2. Introduction & Background Construction industry´s focus on preplanning
THIS IS A DARKBLUE CIRCLE
WITH TEXT
Construction industry´s focus on preplanning
Improved quality, cost and project duration.
Advantages and disadvantages by preplanning.
Paper aim: review gaps in the literature for study
experience with preplanning in construction projects and processes.
Relation between preplanning stimulate use of prefabricated construction systems.
Obtain finding´s and put it in perspective to gaps.

4. Litterature review Cost and scheduling increase:
Global challenge 5 continents, 20 nations.
Project scope changes increase cost and schedule.
Ability to manage scope changes determine the success.
Planning and scheduling:
Positive impact on effort spend on preplanning and cost performance.
Reduce risk and budget 10-15%, improve quality 5-10%.
Pre-assembly construction:
mixed Pre-assembled components and computer-aided design
reduce Time and cost.
Stable processes less “fire fighting management”.

5. Litterature review Productivity:
Productivity calculations at macro level is unreliable.
Focus on planning, control and risk improve productivity.
Improved productivity by reduced weight, and build ability.
Risk planning:
Risk tools are a combination of political, economic, social, technological, legal and environmental factors.
A business culture with a industrial context to manage risk.
Technology:
No evidence, construction is worse / better than manufacturing to innovate and perform.

6. Discussion & Conclusion
experience with preplanning in construction projects and processes.
Linear positive impact to improve cost and quality, and reduce duration and risk in process.
Relation between preplanning stimulate use of prefabricated construction systems.
Not found, but advantages by offsite construction by stimulating the preplanning process by less fire fighting management.
Obtain finding´s and put it in perspective to gaps.
Found relevant results for indicating that preplanning have several advantages to construction projects.
