RM572,947.23 based on the professional opinion of a Quantity Surveyor who produced a report and testified to what constituted reasonable Reinstatement Costs. [9] At the hearing of the appeal, counsel for the parties submitted that there were no disputes as to the items of repair to which the 3 sets of costs referred (“List of Defects”). The large disparity in the costs put forward were in relation to the same List of Defects. [10] The Plaintiff relied on the quote of RM120,350.00 given by its contractor following a second joint inspection on 13-5-2020 (the first was on 31-3-2020 and the Plaintiff had at the time, estimated the costs at RM90,230.00). [11] The Defendant relied on evidence of a Schedule of Costs and proof of payments made to the Defendant’s contractor for actual work carried out and the professional opinion of the Quantity Surveyor who was offered as an expert and who testified at the trial as SD2. [12] The Plaintiff challenged the completeness of the Defendant’s records of claims and payments for the work done, but the same argument would apply to a greater extent in evaluating the probative value of a mere quotation relied on by the Plaintiff (Chong Nge Wei & Ors v Kemajuan Masteron Sdn Bhd [2022] 4 CLJ 833). [13] The Plaintiff also challenged SD2’s evidence as an expert opinion because his report was not tendered by way of an affidavit pursuant to Order 40A Rule 3 of the Rules of Court 2012. However, failure to tender a written expert opinion according to the requirements of Order 40A Rule 3 of the Rules of Court 2012 does not render it inadmissible or diminish the opinion expressed (Gee Eng Wah v Teoh Eng Keong & Anor [2019] MLJU 495). [14] SD2 testified at the trial of his 30 years’ experience as a Quantity Surveyor and gave his opinion on the estimated Reinstatement Costs for the same List of Defects in a report which was admitted into evidence. The material he reviewed included the joint inspection report, photographs, drawings and site inspections and measurements. This evidence was largely unchallenged at the trial. [15] Based on the relative cogency of the available evidence, this Court found that the balance of probabilities clearly leaned in favour of a finding that the Reinstatement Costs was more reasonably estimated at RM515,212.00 as contended by the Defendant. There was no good reason to disregard the evidence of SD2 whose skill and expertise is precisely to provide the desktop estimates called for in this case. It was closer to and therefore better corroborated the sums incurred by the Defendant. Conclusion [16] For the reasons set out above, this Court allowed the Defendant’s appeal and set aside the Judgment of the Sessions Court with costs here and below in the sum of RM15,000.00. Consequently, the Plaintiff’s claim was dismissed and the Defendant’s counterclaim was allowed.
