Opinion
Plaintiff Warner Construction Corporation brings suit against the City of Los Angeles for breach of warranty and fraudulent concealment in connection with a contract for construction of a retaining wall on Vista Del Mar, a street in the City of Los Angeles. A jury returned a verdict for plaintiff for $150,000. We hold that, since the interpretation of the crucial provisions turned on the credibility of expert testimony, the court did not err in submitting the constructon of the contract to the jury. We have also concluded that the evidence supports the jury’s finding of liability. Although certain letters of the city’s Board of Public Works, which contained statements tendered in negotiations for a compromise, should not have been admitted, their introduction did not cause prejudicial error. Plaintiff’s proven damages, however, reach at most $81,743.55; its failure to present evidence of lost profits renders damages over that sum speculative. The cause, therefore, must be reversed for a new trial on the issue of damages.
Vista Del Mar, a street in the City of Los Angeles, runs parallel to the waterfront along the crest of a hill. The hill is composed of sand and sandstone of varying but low cohesiveness. In 1964 the city requested bids for construction of a retaining wall, referred to as a sidehill bridge, to retard erosion which was undermining Vista Del Mar. In support of the retaining wall, there would be 29 soldier beams, reinforced concrete pillars of 24 to 30 inches in diameter and 18 to 34 feet in legth. Twenty-nine anchor caissons (reinforced concrete pilings) were to be sunk on the other side of Vista Del Mar, and joined to the soldier beams by 2-inch steel rods running under the roadway. *290 As the low bidder at $81,000, plaintiff obtained the award of the contract. The contract provided for amendment by “change orders” issued by the city at the contractor’s request. Five change orders were issued, increasing the contract price to $83,416.53.
During construction, caving occurred in unsupported holes. Plaintiff attempted to drive steel casings into the sand to support the walls of the holes, but due to the instability of the sand the jarring threatened the collapse of the entire work area. Plaintiff then requested a change order to permit drilling with rotary mud, 1 and a concomitant increase in price. The city refused, maintaining that the plans required only that holes be drilled, leaving the drilling method to the contractor’s discretion, and thus that no change order was needed. After extended but unsuccessful negotiations, plaintiff resumed construction using rotary mud without a change order, and completed the project.
Plaintiff’s suit asserts four causes of action. The first is for the balance of $4,725 plus interest due on the contract; defendant admits this debt. The second cause of action claims damages of $2,716.39 for a five-day delay in construction pending a change order increasing the depth of the wall by 4 feet. This cause of action does not relate in any way to the issues of warranty and concealment, and defendant’s briefs on appeal do not discuss it.
This appeal deals solely with plaintiff’s third and fourth causes of action, which allege respectively breach of contract and fraudulent concealment of material facts; plaintiff claims damages for the increased cost of construction resulting from the use of rotary mud, for loss of profits, for loss of business, and for loss of an advantageous competitive position in the industry.
Plaintiff bases its third cause of action on Standard Specification No. 158, paragraph 2-8, which provides that if the contractor encounters subsurface conditions materially different from those shown on the plans, which it could not reasonably be expected to ascertain in advance, a change order will issue to provide for any increase in cost resulting from the unexpected conditions. Plaintiff contends that the plans impliedly excluded use of rotary mud, leading it to believe soil conditions permitted casting without rotary mud; it claims a contractual right to a change order compensating for the increased cost of using rotary mud.
Plaintiff’s fourth cause of action, for fraudulent concealment, asserts *291 that the city did not disclose that cave-ins occurred in both test holes drilled by the city, forcing the city to change its drilling methods and to abandon the holes before reaching the planned depth of 50 feet. Plaintiff also claims that the city concealed information that two ancient landslides occurred at the construction site.
1. The issue of liability
We consider the issue of liability in three parts: (a) the logs of the test holes; (b) General Notes 7 and 8; and (c) the nondisclosures.
(a) The logs of the test holes
The plans and specifications included the logs of two test holes. The logs show that the city drilled two test holes on the site, which passed through various layers of sand. Undisputed evidence, however, demonstrated that the log of test hole No. 1 erroneously reported the soil to a depth of 14 feet as “coarse sand with clay binder” although the material actually discovered was “coarse sand with minute binder.” Likewise, the log of test hole No. 2 listed 26 to 35 feet as “sand with clay binder” although the material actually encountered at that depth was “sand with minute binder.” Mr. Maurseth, a soil mechanics engineer, testified that “clay binder” meant, in the trade, a sufficient amount of clay to cause the sand particles to adhere cohesively; “minute binder” meant the binding material is present in such minute quantities that it is inadequate to stabilize the sand. Being less cohesive, “sand with minute binder” is much more likely to cave in.
We do not accept defendant’s contention that the trial court erred in submitting the interpretation of the logs to the jury. Although defendant urges that under
Parsons
v.
Bristol Development Co.
(1965)
Attached to the test-hole logs was a caveat: “The test-hole information on these plans shows conditions found only at the date and location indicated. Bidders are cautioned that the city in no way warrants that such information is representative of conditions at any other location, *292 or at any other time. Groundwater levels, particularly, are subject to change.”
Although defendant contends that this note effectively disclaims any warranty, we find, on closer examination, that the warranty and the disclaimer pass each other without collision. The warranty describes the subsurface conditions at the test holes, but says nothing about conditions elsewhere on the site. The disclaimer states that “the test-hole information . . . shows conditions found only at the date and location indicated,” and cautions bidders that the city does not warrant that the data is representative of other locations, but it in no way disclaims the accuracy of the test-hole logs.
2
Reading the two together, we conclude that the bidder takes the risk in making deductions from accurate test data, but the city retains responsibility for any inaccuracy in the data. (See
Wunderlich
v.
State of California
(1967)
Whether the misrepresentation of “clay binder” for “minute binder” was a material misrepresentation, whether plaintiff relied on it, and whether that reliance was reasonable, all present disputed questions *293 of fact properly submitted to the jury. The jury’s verdict impliedly resolved these issues in plaintiff’s favor.
(b) General Notes 7 and 8
The plans and specifications contained 16 “General Notes.” Note 7 provides that “holes for the soldier beams and anchor caissons shall be made by boring and/or drilling.” Note 8 states: “soldier beams and anchor caissons shall be cast in place within unsupported holes, except that where, in the opinion of the engineer, the holes are subject to caving or sloughing, or are in any way unstable, the walls shall be temporarily supported by steel casings or shells. Before placing the steel casing or shells as much of the loose soil as is practical shall be removed from the holes.”
Defendant contends that the language of Notes 7 and 8 does not prohibit the use of rotary mud, but leaves the drilling technique entirely to the contractor’s discretion. The rotary mud technique, however, is an unusual and expensive method of drilling, and results in castings of . less strength than casting against virgin soil. 3 Plaintiff adduced substantial expert testimony, including not only plaintiff’s experts but also Mr. Reader, the city’s engineer in charge of designing the sidehill bridge, to the effect that the specifications of General Note 8 impliedly excluded the use of rotary mud and that a change order would be required to permit rotary mud drilling.

