SINGAPORE - Singapore's construction sector faces increasing risks of a protracted slowdown in growth in the medium term due to the poorer global economic outlook over the next few years, Fitch Solutions Macro Research said in a report on Monday.

The sector will see growth weakening to 2.7 per cent in 2020 and 0.5 per cent in 2021 in real terms, Fitch said.

However, in the short term, the sector is likely to grow by 3 per cent, supported by an expected short-term stronger performance in the building sector.

The research firm on Monday adjusted its short-term growth outlook for the construction sector, up from its previous 2.8 per cent forecast for 2019, after it had also made upward revisions of its forecasts for the residential and non-residential building sector in Singapore.

The building sector accounts for some 70 per cent of the total value of the construction industry, Fitch said. On July 10, the company said the building sector will grow at 3.2 per cent this year and 2.3 per cent in 2020.

"Despite the implementation of property cooling measures in H2 2018, the private residential property index hit a five-year high in Q2 2019, suggesting that it will take a long time for effects of the cooling measures to fully kick in," Fitch said in its report.

Along with the uptick in the supply of buildings observed in 2018, Fitch expects stronger growth in the building sector in the near term, which will lift the construction sector as a whole.

Another factor boosting the short-term growth of the construction sector is the construction of Singapore's largest road project, the North-South Corridor, which is set to start by the end of the year.

In the medium term, the construction industry is expected to face external headwinds from the likely slowdown in growth of the global economy, Fitch noted.

The elevated risks of a global recession over the coming quarters and the uncertainty in markets will dampen demand for residential, commercial, industrial and retail space, resulting in a slowdown in the building sector, Fitch said on Monday.

Over the next decade, average annual growth of the construction industry is expected to be at 2.8 per cent through 2028.

However, a steady pipeline of transport mega-projects will contribute to the recovery of the sector in the long term, Fitch noted.

Compared to the transport sector, the energy and utilities sector will see fewer opportunities, "given the country's already well-developed stock of existing power infrastructure", it added.

There are currently 75 transport projects in the pipeline here, compared to only 19 for the energy and utilities sector, according to Fitch's Infrastructure Key Projects Database.

Over the next decade, the infrastructure sector - in particular, the transport sector - will act as a cushion to the cyclical slowdown in the building sector, Fitch said.

This is supported by Singapore's large pipeline of projects, with mega-projects such as Changi Airport Terminal 5 and the North-South Corridor Expressway starting construction over the next few years.

More recently, the Land Transport Master Plan 2040 was released by the Land Transport Authority, reaffirming the Government's plans to expand the rail network from the current 229km to more than 360km by 2040 with the planned construction of new lines such as the Jurong Region Line and the Cross-Island Line.

Also, in line with Singapore's car-lite vision, the authorities plan to expand the current network of cycling paths from 440km to more than 1,000km over the next decade.

"We expect contracts for these initiatives to be progressively rolled out, providing opportunities in civil engineering and boosting the domestic construction industry," Fitch said.
