What is LANDLOCK And How It Works?

 

LANDLOCK Advantages For Roads

Road designs vary greatly from country to country, but are generally calculated based on the performance metrics that need to be achieved. A super-highway will have a much larger profile of design than a rural road. However, all road profiles generally have three basic layers: a drainage layer, base and wear-course.

Just like a chain, every road is only as strong as its weakest link. Herein lies the problem. When a wear-course like asphalt begins to fail, evident by cracking and potholes, generally it is due to failures at the base or sub-base. Why then during construction would these critical layers only be compacted with water and therefore left “unstabilized,” and susceptible to water and vibratory erosion?

When integrating LANDLOCK into one (or all) of these three layers/sections of the road, it allows builders to gain several critical advantages that significantly reduce the traditional waste associated with modern road construction.

Advantages for Primary/Urban Roads & Highways

Profile Reduction

Based on extensive lab and field testing, a LANDLOCK® treated base will be 2-20 times stronger than an unstabilized base. This means that engineers can significantly reduce the profile of design of the road and still achieve the required performance metrics. A smaller profile of design means less material. At the same time, builders will see a reduction in material spreading and transportation costs, while simultaneously increasing production rates. The entire construction process is more efficient and less wasteful – Smarter Infrastructure.

Extended Life Cycle

As mentioned above, traditional wear-courses like asphalt are only as good as their base. It is only logical then that a wear-course laid on a rock-hard, erosion free LANDLOCK® treated base will last much longer than when laid on an unstabilized base. A longer life means less money being wasted on costly maintenance work, leaving more money to spend in other areas.

Advantages for Feeder/Farm-to-Market Roads

Paving/Stabilizing Dirt and Gravel Roads

Across the world, even in developed countries, there are millions of miles of unpaved roads that are a constant source of fugitive dust and waste given their need for constant maintenance. Because unpaved roads have no protection from rainfall, water erosion will turn a newly graded, rural road into a muddy mess, that once dried out, is then covered with potholes and washboarding. It is a vicious cycle that, previously, was impossible to win.

Organizational Structures, Advantages and Disadvantages

Organizational Structures, Advantages and Disadvantages

 

Each organization structure has its own set of advantages and disadvantages.

The advantage of functional organizations is that resources may find clearly defined career paths and achieve specialization and skill development in their respective fields. It will be a flexible work force since only one manager will be responsible, avoiding confusion.

The disadvantage of such organization type is that project work is hampered. Department work is always given higher priority than the project work. In addition, there is no career path in project management, which leads to lower interest in projects.

In the case of the projectized organization, one of the clear advantages is better communication within the projects. Since project work is the only work team members are doing, it also leads to loyalty towards the project goals.

The disadvantage of such organization type is the inefficient use of resources, because every project team has their own support function. Therefore, this might lead to the duplication of effort. It also leads to the resources being left with no work, since their roles are over once the project is completed. It also hampers skill development because the project requirements dictate what kind of work team members perform at different stages on a project.

 

Now, let us look at the matrix organization. It also has the advantage of better coordination and maximum utilization of resources. However, the disadvantage is the higher potential for conflict among the managers, which might lead to communication complexity and overhead management.

Organization Structure: Matrix Organization

Organization Structure: Matrix Organization

 

In a matrix organization, the resources report to the functional managers and are managed by the project managers as well. There might even be a function that represents all the project managers in the organization, which provides project management expertise.

The matrix structure has three variants commonly referred to as weak, balanced, and strong. In a weak matrix, the authority of the project manager is the weakest, and strongest in a strong matrix structure.

The titles given to project managers in functional or weak matrix organizations are project expeditor or project coordinator. They would be called project managers in a balanced or strong matrix structure and have slightly more authority over the time of the team members.

The advantage of the matrix structure is that resources can be optimally utilized, while preserving the capacity of the project managers to get projects executed efficiently. Resources can specialize in their functions and have stability in their careers, also contribute to the projects at the same time potentially.

The disadvantage of matrix organization is that the communication overhead increases significantly. This is because every resource in the organization belongs into a project and into a function, leading to a dual reporting structure.
In a matrix organization, project management happens at Project Resource Level.

Organization Structure: Projectized Organization

Organization Structure: Projectized Organization

 

The projectized organization has all the resources aligned around projects.

The project managers have complete control over the resources working on their projects.

The biggest advantage of the projectized organization is that the resources have loyalty to their projects and project execution becomes easier. This kind of structure is suitable for organizations whose work is in the nature of projects.
There are few disadvantages in this structure as well. Firstly, the role of the resource is over once the project is completed. Secondly, highly specialized roles within a project may not be fully occupied all the time.

