About Self-Perform Group

Control from the Ground Up

Roncelli’s Self-Perform Group strengthens how we plan, coordinate, and execute critical scopes of work. With experienced crews, dedicated equipment, and direct field leadership, we manage key scopes such as structural concrete, site work, solar installation, and supplemental field services with greater control over safety, schedule, quality, and cost.

For our clients, that means fewer handoffs, faster response times, stronger accountability, and a more coordinated construction experience from early planning through field execution. It also gives our teams greater visibility into schedule-sensitive scopes, helping us identify issues earlier and keep critical work moving with fewer disruptions.

Concrete services delivered with precision

What We Self-Perform

Roncelli self-performs select construction scopes that benefit most from direct field oversight, schedule control, and coordinated execution. By integrating these capabilities into the project delivery process, we reduce handoffs, improve sequencing, and maintain consistent safety and quality standards across critical phases of construction.

Structural & Industrial Concrete

Concrete is the core of our self-perform operations. Roncelli delivers foundations, footings, structural systems, and large-scale flatwork that support advanced manufacturing, healthcare, institutional, and energy facilities.

Our teams are experienced in high-load industrial environments where structural precision, sequencing, and coordination are critical to downstream trades and equipment installation.

Core services we provide:

Spread footings and deep foundations

Structural walls, columns, and cores

Equipment foundations and machine pads

Interior slabs and reinforced flatwork

Exterior slab-on-grade systems

Large-format industrial floor systems

Civil & Site Work

Roncelli’s civil and site work capabilities support early site development, infrastructure coordination, and critical path schedule control. By aligning site work with our self-perform concrete operations, we improve coordination, protect schedule reliability, and reduce handoff delays in the field.

Integrated civil operations allow us to manage structural and site scopes under unified field leadership, improving schedule reliability and cost control.

Core services we provide:

Excavation and grading

Site concrete and utility structures

Pile caps and civil foundations

Exterior infrastructure support

Earthwork preparation and backfill

Solar Mechanical Installation

For utility-scale and commercial solar projects, Roncelli provides self-perform installation services supporting structural and mechanical systems.

By aligning structural and mechanical scopes within a single workforce, we streamline field sequencing and reduce handoff delays across large solar developments.

Core services we provide:

Pile installation

Racking system installation

Solar module installation

Balance-of-system support

Site coordination and sequencing

Two construction workers in hard hats and safety vests work inside a partially built structure with cinder block walls; one worker uses a concrete drill on a wall while standing on a metal-reinforced ground, and the other is handling a tool near a doorway where fresh concrete has been poured.

Supplemental Field Services

When project demands require additional control, flexibility, or speed, Roncelli provides select supplemental scopes to maintain schedule continuity and field coordination. These services are deployed strategically to support overall project performance, not as stand-alone specialty trades.

Core services we provide:

Selective demolition

Rough carpentry and temporary structures

Site modifications and retrofit support

Field coordination and supplemental labor

Built Into the Way We Deliver

Roncelli’s self-perform capabilities are built into the project delivery process from planning through execution. By involving our field teams early, we support constructability, improve sequencing, and maintain stronger control over critical scopes of work. For clients, this means greater schedule certainty, clearer coordination, and consistent safety and quality standards across the field.

Integrated through:

Preconstruction planning and constructability input
Critical path coordination during construction execution
Consistent safety, quality, and communication standards
Field leadership aligned with the full project team