A
fraudulent concealment often composes the basis for an action in tort, but tort actions for misrepresentation against public agencies are barred
*294
by Government Code section 818.8.

Plaintiff retains, however, a cause of action in contract. “It is the general rule that by failing to impart its knowledge of difficulties to be encountered in a project, the owner will be liable for misrepresentation if the contractor is unable to perform according to the contract provisions.”
(City of Salinas
v.
Souza & McCue Construction Co.
(1967)
In transactions which do not involve fiduciary or confidential relations, a cause of action for non-disclosure of material facts may arise in at least three instances: (1) the defendant makes representations but does not disclose facts which materially qualify the facts disclosed, or which render his disclosure likely to mislead; 5 (2) the facts are known or accessible only to defendant, and defendant knows they are not known to or reasonably discoverable by the plaintiff; 6 (3) the defendant actively conceals discovery from the plaintiff. 7
All these instances are present in this case, or so the jury could find. The nondisclosure of the cave-ins and special drilling techniques used in drilling the test holes transformed the logs into misleading half-truths. *295 The facts concealed were exclusively available to defendant. Finally, plaintiff presented evidence of intentional concealment by the city. 8
2. Completion of Performance
The city argues that, since the contract did not expressly authorize use of rotary mud, plaintiff, in performing in that manner, attempted to force the city to reform the contract and to subvert the policy requirement of competitive bidding. It contends that modifications of a contract can only be awarded through competitive bidding
(Paterson
v.
Board of Trustees
(1958)
As the court in
Gogo
v.
Los Angeles etc. Flood Control Dist.
(1941)
Defendant stands on somewhat stronger ground when it alleges that, in view of the situation, plaintiff delayed too long before resuming work. Section 2-8 of the Standard Specifications, however, contemplates that the contractor will halt performance pending issuance of a change order, and the reasonableness of plaintiff’s delay and its resulting claim for damages raised questions for the jury.
*296 3. A dmission of Evidence
On February 23 and 24, 1965, plaintiff notified defendant of its unwillingness to continue work without a change order. On March 8 defendant sent plaintiff a report of the Board of Public Works stating that “consideration of alternate methods of constructing the project is not thought to be necessary,” and directing plaintiff to resume work.
On March 19 plaintiff sent another request, which suggested that rotary mud be used at an additional cost to the city of $12,000. The president of the Board of Public Works, Mr. Gill, sent plaintiff a letter on March 25 authorizing use of rotary mud and stating that the city would assume the additional cost. On March 29 the secretary to the board confirmed this communication, stating that the city engineer would issue an appropriate change order. In the meantime, however, plaintiff discovered that the additional work would cost not $12,000 as previously estimated, but $34,400, and it so notified the city. As a result of this communication the defendant did not issue the change order at $12,000; it rejected plaintiff’s $34,400 offer.
The trial court, over defendant’s objection, admitted into evidence the letter from Mr. Gill authorizing use of rotary mud and stating that the city would assume the additional cost, and the letter from the secretary of the board confirming the president’s letter. Plaintiff offered these exhibits generally, without specifying any basis for their admission. Defendant objected on several grounds, including Evidence Code section 1152, which provides in part: “Evidence that a person has, in compromise . . . , furnished or offered or promised to furnish money or any other thing, act, or service to another who has sustained or will sustain or claims that he has sustained or will sustain loss or damage, as well as any conduct or statements made in negotiation thereof, is inadmissible to prove his liability for the loss or damage or any part of it.”
We cannot accept plaintiff’s contention that the correspondence could properly have been admitted to show the contemporaneous and practical construction of the contract. We recognize, however, that the court could properly have admitted the evidence for the limited purpose of proving plaintiff’s bona fide and good faith efforts to reach an agreement so that work could be resumed. But the court imposed no such limitation, and we find no basis to hold that defendant waived the point. We finally conclude, however, that, despite the error in admission of the evidence, no prejudice to defendant resulted.
The principle of “practical construction” applies only to acts performed under the contract before any dispute has arisen. The “construction
*297
given the contract by the acts and conduct of the parties with knowledge of its terms,
before any controversy has arisen as to its meaning,
is entitled to great weight and will, when reasonable, be adopted and enforced by the court.” (Italics added.)
(Woodbine
v.
Van Horn
(1946)
