Tunnel scheme brings road improvements

Major road improvements will be made in Huug Hom to give a smooth traffic flow and easy access for vehicles using the Kowloon end of the HK cross-harbour tunnel when it opens in 1972.

The work includes a series of elevated loop roads, pedestrian subways and footpaths and a vehicular bridge over the railway tracks to the proposed terminal at Hung Hom and is timed to be completed well ahead of the tunnel. Part of Chatham Road will be realigned and Princess Margaret Road will be widened from Gascoigne Road to Wylie Road.

The network of roads will allow traffic flow in three directions - westward towards Tsim Sha Tsui by Austin Road and to Yau Ma Tei by Gascoigne Road, northward by Princess Margaret Road and eastward by Chatham Road. Pedestrians are taken

care of by a series of connected footpaths and strategically placed subways from Wuhu Street leading to the HK Technical College.

Another link in Kowloon's new road network, the Chatham Road flyover, was opened last month. The 1,000 ft. long structure, which took less than 16 months to complete, joins Chatham Road with Princess Margaret Road by means of a four-lane carriageway supported on piled foundations across Gascoigne Road.

Slip roads incorporated into the project provide for the traffic flow between Tsim Sha Tsui and Hung Hom, Kai Tak and the northern part of Kowloon.

London research to aid HK tunnel

Laboratory tests carried out at King's College, London, are said to have broken new ground in concrete research. The information obtained will benefit British engineers involved in constructing the Hong Kong cross-harbour tunnel.

The tests were called for as there was no known previous research work on the behaviour pattern of

concrete beams of circular cross-section. Circular piles are to be used for a bored pile retaining wall at the tunnel's northern approach.

Those involved in the research programme were the College's Civil Engineering Department, the joint consulting engineers, Scott Wilson Kirkpa- trick & Partners and Freeman, Fox & Partners, and the main contractors, Costain International Ltd.

Costain commissioned Dr. J.M. Illston, a senior lecturer in civil engineering at King's College to devise and carry out the tests, and to report on a number of important aspects of the behaviour of the beams under shear loading. Dr. Illston was joined in his studies by Mr. A.J. Bushell of Scott Wilson Kirkpatrick & Partners and Mr. K.J. Prang- nell, Costain's chief design engineer.

Work began recently on the Hong Kong tunnel which will contain two 6.7 m (22 ft.) carriageways and will be built by the immersed tube method. Completion is expected in three years.

RP construction groups form joint committee

An "Inter-Organizations Conference Commit- tee', called Intercon, has been formed by the Philippine Institute of Architects, Philippine Asso- ciation of Civil Engineers, Association of Structural Engineers of the Philippines, the Society of En- gineers and the Philippine Contractors Association.

Since its recent inception it has already pro- duced the final draft of a proposed amendment to an article of the Civil Code pertaining to the collapse of buildings. The amendment redefines explicitly the responsibilities of architect, designing engineer, contractor and full-time inspector on the construction of buildings. It also proposes to reduce from 15 to 5 years the period of liability of the professionals concerned.

Intercon is at present reviewing the documents of the different associations that concern the functions of the 'works engineer' or the profes- sionals with full-time superintendence of construc- tion. The aim is to establish a common definition of the responsibilities of the project superintendent to avoid conflicting interests in the professions.

The committee is also checking the conditions and practices of foreign professionals who 'might be encroaching on the works of the local practi- tioner'.

HK's Expo interiors ready

The interiors for the Hong Kong Pavilion at Expo 70 will be shipped to Japan this month. They include 250 display units, fitted with pictures, slides, charts and graphs, all relating to life in Hong Kong. The units were made by two local firms, T.K. Shen Construction Co. and the Hong Kong Industrial (Woodwork) Co. Ltd.

Three sections within the pavilion, dealing with social progress, industrial progress and cultural heritage, have been designed respectively by Jack- son Wong of Wong, Ng Ouyang & Associates,
