19. 关于新大楼构成部分，秘书长在报告(A/76/330)中指出，由于 COVID-19 大流行，在为设计咨询公司招标时出现了一些进度上的延误，于 2021 年 8 月授予合同。新秘书处大楼的设计将继续保持模块化和可伸缩性，以便在出现任何无法预见的与大流行疫情有关的情况时，这些方面可以在设计开发过程中得到解决(同上，第 19-21 和 43 段)。行预咨委会询问后获悉，根据 2010 年新办公设施项目的既有经验，新大楼的设计将是模块化的，可能包括 2 至 3 个办公区，将对这些办公区进行定制和(或)复制，以达到所需的 10 500 平方米的总面积。报告附件一的表中项目费用计划细列项目 1.3 下所列新大楼构成部分的估计数 18 080 300美元是根据建造大约 11 600 平方米的未来办公空间计算的。根据报告第 9(c)段，2021 年确认的未来办公空间面积为 10 500 平方米，因此，最初的成本估计被认为足以成功交付该项目。行预咨委会还获悉，项目费用计划还为细列项目 3 和 4下的成本上涨和应急拨备提供了经费。
19. In terms of the new building component, the Secretary-General, in his report (A/76/330), indicates some schedule slippages during the solicitation of the design consultancy firm due to the COVID-19 pandemic, with the awarding of the contract in August 2021. The design for the new Secretariat building will continue to be modular and scalable so that, if any unforeseen circumstance related to the pandemic arises, such aspects could be addressed during the design development (ibid., paras. 19–21 and 43). Upon enquiry, the Advisory Committee was informed that, on the basis of prior experience with the new office facilities project in 2010, the new building design would be modular and likely comprise two to three blocks that would be customized and/or replicated to achieve the required gross area of 10,500 m2 . The estimate of $18,080,300 for the new building component shown under line item 1.3 of the project cost plan of the table in annex I to the report is based on constructing approximately 11,600 m2 of future office space. In accordance with paragraph 9 (c) of the report, the confirmed area in 2021 of future office space is 10,500 m2 and, therefore, the original cost estimate is deemed sufficient to successfully deliver the project. The Committee was also informed that the project cost plan also provided provisions for both an escalation and contingency provision under line items 3 and 4.
