Construction industry is playing the role of an important pillar in today's economy. With the growing market and increasing complexity in construction projects, firms are vulnerable to swelling risks more than ever. A firm's decision to bid or not for a perspective project impacts both the project's success as well as generation of profit for the company. This study focuses to inspect the strategic intrinsic factors influencing the bid/no-bid decision of Pakistani contractors. A questionnaire survey sent to 300 contractors listed with Pakistan Engineering Council was used to collect data. "Financial position of firm" and "ability to fulfill the need of bid" in firm related factors, "management staff must know the conditions of the site" and "the project should increase the experience of the management staff" in management and carrying related factors, "method of bid evaluation of client" and "politician's pressure on the client" in client related factors were recognized to be the most critical intrinsic factors impacting the bid/no-bid decision of firms. Furthermore, the study identified that the bidding decision is highly dictated by the client and firm's internal environment. A better evaluation of these can result in better bidding decisions eventually leading to a higher project success rate in the industry.
