Project Management

Modern management of a development project requires an up-to-date knowledge of design, efficiency, construction techniques, marketing and cost controls. Proper application of the principles of project management ensures that the development will be completed within the allocated time frame and budgeted costs.

Project management in OTN is a professional approach in the co-ordination of all the skills necessary to identify and achieve the clients’ or employers’ objectives and to attain successful accomplishment of the developments.

The relationship between the Project Manager and his principal is clearly defined from the start. As he represents the Client or Employer, his role is therefore that of a leader and co-ordinator of the development team. It is important that he shows understanding and respect to the disciplines of the respective members of the team but it is undesirable if he personally fulfils any of the individual functions. Where the services of other professional consultants with particular skills are required, he will be required to enlist such assistance.

Being trained and experienced, the personnel of the Project Management Team of the firm are closely involved in the construction industry and are well aware of the various aspects of building costs, valuation, investment potentials, land utilisation, marketing and management of completed buildings.

As Project Managers, we would include in our brief, the following duties and responsibilities:

  • definition of objectives.
  • preparation of economic and viability studies, taking into account prevailing and future market conditions,  and if appropriate marketing requirements and arrangement of finance.
  • co-ordination of the design process and the obtaining of the necessary consents.
  • monitoring progress of building works and execute regular reviews on the construction and financial status of the project; and providing input in the drawing up of an overall marketing plan and management of the completed development.

 Feasibility Study

A rational approach towards ensuring the success of a development project must require economic and financial appraisals to be carried out before and during the concept stage. These exercises enable the developer to establish his objectives. Thereafter, it will be necessary for these appraisals to be reviewed and up-dated at regular intervals.

The vital areas covered in a feasibility study shall include:

  • its capacity analysis to determine the design concept and optimum envelop of the building structure(s).
  • surveys to determine market trends in supply and demand and the capital growth rates in the industry.
  • market studies to ascertain the marketability and viability of the proposed development.
  • Financial appraisals to determine the total development costs, capital structure, loan requirement, the estimated profit margin or investment return arising from undertaking the proposed development.
