Study Notes

Introduction to Construction Projects

A construction project is a planned undertaking to build a facility or group of facilities.
Key participants include the owner, architect/engineer, consultant, general contractor, and subcontractors.
A successful project depends on understanding the project environment, roles, and responsibilities of all participants.
Various project delivery approaches and contract types are suitable for different project contexts.

Construction Industry History

Humans have built large structures throughout history, showcasing the ability to create and design for various purposes.
Twentieth and twenty-first centuries saw rapid advancements in technology and materials.
Large-scale constructions have significantly impacted human development.

Need for Management in Construction

The construction industry is the largest industry globally.
It's a service, not a manufacturing industry, as growth represents economic strength.
Disruptions in projects, e.g., cost overruns, time extensions, and conflicts among parties are widespread issues.
These problems stem from:
- The unique uncertainty of construction projects.
- The fragmented and competitive nature of the industry.
- Growing challenges faced by the industry as a whole.
Efficient project management is crucial for success.
- Handling complexities in modern projects
- Efficient use of resources (Manpower, Materials, Machinery, and Money)
- Meeting project deadlines
- Avoiding conflicts between project participants
- Improving construction quality and safety
- Achieving higher productivity
- Documenting past experience to improve future projects

Construction Project Participants

Owner/Client: The individual or organization funding and owning the project. Could be public or private.
Architect/Engineer: Designs the building's/facilities' appearance. Often consults engineers for structural, electrical & related designs.
Architect/Engineer (A/E): A firm with architects and/or engineers capable of doing complete project design
Construction Manager: Manages the overall construction process, from administration to material & method selection.
General Contractor (GC/Prime Contractor): Contracts with the owner to oversee construction of the entire project or a major part of it.
Subcontractors: Businesses contracting with the GC for specific tasks or materials in the project.
Project Manager: A person who coordinates all project facets, including planning, design, procurement, and construction.

Types of Construction

Residential construction
Non-residential building construction
Non-building construction

Life Cycle Stages of Projects

Concept Stage: Identifying needs and assessing various project alternatives. May take months to years, depending on factors like environmental assessments.
Design Stage: Working out detailed designs, specifications, service preparation, tender documents, and contracts.
Construction Stage: Actual construction, coordination, administration by the general contractor and supervising consultants. Commissioning and owner acceptance.
Operation & Maintenance (O & M): Activities after project completion, including operation and maintenance.

Project Contract Strategy

The contract strategy best fits the project needs when project managers are selected early on.
Choosing the right organizational and contractual policies for smooth project execution is key.
Key decisions include: setting project objectives, selecting a project delivery method, designing construction interactions, choosing a contract form, and administration practices.

Project Delivery Methods

Traditional Approach: Design first, then construction. Typically involves different firms for design and construction.
Design-Build: One firm takes responsibility for both design and construction.
Turnkey: A party contracts to fully design, build, and finance a project, transferring it to the owner afterward.
Professional Construction Management (PCM): The owner hires a PCM company to coordinate all stages, from design to final payment to contractors.

Construction Contract Forms / Types

Competitive Bidding Contracts: Two main types: Lump Sum and Unit Price.
Negotiated Cost-Plus Contracts: Deals where the owner shares project risk by reimbursing the contractor for actual costs + fee. Includes Cost + Fixed Percentage, Cost + Fixed Fee, Cost + Fee + Profit Sharing, and Cost + Sliding Fee.

Project Administration Practices: Contractual Relationships

Agent Relationship (A): Contract where a party (e.g., architect or engineer) acts on behalf of the owner.
Non-agent Relationship ($): Direct contract between the owner and the contractor to perform specified services.

Project Planning & Cost Estimation

Work Breakdown Structure (WBS): A deliverable-oriented breakdown of the project into manageable components.
Activity Relationships and Network Diagram: Establishing relationships between different projects so activities can happen in parallel, and identifying critical activities affecting scheduling.
Total Float Calculation and Identifying Critical Activities: Determining float and critical path to schedule to meet completion date.
Resource Histogram: A graphical representation of resources used along the project schedule.

Project Financing and Schedule Integration

Project Cash Flow: Difference between project income and expenses; graphical representations of expenses over time (S-curve) show how income and expense profiles vary based on payment cycles and project stages.
Time Period(s): Time units where income and expense changes are identified to help understand and account for project revenue and expenditures.
Cost estimation, Expenses, and Bid Prices: An understanding of costs and prices of each item in the project is imperative in creating an informative budget.
Project Financing Options: Methods for funding construction projects; include subcontractors credit, owner mobilization payments, front-end financing (bid unbalancing)

Earthmoving Operations, Materials, and Soil Characteristics

Earthmoving process: Movement and processing (excavating, loading, hauling, placing) soil/rock.
Equipment selection: Choosing the right equipment affects efficiency and profitability.
Production of earthmoving equipment: Calculating production based on output per cycle and cycles per hour, including efficiency factors.
Soil conditions: Factors such as trafficability, load ability, moisture content, and swell/shrinkage influence construction planning.
Soil classification: Categorizing soils. Systems like Unified and AASHTO help in planning and design.
Conversion of soil quantities: Conversion factors needed for conversions to different soil types (loose, compacted, bank).

Load Factors, Equipment, and Production

Load/Shrinkage Factors: Using factors to convert between different volume measurements of earth materials (loose, compacted, bank).
Excavating Equipment: Different types, including hydraulic excavators, draglines, and clamshells.
Production estimating: Methods for calculating the production rate per hour of each type of equipment.

Trenching and Trenchless Technology

Methods for digging trenches. Special trenching machines and plows are also in use.
Trenchless technology (also called trenchless excavation) also used.
Methods for installing utility lines below the ground as well.

Project Control (Earned Value)

Earned Value Analysis (EVA): Monitoring project status by comparing planned work against actual work performed and cost.
Key components for EVA include On-Progress, Work Scheduled, Work Completed, Actual cost.

Loaders, Trucks and Wagons, and Dozers

Loaders: Wheel and track loaders; loading material from excavation sites or hoppers.
Trucks and Wagons: Transportation of loads, calculation of required time, and number of vehicles.
Dozers: Tractor with a blade; used in site work, excavation, and earthmoving.
Cycle time, Load time: The various steps in these operations that need to be accounted for in overall estimating and scheduling.
Performance Curves: Used for loaders, trucks, and dozers to calculate maximum speed, given the required pull/resistance.

Specifications

Description of work: Clear, concise, and brief description of project requirements.
Types of specifications: Manufacturer's, standard, and contract specifications.
Materials & Measurements: Description, physical/chemical properties, workmanship.
Guidelines for Writing Specifications: Structure and content tips for writing good specifications; factors to avoid.

Quantity Surveying

Purpose of quantity Surveying: To assist in client budget, tendering, and measurement of accomplished work.
Steps of Quantity Surveying: Taking off, squaring, abstracting, writing the bill of quantities.
Principles of Measurement: Procedures for measuring quantities; considerations for each project item.
Take-Off Sheets: Format for recording work measurements.
