Sample Grade-2 Constructor Practice Questions

Try these sample questions to test your Grade-2 Constructor exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under the Chinese Construction Project Manager system and the PRC Construction Law, what is the statutory status and primary responsibility of the Construction Project Manager (项目经理)?
A.The Project Manager is the statutory representative (法定代表人) of the construction enterprise and bears unlimited civil liability
B.The Project Manager is the designated representative of the enterprise's legal representative on site and the first person responsible for project construction management
C.The Project Manager is an independent third-party supervisor appointed directly by the government housing bureau
D.The Project Manager is an agent of the project owner (建设单位) responsible solely for financial disbursement approval
Explanation: According to the PRC Construction Law and national construction project management specifications (GB/T 50326), the Construction Project Manager (项目经理) is the authorized representative appointed in writing by the enterprise's legal representative (企业法定代表人) to manage the construction project, and acts as the first person responsible (第一责任人) for project quality, safety, schedule, and cost management.
2Which type of project organizational structure is characterized by a strict single command source (单一指令源) where each subordinate node receives orders from only one direct superior, commonly used in military and conventional construction projects?
A.Functional organizational structure (职能组织结构)
B.Linear organizational structure (线性组织结构)
C.Matrix organizational structure (矩阵组织结构)
D.Work Breakdown Structure (工作分解结构)
Explanation: In a linear organizational structure (线性组织结构), command relationships run strictly vertically along hierarchical lines. Every sub-unit or individual has only one direct superior, eliminating conflicting orders from multiple departments. In contrast, functional structures suffer from multiple command sources, and matrix structures have dual command sources (vertical line and horizontal project).
3According to the national standard 'Code for Construction Organization Plan of Building Engineering' (GB/T 50502), how are Construction Organization Plans (施工组织设计) classified based on their scope and detail level?
A.Preliminary Design, Technical Design, and Working Drawing Design
B.General Construction Organization Plan, Unit Project Construction Organization Plan, and Construction Scheme (施工方案)
C.Feasibility Study Report, Construction Permit Application, and Quality Acceptance Dossier
D.Safety Plan, Environmental Plan, and Quality Assurance Plan
Explanation: GB/T 50502 classifies construction organization plans into three hierarchical levels: (1) General Construction Organization Plan (施工组织总设计) for entire project groups or complex clusters, (2) Unit Project Construction Organization Plan (单位工程施工组织设计) for single standalone buildings or structures, and (3) Construction Scheme / Specialized Plan (施工方案) for critical division/sub-division engineering works or specialized tasks.
4In the dynamic control cycle (动态控制原理) of construction project targets, what is the correct sequence of core managerial steps?
A.Target decomposition -> Target tracking & data collection -> Target comparison -> Deviation analysis -> Corrective action
B.Deviation analysis -> Target decomposition -> Corrective action -> Target tracking -> Acceptance
C.Corrective action -> Target tracking -> Target comparison -> Target decomposition -> Final accounting
D.Target tracking -> Corrective action -> Target decomposition -> Milestone signing -> Post-evaluation
Explanation: The fundamental principle of dynamic control (动态控制) involves: (1) Decomposing project targets and defining planned baseline values (目标分解与计划值确定), (2) Regularly tracking actual progress/cost and collecting actual values (目标跟踪与实际值收集), (3) Comparing planned values with actual values (计划值与实际值比较), (4) Analyzing deviations if any occur (偏差分析), and (5) Implementing corrective organizational, technical, economic, or contractual measures (采取纠偏措施).
5In a double-code network diagram (双代号网络图), what is the function and characteristic of a virtual activity / dummy arrow (虚箭线 / 虚工作)?
A.It represents a critical construction task that consumes significant labor and budget
B.It consumes neither time duration nor physical resources, serving solely for logic linking, distinction, or rupture elimination
C.It represents an activity with negative float that will cause severe project delay
D.It indicates an external milestone deadline imposed by the client
Explanation: In double-code CPM network diagrams, a dummy activity (虚工作) is represented by a dashed arrow. It consumes zero duration (t = 0) and zero resources, and is used exclusively to express logical dependencies between tasks (联系), avoid ambiguous duplicate numbering of parallel tasks sharing start/end nodes (区分), and eliminate false logical relationships (断路).
6A construction network plan has five paths with durations as follows: Path 1: 18 days; Path 2: 24 days; Path 3: 21 days; Path 4: 24 days; Path 5: 16 days. Assuming no external contractual constraints, what is the planned total project duration (计算工期) and what are the critical paths?
A.Duration is 18 days; Path 1 is the critical path
B.Duration is 24 days; both Path 2 and Path 4 are critical paths
C.Duration is 21 days; Path 3 is the only critical path
D.Duration is 103 days (sum of all paths); all paths are critical
Explanation: In CPM network planning, the calculated project duration is equal to the duration of the longest path from the start node to the end node. Here, the maximum path duration is 24 days. Any path that has the maximum total duration is a critical path (关键线路). Since Path 2 and Path 4 both have a duration of 24 days, both are critical paths.
7Activity M in a double-code network schedule has an Early Start (ES) of Day 4, a Duration (D) of 6 days, and a Late Finish (LF) of Day 15. What is the Total Float (总时差 TF) of Activity M?
A.3 days
B.5 days
C.6 days
D.9 days
Explanation: Early Finish (EF) = Early Start (ES) + Duration (D) = 4 + 6 = 10 days. Total Float (TF) is the difference between Late Finish and Early Finish: TF = LF - EF = 15 - 10 = 5 days (or equivalently, Late Start LS = LF - D = 15 - 6 = 9 days, and TF = LS - ES = 9 - 4 = 5 days).
8Activity K has a duration of 5 days and an Early Start (ES) of Day 8. It has two immediate successor activities: Activity P with ES = 16 days, and Activity Q with ES = 14 days. What is the Free Float (自由时差 FF) of Activity K?
A.1 day
B.3 days
C.6 days
D.8 days
Explanation: The Early Finish of Activity K is EF = ES + D = 8 + 5 = 13 days. Free Float (FF) is defined as the minimum Early Start of all immediate successor activities minus the Early Finish of the activity: FF = min(ES_successors) - EF_K = min(16, 14) - 13 = 14 - 13 = 1 day.
9In a single-code network diagram (单代号网络图), what does the circular or rectangular node represent, and what does the arrow represent?
A.Nodes represent milestone events; arrows represent work activities with durations
B.Nodes represent work activities (including name, ID, duration); arrows represent logical dependencies between activities
C.Nodes represent labor teams; arrows represent material delivery routes
D.Nodes represent cash disbursement milestones; arrows represent financial audits
Explanation: In a single-code network diagram (单代号网络图 / Activity-on-Node AON), each node represents a distinct work activity, containing the activity code, name, and duration. Arrows (箭线) represent only the logical precedence relationships (dependencies) between tasks and carry no duration or resource consumption.
10Compared to CPM network schedules, what is the primary advantage and primary limitation of a traditional Gantt chart (横道图) in construction management?
A.Advantage: accurately displays total float; Limitation: difficult to understand for workers
B.Advantage: clear, intuitive, and easy to read; Limitation: cannot clearly show logical dependencies between activities or identify the critical path
C.Advantage: automatically recalculates resource leveling; Limitation: cannot depict calendar dates
D.Advantage: mathematically guarantees lowest cost; Limitation: only applicable to projects under 1 month
Explanation: A Gantt chart (横道图) is simple, intuitive, and clearly depicts start dates, finish dates, and durations against a calendar timeline. However, its major drawbacks are that it cannot clearly represent complex logical dependencies between tasks, cannot calculate total and free float, and cannot explicitly identify the critical path or critical activities.

