Satisfied Female Owner

For Owners

Most owners can recognize the fact that there are major challenges in terms of schedules in the Danish construction industry. Studies show that all schedules are exceeded by an average of 17%. But despite that trend, traditional consultants continue to recommend and choose to use traditional management tools like Gantt. These consultants often fail to hoist the red flag and draw attention to consequential deviations before it is too late.

Planning with traditional schedules often results in poor utilization of the entire construction site. Some areas are deserted, while other areas are overcrowded with contractors getting in each other’s way. The consequence is time waisted and delayed delivery.

Location-based scheduling is a visual method that gives you a far better overview of your schedule than traditional methods. Delays, colliding activities, and other scheduling challenges will emerge early on, and can anticipate serious problems down the road, long before they occur. This gives you time to take constructive discussions with the contractor about order, flow in activities, staffing, productivity, follow-up, and progress in the construction.

With the Location-based planning method, you get equipped with a detailed overview, to make wise decisions and ensure that the tasks regarding. your project will be solved in the most efficient order.

A General Contractor At The Construction Site

For General Contractors

For General Contractors the location-based method is all win! There are literally no downsides. When converting a Gantt time schedule to a location-based schedule, you will be able to reduce your construction period with up to 20%. Going from 20 months construction period to 16 moths, will save you and your firm a lot of money. And – as a side benefit – this will also reduce your CO2 emissions significantly.

With Location-based scheduling, you will be able to identify critical issues early – in time to correct. A real life example: A subcontractor, a plumber, is contacting the General Contractor for a request. He asks for an additional few days per bathroom in a large residential complex project. The GC finds it positive, that the plumber reaches out beforehand, and would like to try to meet his request.

But when they sit down, and make a forecast with the updated data, they can see, that this small adjustment would caused an overall delay of the entire project of 3 months. The plumbers request has to be denied, but he understands why, and he agrees to man-up his crew instead. These derived effects of one small adjustment are impossible to foresee with Gantt.

A Happy Trade Contractor At A Construction Site who has benefitted from Innovative Construction Solutions

For Trade Contractors

Feedback from both GC and TC are, that the environment on site is so much better using this method of planning.

Without adding more men on site, you as a subcontractor will be able to optimize your work and reach your deadline, simply by exploring all corners of the construction site, and securing that no activities collide. This gives all subcontractors space and time to work in a good flow without disturbance, and allows them to be able to keep a good rate.

A good flow for each subcontractor is crucial for the entire schedule to succeed.

The data driven engine behind the schedule, and the visual showing of consequences of delays, make it so much easier to understand the need for e.g. upscale or downscale of manpower. There is less arguing, and the subcontractors are happy to be able to keep their flat fee and their good flow. Gantt planning often leaves gaps with time wasted and time waiting.

As a subcontractor you will find peace in your workday and do not need to jump randomly around the site to find a free corner to work. You will have a given space on a given time exclusively for you, with time and quiet to finish you job in an orderly manner. Giving you a more satisfying work day, with good results in a good quality.

Engineers And Architects Working With Construction Management and Developing Innovate Solutions for Construction

For On-Site Management

If you are an architect or an engineer in the role of construction management on site, and responsible for the time schedule, location-based scheduling gives you a much better overview of progress and issues than the traditional Gantt chart. The method is visual, and the consequences of a delay, and a solution of how to mitigate them, is very easy to identify. A complex time schedule will fit on a single page only.

If you are the one responsible for scheduling on site, you will be able to provide both the contractors, and your client – with a simple and optimized time schedule, including the best possible flow between disciplines and tasks, and a minimum number of risks. Any planning flaws/errors will appear visually and will be easy to identify and eliminate.

This method is proven to reduce conflicts and promotes a good and healthy work environment on-site. If the contractors have a request or a claim, it is very easy to visualize and communicate the consequences of a subcontractor’s delay etc. When meeting coordinating on site, most construction managers have heard from a delayed contractor: “Yes, we are delayed, but we will make it, don’t worry”. With this method it is easy to check whether this is a realistic statement or not. The method will show you historic data – e.g. progression rate of this particular contractor. Is a higher progression rate with the same number of workers realistic? Furthermore, you can, in real time at the coordination meeting, make a projection of the time schedule. You will be able to visualize the effects of this delay, which will act as a visualization of the consequence for the subsequent activities.

Infrastructure projects can benefit from linear scheduling

Infrastructure

While CPM has been used on countless projects, it has been found inadequate when scheduling linear projects. Linear projects are those that have repetitive activities.

Read more...

Road projects, tunnels, and pipelines are physically linear projects that have the same operations repeated at each station. High-rise buildings have the same activities occurring on each floor.

The inability of CPM to accurately model the repetitive nature of linear construction include:

  • the arbitrary division of repetitive activities from location to location,
  • the inability to schedule the  continuity of resources,
  • the large number of activities necessary to represent a repetitive or linear project in a CPM schedule,
  • activity rates of progress not indicated,
  • a CPM schedule not accurately reflecting actual conditions, and
  • a CPM schedule not providing any information on where on the project site the work is currently being performed. 

Tactplan offers a solution to the problems with CPM scheduling. Using Tactplan, you can convert your Gantt Schedule to Line of Balance (Flowline). When Tactplan is used, continuous, or repetitive, activities need not be arbitrarily interrupted, ressource continuity can be maintained, and the location of the work in progress on any given day is easily determined from the schedule.

The offshore and onshore wind turbine system can be optimized using location based scheduling

Wind Turbine Installation

Excerpt from article in Building Supply. PhD Jon Lerche on construction management – including location-based scheduling – in the offshore industries.

Jon has formed an understanding from the experience of the construction industry and sought to transfer known methods to the offshore industries: Oil, gas and wind, where he operates daily. He quickly found that many of the challenges faced in production systems are almost identical across industries.

In connection with a case study, Jon Lerche found that location-based time planning is one of the tools that can optimize project planning and thus the production system, because the method can create a pace in the tasks. An overall control. In connection with the case study in question, he made a risk analysis of the schedule when establishing a wind farm.

“Based on the location-based method, I was able to quickly identify a number of serious challenges in the schedule. Some areas were overbooked, so artisans had to wait for other craftsmen to finish, while other areas were left unused. With better planning of resources, there could simply be a significant reduction in staffing, without extending the construction period”, says Jon Lerche.

Education and continued dissemination of positive experiences must draw a new reality. And then we have to make the benefits very concrete. A reduction in resources from 80 to 20 men within the same time frame – it is understandable – and it is difficult to say no to. Or that 5 men sit still for 14 days because the craftsmen in front of them are not finished. These are the kind of concrete examples that can change mind-sets.