Plaintiff argues that since the contract provides for its own modification by change orders, a dispute should not be said to arise until the parties have abandoned efforts to resolve the controversy within this contractual framework. Although the instant agreement does include an amendatory procedure, all contracts can be amended by consent of the parties; a compromise in a contract dispute, even if reached at the courthouse steps, will often take the form of a modification of the contract. We see no valid grounds for distinction between contracts which contemplate amendment and those which do not. 11 The purpose of section 1152, to promote candor in settlement negotiation (see Evid. Code, §1152, Law Revision Com. com.), applies equally in both instances.
We have stated that we believe that the correspondence between the parties could have been admitted to show that during the delay of March 1965 plaintiff,'in good faith and pursuant to the contractual procedure, had engaged in negotiations in the reasonable hope that an agreement could be reached and the work resumed.
12
Admission of proof of negotiations for this narrow purpose would not be likely to discourage negotiations; on the other hand, the exclusion of such evidence, after defendant has put in issue the reasonableness of plaintiff’s delay of performance,
*298
would arbitrarily limit its rebuttal. Plaintiff then argues that “if evidence is admissible for any .purpose, it must be received,even though it may be highly improper for another purpose”
(Inyo Chemical Co.
v.
City of Los Angeles
(1939)
In the instant situation, however, defendant’s opportunity to seek a limiting instruction did not constitute a sufficient remedy. (See
Adkins
v.
Brett
(1920)
Furthermore, by the time of the submission of the jury instructions, a significant part of the trial testimony had been devoted to a discussion of the meaning and import of these exhibits. At this point a request for a limiting instruction would have been doubly futile; not only had the court apparently rejected the contention of the defense that the letters were offers of compromise under section 1152, but so much testimony had pertained to the letters that the jury could not reasonably be expected to follow any such instruction.
We have concluded, however, that the error did not cause prejudice to defendant. Plaintiff’s third cause of action alleged that plaintiff was entitled to a change order to permit use of rotary mud; the exhibits in question are the most convincing evidence presented on this question and their admission was plainly prejudicial so far as this cause of action is concerned. 17 Plaintiff’s fourth cause of action, however, was *300 for fraudulent concealment, and the correspondence is immaterial to this cause of action. 18
Plaintiff’s evidence of error in the test-hole logs and of concealment of material data was largely undisputed and, as pointed out supra at pages 291-293, defendant’s disclaimers under such circumstances cannot stand. The only major issue of fact that remains is whether plaintiff relied on the city’s data. Plaintiff’s president testified that he did so; expert testimony showed that such reliance was reasonable. Defendant points out that plaintiff dug its own test-holes, but such holes were intended only to confirm surface conditions and did not go to a depth sufficient to disclose the subsurface conditions misrepresented or concealed by defendant. 19
We conclude that it is not reasonably probable that, absent the erroneous admission of the exhibits, defendant would have attained a more favorable result (see
People
v.
Watson
(1956)
4. Damages
Defendant asserts that the $150,000 damages awarded plaintiff includes compensation for speculative and unproven items of damages.
*301
Although plaintiff undoubtedly should recover the additional cost of construction attributable to the city’s misrepresentations, plus a reasonable profit on the additional work (see
City of Salinas
v.
Souza & McCue Construction Co., supra,
The above items of damage total $81,743.55, which, deducted from the verdict of $150,000, leaves a balance of $68,256.45. According to plaintiff, this sum would do no more than compensate it for further losses. Warner testified that plaintiff was compelled to bear the additional cost of construction out of its own resources. This loss of capital, according to Warner, forced a curtailment in construction operations and in research; the loss likewise led to a reduction of bonding capacity as well as the destruction of plaintiff’s former advantageous competitive position in the industry.
For an established firm such as Warner Construction Corporation, an award for lost profits could not be criticized as speculative. (See
Lucky Auto Supply
v.
Turner
(1966)
*302
In
Stott
V.
Johnston
(1951)
Plaintiff contends that defendant waived its right to object to the award. Plaintiff stresses the following points: defendant’s failure to demur to the allegations of damages in the complaint, defendant’s emphasis in its argument to the jury upon the issue of liability, its omission of any discussion of the amount of damages, and the absence of any objection to the instructions on damages. Defendant, however, has never conceded that plaintiff was entitled to damages in excess of the $4,725 owing on the contract; nor did the instructions compel or permit the jury to award speculative damages. Defendant’s tactical decision to emphasize the liability issue and minimize discussion of damages does not, in our opinion, amount to a waiver of defendant’s right to object on appeal to speculative damages.
5. Misconduct by Plaintiff’s Counsel
In arguing to the jury plaintiff’s counsel repeatedly referred to the city’s public works budget of $60,000,000 a year.

