Integrated Exterior Renovation: Landscape, Façade, and Drainage Under One Contract

Walk through any commercial property in the Cincinnati corridor that's gone through a major exterior renovation in the last decade, and you'll usually find the same pattern. The façade was bid to one contractor. The drainage retrofit was bid to a civil-adjacent site contractor. The parking lot resurfacing went to a paving company. The retaining walls and hardscape went to a landscape contractor. The plantings were a fifth scope, the irrigation a sixth, and the signage and lighting site work a seventh. Each scope was bid separately, each contract was negotiated independently, and the property manager — usually with one or two project managers spread across a portfolio — was the de facto general contractor coordinating seven trades through a project that should have been one.

This is the standard model for commercial exterior renovation. It's also the most expensive way to deliver the work. The fragmentation tax — paid in trade coordination time, mobilization redundancy, schedule slip, and accountability gaps — is real, measurable, and almost universally underestimated. RCG's Site Works division was structured specifically to eliminate that fragmentation tax by pulling commercial landscape installation, drainage, hardscape, and adjacent site scopes under the same GC contract that handles the building's interior renovation, façade work, and ADA improvements.

This guide makes the case for integrated exterior renovation — bundling the landscape, façade, drainage, and parking scope under one contract — and explains where the savings actually come from.

The fragmentation tax: where the costs hide

Fragmenting an exterior renovation across multiple trade contracts adds cost in five places that aren't always visible on the bid sheets:

Trade coordination overhead. When seven trades work on one site sequentially, somebody has to coordinate them. On a fragmented project, that "somebody" is the property manager or owner's representative. On an integrated project, that's the GC's project manager — included in the GC's overhead, baked into one contract. Property managers who track their actual coordination time on multi-trade exterior projects routinely find they've spent 100–300 hours of internal time managing what should have been single-contract scope. At a fully loaded labor rate of $75–$150/hour, that's $7,500–$45,000 of hidden cost.

Mobilization redundancy. Each trade contractor mobilizes equipment, sets up site logistics, establishes access, and demobilizes when their scope finishes. Seven trades mean seven mobilizations. An integrated GC contract with self-performed Site Works mobilizes once and handles the multiple scopes through a single site logistics plan. The mobilization savings on a typical $250,000 mid-size commercial renovation runs $15,000–$35,000.

Schedule float and dependency slip. Fragmented projects accumulate schedule slip at every trade-to-trade handoff. Drainage finishes late, paver install can't start. Façade scaffolding stays up longer than planned, landscape can't access the building edge. Sod gets installed before irrigation is commissioned, and sod fails. Each handoff is a potential delay point, and each delay compounds. Integrated GC scope manages the dependencies internally — paver install schedules around drainage completion because the same project manager is running both crews.

Accountability gaps. When something goes wrong six months after substantial completion — water pooling at a building threshold, paver settlement at a drive aisle, a retaining wall showing movement — the fragmented project model creates immediate finger-pointing. The drainage contractor blames the paver contractor's compaction. The paver contractor blames the drainage contractor's invert. The landscape contractor blames both. The property manager spends three months arbitrating. The integrated GC contract closes the gap: one contract, one accountable party, one warranty.

Insurance and bonding redundancy. Each trade contractor brings their own GL coverage, their own workers' comp, their own auto coverage, often their own bonds. Each set has to be verified, certificates collected, additional-insured endorsements processed. The administrative overhead is real. One GC contract consolidates the requirements.

In aggregate, the fragmentation tax on a typical mid-size commercial exterior renovation ($250K–$750K total scope) runs 10–20% of total project cost — meaning a fragmented $500K project that integrates would have run roughly $400K–$450K with the same outcome.

What integration looks like in practice

The integrated exterior renovation model bundles five scope categories under one GC contract:

Façade and exterior cladding. Wall systems, ACM panels, EIFS, masonry, storefront systems, and exterior architectural elements. RCG's existing exterior cladding service anchors this scope.

Site drainage and stormwater. French drains, channel drains, catch basins, detention retrofits, bioretention, PICP, and underground systems. See our commercial drainage service page for scope.

Hardscape and paving. Paver plazas, walkways, parking lot pavers, retaining walls, and other site work. Our paver installation and retaining wall services.

Landscape installation. Sod, plantings, irrigation install, mulch, and bed prep — install only, no maintenance. Our sod, plantings, and irrigation services.

Site grading and erosion control. Earthwork, fine grading, and SWPPP-compliant erosion control during construction. See site grading and erosion control.

A single GC contract delivers all five through a unified project schedule, single mobilization, integrated subcontractor management, and one warranty package at substantial completion.

Where it doesn't work — and where it does

Integration isn't always the right model. There are scenarios where fragmenting scope makes sense:

• Major civil scope (large-scale grading, deep utility work, significant earthmoving) usually goes to dedicated civil contractors regardless of GC integration. RCG's Site Works division handles typical commercial earthwork; we don't compete with major civil firms on civil-scale work.
• Highly specialized façade systems (curtain wall, complex glazing, specific architectural systems) sometimes warrant direct trade contracts with specialty subcontractors.
• Very small scopes (single drainage retrofit, isolated wall section) don't need GC integration overhead.

Integration shines for the mid-tier commercial renovation: $100K–$1M total exterior scope, multiple trade categories, occupied or partially occupied facility, and a property owner who values single-point accountability over the (often illusory) savings from fragmenting bids.

Why this is harder for landscape-only contractors to deliver

The integrated exterior renovation model requires a contractor who can actually deliver the building scope, not just the site scope. Most landscape companies — even commercial-focused ones like Klausing Group in Lexington, Grunder Landscaping in Dayton, or Oberson's in Cincinnati — don't do façade work, don't do tenant improvement, don't do healthcare renovation, and don't carry the GC license, insurance capacity, or project management depth to manage building scope alongside site scope.

Conversely, most commercial general contractors don't self-perform commercial landscape installation. Messer, HGC, Walsh, and Brown + Kubican will execute building renovation but they sub out the landscape, drainage, and hardscape scope to landscape companies — recreating the fragmentation under one contract.

The integrated exterior renovation model requires a contractor who self-performs both. RCG's structure — commercial GC scope plus a self-performing Site Works division — was built specifically for this delivery model. It's the differentiator the corridor doesn't have a clean substitute for.

What this means for facility managers planning capital projects

Three practical takeaways:

One: when you're scoping an exterior renovation, get an integrated bid alongside the fragmented bid. Most property managers default to fragmented bidding because that's how they've always bid this work. Asking RCG (or another integrated provider) to bid the full scope as one contract gives you a real comparison — and the cost difference is usually meaningful enough to change the approach.

Two: budget for fragmentation tax in the fragmented model. If you're going to bid this fragmented, put a coordination line item on your project budget — typically 5–10% of total project cost — to fund either an owner's representative or sufficient internal project management capacity. Failing to budget for coordination is what creates the schedule slip and accountability gaps that hurt the project.

Three: align the warranty structures. Whether you bid integrated or fragmented, make sure the warranty structures across scopes don't create gaps. The integrated GC contract automatically aligns warranties; the fragmented model requires deliberate contract-by-contract alignment. Pay close attention to where one contractor's scope meets another's — that's where warranty gaps and finger-pointing happen.
