5 Preconstruction Steps That Prevent Costly Delays
The preconstruction steps that prevent costly delays are the ones that catch problems while they’re still on paper, before they turn into a redesign, a rejected permit or a change order on site. Five steps do most of that work:
- Checking feasibility and zoning before you commit to a site
- Setting a clear program and budget early
- Coordinating the design in a 3D model
- Planning permits and approvals from the start
- Getting builder input before drawings are locked
Each one costs far less to do well during planning than to fix once crews are working. This list is for multifamily developers, builders and owners preparing for a new build or major renovation, especially if your pro forma can’t absorb months of slippage.
1. Check Feasibility and Zoning Before You Commit to a Site
A lot of delays trace back to a site that can’t support the plan. Zoning sets your density, height, setbacks, lot coverage and parking ratio, and those limits decide how many units you can build. If your target count needs a rezoning or variance, you’ll need entitlements, the approvals that give you the legal right to build a particular project, and those can add months. Site conditions matter too, since utility capacity, stormwater rules, soils and access can all change what fits.
Get this checked before you close on the land or pay for full design. Ask for a test fit, a quick layout showing how many units and parking spaces the site can hold under current zoning. The WisdomTree Group provides preconstruction support for multifamily projects that begins with this kind of site analysis, zoning review and test fitting, so you know what the site supports before design money is spent. If you’re building by right on a site type you’ve developed before, a lighter check may be enough.
2. Set a Clear Program and Budget Early
Your program is the written list of what the building must include: unit mix, unit sizes, amenities, parking and any commercial space. When it’s vague, the design keeps changing, and every change costs drawing time and pushes the schedule back. Pin it down early and tie each item to your pro forma, so you can see what a two-bedroom unit or a fitness room adds to rents and costs.
Then ask for estimates at each design phase, beginning with a conceptual budget and getting more detailed as drawings develop. Good preconstruction services price the design as it grows, so you catch a budget gap at schematic design instead of on bid day. Keep the program document current, too. Update it whenever a decision changes, and share it with everyone on the team.
3. Coordinate the Design in a 3D Model Before Drawings Are Final
Building Information Modeling, or BIM, is a coordinated 3D model that brings the architectural, structural and mechanical, electrical and plumbing (MEP) systems into one place. Its biggest scheduling benefit is clash detection, which flags conflicts such as:
- A duct running through a structural beam
- A drain line passing through a fire-rated wall
- Ceiling heights being too low for the ductwork above
Each clash fixed in the model means one fewer request for information (RFI), the formal question a contractor sends when drawings don’t work in the field. It also means one fewer crew standing idle while that question gets answered.
Ask your architect whether every discipline will be modeled and checked before the construction documents are issued. Those are the final drawings and specifications used for permits and bids, so errors in them carry straight into the field. A small renovation with limited systems work may not need full coordination, but most new apartment buildings will.
4. Plan Permits and Approvals From the Start
Permit timelines are one of the easiest delays to underestimate. List every approval your project needs, including zoning relief, design review, building permits, and utility sign-offs, then build your schedule around how long each review typically takes in your jurisdiction. Some reviews must happen in order, so a late zoning decision can hold up everything behind it.
Philadelphia shows how layered this can get. Zoning and building permits go through the Department of Licenses and Inspections, variances go to the Zoning Board of Adjustment, and larger projects may need Civic Design Review with the City Planning Commission. If you’re searching for preconstruction services Philadelphia developers have used successfully, ask how recently each team has taken a project through those boards and how they prepared for the hearings. Check current requirements on the city’s official websites, since rules and thresholds change.
5. Get Builder Input Before Drawings Are Locked
A design can look complete and still be hard or costly to build. Bringing a contractor in during design development, the phase where systems and materials are worked out, lets them review constructability, check pricing and suggest a sequence of work. That catches problems early, such as long-lead materials, awkward details, or assemblies that local crews don’t know well.
Builder input also cuts down on last-minute value engineering. Value engineering means finding a less expensive way to deliver the same function, and when it happens after bids come in over budget, it forces redrawing and sometimes resubmitting permits. Schedule at least one formal constructability review before construction documents are finished. If you’re repeating a prototype with a builder who already knows it, a shorter review may cover it.
Put a Preconstruction Plan in Place Before You Commit
Gather what you know about your site, its zoning, your target unit count and your budget. Then ask any architect you’re considering how they’d handle each of these five steps on your project, who would be involved, and when.
Clear answers now will tell you how well protected your schedule is before work starts on site.
