Program + Project Management
The quality of our built environment is dependent on many factors. While design excellence is clearly one, the management of the program and the delivery process is responsible for success measured in terms of budgets, schedules and programs. We recognize that the program development and building process has become increasingly complex, particularly with regard to projects of scale which have multiple constituencies and requirements. Responding to these needs and using a long history of success with complex building and development programs, we have developed simple, flexible, yet comprehensive processes to meet the needs of our clients and their programs. We offer services in the following five categories: Program Development Services, Management Services, Planning Services, Facilities Services, and Project Audit and Review Services
Programming
Programming is the basic foundation of any design process that starts with master planning. How else does one know how to evaluate the scope of the project, assess its expectations, or measure its degree of success at the master planning, design phase and final product levels? L-DS starts from a simple framework of “issue identification” that allows the programmer / planner / architect to guide the development of the program, whether the project be modest or one of significant scale and complexity.
Planning + Urban Design

No where is there a need to anticipate change greater than in planning + urban design. Most projects of this nature are carried out over 10 to 20-year periods and involve the phased development of large land areas. We assist our clients with project feasibility and financing methods, strategic planning, master planning, urban design and project management. Our experience in managing the public/private coordination process ensures the successful implementation of complex projects for national, regional, and local governments, as well as some of the most prestigious corporate developers. The firm has won several awards for its work in architecture, planning, urban design, design guidelines, and design management and implementation.

Architecture + Interiors
L-DS provides architectural design services for commercial, institutional, industrial, and mixed-use projects including individual buildings or multi-building campuses. Good design requires strong analytical skills and creative design, backed by an equally strong management process. We emphasize all three elements as a way to achieve a high level of functional and aesthetic quality within a client’s budget and schedule of objectives. Our services are comprehensive, ranging from project feasibility, programming, site planning, interior design, architectural design, construction documentation, and administration. This enables us to serve our clients from the earliest stage of their projects through occupancy.
Development Advisory
In addition to traditional architectural services, L-DS offers development advisory services to its clients on the overall development of a project – strategic, financial, sustainable and functionality. In today’s world of high costs, it is most beneficial to decide upfront if your project will provide you the best return on your investment; if the design and planning efforts meet your needs not only today but tomorrow and the next; and if your project has been managed and implemented to ensure you every effort has been made to provide you an efficient, environmentally-sensitive, and sustainable facility. A good design is just that – a good design – addressing FUNCTION, EMOTION and GROWTH. On the other hand, a good design that has been strategically managed will incorporate CAPACITY, CHARACTER and SUSTAINABILITY.
Visualization

The key to success that underlines all our services is the ability to communicate visually. L-DS prides itself for being at the cutting edge of technology. We communicate ideas in a clear, legible, and interactive fashion with the use of integrated CAD, 3D, graphic, animation, and web design software.
