This was compared with propositions in analytical models, and significant differences were found. A total of 670 h of work observe

Bidding activities were categorized and their extent estimated as deskwork (32%), calculations (19%), meetings (14%), documents (13%), off-days (11%), conversations (7%), correspondence (3%), and travel (1%). Risk allowances of 12% were p

Although risk apportionment affects a contractors pricing strategy, other complex microeconomic factors also affect price. Instead o

These findings explain why some assumptions underpinning analytical models may not be sustainable in practice and why what actually happens in practice is

Most analytical risk models proposed by academic researchers have sought to prescribe how risk should be included in a bidding price. However, th

11、e actual process of how contractors and their clients negotiate and agree on price is complex and not clearly documented in most of the literature. As explained in a construction contracts textbook by Murdoch and Hughes (2008, p. 128), many contracts for construction work are created by the process

12、of tender, which often involves some form of market competition that clients use to obtain the lowest price from contractors. The fact that the pricing of work occurs in the tender process means that first, a basic understanding of the whole tender process used by contractors to arrive at a bidding

13、price is needed. Second, a basic understanding of how and in what circumstances price is influenced by the apportionment of risk is needed. However, little empirical research exists about the process used by contractors to put together a bidding price, as shown in Appendix I. Without a precise under

14、standing of how contractors price a bid and account for risks in reality, it would be difficult to conceptualize analytical models for approaching risk response in the way that it normally happens in practice. Risk assessment should have a serious influence on a contractors pricing strategy, but oth

15、er factors also affect price. The price clients are willing to pay for construction work depends not only on their available resources, but also on what other sellers (i.e., contractors) in the market are willing to offer for the same product. (See the microeconomic theory of the behavior of individ

16、ual competitive markets in Lipsey 1979, p. 93.) 2 A bidding price may be dependent on the market or competitive environment in which it takes place. Brook (2004) explains that bidding often involves two processes. First, estimating is the stage in which the actual project costs are considered. This

17、process may depend on the level of expertise in a contractors estimating department. Second, adjudication is the stage in which the directors of a firm take a commercial view of the estimated cost in the context of the firms particular circumstances, market conditions, and risk. Management will ulti

18、mately try to pitch the bidding price between cost and value to win the work. (See the explanation in Murdoch and Hughes 2008, pp. 138139.) The approach used by contractors to evaluate risk in the process of pitching their bidding price to respond to these factors is not always clearly explained in

19、the literature, as shown in Appendix I. However, several analytical approaches have been proposed to help contractors deal with risk when bidding.Without a sufficient understanding of how contractors actually price a bid and consider risks in reality, it would be hard to conceptualize analytical mod

However, as Skitmore and Wilcock (1994, p. 142) acknowledged, it is hard to get contractors to participate in studies of this nature primarily because of the commercially sensitive data involved. Several studies of contractors have shown that contrac

21、tors are often reluctant to fully account for the cost of risk in their bidding price to avoid inflating their price with risk allowances and become uncompetitive. See, for example, an interview study of 12 U.S. contractors by Smith and Bohn (1999) and a questionnaire study of 400 U.S. contractors b

22、y Mochtar and Arditi (2001). Thus, it is not surprising that several studies have shown that most contractors rarely approach the incorporation of risk in their bid proposals according to the contingency allocation theory prescribed by most analytical models. It also implies that other risk response

23、 mechanisms are probably used by contractors that could be shared and used to guide practical risk analysis techniques. Background Risk is a part of business endeavors because of uncertainty (Flanagan and Norman 1993； Fischer and Jordan 1996). Portfolio theory and capital market theory stipulate that total risk consists of
