In construction industry, business failures are generally resulted in payments withheld or refused to be paid. By taking advantage of blockchain technology, cryptocurrencies and smart contracts in this industry such problems could be mitigated. Within the proposed framework, funding of each item of the contract is blocked unless the contractual conditions agreed upon are fully satisfied. Set of instructions and conditions could be coded in smart contracts such that payment will be made automatically only when the stipulated conditions are reached. This concept guarantees establishing a trustful chain of payments between the parties. Proposed concept also minimizes the time-cost overruns due to dispute reduction and maximize the trust between contract parties in construction industry. Although the construction industry is recalled as being slow at adapting to new technologies, the prospect of having a protection against late payments might be a driving force for acquiring the smart contracts. The proposed framework is and pros as well as cons of this framework is discussed in this study

Smart contract systems for guaranteed and timely payment of construction projects
Ahmadisheykhsarmast, Salar; Sönmez, Rifat; Department of Civil Engineering (2020)
Delay in progress payment is a widespread problem in the construction industry which adversely affects the entire processes of the projects. Difficulties in the cashflow of the contracts, and consequently the subcontractors are the main consequences of delayed payments. Despite its significance, few research focused on development of methods guaranteeing timely payments of the participants throughout the project. Recent developments in blockchain and smart contract technologies presents a potential for deve...
Hybrid particle swarm optimization algorithm for obtaining pareto front of discrete time cost trade-off problem
Aminbakhsh, Saman; Sönmez, Rifat; Department of Civil Engineering (2013)
In pursuance of decreasing costs, both the client and the contractor would strive to speed up the construction project. However, accelerating the project schedule will impose additional cost and might be profitable up to a certain limit. Paramount for construction management, analyses of this trade-off between duration and cost is hailed as the time-cost trade-off (TCT) optimization. Inadequacies of existing commercial software packages for such analyses tied with eminence of discretization, motivated devel...
Integrated Approach to Overcome Shortcomings in Current Delay Analysis Practices
Birgönül, Mustafa Talat; Dikmen Toker, İrem (American Society of Civil Engineers (ASCE), 2015-04-01)
Many factors, such as unforeseeable events, managerial and financial problems of contractors, insufficient technical capacity of site teams of contractors or Consultants, and so on, may lead to delays in construction projects. Proper analysis of compensability and quantum of a delay event is of prime importance. Any delay analysis application can be considered as a result of the combination of contract documents, scheduler, record-keeping mechanism at the site, communication among project participants, dela...
Development of an IT-based tool for portfolio assessment and management for construction companies
Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019)
Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
Quantification of Acceleration Claims: a Simplified Approach
Ilgar, Ali Özge; Birgönül, Mustafa Talat; Department of Civil Engineering (2005)
Operating a successful business within the construction industry has become more difficult for companies as the profitability margins decreased considerably compared to previous years. Even, global economy has created an environment in which construction firms are enforced to bid projects at or below lowest profit levels. At the same time, owners are demanding more difficult projects without increasing the quality of contract documents. This has placed an added burden on the individual contractor to constru...
