Medical Microbiology Bacterial Infection and Immunity summarizes and organizes knowledge points to help learners understand and remember. Study more efficiently!
The kinetic theory of gases reveals the microscopic nature of macroscopic thermal phenomena and laws of gases by finding the relationship between macroscopic quantities and microscopic quantities. From the perspective of molecular motion, statistical methods are used to study the macroscopic properties and change patterns of thermal motion of gas molecules.

cost management
cost management tasks
1.Construction cost
Direct costs: people, materials, machines, etc.
Indirect costs: management salaries, office expenses, travel expenses, etc.
2. Control the cost within the planned range while ensuring that the construction schedule and quality meet the requirements.
3. The establishment of the cost management responsibility system is the most important basic work
4. Tasks of cost management
①Cost planning preparation
②Cost control: Construction cost control from bidding stage to deposit return
③Cost accounting
two links
1. Collect and distribute construction costs
2. Calculate the total cost and unit cost of the project
Generally targeted at unit projects
The project management organization should carry out the work according to the prescribed accounting cycle
completed project
On-site costs: Project management agencies assess project management performance
Complete cost: Corporate finance department assesses corporate operating efficiency
④Cost analysis
Compare the project's cost accounting data with target costs, budgeted costs, and actual costs of similar projects
Analysis is the key and correction is the core
⑤Cost assessment
cost management measures
1. Organizational measures
1. Prepare cost management work plan and determine work process
2. Make a good purchasing plan and optimize the allocation of production factors
3. Strengthen the management of construction quotas
4. Strengthen construction scheduling and reduce work delays, etc.
●Organizational measures are the prerequisite and guarantee. If used well, they will not increase costs.
2.Technical measures
1. Technical and economic analysis to determine the best construction plan
2. Combine construction methods to reduce consumption costs
3. Determine the use plan of mechanical equipment
4. Combined with construction organization design
5. New materials, new technologies, etc.
3. Economic measures
Funds, resources, owner visa, etc.
4.Contract measures
Contract structure, claims, etc.
cost planning
1. Divide according to the role played
1. Competitive cost planning
1. Construction project bidding and contract signing stage
2. Estimate the cost, which is generally rough.
2. Instructional cost plan
1. Budget cost plan during the project manager selection stage
2. Project manager’s responsibility cost target
3. Based on the contract price and the company’s budget quota standards
4. Use this to determine the total cost target of responsibility
3. Implementation cost plan
1. Construction budget cost in the construction preparation stage
2. Based on the project implementation plan
3. Starting from the implementation of the project manager’s responsibility objectives
4. The main basis is the construction budget
2.Construction budget
1. Content
1. Preparation instructions
2. Budget tables: project quantity calculation summary table, construction budget quantity and material analysis table, labor summary table, material consumption summary table, mechanical shift usage summary table, construction budget table
2. Comparison of "two calculations"
1. The basis for preparation is different: construction budget: construction quota construction drawing budget: budget quota
2. Scope of application: construction budget is used for internal management of construction drawing budget: applicable to both the employer and the contractor
3. Play different roles: Construction budget: Contractor’s specific internal work construction drawing budget: Tender quotation
4. Comparison methods: physical comparison method and amount comparison method
5.Contrast content
1. Comparison of labor quantity and labor cost: The labor quantity in the construction budget is lower than the construction drawing budget
2. Comparison of material consumption and material costs. The material consumption and material costs of the construction budget are lower than the construction drawing budget.
3. Comparison of construction machinery and equipment costs
4. Comparison of turnover materials
3. Divide by stages
1. Prepare cost plan according to cost components
2. Prepare cost plan according to project structure
3. Prepare cost plan according to project implementation stage (progress)
●Extended on the basis of the network diagram for controlling project progress
1. Cost plan histogram prepared by month
2. Time-cost accumulation curve (S-curve)
1. Determine the progress plan and prepare a horizontal bar chart of the progress plan
2. Calculate the cost per unit time (month or ten days) and prepare a cost expenditure plan
3. Calculate the cost amount of planned cumulative expenditures
4. Draw an S-curve
1. The S-curve is enveloped in a banana diagram composed of the earliest and latest start curves of all work.
2. By adjusting the earliest or latest start time of supply and demand projects on non-critical lines
3. Starting all work at the latest will help save loan interest, but it will be detrimental to the guarantee rate of completion on schedule.
●The three cost plans are not independent and should be used together
