Contractual Relationships

Helmkamp Construction Company is a full service general contractor with construction management and design build experience. We have been serving the St. Louis and Metro East construction markets since 1938. Our focus is working for customers who buy construction yearly in a repeat professional manner mainly in the private building, industrial, and institutional industry. We have the ability to self perform excavations, concrete foundations and slabs, structural steel, rough and finish carpentry, labs, millwright equipment installations, and laser alignment/precision leveling tasks.

We work with the owner to determine the best contract for the project, and serve as the prime contractor or construction manager on conventional, design/build, and/or fast track projects under a negotiated or competitive bid basis.


Partnering agreements have proven to be extremely beneficial in that all books are open to our clients. The open management system and the ability to provide a team with a specific type of experience allows a much tighter control on project budgets, schedules, and overall construction quality. We are very proud of our repeat business status with our customers, and the trusting partnerships and alliances, which include maintenance and capital work with companies such as: BJC Healthcare, Clean Coal Solutions, Monsanto, OSF St. Anthony’s, Phillips 66, Principia, and Washington University.

Preconstruction Services

From concept to beginning construction, several customers have contracted with us for these types of services. We offer budget estimates as well as constructability and schedule reviews. We have performed these services while working with the owners architect/engineer, or recommending an architect/engineer after the parameters have been established.

Construction Management

Helmkamp Construction Company has served our clients needs by working with project teams in the roll of construction managers. Helmkamp is staffed with personnel experienced in all phases of project development and can successfully manage projects from conception through design development, pre-construction, construction, project completion and project documentation.


Over the years we have developed excellent working relations with architectural firms. This allows us to select or recommend the best architect or engineer for each particular client’s needs. We recognize our strength as a general contractor lies in our construction skills. Utilizing the services of an architectural or engineering firm to perform the design phase, we are able to secure all of the expertise and resources of the design professional while retaining the advantages of the design/build contract for our client.
