装配式建筑具有节约人工成本、节能减排、低环境污染等优点，目前广泛应用于高层住宅。随着装配式住宅的装配率提升，目前个别高层住宅要求装配率达到91%及以上，此类项目与传统全现浇结构或常见的仅混凝土结构采用装配式设计的项目存在着装配式设计，新增加施工管理难点和成本增加的问题。本文从房地产开发商角度出发基于相关评价标准和山东省青岛市的建设项目实际案例对AAA级高装配率高层混凝土住宅项目在装配式设计实现、施工管理和成本变动情况进行研究，本文主要研究内容包括：1、利用对比分析法，总结现行国家标准和山东省地方标准的《装配式建筑评价标准》的差异；发现山东省地方标准相比国家标准，其指标更加细化、部分要求根据当地情况进行调整，并增加了加分项起到鼓励引导作用。此外基于实际施工案例对两个标准中各装配式评价项目提出对应设计实现方法和设计过程中注意要点。2.以山东省青岛市四个AAA级装配式项目为例，利用对比分析法和案例研究法对比了四个项目装配式设计方案差异点和共同点，并比较了差异点产生原因和优缺点，提出了满足国家标准《装配式建筑评价标准》规定AAA级和山东省地方标准《装配式建筑评价标准》规定的三星级装配式住宅设计方案，方案主要通过大幅度提升主体结构装配率、干式工艺和集成厨卫实现高装配率。3.通过案例研究法对高装配率项目施工管理资料进行研究和通过问卷调查法对高装配率项目管理人员进行调研，总结高装配率高层住宅项目施工管理相较于全现浇或常见的仅混凝土结构采用装配式设计的较低装配率项目增加的常见施工管理风险点，并针对风险点提出相关的施工管控措施。4.基于不同装配率的住宅项目施工造价资料，利用案例研究法和对比分析法，对不同装配率等级的高层住宅主要装配式构件成本进行对比分析，研究发现各装配式构件相比非装配式构件成本增加的幅度不同，最高的预制外围护墙体达到155.2%，最低的干法地暖为5.1%。此外分析了山东省青岛市对装配式建筑奖补政策对开发成本的影响，并从建设单位角度总结了前期、设计、招采和施工四个阶段的成本管理措施。

Prefabricated construction offers advantages such as labor cost savings, energy conservation, emission reductions, and minimal environmental pollution, making it increasingly prevalent in high-rise residential buildings. As the prefabrication ratios in prefabricated residential buildings increases,, certain high-rise residential projects are required have an prefabrication ratios of 91% or higher. However, such projects, compared to cast-in-place projects or projects which only concrete structure is prefabricated, face challenges in design, construction management, and increased costs. This paper focuses on a case study of AAA-grade high prefabrication ratios concrete structure high-rise residential projects in Qingdao, Shandong Province, China, investigating their prefabricated design scheme, construction management, and cost variations from the perspective of a real estate developer. The main research objectives include:1.Using comparative analysis to elucidate discrepancies between prevailing national code and Shandong Province‘s local code concerning "Standard for Assessment of Prefabricated Building". It was found that the Shandong Province‘s local code, compared with the national code, delineate criteria more meticulously. Certain specifications are adjusted based on the local conditions and augmented with bonus-point metrics as a form of encouragement and guidance. Moreover, grounded in actual construction case studies, specific design implementation strategies were also proposed, including essential considerations for each prefabrication ratios evaluation item across both codes.2.Taking four AAA-grade prefabricated projects in Qingdao, Shandong Province, as examples, a comparative analysis was conducted via case study methodologies to discern the disparities and commonalities among the prefabricated design schemes of these projects. Moreover, the causes behind these variances were also elucidated, weighing their respective merits and drawbacks, before proposing prefabricated residential design schemes that align with both the national "Standard for Assessment of Prefabricated Building" for AAA-grade and the three-star benchmark for Shandong Province‘s local "Standard for Assessment of Prefabricated Building". The core of these schemes hinges on significantly enhancing the prefabrication ratios of the primary structure using dry construction techniques and the integration of modular kitchen and bathroom units to materialize high prefabrication ratios.3.Case study methodologies were employed to investigate the construction management data of projects entailing high prefabrication ratios, in addition to a questionnaire survey targeting project management personnel. These were conducted to clarify construction management risk points faced by high prefabrication ratios high-rise residential projects compared to cast-in-place structures or usual projects that utilized only concrete structure with lower prefabrication ratios. Then, based on these findings, the most pertinent construction risk mitigation strategies were put forward accordingly.4.Grounded on construction cost data of residential projects with differing prefabrication ratios, and utilizing case study and comparative analysis methods, cost comparisons were made for principal prefabricated components across different prefabrication ratios tiers of high-rise residences. The findings indicate that the cost augmentations between prefabricated and non-prefabricated components vary, with the precast external envelope witnessing the steepest surge at 155.2%, and the dry method of underfloor heating registering the slightest at 5.1%. Furthermore, the study also probed into the fiscal impact of Qingdao‘s incentive policies for prefabricated constructions on developmental costs, before culminating the investigation by encapsulating cost management strategies during the preliminary, design, procurement, and construction phases from the developer‘s perspective.
