diameter shall not be less than 350 mm and 150 mm respectively. The mast shall be

provided with fully penetrated flange, which shall be free from any lamination or

incursion. The welded connection of the base flange shall be fully developed to the

strength of the entire section. The base flange shall be provided with supplementary

gussets between the bolt holes to ensure elimination of helical stress concentration. The

entire fabricated mast shall be hot dip galvanized, internally and externally, having

thickness of 86 microns and in accordance with IS 2629. The galvanizing have to be

done by single dipping method only for better adhesion and life. The entire structure

should be designed for a minimum life of 25 years.

3. Door Opening :

An adequate door opening shall be provided at the base of the mast and the opening

shall be such that it permits clear access to equipment like winches, cables, plug and

socket, etc. and also facilitate easy removal of the winch. The door opening shall be

complete with a close fitting, vandal resistant, weatherproof door, provided with a

heavy-duty double internal lock with special paddle key. The door opening shall be

carefully designed and reinforced with welded steel section, so that the mast section at

the base shall be unaffected and undue buckling of the cut portion is prevented. Size of

door opening shall not be more than 1000 × 300 mm to avoid buckling of the mast

section under heavy wind conditions.

4. Metering Kiosk:

The Metering Kiosk (2.5ft ×2ft×1.5ft) for power supply will be fabricated by M.S. Sheet

(14 SWG) both side opening door with middle portion separator by wooden partition

including brick foundation & net cementing with S/F of 63A TPN main switch (Havells

Cat. No. IHSRTE4063 or Similar) and interconnection etc.

5. Dynamic Loading for the Mast:

The mast structure shall be suitable to sustain an assumed maximum reaction arising

from a wind speed as per IS 875 (three second gust), and shall be measured at a height

of 10 metres above ground level.

6. Lantern Carriage:

with no chances of rope slippage. The rope termination in the winch shall be such that

distortion or twisting is eliminated and at least 5 to 6 turns of rope remains on the drum

even when the lantern carriage is fully lowered and rested on the rest pads. It should be

possible to operate the winch manually by a suitable handle and by an integral power

tool. Operation of the winch with manual handle shall be independent of the power tool.

Winches with manual operation through the power tool shaft shall not be accepted.

Individual drum operation of the winch shall be possible. A double drum winch shall

the same material. The overall diameter of the rope shall not be less than 6 mm. The

breaking load of each rope shall not be less than 2350kg. giving a factor of safety of over

5 for the system at full load. The end constructions of ropes to the winch drum shall be

fitted with talurit.

The thimbles shall be secured on ropes by compression splices. Two continuous lengths

of stainless steel wire ropes shall be used in the system and no intermediate joints are

acceptable in view of the required safety. No intermediate joints/terminations, either

bolted or else, shall be provided on the wire ropes between winch and Compensating

Disc and Three continuous S/S wire rope will be used for Compensating Disc to lantern

carriage for proper and uniform balancing.
