Building Additions

We conduct detailed assessments of existing construction including concrete specifications, finishes, and structural details. We create mock-ups to match color, texture, and elevation. Our crews use precision forming and finishing techniques to ensure seamless integration. Quality control includes side-by-side comparisons and adjustment of mixes to achieve perfect matching. We provide samples for owner approval before full construction.

Structural integrity requires evaluating existing foundation capacity and designing proper connections between old and new construction. We assess load transfer, differential settlement potential, and structural continuity. Geotechnical reports guide foundation design for Mansfield's clay soils. Expansion joints and proper reinforcement prevent cracking. We coordinate with structural engineers for comprehensive analysis.

Yes, we specialize in occupied building additions using phased construction and protective measures. This includes temporary barriers, dust control, and work scheduling around business hours. We maintain safe access routes and coordinate with building occupants. Some additions may require temporary relocation of operations for specific areas. Our crews work efficiently to minimize disruption while ensuring safety.

Building additions require permits from the City of Mansfield Building Department, including site plan approvals and structural reviews. Zoning permits may be needed if the addition changes building use. Additional permits cover electrical, plumbing, and mechanical work. We handle all permitting and schedule inspections. Environmental permits may be required for stormwater management.

Addition duration varies by size and complexity, typically 8-16 weeks for concrete work. A 2,000 square foot office addition might take 10-12 weeks including foundation work, concrete placement, and finishing. Phased construction allows partial occupancy. Weather conditions and permit processing affect timelines. We provide detailed schedules with milestone dates and contingency planning.

Foundation requirements depend on existing capacity and new loads. We may extend footings, add piers, or reinforce foundations. Soil conditions in Mansfield require geotechnical evaluation to prevent settlement. New foundations must match existing construction for structural continuity. We ensure proper load transfer and prevent differential movement between old and new construction.

Addition costs range from $100-$250 per square foot depending on complexity and specifications. A basic 1,500 square foot addition might cost $150-$200 per square foot including concrete work. Factors include foundation requirements, phasing needs, finish matching, and site conditions. We provide detailed estimates after building assessment and can suggest cost optimization options.

Connection challenges include matching elevations, preventing cracks at transition points, and ensuring watertight seals. Temperature differences between old and new concrete can cause movement. We use proper joint design, reinforcement, and expansion provisions. Mansfield's clay soils can cause differential settlement if not addressed. Our experience ensures seamless connections that maintain structural integrity.

North Texas weather requires flexible scheduling and protective measures. We use weather protection systems for exposed work and monitor forecasts for optimal concrete placement. Summer heat demands special curing procedures, while winter requires freeze protection. Our crews work efficiently during favorable conditions and have contingency plans for weather delays. Indoor work continues regardless of outdoor conditions.

We provide comprehensive documentation including as-built drawings, concrete test results, material specifications, and warranty information. This includes structural details, utility locations, and maintenance recommendations. Documentation supports future renovations and ensures building code compliance. We maintain records for the building owner's permanent files and provide digital copies for easy reference.
