The paper outlines the findings of an investigation into the use of dayworks sheets by a UK National Management Contractor. The investigation was carried out using interview techniques and ethnographic research to gain an insight into how practicing quantity surveyors conceived of the use of dayworks sheets. The use of dayworks sheets in construction contracting is both widespread and widely ac...

With the continuous development of construction industry, current production mode is gradually transforming into contractor, professional subcontractor and labor subcontractor’s “main-sub contractor” cooperative in market segmentation. Long-term cooperation between contractors subcontractors beneficial to both parties, yet only limited research has explored factors that determine contractors’ w...

Construction contractors significantly contribute to the progress and success of projects. Contractor prequalification grants tendering rights only competent contractors. The bidding process is one most critical phases in construction industry. project leader must assess general, technical, financial information prepare an accurate proposal select best contractor. In this study, contractor cons...

In forest operations, the interface between forest companies and harvesting contractors is of special importance, considering that it is the first link in the forest industry’s supply chains. Supply operations account for a significant share of the final costs of wood products (up to 50%). This study investigates the effect of customer–contractor alignment on contractors’ profit margins and on ...

This article presents the resource-constrained project scheduling problem with discounted cash flow maximization criterion from perspective of a contractor. Cash flows are considered as contractor’s expenses related to execution activities and client’s payments (revenue contractor) after completion contractual stages. To solve problem, dedicated techniques generate solutions simulated annealing...

Purpose Innovation during project delivery is contested space. The aim in this research to empirically explore the theory of space and how implementation can be optimized by contractor deliver better outcomes. It hypothesized that innovation has a proportional measurable relationship success. Design/methodology/approach Based on novel conceptual framework, applies case study methodology analyse...

In the construction industry, evaluating the financial status of a contractor is a challenging task due to the myriad of the input data as well as the complexity of the working environment. This article presents a novel hybrid intelligent approach named as Evolutionary Least Squares Support Vector Machine Inference Model for Predicting Contractor Default Status (ELSIM-PCDS). The proposed ELSIM-...

Nonlinearity, uncertainty and subjectivity are the three predominant characteristics of contractors prequalification which cause the process more of an art than a scientific evaluation. A fuzzy neural network (FNN) model, amalgamating both the fuzzy set and neural network theories, has been developed aiming to improve the objectiveness of contractor prequalification. Through the FNN theory, the...
