Commercial Interiors | Tenant Fit-up | Retrofit | Custom Projects

Commercial construction has been our specialty for many years and we understand that it can be simple or complex. Our well trained managers, staff, and crews have the ability to take on projects of all sizes and types. Our approach to all projects is strategic and organized, which is the main reason why our projects progress seamlessly towards successful completion.

Our Process

Professional Project Initiation

At the initiation stage, our professional project managers will conduct a survey about your project, which will include site analysis, cost and time estimation, and general project requirements study in order to initiate a contract scope.

We will assist you in finding the best ways and solutions to bring your project to a high efficiency status by providing you with knowledge and experience that we proudly gained during our many years in the commercial construction industry.

Organizing and Preparing

Upon completion of the initiation stage, Kastone professionals will then start organizing and preparing for construction.

At this stage, all project details are taken into account including budgets, schedules, permits, project objectives, etc. When all details are put together, a management plan will then be issued for review by client and all other stakeholders involved in the project )(design team, sub-trades, government and other authorities, etc.)

Construction will start once the management plan is ready and approved.

Carrying Out the Work

The actual construction stage is highly dependent on the previous stages. We tend to follow all plans and schedules that are put in place at the earlier stages in detail in order to guarantee success.

You can depend on Kastone for all your construction and multi-trade project needs as we only work with the finest skilled crews and sub-trades to cover all 16 divisions of modern construction.

Our project control team will make sure that quality, cost, risk, and time are all being met and are to the expectations of our clients.

Closing the Project

We will not stop working until you are fully satisfied with what we’ve done. Period.

Towards the end of every project, we will conduct a walk-through with our clients to make sure that the scope of work is fulfilled, and that there are no deficiencies with our complete product. 

Closing a project involves a detailed review of all aspects of the project in order to ensure product quality and client satisfaction. Documents are archived for future reference.

Tenant Fit-ups

Tenant fit-up projects are always unique and each has its own character. We provide a planned approach designed to deliver the project in the most efficient process possible by  studying all aspects of the work and the conditions prior to tendering and construction stages.
