ROYAL GRANDSTAND

Turf Club

Selangor Turf

'HE architects' brief for designing

T the new Royal Grandstand at

Selangor Turf Club was to produce a building with no columns to obstruct the view of the full race track and to provide all the necessary facilities and amenities to serve an ever increasing number of racegoers.

The present design was submitted to. and accepted by. the Selangor Turf Club in late 1964. Construc- tion started in 1965 and was complet- ed early this year in about 15 months. The total cost of erection was M$2.5 million.

For a building of this nature, the structure is an important factor gov- crning its design because while it is desirable to have no columns to ob- struct the view, it is also a fact that the building will be subjected to very heavy live load, the result being that the columns and beams tend to be on the large side.

To give the spectators uninterrupt- ed viewing, the galleries of the Selan- gor grandstand are cantilevered out of the main row of columns.

The second floor gallery has a pro-

jection of 25 ft. from the centre of the supporting columns, with six rows of seatings in tiers. On the third floor the three tiers are cantilevered a dis- tance of 22 ft. while the columns are spaced in a grid of 24 ft. longitudin- ally and 43 ft. laterally.

In Situ Concrete

Main beams supporting the canti- levered galleries are spaced at 12 ft. centres; that is two beams to each 24 ft. bay.

Except for the roof of the specta- tors' stand the structural system em- ployed is reinforced concrete, cast in situ. From the outset. an economic structural system was one of the ma- jor aims.

The roof is of corrugated alumi- nium roofing sheets on steel trusses with the main ones spaced at every 24 ft. Steel trusses are used here be- cause they are more economical and lighter in weight than a concrete roof which brings problems of expansion and water proofing.

The roof measures more than 100

ft. in width, of which about 50 ft. is a cantilevered projection to shelter the spectators in the seating and standing galleries.

The steel trusses were locally manu- factured, and assembled in sections at site. They were fixed in position by means of hoists without the use of any scaffolding, although the highest point of the roof is about 56 ft. above the ground.

The main building, which is the spectators galleries, is three storeys high and is rectangular in shape 264 ft. long and 80 ft. wide. The block in front. containing the en- trances, laboratory, restaurant and kitchen is two storeys high and mea- sures 95 ft. long and 44 ft. wide.

Roofing for this restaurant block is made up of two layers. The inside layer, which is also the ceiling, con- sists of three full shallow barrel vaults in the middle and two half shallow barrel vaults at the two ends. The outside layer is made up of precast concrete slabs, placed to resemble in- verted barrel vaults.

timber grand stand, built 90 years ago. the new stand provides accommoda- tion for more than 4.000 spectators, plus the various administrative offices, a veterinary laboratory, and an air- conditioned restaurant with a fully equipped kitchen. The complex con- sists of two buildings linked appro- ximately in the middle by a lift and stair tower. It is supported by a foun- dation of 374 precast concrete piles.

A factor of considerable import- ance which had to be taken into ac- count in the design of the new grand- stand was the existing race

course

building on the east side, built some 10 years ago. This building had to be kept in its existing form with the new buildings so designed that there was as little disparity as possible.

Thus, the scale of the existing build- ing has been faithfully adhered to. Precast concrete decorative grille blocks have been used extensively in the Jalan Ampang (entrance) eleva- tion to "marry up" the two buildings. The first and second floor levels of both buildings are also maintained so as to provide connecting links be- tween the buildings.

Easy Circulation

However, the planning of the new grandstand has been kept to a simple form the accent being on the easy flow of the various users, namely the officials, members, owners, trainers, jockeys, and public.

The public enters through a cover- ed entrance with ticket counters and accesses to both the existing and the new grandstand. In the foyer of the new building the public is quickly transported to the various floors and galleries by means of two escalators, each capable of carrying about 5,000 persons per hour, a 20-person lift and the usual staircases.

The VIP entrance is situated on the west side of the restaurant block, with its own air-conditioned reception room and foyer, which lead directly to a