5Master GB 50300 Acceptance Hierarchy: Know the sequence from Inspection Batch (检验批) -> Sub-item (分项) -> Sub-division (分部) -> Unit Project (单位工程), along with main control item 100% compliance and general item >=80% compliance rules.
6Practice the 28-Day Claim Rule: Learn that the contractor must submit a formal claim intention notice within 28 days of the claim event, follow up with a detailed substantiation report within 28 days thereafter, and the supervising engineer has 28 days to respond.

Frequently Asked Questions

What is the Grade-2 Constructor (二级建造师) qualification and what is its practice scope?

The Grade-2 Constructor (二级建造师) is a statutory professional qualification in China governed by provincial Housing and Urban-Rural Development Departments (省住建厅) and Human Resources and Social Security Departments (省人社厅) under the unified syllabus of MOHURD and MOHRSS. Licensed Grade-2 constructors are legally authorized to serve as Project Managers (项目经理) on small- and medium-scale construction projects within their registered administrative province, lead site construction operations, and stamp official construction management deliverables.

How does the Grade-2 Constructor differ from the Grade-1 Constructor?

Grade-1 Constructors (一级建造师) hold a nationwide qualification that authorizes them to serve as project managers on large, medium, and small construction projects across all provinces in China without geographic restriction. Grade-2 Constructors (二级建造师) are qualified to lead small- and medium-scale projects, and their initial practice registration is primarily effective within the province where the certificate was issued (though inter-provincial mutual recognition is increasingly adopted under national guidelines).

What is the examination structure, passing threshold, and score validity cycle?

The examination comprises three papers: (1) Construction Project Management (建设工程施工管理, 100 pts, 2.0 hrs), (2) Construction Regulations & Related Knowledge (建设工程法规及相关知识, 100 pts, 2.0 hrs), and (3) Professional Engineering Management & Practice (专业工程管理与实务, 120 pts, 2.5 hrs across 6 tracks: Building, Municipal, Highway, Water, Mining, MEP). Scores are valid on a rolling 2-year cycle; candidates taking all subjects must pass all three within two consecutive examination years. Provincial authorities determine annual passing score cutoffs, typically between 50% and 60% of total points.

What key national codes, standards, and decrees are evaluated on the exam?

Core standards and regulations evaluated include the PRC Construction Law (中华人民共和国建筑法), PRC Bidding and Tendering Law (招标投标法), State Council Decree No. 493 (Regulations on the Reporting and Investigation of Production Safety Accidents), MOHURD Decree No. 37 (Safety Management of Dangerous Part-Projects), GB 50300-2013 (Unified Standard for Construction Quality Acceptance of Building Engineering), JGJ 59-2011 (Standard for Construction Safety Inspection), and standard construction contract terms (GF-2017-0201).