Defendant asserts that

these references constitute an impermissible appeal to base damages on the wealth of defendant and to take into account the relative poverty of plaintiff. (See
Love

During plaintiff’s argument to the jury defense counsel did not object or request that the jury be admonished; instead, he waited until the conclusion of the arguments and then moved for a mistrial. In

Notes
Rotary mud is a drilling fluid. Added to the hole during drilling, it coats the sides of the hole and through hydraulic pressure aids in supporting the walls and preventing cave-ins. A steel casing can then be added for further support; after the use of rotary mud the casing need not be driven into the sand but drops of its own weight.
Standard Specification No. 158, section 2-1, contains another disclaimer, which is not discussed by the parties on appeal. This disclaimer reads: “While it is believed that information obtained by the Engineer will be reasonably correct, the City does not warrant either the completeness or the accuracy of such information. It is the responsibility of the Contractor to ascertain the existence of such additional conditions affecting his cost of doing the work as may be disclosed by a reasonable examination of the site.”
In
E. H. Morrill Co.
v.
State of California
(1967)
The trial court in the instant case read the section 158 disclaimer to the jury,' but instructed them that “if a public agency makes a positive and material representation as to a condition presumably within the knowledge of the agency and upon which the plaintiff had a right to rely, the agency is deemed to have warranted such facts despite a general provision requiring an on-site inspection by the contractor.” In submitting the issue of the effect of the section 158 disclaimer to the jury, and its instructions to the jury, the trial court complied with our decision in Morrill, and the verdict must be taken as resolving that issue against defendant.
General Note 8 contemplated casting the concrete against virgin soil; steel casings, if utilized, were only to furnish “temporary” support and to be withdrawn before casting. If rotary mud were used, it would coat the sides of the hole and the concrete would be cast against a thin layer of rotary mud. The resulting structure has somewhat less strength since slight lateral movement is possible before the concrete meets the resistance of the soil.
Section 818.8 states that “[a] public entity is not liable for an injury caused by misrepresentation by an employee of the public entity, whether or not such misrepresentation be negligent or intentional.” Section 814 provides that nothing in the Tort Claims Act “affects liability based on contract.” Interpreting these provisions, we held in

