North-South Corridor: Costs of two-year delay to be known only after completion, LTA says

LTA says it will assess whether any additional costs will be borne by the contractor or the agency itself, once the project wraps up.

SINGAPORE: The additional cost arising from the two-year delay to the North-South Corridor project will only be known after the project is completed, the Land Transport Authority (LTA) told CNA on Friday (Sep 18).

LTA will also determine whether any additional costs will be borne by the contractor or the agency itself, a spokesperson said.

“The final additional cost, including the allocation of costs between the parties, could only be ascertained upon the completion of the project,” said the spokesperson.

“As works are still ongoing, LTA is not in a position to comment on project costs at this stage.”

The project was originally expected to cost S$7.47 billion.

The comments come a day after LTA announced the delay, citing unexpectedly challenging ground conditions. The news sparked concerns among nearby businesses over their livelihoods, as well as among residents over the daily inconveniences from prolonged construction.

LTA provides tenderers with available ground information to establish a baseline understanding of site conditions as part of the tender process, the spokesperson said.

“Tenderers are expected to take into account construction risks that shall be taken as an experienced contractor when pricing their tender.

“If the ground condition encountered during construction differs from the baseline information provided, the contractor can submit a claim for assessment.”

LTA will then “make an assessment and consider additional payment” if the claim is deemed valid under contract provisions.

“LTA’s priority remains to ensure that the NSC is completed expediently without compromising safety,” said the spokesperson.

LTA URGES PATIENCE, UNDERSTANDING

Following the announcement on Thursday , businesses near the construction sites told CNA that they were seeing falling earnings, footfall and visibility, with some considering shutting down.

“LTA recognises that the revised timeline means businesses in affected areas will experience the construction impact for a longer period and appreciates their continued patience and understanding,” said the spokesperson.

The impact from construction is expected to progressively ease from next year as more activities move underground, reducing the extent of works at surface level.

Major underground structural works are expected to be completed progressively from 2028, allowing affected areas to be reinstated once they are no longer required for construction, said the spokesperson.

“Ahead of the full opening of the NSC, LTA will continue to return affected areas to public use where safe and practicable,” added the spokesperson.

“Businesses and residents can expect improvements such as the removal of hoardings and temporary noise barriers, reinstatement of roads and footpaths, and restoration of pedestrian facilities and amenities where feasible.”

陆路交通管理局表示，项目结束后，将评估任何额外费用是由承包商还是由该机构本身承担。

新加坡：陆路交通管理局（LTA）周五（9月18日）告诉亚洲新闻台（CNA），南北走廊项目延期两年所造成的额外成本只有在项目完成后才能确定。

发言人表示，陆路交通管理局还将决定任何额外费用是由承包商承担还是由该机构自行承担。

发言人表示：“最终的额外成本，包括各方之间的成本分摊，只有在项目完成后才能确定。”

“由于工程仍在进行中，陆路交通管理局目前不便对项目成本发表评论。”

该项目最初预计耗资74.7亿新元。

就在陆路交通管理局宣布因地面条件出乎意料地复杂而推迟工程的第二天，这些评论便出现了。该消息引发了附近商户对生计的担忧，以及居民对长期施工带来的日常不便的关注。

发言人表示，陆路交通管理局会向投标者提供可用的现场信息，以便他们在投标过程中对场地条件有一个基本的了解。

“投标者在报价时，应考虑经验丰富的承包商应承担的施工风险。

“如果在施工过程中遇到的地质条件与提供的基准信息不同，承包商可以提交索赔申请进行评估。”

如果索赔被认为符合合同条款，LTA 将“进行评估并考虑额外付款”。

发言人表示：“陆路交通管理局的首要任务仍然是确保国家安全委员会尽快完成建设，同时确保安全。”

LTA呼吁保持耐心和理解

周四宣布这一消息后，建筑工地附近的商家告诉 CNA，他们的收入、客流量和可见度都在下降，一些商家甚至考虑关门歇业。

“陆路交通管理局意识到，修订后的时间表意味着受影响地区的商家将面临更长时间的施工影响，并感谢他们持续的耐心和理解，”发言人表示。

预计从明年开始，随着更多活动转移到地下，地面工程规模缩小，施工的影响将逐渐减轻。

发言人表示，主要的地下结构工程预计将从 2028 年开始逐步完成，一旦不再需要用于施工，受影响的区域即可恢复原状。

发言人补充说：“在国家体育中心全面开放之前，陆路交通管理局将继续在安全可行的情况下，逐步将受影响区域恢复为公共用途。”

“企业和居民可以期待一些改善措施，例如拆除围挡和临时隔音屏障，恢复道路和人行道，并在可行的情况下恢复行人设施和便利设施。”
