Mistake #1: Inadequate information on bid documents (construction drawings and specifications). —
This is the most common complaint I hear from contractors. While there is no single standard for the proper amount of information that should be included on bid drawings for every project, an architect should provide enough information for bidders to compile a reasonably accurate project price. Because the architect has mentally “built” the project while doing its design, he should be aware of the parts of the work that will be more challenging to construct and that require more detail to price correctly.
The judgment about how much information to provide on drawings and in specifications is influenced by the amount of the architectural fee the owner has agreed to pay and by the level of professional thoroughness the architect brings to his work. In most cases, a homeowner should not expect the second factor to trump the first. An experienced architect sows the seeds for an effective bid process by requesting an adequate fee to produce good bid documents. A homeowner acknowledges the importance of good documents for pricing the work accurately by agreeing to pay that fee.
This relationship can be thrown off balance in times of economic uncertainty. A homeowner may feel pressure to minimize project costs by lowering the fee paid to the architect (for work that is, despite its importance, largely intangible), who may take on work for a fee that doesn’t support doing it thoroughly. Thus, both are responsible for unfairly pushing the quality/cost mismatch down the road for the contractor to reconcile.
Regardless of the reason, the impact of incomplete bid drawings and specifications can be felt long after the bid process is over because they typically lead to a much higher number of reasonable change-order requests from the builder that a contractually bound homeowner, with few practical options, must accept. In my experience, the final cost of a project bid with inadequate drawing and specification information will commonly exceed the original bid price by 20% to 40%—not good for the homeowner at any time, and certainly not good for one with a limited budget.
Mistake #2: An excessive number of bidders. —
As noted earlier, developing a thorough bid requires a big investment. Small renovation projects are typically done by small-size general contractors with limited cash reserves. These builders will not take the time required to produce a thorough bid for a project they have little chance of getting because the number of bidders is high. Many think that no more than three contractors should be asked to bid on small projects.
Occasionally, I suggest that homeowners get four bids because of the increased confidence I have that a grouping of three similar prices indicates there may be a problem with a fourth bid that comes in either unusually high or low. A very low bid should be questioned rather than seized upon as an opportunity to save money.
Mistake #3: Bidders who are not comparable. —
Homeowners and inexperienced architects may include a company in a group of bidders that has a definite operating-cost advantage over its competitors, such as a smaller, less-well-known firm without an extensive record of project work. They may believe that this company’s bid will be a useful reference for what the project “should” cost, and they may even try to use this figure to leverage a lower price from the most desired builder, presumably via charging a lower markup on the project’s direct costs.
This idea may appear to be a clever negotiating tactic. But if the preferred builder elects to retain its markup and lower its bid price by substituting more expeditious, less prudent building methods than those it had included in its original price, the likelihood of future building problems will rise. It also should be clear that any bidder asked to spend time and money to develop a thoughtful bid is treated unfairly if an owner and an architect know that they will not select this bidder to do the work, regardless of its price, but are simply seeking another cost figure for comparison.
Remodeling and construction are service businesses, not commodity businesses. In a slow economy especially, homeowners and architects are well advised to remember this fact when selecting contractors. Although bidding can provide a homeowner with a low initial price to do a project, it is likely not a good way to select a contractor to get high construction quality. To do this, it is best to choose the most desirable contractor based on a perception of his competence and fairness; his track record of building well-designed projects; and insightful comments received both from customers and architects with whom he has worked. After a contractor has been selected and has carefully reviewed and commented on the information in the drawings and specifications, then it’s time for him and the homeowner to negotiate a detailed price for the work.
