When a corporate client needs to expand their building, the first question is not which design to choose, but which service format best suits their actual situation. Not all projects justify a full architectural contract from day one. Some only require a preliminary design with CAD drawings to assess feasibility. Others need a closed budget for an expansion with prefabricated modules, where the scope is defined before the first meeting.
The decision depends on three specific factors: the client's degree of uncertainty, the available timeline, and the budget allocated to the design phase. A developer who already has the land and the program of needs may opt for an integrated design and construction service, where the company takes on both the project and its execution. In contrast, a company still evaluating growth options benefits more from a pre-feasibility study, with modular schemes and cost estimates per square meter.
In practice, the most useful format is often the one that separates the stages without losing continuity. For example, a preliminary design contract that includes three structural addition alternatives, with CAD drawings and an indicative schedule. If the client decides to move forward, that same preliminary design becomes the basis for the executive project, without starting from scratch. This avoids paying twice for the same work and reduces coordination times with the construction company.
Another point that clients value is the possibility of hiring only technical consulting to review an existing design. Not all expansions require a new project; sometimes the client already has drawings from a previous study and needs a structural verification or a regulatory update. In those cases, offering a review service by the hour or as a fixed package is more efficient than forcing a full contract.
The important thing is that the chosen format reflects the client's actual situation, not a service template. Therefore, before signing any agreement, it is advisable to have a frank conversation about what is needed and what is not. A good corporate expansion service is not the one that promises the most, but the one that fits the specific problem to be solved.
Before requesting a quote for a modular addition, it is advisable to have the building's current plans, load requirements, and intended uses clear. This guide details the documentation a developer should gather, typical prefabrication and assembly timelines, and the key questions addressed in the first technical meeting. The goal is to make the initial consultation productive and avoid rework.
Not all modular expansions require the same level of engineering. This article compares three modalities: turnkey addition, panel supply with supervised assembly, and structural consulting for traditional construction. Real cases of offices in Buenos Aires and Córdoba are analyzed, with relative costs and execution times. The decision depends on the profile of the existing building and the developer's schedule.
From the load-bearing capacity of the existing slab to compatibility with central HVAC systems, developers often have very specific doubts before signing a contract. This article compiles the most common queries received in the last twelve months, with technical answers based on Argentine regulations and examples of previous projects. Useful reading for anyone evaluating a first modular expansion.
