5.3. Required Job Productivity

What is the required job productivity for that particular activity? So, that information you can get it from your contract documents. Your contract specifications will let you know like what is the schedule of your project from the work breakdown structure.

It is essential to understand the required job productivity for each activity in a construction project. This information typically comes from the contract documents. By analyzing the project specifications and the work breakdown structure, you can identify the allotted times and budgets for each task. This helps ensure that your equipment selection aligns with the expected output needed to meet project timelines and cost constraints.

Think of it like planning a school project where you have a deadline. Your teacher gives you a rubric that outlines what you need to complete and by when. If you know you have to finish the research part in a week, you’ll choose a research method that fits into that timeframe, similar to how contractors select equipment based on required job productivity.

You have to match your job productivity with the machine productivity. You have to select a measure of productivity to be matching with your job productivity.

Once you have determined the job's required productivity, the next step is to select equipment that can deliver this productivity. You need to understand how much work a specific machine can perform within a defined time and compare it to the requirements set out in your project plan. The goal is to choose the equipment that can effectively complete tasks within project parameters without exceeding costs.

Consider a baker who needs to make 100 cupcakes in two hours for an event. If the baker knows their oven can handle 20 cupcakes at a time and takes 30 minutes for each batch, they will schedule their baking accordingly. If they decide to use a different, slower oven, they may not meet the deadline, akin to choosing the wrong construction equipment for the job.

So the best choice of equipment will be the one which will complete according to your contract specifications within the time allotted in the contract at the lowest possible cost.

The contract specifications are crucial as they define the project timeline and budget. When selecting equipment, it’s vital to ensure that you choose machinery that meets these specifications. The chosen equipment should effectively perform the tasks needed within the time limits and budget constraints outlined in the contract. This will help avoid any delays or cost overruns.

Imagine planning a birthday party. If you only have a budget of $200 and need to provide a cake, decorations, and activities for ten kids, the right decisions (like not ordering a five-tier cake) are crucial. Similarly, contractors must carefully select equipment that can fulfill the project requirements without exceeding the budget.

Apart from all these things, the another important factor is your equipment selection should also consider the jobsite condition.

The conditions at the jobsite are a critical factor when selecting equipment. Factors such as the terrain, weather conditions, and accessibility can greatly influence equipment performance and productivity. Contractors must evaluate whether their chosen machinery can effectively operate under the specific site conditions to ensure smooth project progress.

Think about a gardener choosing tools. If the garden is in a rocky area, trying to use a standard spade may not be effective. Instead, they would need specialized tools to navigate the rocky terrain. Similarly, contractors need to select equipment that is suitable for the specific challenges presented by the jobsite.

So, having discussed about the general guidelines, which are to be kept in mind, now let us move on to the discussion about the important equipment selection practice.

After understanding job productivity, project specifications, and jobsite conditions, it's time to discuss the practical aspects of equipment selection. This involves carefully considering all factors to make an informed decision about machinery that will optimize productivity while remaining economically viable.

When coordinating a large event, after planning the entertainment, food, and venue, you need to review everything to ensure it all fits together. In construction, equipment selection follows a similar process, ensuring that the chosen equipment meets all project requirements and conditions.
