Executive Summary

One of the critical topics that was discussed in chapter 3 “Cornerstones of Efficient Site Operations” is supply chain management. The principle of supply chain management can be applied to all projects ranging from project such as building of airports, rails, road, schools, hospitals, bridges, to hotels. Supply chain management if properly done can save a lot of time with delivery of materials to site.

Another thing that was looked at was constructability. Constructability has the meaning of using an effective approach in the construction project process from beginning to finish by ensuring each stage is investigated by experience professionals to identify “pit-falls” and correct them to maximize effective project process before it even begin. Constructability ensures the project team maximize the simplicity, economy, and speed of construction, while considering the site conditions, code restrictions, and client requirements which increases the probability of project success, reduce construction waste, and improve building performance. The concept of constructability in project management begin with good planning before project begins, identifying the extent to which a design facilitates efficient use of resources to enhance ease and safe on construction site. The concept is also the integration of construction knowledge and experience in the planning, design, procurement, and construction phases.

Also, the five phases of construction project were looked in to and this includes planning, design, construction, operation, and decommission

1.0              Weekly Review

1.1              Class Happenings

The class started with a review of the lesson 1. The impacts of the construction industry resulting from the widespread adoption of BIM was describe and the impacts to the construction industry resulting from the drive towards sustainable and eco-efficient construction was also described. The way productivity is measured in the construction industry and the use of scientific methods to measure how well construction is progressing was also discussed.

Key learning from the group discussion from lesson 1 was also mentioned with emphasis on the importance of BIM in the future, effect of technology on production, sustainable certification, and IT and focus on tasks. To conclude on the review from lesson 1, it was reinstated that each project needs its own evaluation and there are certain things that needs to be considered in evaluating which includes the methods to increase output, methods to reduce waste and costs, and tools best suited to increase efficiency.

The topic for the week was then introduced as cornerstones of efficient operation.

1.2              Expectation from the class

It is expected of students to research additional materials for additional depth of content for textbook, supplemental reading or lecture topics relating to the lesson.  I am expected to be able to understand the concept of constructability and how it relates to improving efficiency. Also, supply chain management, construction project phases, and engineering design process should be studied and understood.

2.0              Personal discussion

2.1              Reflection on constructability

This second lecture as opened me up to the concept of constructability. Constructability is defined by the Construction Industry Institute (CII1987) as the optimum integration of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives and improve building performance.  Constructability can help figure out the challenges that will be encountered in a project even before the start of the project. This helps with reducing or preventing errors, delays, wastes, and cost overrun during the execution stage of the project.

Reflection on supply chain management

Supply chain management deals with the planning and integration of activities such sourcing, procurement, and coordination of material delivery. Procurement and supply of materials involves quite many logistics because the process may require multiple parties such as the owner, general contractor, subcontractor and the supplier. The importance of supply chain management should never be underestimated as a proper supply chain management can result in lower cost for the project due to lower supply chain cost, lower production cost and lower cost of materials which will then result in an increase in profit leverage and cash flow. Supply chain management can be improved by understanding and coming up with a very good underlisted;

·         Supply chain strategy

·         Supply chain network design

·         Supply chain service performance

·         Supply chain cost

·         Supplier performance

·         Ethical procurement and corporate responsibility

·         Inventory management.

Relation of the material to past knowledge

The course material as opened me to the importance of supply chain management and the things to consider when coming up with a good supply chain management. This wasn’t something I would have considered before now if I were to make procurements. Also, with the fact that almost everything needs to be optimized this days for better performance and productivity, this new knowledge gained about constructability cannot be underemphasized.

Real World Problems that can be solved

Lack of coordination during procurement and delivery is a major problem that can cause delays to any project. This problem can be solved through a proper supply chain management process. Applying a proper supply chain management can lead to the development of internal capacities to carry out processes in a more effective and efficient way than that of competitors, development of strategies that will allow better delivery of products and services to targeted market segments and the effective organization and handling of information and resources flows needed to improve performance of the suppliers.




2.2              Best approach that enhanced my understanding

The class slide presentation and lecture enhanced my understanding of the topic. Also, the writing of this Journal gave me more opportunity to revise the textbook and reflect on the discussion postings.