For example, a purchase executive may have work for selected periods on a project while purchase activities are going on. However, for the rest of the period, their capability may not be optimally utilized. There is less scope for functional specialization, as the project boundaries limit the kind of work for the resources.

Each project manager is in-charge of a project and its resources.

Organization Structure: Functional Organization

Organization Structure: Functional Organization

 

In a functional organization, the resources of the organization are grouped by “functions” – sometimes called departments. Examples of functions could be “sales”, “finance”, “administration”, “manufacturing”, etc.

Each function plays a definite role in the organization and is headed by a functional head or supervisor.
All the resources in such an organization report directly into their functions. Therefore, a sales person would report into the sales organizational hierarchy, a purchase executive would report into procurement, and so on.

You would notice that in a functional organization, the project manager’s role is not explicitly called out. When a functional organization embarks on a project, each of the functions that are involved may volunteer some resources to work on the project. One of these resources may end up playing the project manager’s role. The resource assignments may not even be full time and sometimes even the project manager is part time.

Since the project manager has no authority over any of the resources, they are dependent on the functional heads. This makes it more challenging for the project managers to coordinate in the team.

However, functional organizations provide an opportunity for specialization. For example, if a purchase executive was reporting into the purchase department, that executive would have exposure to all the purchasing that happens within the organization and has a well-defined career path.

In functional organizations, project management happens at the Functional Head level.

Organization Structure: Functional, Projectized, Matrix

Organization Structure: Functional, Projectized, Matrix

 

Projects are performed in an organization and the functioning of the organization might affect the project.
The different organization structure types explained here are based on the level of authority that a project manager gets into those organizations.

In a functional type of organization, the organization is grouped by the area of specialization within different functional areas. For instance, marketing, accounting, engineering, etc., are departments within the organization. Each employee typically reports to a functional manager.

In such types of organization, normally projects are undertaken within the department itself. If a project requires any assistance from another department, the request moves from the head of the requesting department to the head of the concerned department. The team members do their normal departmental work in addition to the project work.

The next type of organization is projectized organization. In such organizations, there are no departments. The organization’s resources mostly work on projects. Team members report to a project manager. The project manager has complete control over the resources. When the project is completed, either they move on to another project, or they look for some job outside the company. They do not have a department for themselves.

The third type of organization is a matrix organization, which is a blend of functional and projectized organizational structure. A team member belongs to a department as well as they are part of a project team. In such organization, team members have two bosses, one, their department head and the second, their project manager.

Since there are two bosses here, this type of organization is further classified into three different types.
They are weak, strong, and balanced matrix organization. So out of the two bosses that team members have in matrix organization, if the project manager has more authority over the team member, such organizations are called strong matrix; where the functional manager has more authority, it’s a weak matrix organization. If they both share equal authority, than it’s a balanced organization.

There is another term that you might find in the exam, called “tight matrix”. This generally refers to a “co-located” team, i.e., a team that has been placed in the same location to enhance their performance.

Beam reaction analysis Spreadsheet

 

Beam reaction analysis  is a spreadsheet program written in MS-Excel for the purpose of determining the allowable beam end reaction and the allowable end moment for the purpose of end connection design.

This program is a workbook consisting of two (2) worksheets, described as follows:

  • Doc – Documentation sheet
  • Allow. Beam End Reaction – Allowable beam end reaction and end moment

Program Assumptions and Limitations:

1.   This program uses the database of member dimensions and section properties from the “AISC Shapes Database”, Version 3.0 (2001) as well as the AISC 9th Edition (ASD) Manual (1989).

2.   The user may select from W, S, M, C, and MC shapes.

3.   This program utilizes the procedure which a steel fabricator would typically use to determine end connection design loads when end reaction values are not specified on the design and construction drawings by the engineer.  This procedure is based on the AISC 9th Edition (ASD) Manual (1989) Allowable Uniform Load Tables on pages 2-36 to 2-140 and AISC Specification Chapter K, pages 5-80 and 5-81.

4.  This program contains “comment boxes” which contain a wide variety of information including explanations of input or output items, equations used, data tables, etc.  (Note:  presence of a “comment box” is denoted by a “red triangle” in the upper right-hand corner of a cell.  Merely move the mouse pointer to the desired cell to view the contents of that particular “comment box”.)

All the worksheets are independent and self contained, so that you can move them from one workbook to another. All the worksheets are protected, but not with a password.
