Expertise
Preconstruction
Oltmans has achieved a significant amount of our success by providing the highest level of preconstruction services available. Our dedicated estimating team’s experience and in-depth industry knowledge, along with the firm’s well-established relationships with the design and subcontractor community, bring the necessary value and foresight to each project ensuring that each product we produce is the best available on the market. We offer a diverse team of estimators on our projects, each with expertise in budgeting, preconstruction, construction, and concrete estimating. We understand that cost control is one of the most crucial areas of responsibility during the estimating process and have well-established systems and procedures to address this.
Critical Preconstruction Services
Subcontractor Prequalification & Selection
All subcontractors undergo a stringent prequalification process through our cross-platform project management tool, CMiC. They are vetted on the following benchmarks: safety, financial security, current work capacity, and previous work history. When subcontractors fail to meet our standards, they are flagged in the system and proactive conversations are started to qualify them for continued use on our projects. This mitigates project risk and gives our clients important information to make their selection.
Building Information Modeling (BIM) & Clash Detection
Oltmans Construction Co. utilizes Revit as a Building Information Modeling (BIM) platform, to ensure that all data and decisions are integrated into a common database. This also allows for enhanced clash detection and periodic 3D views of how the environment is developing, all before construction on the project begins. We have managed this program in a variety ways, from outsourcing to providing in
house services.
Long Lead Item Procurement & Material Escalation
Taking into consideration the current volatility in the commodities market, it has been extremely important to lock in procurement early. Doing this requires our clients and subcontractors to provide and honor expiration dates. Oltmans has a proven record of diligently working with the team to identify which commodities should be bought out as soon as possible, in an effort to protect the pricing and delivery dates provided during bid time.
Value Engineering
Oltmans regularly works with the Owner and subcontractor/vendor base to provide cost-effective alternatives as required. We evaluate value engineering and alternate options based on the cost-effectiveness of what is being proposed, its constructability, as well as its overall performance capability.
Design-Assist
We do our due diligence to conduct rigorous internal reviews with subcontractor input at each stage of the project, from schematic design (SD) to design development (DD) to final construction documents (CDs) delivery. As a transparent team member, we actively review the project for potential cost or schedule savings with the end goal of producing accurate guaranteed maximum price (GMAX) contracts. These services are a part of our delivery process to ensure that our owners get the best value in today’s marketplace.
Oltmans undergoes the same comprehensive design-assist services for every project regardless of contract structure including:
- Conceptual budgeting
- Feasibility and constructability studies and design reviews
- Solicitation of applicable subcontractor input
- Realistic scheduling and logistics
- Material procurement, escalation tracking, and schedule projections
- Labor requirements, including union, prevailing wage, local hire programs, or diversity, equity, and inclusion (DEI) tracking
