5D-based estimation of indirect construction costs: Development of an adaptive automation tool for improved efficiency of the ABK estimation process

One of the fundamental goals for the success of a construction project is found to be completion within the budget. To reach this goal, cost estimation is a key process which can be divided into the estimation of direct and indirect costs. Unlike direct costs, indirect costs are not directly connected with the performance of any particular...

Explorative case study to gain insight on the consequences of circular infrastructural construction projects: Investigating the effects of circularity in construction projects on project process and construction costs.

The aim of this research was to investigate the effects of implementing circularity in infrastructural construction projects. As a very polluting sector, circularity is becoming a more and more popular theme in the construction industry. Driven by both governmental regulations of reaching a full circular economy in 2050 and intrinsic motivation,...

Multidisciplinary Design Optimization of Timber High-Rise: Research and Development of a Multidisciplinary Design Optimization Tool

There are two main challenges in the construction industry: carbon emissions and densification in cities. Timber high-rise might prove as a suitable solution to both these challenges. However, there is a lack of implementation of timber high-rise. This research argues that a lack of thorough analysis of timber design alternatives in the...

Effect of the surrounding on the construction cost of district heating networks and similar infrastructures: Analysis based on drinking water and natural gas replacement projects

The 2-phased price determination process in Bouwteam projects in the Netherlands: An approach towards understanding the price in a construction project: Practical recommendations for the price determination process in Bouwteam

Bouwteam is a Dutch project delivery method that involves the contractor and the client in a collaborative way in a construction project's design process. With this early involvement of the contractor, this project delivery method contains two agreements during the project. The first agreement is for the contractor's involvement in the design...

Performance assessment of the Ocean Falls Wave Energy Converter: A solution for electrical power production in the future

There is a growing demand for renewable sources of energy of which wave energy conversion is one. The Ocean Falls is an oscillating water column (OWC) system invented by BAM Infraconsult b.v. This system differs from conventional OWC systems since it includes a connection tube and an adjustable back wall. The OWC system is a resonance system for...

Relationship Between Construction Costs and Reliability of Quay Walls

Structures have to meet a particular level of safety. Therefore, in the European design codes (Eurocodes), three reliability classes (RC) are introduced based on the potential consequence of failure of the structure. For each of the RC a maximum allowable probability of failure is introduced, corresponding to a reliability index. In recent...

Terminal Design Optimization: Adaptive agribulk terminal planning in light of an uncertain future

This study analyzes the financial impact of design guidelines used in the development of agribulk terminals and sets out to quantify the effect of uncertain throughput projections on a terminal’s business case. This was done through the use of a purposely-built computer model that translates traffic projections into a terminal design in an...

A Tool for Estimating Marine Terminal Dimensions and Costs in a Project’s Feasibility Phase: Taking into account uncertainties

The main objective of this study is the realisation of a computer tool. The function of the tool is to estimate the required dimensions and quantities of essential container, dry and liquid bulk terminal elements, in an early design phase. As well as to give an estimate of the construction costs of these marine terminals. Terminal element...

Prospective techno-economic and environmental assessment of carbon capture at a refinery and CO₂ utilisation in polyol synthesis

CO₂ utilisation is gaining interest as a potential element towards a sustainable economy. CO₂ can be used as feedstock in the synthesis of fuels, chemicals and polymers. This study presents a prospective assessment of carbon capture from a hydrogen unit at a refinery, where the CO₂ is either stored, or partly...

Optimal Vertical Extension: A study on costs and environmental impact for structural engineers

The motivation to adapt a building in terms of an upward vertical extension lies within the need for urban renewable programs. Although this practice has significant supports to make the built environment more sustainable, there are also barriers which invariably concern costs. In the case of vertical extension projects, the constructional and...

Advancing the roll-out of energy networks by embedding cost differentiation in modeling approaches which minimize assessed construction costs

This thesis aims to be a contribution to the roll-out of new energy networks by presenting and discussing ways to minimize assessed construction costs associated with these networks. It does this by providing an extension of already existing methods to estimate building costs.

Life Cycle Costs: A comparison between inflatable and traditional barriers

In December 2002 the highly innovative inflatable storm surge barrier near Kampen in the Netherlands was finished. This Ramspol barrier (named after the small villages next to it) has to protect the area surrounding the "Zwarte Meer" during north-western storms. These storms result in water setup that can cause severe problems for the very low...

Beschouwing van constructiekosten van monoliet golfbrekers

In deze studie zijn voor een fictieve golfbreker lay-out in relatief ondiep water de totale projectkosten tijdens de geplande levensduur van een conventionele stortstenen golfbreker, een caissongolfbreker en een samengestelde golfbreker vergeleken. De totale golfbrekerlengte van deze lay-out is circa 4000 m en strekt zich uit tot in een...

Comparison construction costs conventional rubblemound breakwaters/bermbreakwater

Given a harbour location and a wave-climate, two different types of rubble-mound breakwaters were designed. Using realistic quarry yield curves and prices for production, transport and constmction, the total costs of the conventional statically stable and dynamically stable bermbreakwater designs were compared to each other. This comparison led...