Steps to implementing supply chain management

The implementation of supply chain management might be limited by quite several factors which includes but are not limited to;

·         Deficiency of Integration and coordination: Most of the companies are quick to point fingers when there is a supply flaw to the supplier without looking at their own internal deficiency, like the lack of planning and control, inadequate communication, and changes to supply needs. Some companies do not have the intention of creating long-term relationships with supplier.

·         Poor understanding of the way each of the parties participates in the supply chain: Companies have the important role of improving the relationship with their supplier with specific emphasis on providing clear requirements, to avoid continuous change of design and supply needs and to create adequate communication channel to improve the critical conversations with their suppliers.

·         Insufficient application of sound management principles and methodologies for managing respective companies: This is an issue that should be addressed if it is hoped to be successful in the application of supply chain management.

When these limitations have been addressed, then a proper supply chain management can be proposed and adopted. The Deming cycle, also call the Plan-do-check-act (PDCA) cycle can be adopted when coming up with a good supply chain management. The Deming cycle is focused on strengthening four aspects: strategic planning, coordination, and effective collaboration, focus on the client, and information integration. These four aspects should be considered and measured by construction companies to reach the potential benefits of keeping good relationships with suppliers and clients. The steps in implementing a good supply chain management is as follows;

1.      Initial analysis of the supply chain: The objective of this stage is to define the supply chain of the organization having three things in mind which are;

·         Analysis of organizational structure and strategic planning: This will result in mission, vision and strategic objectives focused on improving relationships with suppliers and clients and, redesigning of organization focused on clients and suppliers.

·         Identification and description or supply chain processes:  This will result in the definition of responsibilities, identifying the critical processes and sub-processes that belong to the supply and defining processes relationships.

·         Identification of waste in the supply chain: This results in identification of activities that do not add value in the supply chain and detection of problems in the interactions between production flows and conversion.

2.      Planning and design of the supply chain: At this stage objectives and action plans are generated. This may include the application of management process, process improvement or redesign, integration, and coordination of strategies, and the identification and generation of performance measures. Some of the things to have in mind and result to expect at this stage includes;

·         Using IT to regulate information flow

·         Satisfying client’s requirement

·         Improving client-supplier relationship

·         Reducing waste in transformation and flow process

·         Integrating and coordinating suppliers and clients’ activity

·         Generating qualitative and quantitative performance indices for supply chain.

3.      Action implementation: The purpose of this stage is to carry out the activities or strategies that were defined and adopted in the planning stage. It also considers the construction of the necessary capacities related to the use and management of technology, capital, people, and resources to assure an effective implementation.

4.      Monitoring and control: At this stage the obtained results are compared against planned results using performance measurements. If this comparison is not positive, then corrective actions should be taken but if the results are as expected, then new actions are planned to continue improving the supply chain.

4.0              Key Terms and Concepts

4.1       The Meaning of 10 Key Terms or Concepts Related to the Lesson

            The following are the list of terms;

1.      Supply chain management: Is the planning and integration of activities involved in the sourcing, procurement, and logistics of construction material; mechanical systems; parts, prefabricated work-in-process (WIP), and information (Abourizk, Bernhold, 2010).

2.      Constructability: Construction Industry Institute (CII1987) defines constructability as the optimum integration of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objectives and improve building performance. 

3.      Planning:  It is the process of thinking about and organizing the activities required to achieve a desired goal. It involves the creation and maintenance of a plan, such as psychological aspects that require conceptual skills.

4.      Design: A plan or drawing produced to show the look and function or workings of a building, garment, or other object before it is made.

5.      Construction: The action of building something, typically a large structure.

6.      Decommission: Planned shut-down or removal of a building, equipment, plant, etc., from operation or usage.

9.      Management: The organization and coordination of the activity of a business in order to achieve defined objectives and goals.

10.  Efficiency: It is the (often measurable) ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.

11.  Management: The organization and coordination of the activity of a business in order to achieve defined objectives and goals.

5.0              Favorite Sketch/ Picture

The figure below is my favorite picture for the week. It shows a web that is centered around application of supply chain management paying attention to the four proposed critical factors that should be determined while applying the supply chain management. The four critical factors are; information integration of the whole company, operational coordination and collaboration, focus on the client and development of general strategies in the w hole chain

6.0              Supplementary Materials/Observation

The textbook discusses a variety of subject matter on constructability and how it can lead to an improved efficiency. Also, the importance of supply chain management can should never be under estimated as not having a proper supply chain management can lead to a delay in supply of material to a job site which will in turn means a delay in project delivery.
