Question:
BR Piling Pte Ltd was contracted to install bored piles and construct a basement carpark for a 13-storey building in Singapore. The piling contractor completed the works and handed the site to the architect by the stipulated deadline. The architect was engaged by the owner and was responsible for the design and supervision of works for the entire project. Two weeks later, the project's superstructure work was awarded to another contractor, KC Contractors at a lump sum price of $25 million using the SIA Lump Sum contract (9th Edition). The contract duration is 12 months commencing from 1st Jan 2020. 1a) During the site handover, KC Contractors found out that the basement slab level constructed by BR Piling was 100mm lower than what was required in the approved construction drawings. KC Contractors then informed the architect that topping up with concrete to the required basement slab level was necessary and submitted a quotation of $100,000 for the additional work. KC Contractors also refused to take over the site until the variation cost was approved. The architect called for a site investigation. The result showed that it was an error caused by BR Piling Pte Ltd's land surveyor. Discuss the options available to the architect including the implications. (15 marks) 1b) During the tender period, KC Contractors decided not to purchase a specific type of glass for the project's cladding work because there was no place to store the material and it would not be needed until months later after construction had progressed. The contract specified a particular brand for the glass that had to be purchased from a manufacturer in Belgium. The contract also specified that the contractor was entitled to propose alternative types of glass but they must be of equivalent quality. When KC
Contractors made the glass order from the Belgium manufacturer, the price had risen by 30 percent compared to the tender price.
Discuss the courses actions available to the architect and KC Contractors including the implications.
1c) Prior to the project's complete date, the architect granted an extension of time (EOT) of ten days to KC Contractors but they failed to complete the works by the extended completion date. On 12 January 2021, the architect gave a written order to require KC Contractors to do additional works and granted a further EOT from 12th to 15th January 2021. However, KC Contractors only managed to complete all the Works (including additional works) on 20th January 2021. State the relevant dates and types of certificates the architect has to issue from the contract completion date to the end of maintenance period including the implications of each certificate. (Assume delay certificate is issued one day after the contract completion date) Calculate the liquidated damages due to the owner if the liquidated damages rate is $2,000 per day (inclusive of Saturdays, Sundays and public holidays).