Evidence of the negotiations might also be admissible to rebut defendant’s claim that plaintiff failed to mitigate damages (see supra, at p. 295); if defendant had raised any issue respecting plaintiff’s exhaustion of contractual remedies the evidence of negotiations would clearly be admissible to prove exhaustion.

Evidence Code section 354 states in part that “[a] verdict or finding shall not be set aside, nor shall the judgment or decision based thereon be reversed, by reason of the erroneous exclusion of evidence unless ... it appears of record that (a) the substance, purpose, and relevance of the excluded evidence was made known to the court . . . .” Thus when evidence is offered on an inadmissible basis, its exclusion is not reversible error. (Witkin, Cal. Evidence (2d ed. 1966) p. 280.) The court may, of course, admit the evidence despite the mistaken theory of its proponent, but in such event fairness may require that the court disclose the limited purpose for which it is admitting the evidence.

After the court had admitted the exhibits into evidence, defendant called Mr. Gill to explain his action and the action of the Board of Public Works respecting the proposed change order. At various times during trial, other witnesses referred to the exhibits without objection. Plaintiff contends that this testimony constitutes a waiver by defendant of its objection to admission of the exhibits, or, alternatively, that it makes any error in their admission non-prejudicial since the content of the documents was substantially repeated béfore the jury in the oral testimony.
The principle stated in
Fernandez
v.
Western Fuse etc. Co.
(1917)
The jury rendered a general verdict against defendant, and some cases hold that “even though the evidence may not be sufficient to sustain a cause of action ... a reversal may not be had upon that ground if the evidence as to other causes of action . . . is sufficient to sustain the verdict.”
(Caccamo
v.
Swanston
(1949)
“Defendant also notes that Mr. Warner testified that “my procedure would have been about the same” if the plans had contained no test-hole information. Subsequent testimony by Warner indicated that “procedure” referred to the construction method, and that Warner relied on the data both in computing its bid and in not undertaking further independent investigation of subsoil conditions.
Plaintiff asserts that Warner estimated the original cost of the job at $72,000, and that the final cost was $156,349.53, making an additional cost due to the city’s misrepresentations of $84,349.53. This computation is erroneous. The $72,000 does not include the additions resulting from the five change orders, and includes no sum for lost profits; the $156,349.53 figure takes account of the change orders and includes the estimated profit on the contract, but no claim for a reasonable profit on the additional work necessitated by use of rotary mud.

Examples of such references are:
“$184,000 isn’t very much as against $60,000,000. On the other hand, it’s a tidy sum of money. . . . It’s what the damages are fairly shown by the evidence . . . you will find it’s the cost of doing business."
*303 “Who should stand the loss between the contractor with that character and that determination and that purpose in life and that belief in the truth or should a great wealthy municipal corporation spending $60,000,000 a year for such things who have conducted themselves as you have seen in this case?”
“Of course, $100,000 is only peanuts on this operation. You heard Mr. Gill testify that he is spending some $60,000,000 a year. Another witness said they had some $3,000,000 in the capital improvement fund. That isn’t the test how much a person has. The test is what was the damage.”
“Are we going to say the king can do no wrong and Mr. Warner stands the $184,000, his family, his corporation—can it stand that loss or does it come out of the $60,000,000 a year that Mr. Gill is spending. I think there’s a strong moral here. I think that a government has to be honest with its subjects. There must be a truthfulness, a certain faith, a certain integrity between the city and the individual because if the city is dishonest then what can we tell our children?”
Unlike Horn, counsel did request that the jury be admonished to disregard the alleged improper statements. Defendant submitted an instruction, stating as it did so its belief that the instruction would not cure the prejudicial effect of the misconduct. The court refused the instruction on the ground that instructions against verdicts based on passion or prejudice, and prohibiting punitive damages, were sufficient.
